Description

[Technical field]

[0001] The present disclosure relates to a technique for controlling a slave station in a broadcast wireless system. [Background technology]

[0002] In the following description, in a broadcast wireless system, a device that wirelessly transmits information to be broadcast is referred to as a master station device. A device that receives wirelessly transmitted information from the master station device and broadcasts the received information, for example, by voice, is referred to as a slave station device. In the most basic configuration, all slave station devices that receive information wirelessly from the master station device broadcast the information as soon as they receive it. However, flexibility is required in the timing at which slave devices broadcast and in the selection of slave devices that will broadcast.

[0003] Patent Document 1 discloses a disaster prevention administrative radio system in which the master station device can specify the content and period of display performed by the slave station device. In the system of Patent Document 1, the master station device transmits the display content and the display start date and time and the display end date and time to the slave station device in advance, and the slave station device starts displaying the display content at the display start date and time and ends the display at the display end date and time.

[0004] Patent Document 2 discloses a broadcast wireless system in which a master station specifies the volume of a voice report made by a slave station for each report. The master station in Patent Document 2 transmits information related to the volume designation by radio. The slave station determines the voice volume based on the received information.

[0005] Patent Document 3 discloses a wireless broadcasting system in which a master station device can change broadcast target stations, etc. The master station device of Patent Document 3 selects a slave station device to which the master station device is to broadcast for each broadcast type, and specifies the slave station device to which the master station device is to broadcast by the identification information of the slave station device. Patent Document 3 also describes automatic broadcasting and manual broadcasting. An automatic broadcasting refers to a broadcasting by a broadcasting signal transmitted according to a schedule preset in the master station device. A manual broadcasting refers to a broadcasting by a broadcasting signal transmitted manually by an administrator of the master station device. The administrator of the master station device sets a priority for the manual broadcasting. When a slave station device receives an automatic broadcasting signal and a manual broadcasting signal, the slave station device broadcasts according to the received signal in the same manner. When a slave station device receives an automatic broadcasting signal and a manual broadcasting signal in the same time zone, the slave station device broadcasts either an automatic broadcasting or a manual broadcasting according to the priority set by the administrator of the master station device.

[0006] Patent Documents 4 and 5 disclose wireless communication systems in which a slave station device processes message information to perform effective reporting in the slave device.

[0007] Patent Document 6 discloses a broadcast wireless system in which a slave station device receives broadcast content information and repeat instruction information, and repeats a broadcast based on the broadcast content information, based on the repeat instruction information.

[0009] In the broadcast wireless systems of Patent Documents 1 to 6, the slave station devices broadcast according to conditions specified by the master station device. Therefore, in the techniques described in Patent Documents 1 to 6, even if the listeners of the slave station devices are in a state that is inconvenient for listening to the broadcast, it is not possible to stop the slave station devices from broadcasting according to the conditions specified by the master station device.

[0010] An object of the present disclosure is to provide a slave station device or the like that can suppress broadcasting when a broadcast listener is in an inconvenient state for listening to the broadcasting. [Means for solving the problem]

[0012] A child station control method according to one aspect of the present disclosure receives a signal representing broadcast content from a parent station device, determines whether the received broadcast content is real-time broadcast content that is specified to be output in response to being received, stores the real-time broadcast content in a broadcast content storage means, receives an output execution instruction from a user, and, if the output execution instruction is received, outputs the broadcast content stored in the broadcast content storage means.

[0013] A program according to one embodiment of the present disclosure causes a computer to execute a signal reception process that receives a signal representing broadcast content from a parent station device, a determination process that determines whether the received broadcast content is real-time broadcast content, which is the broadcast content that is specified to be output upon reception, and stores the real-time broadcast content in a broadcast content storage means, an instruction reception process that receives an output execution instruction from a user, and an output control process that outputs the broadcast content stored in the broadcast content storage means when the output execution instruction is received.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Before describing the embodiments of the present disclosure, a broadcast wireless system will be described in more detail.

[0017] Standards for general broadcast radio systems are disclosed, for example, in the following documents 1 and 2.

[0018] (Reference 1) ARIB STD-T86 Standard for Municipal Digital Broadcasting Systems Version 3.1 (Association of Radio Industries and Businesses) (Reference 2) Municipal Digital Broadcasting System TYPE2 Standard ARIB STD-T115 Version 2.1 (Association of Radio Industries and Businesses) In a general broadcast radio system, a retransmission slave station device, an outdoor loudspeaker slave station, and a home receiver correspond to the slave station device in the description of the present disclosure. A plurality of slave station devices can be installed in one broadcast radio system, and receive radio signals from the master station device to perform loudspeaker broadcasting. When broadcasting, an operator of the master station device selects an identifier of the slave station device to be broadcasted (hereinafter, slave station number) or an identifier that is set in the plurality of slave station devices to be broadcasted and can be set in the plurality of slave station devices (hereinafter, group number) and issues a broadcast start instruction. At that time, the operator of the master station device also selects a broadcast sound source such as a real voice, an artificial voice, a chime sound, or a siren sound as necessary. In that case, the master station device converts the broadcast start instruction and, if a broadcast sound source is selected, the broadcast sound source into a radio signal and transmits it.

[0019] More specifically, the master station device can specify one or more slave station numbers and group numbers in a radio signal (hereinafter, broadcast instruction signal) that is sent once or more for one broadcast, such as a broadcast start instruction or a broadcast sound source. The master station device can also specify a mixture of slave station numbers and group numbers. For convenience, one or more slave station numbers, group numbers, or both are referred to as slave station call numbers. When the slave station device receives a broadcast instruction signal from the master station device, it compares the slave station call numbers registered in the slave station device with the slave station call numbers specified in the broadcast instruction. Then, if there is a slave station call number specified in the broadcast instruction signal that matches the slave station call number registered in the slave station device, the slave station device performs loudspeaker broadcasting, and if there is no matching number, the slave station device does not perform loudspeaker broadcasting.

[0020] In a typical broadcast radio system, a test sound source may be amplified at a fixed time every day for normal loudspeaker broadcast testing. For example, a typical operation is to play chimes or music at noon or in the evening. In a municipality formed by merging multiple cities, towns, and villages, the following operation may also be performed. Recorded test sound sources for the former city, town, and village are stored in advance in each slave station device. The master station device transmits a broadcast instruction signal to the slave station devices to play the recorded test sound source. Upon receiving such a broadcast instruction signal, each slave station device simultaneously broadcasts a different sound source for each former city, town, and village.

[0021] Also, for example, in the event of a disaster, the master station device may transmit a broadcast instruction signal including real voice data or artificial voice data. In that case, the slave station device performs loudspeaker broadcasting using the real voice data or artificial voice data included in the broadcast instruction signal received from the master station device. Furthermore, the slave station device may store voice data in which a warning sound or a standard phrase is recorded in advance. In this case, the master station device transmits a broadcast instruction signal to the slave station device to play the pre-recorded warning sound or standard phrase. When the slave station device receives a broadcast instruction signal from the master station device to play the pre-recorded warning sound or standard phrase, the slave station device loudspeaks the sound source of the pre-recorded warning sound or standard phrase. When the master station device performs an emergency broadcast such as in the event of a disaster, the master station device may be set to add information indicating that the broadcast is an emergency broadcast to the broadcast instruction signal it transmits. When the slave station device responding to such a broadcast instruction signal receives a broadcast instruction signal to which information indicating that the broadcast is an emergency broadcast is added, it blinks a light or an LED (Light Emmitting Diode) to draw attention.

[0022] In this way, in a typical broadcast radio system, the slave station device receives a radio signal from the master station device and performs loudspeaker broadcasting. The slave station device further calls attention by turning on or blinking a light or LED as necessary. In other words, in a typical broadcast radio system, the slave station device broadcasts according to an instruction from the master station device, so loudspeaker broadcasting is performed regardless of the convenience of people who listen to the broadcast from the slave station device (hereinafter, broadcast listeners). Therefore, there is a problem that broadcast listeners may feel that loudspeaker broadcasts are "noisy" depending on the frequency, content, volume, and timing of the loudspeaker broadcast. However, if the master station device takes measures such as reducing the frequency of loudspeaker broadcasts or lowering the volume in order to solve this problem, another problem arises in that other broadcast listeners may feel that "the broadcast did not sound" or "the broadcast cannot be heard."

[0023] Some of the patent documents are described in more detail below.

[0024] Patent Documents 4 and 5 disclose a technique in which a center station device, which is a master station device, transmits text message information to a slave station device, which processes the message information, and performs loudspeaker broadcasting based on the processed message information. In this technique, necessary information can be provided for each slave station device using a broadcast instruction signal transmitted from the master station device, information held by the slave station device, and information acquired by the slave station device. In this technique, information such as the name of a river pre-recorded for each slave station device, information acquired from a telemeter device connected to the slave station device, and message information from the master station device are combined by processing the message information. By broadcasting the message information processed in this way, loudspeaker broadcasting with different contents for each slave station device is possible. However, in the techniques described in Patent Documents 4 and 5, when loudspeaker broadcasting is performed, the frequency and number of times of loudspeaker broadcasting follow instructions from the master station device. Therefore, loudspeaker broadcasting is performed even when it is inconvenient for broadcast listeners to listen to the broadcast.

[0025] Patent Document 6 describes a technique in which a slave station device autonomously performs repeated broadcasting, which is normally performed according to a broadcast instruction signal transmitted from a master station device. In this technique, the slave station device repeats loudspeaker broadcasting based on information on the number of repetitions and the repetition interval instructed by the master station device. By suppressing the frequency of transmitting the broadcast instruction signal from the master station device, efficient system operation becomes possible. In the technique described in Patent Document 6, the slave station device also performs loudspeaker broadcasting according to instructions from the master station device. Therefore, loudspeaker broadcasting is performed even when it is inconvenient for broadcast listeners to listen to the broadcast.

[0026] As described above, general broadcast radio systems and broadcast radio systems described in the above-mentioned patent documents are designed on the assumption that the slave station devices will perform loudspeaker broadcasting. As information sources for loudspeaker broadcasting, various information is used, such as information recorded in the slave station devices, character information, text information, real voice information, artificial voice information, and sensor information of external devices connected to the slave station devices, such as telemeters, transmitted from the master station devices. However, in any case, the slave station devices broadcast when they receive a broadcast instruction signal from the master station devices or when the sensor of the external device connected to the slave station devices exceeds a threshold value. As a result, loudspeaker broadcasting is performed regardless of the convenience of the broadcast listeners.

[0027] In addition, since the slave station device generally consumes a lot of power during loudspeaker broadcasting, the time that loudspeaker broadcasting can be performed during a power outage is limited. If the frequency of loudspeaker broadcasting increases, the battery of the slave station device will be consumed, and there is a concern that the slave station device will be shut down sooner during a power outage. In order to reduce the battery consumption of the slave station device, even if the master station device monitors the water level and precipitation of the river, it is necessary to reduce frequent transmission of the monitored information, which is information on the process of changing the situation, to the slave station device. The master station device will broadcast only the alert level, evacuation recommendation, and evacuation instruction, which are information resulting from the change in the situation. As a result, the broadcast listeners will need to obtain information on the process of changing the situation regarding the water level and precipitation of the river by means other than the broadcast from the slave station device, such as the Internet, television, and radio. The broadcast listeners will need to obtain information resulting from the change in the situation, such as the alert level, evacuation recommendation, and evacuation instruction, from the slave station device of the broadcast radio system. If the broadcast listeners collect information inconsistently in this way, there is a possibility that they will make delayed or incorrect decisions regarding evacuation actions.

[0028] In this way, in times of disaster, listeners of general broadcast radio systems collect information that changes over time from their personal information terminals, relying on the Internet and broadcaster content, while also collecting instructions from the government from slave station devices. In other words, listeners of general broadcast radio systems collect information using two different types of media. Therefore, even if evacuation orders are issued from one media, evacuation may be delayed due to comparison with information from the other media, further information gathering, time taken to make a decision before evacuation, and disregard for evacuation orders.

[0029] Furthermore, in general, a slave station device can perform its own broadcast (hereinafter, its own broadcast) by operating the slave station device even without an instruction from the master station device. If the slave station device receives a broadcast instruction signal from the master station device while a broadcast listener is operating the slave station device (for example, playing a own broadcast, which is a broadcast of information detected by the slave station device using a sensor), the slave station device forcibly interrupts the operation of the broadcast listener. Then, the slave station device broadcasts the broadcast content according to the broadcast instruction signal received from the master station device by loudspeaker. That is, in general, the operation of the slave station device by the broadcast listener is restricted by the broadcast instruction from the master station device. In other words, in general, even if a broadcast listener of the slave station device is in an inconvenient state for viewing a broadcast according to a broadcast instruction from the master station device, the slave station device performs a broadcast according to a broadcast instruction from the master station device.

[0030] <First embodiment> First, a first embodiment of the present disclosure will be described.

[0031] <Configuration> 1 is a block diagram illustrating an example of a configuration of a slave station device 10 according to a first embodiment of the present disclosure. In the example illustrated in FIG. 1, the slave station device 10 includes a signal receiving unit 110, a determination unit 120, a broadcast content storage unit 130, an output control unit 140, and an instruction receiving unit 150.

[0032] The signal receiving unit 110 receives a signal representing broadcast contents from the parent station device. In the following description, the broadcast contents represent information instructed by the parent station to be broadcast. The determining unit 120 determines whether the received broadcast contents are real-time broadcast contents, which are the broadcast contents designated to be output in response to being received, and stores the real-time broadcast contents in the broadcast contents storage means. In the following description, the real-time broadcast contents are broadcast contents that are assumed to be output immediately (in other words, in real time) by the child station device received from the parent station device. In further words, the real-time broadcast contents are broadcast contents that, in the case of a general broadcast wireless system, the child station device is set to broadcast immediately upon receiving from the parent station device. If the child station device of the general broadcast wireless system is set to immediately broadcast broadcast contents for which no date and time related to the broadcast is set, the real-time broadcast contents include broadcast contents for which no date and time related to the broadcast is set. Broadcast contents that are not real-time broadcast contents are, for example, broadcast contents designated to be broadcast at a specified time. In the following description of the embodiments of the present disclosure, "broadcast" represents the above-mentioned loudspeaker broadcast by the child station device. The broadcast content storage unit 130 stores the real-time broadcast content. The instruction receiving unit 150 receives an output execution instruction from a user. The user is the broadcast listener of the slave station device described above. When the output control unit 140 receives the output execution instruction, it outputs the broadcast content stored in the broadcast content storage means. The output control unit 140 outputs the broadcast content by loudspeaking the broadcast content using an output device such as a speaker. The first embodiment of the present disclosure may be further configured as any of the embodiments described below.

[0033] <Operation> 2 is a flowchart illustrating an example of the operation of the slave station device 10 according to the first embodiment of the present disclosure. Note that this embodiment may be further configured as any of the embodiments described below.

[0034] 2, first, the signal receiving unit 110 receives a signal representing broadcast contents, in other words, a signal of the broadcast contents (step S11). The determination unit 120 determines whether the received broadcast contents are real-time broadcast contents (step S12). If the received broadcast contents are real-time broadcast contents, the received broadcast contents, i.e., the received real-time broadcast contents, are stored in the broadcast contents storage unit 130 (step S13).

[0035] The instruction receiving unit 150 receives an output instruction from the user (step S14). If real-time broadcast content is stored in the broadcast content storage unit 130 (YES in step S15), the output control unit 140 outputs the real-time broadcast content stored in the broadcast content storage unit 130 (step S16). As described above, the output control unit 140 outputs the real-time broadcast content by loudspeaking the real-time broadcast content using an output device such as a speaker. Then, the slave station device 10 ends the operation shown in FIG. 2. If real-time broadcast content is not stored in the broadcast content storage unit 130 (NO in step S15), the slave station device 10 also ends the operation shown in FIG. 2.

[0036] <Effects> This embodiment has an effect of suppressing broadcasts when the broadcast listener is in an inconvenient state for listening to the broadcasts. This is because the determination unit 120 determines whether the received broadcast contents are real-time broadcast contents, which are broadcast contents to be output in response to reception, and stores the real-time broadcast contents in the broadcast contents storage unit 130. Then, when an output instruction from a user, i.e., a broadcast listener, is received, the output control unit 140 outputs the real-time broadcast contents using an output device.

[0037] <Second embodiment> Next, a second embodiment of the present disclosure will be described in detail with reference to the drawings.

[0038] <Overall> FIG. 3 is a block diagram showing a schematic configuration of a broadcast wireless system 1 according to a second embodiment of the present disclosure. In the example shown in FIG. 3, the broadcast wireless system 1 includes a master station device 200 and a plurality of slave station devices 100. The master station device 200 transmits a signal representing broadcast contents to each of the slave station devices 100 by wireless. Specifically, the master station device 200 automatically or manually transmits a broadcast instruction signal including water level information of a river as broadcast contents, for example, every 5 minutes, to each of the slave station devices 100 via a wireless antenna. The broadcast instruction signal may include a slave station call signal. Each of the slave station devices 100 is assigned a different slave station call number. The slave station devices 100 store the assigned slave station call number.

[0039] The broadcast content may include the type of information represented by the broadcast content and the value of that information. The type of information is, for example, the water level of a river. In this case, the value of the information is the value of the water level of the river. The type of information may be other types of values, such as the amount of precipitation per unit time, the accumulated amount of precipitation over 24 hours, the risk of landslides, the risk of river flooding, etc. The value of the information is a value measured or set as the value of this information. The type of information is not limited to the above examples. The type of information does not have to include at least any of the above examples.

[0040] The broadcast content may be assigned attributes of the broadcast content. In other words, the broadcast content may include attributes of the broadcast content. The attributes may include the slave station call number described above. The attributes may include a broadcast start date and time. The attributes may include a broadcast end date and time. The broadcast start date and time and the broadcast end date and time are collectively referred to as a broadcast date and time designation. The attributes may include information indicating that the broadcast content is to be preferentially broadcast in loudspeaker. The attributes may include information indicating whether or not the content is to be broadcast in loudspeaker.

[0041] <Slave station device 100> Fig. 4 is a block diagram illustrating an example of a configuration of a slave station device 100 according to the second embodiment of the present disclosure. In the example illustrated in Fig. 4, the slave station device 100 includes a signal receiving unit 110, a determination unit 120, a broadcast content storage unit 130, an output control unit 140, an instruction receiving unit 150, an output unit 160, and a list output unit 170.

[0042] <Signal Reception Unit 110> The signal receiving unit 110 receives a signal indicating broadcast contents from the master station device (i.e., a broadcast instruction signal). For example, the signal receiving unit 110 compares a slave station call number included in the broadcast instruction signal with a stored slave station call number, and if the slave station call number included in the broadcast instruction signal is the same as the stored slave station call number, the signal receiving unit 110 receives the broadcast instruction signal.

[0043] The signal receiving unit 110 sends the broadcast content represented by the received broadcast instruction signal to the determining unit 120. As described above, in the description of this embodiment, the broadcast content includes the attributes of the broadcast content.

[0044] <Judgment section 120> The determination unit 120 receives from the signal receiving unit 110 the broadcast content indicated by the broadcast instruction signal.

[0045] The determination unit 120 determines whether the received broadcast content satisfies the criteria (hereinafter referred to as the priority criteria or the second criteria) for the broadcast content specified to be preferentially broadcast amplified. The priority criteria may be, for example, a condition for the attributes of the broadcast content. The priority criteria may be a condition for the broadcast content. The priority criteria may be a condition for both the broadcast content and the attributes of the broadcast content. If the received broadcast content satisfies the priority criteria, the determination unit 120 sends the broadcast content to the output control unit 140.

[0046] The determination unit 120 further determines whether the received broadcast content is real-time broadcast content. If the received broadcast content is not real-time broadcast (for example, in this embodiment, if the broadcast content is a broadcast content with a specified broadcast date and time), the determination unit 120 stores the broadcast content in the broadcast content storage unit 130. In this case, the broadcast content includes an attribute including a specified broadcast date and time. That is, the determination unit stores the broadcast content and the specified broadcast date and time of the broadcast content in the broadcast content storage unit 130.

[0047] If the received broadcast content is real-time broadcast content, the determination unit 120 determines whether the received broadcast content satisfies a criterion (hereinafter, referred to as an emergency criterion or a first criterion) for determining whether to immediately output the broadcast content. Specifically, the determination unit 120 first compares the received broadcast content with a comparison target stored in the broadcast content storage unit 130. The comparison target is a real-time broadcast content to be compared with the next real-time broadcast content. More specifically, the determination unit 120 calculates a difference between a value of a predetermined piece of information represented by the received broadcast content and a value of a predetermined piece of information represented by the comparison target. For example, if the broadcast content is the water level of a river, the determination unit 120 calculates a difference between the water level of the river represented by the comparison target and the water level of the underline represented by the received real-time broadcast content. The determination unit 120 determines whether a result of comparing the received broadcast content with the comparison target stored in the broadcast content storage unit 130 satisfies the emergency criterion. More specifically, the determination unit 120 determines whether a difference between a value of information represented by the received broadcast content and a value of information represented by the comparison target is greater than a threshold value. For example, the urgency criterion may be that the difference is greater than a threshold value. The urgency criterion may be that the difference is smaller than a threshold value. A plurality of urgency criteria may be defined. In this embodiment, the comparison target is the latest real-time broadcast content among the real-time broadcast contents stored in the broadcast content storage unit 130.

[0048] If the received broadcast content satisfies the emergency criteria, the determination unit 120 sends the received broadcast content to the output control unit 140. If multiple emergency criteria are defined, the determination unit 120 sends the broadcast content and the emergency criteria that the broadcast content satisfies to the output control unit 140. If the received broadcast content does not satisfy the emergency criteria, the determination unit 120 does not send the received broadcast content to the output control unit 140.

[0049] The determination unit 120 further stores the received broadcast content, which is the real-time broadcast content, in the broadcast content storage unit 130 as a comparison target. When real-time broadcast content of the same type as the received real-time broadcast content is stored in the broadcast content storage unit 130, the determination unit 120 may overwrite the real-time broadcast content stored in the broadcast content storage unit 130 with the received real-time broadcast content of the same type as the real-time broadcast content. In other words, the determination unit 120 may replace the real-time broadcast content stored in the broadcast content storage unit 130 with the received real-time broadcast content of the same type as the real-time broadcast content. The determination unit 120 may add the received real-time broadcast content to the broadcast content storage unit 130 so that a plurality of real-time broadcast contents received at a plurality of different time points are stored in the broadcast content storage unit 130.

[0050] <Output unit 160> The output unit 160 is an output device described in the description of the present disclosure that outputs broadcast contents.

[0051] <List output section 170> The list output unit 170 outputs a list of the broadcast contents stored in the broadcast content storage unit 130 to a display device such as a display or a touch panel. The list output unit 170 may output the list of the broadcast contents stored in the broadcast content storage unit 130 when the instruction receiving unit 150 described later receives a request for a list of the broadcast contents stored in the broadcast content storage unit 130.

[0052] <Instruction Receiving Unit 150> The instruction receiving unit 150 may receive a request for a list of broadcast contents stored in the broadcast content storage unit 130 .

[0053] The instruction receiving unit 150 receives an output instruction from a user using an input device of the slave station device 100 .

[0054] The input device may be, for example, a loudspeaker button that instructs output of broadcast contents (for example, loudspeaker broadcast) by pressing it. The input device may be a motion sensor that detects the presence of a person. In that case, the instruction receiving unit 150 may determine that the output instruction has been received when a person is detected by the motion sensor. The input device may be a camera. In that case, the instruction receiving unit 150 may perform face authentication using preregistered face information of a user in an image captured by the camera. In that case, the instruction receiving unit 150 may determine that the output instruction has been received when the face authentication is successful. In addition, when the input device is a camera, the instruction receiving unit 150 may determine whether a person appearing in the captured image is making a specific gesture or pose. The instruction receiving unit 150 may determine that the output instruction has been received when it is determined that a person appearing in the image is making a specific gesture or pose. The input device may be a microphone. In that case, the instruction receiving unit 150 may determine that the output instruction has been received when a predetermined voice is input. The predetermined sound may be, for example, a sound of a predetermined frequency. The predetermined sound may be a spoken instruction. In this case, the instruction receiving unit 150 may perform voice recognition, determine whether the recognized sound is an output instruction, and determine that the output instruction has been received if the recognized sound is an output instruction. In the above cases, the instruction receiving unit 150 determines that the most recent broadcast content has been specified.

[0055] The input device may be a touch panel that also operates as the list output unit 170. In this case, the instruction receiving unit 150 may receive, as an output instruction, a designation of broadcast content using the touch panel.

[0056] The instruction receiving unit 150 notifies the output control unit 140 that the output instruction has been received. If broadcast content is specified, the instruction receiving unit 150 notifies the output control unit 140 of information on the specified broadcast content.

[0057] <Output control unit 140> When an output instruction is accepted, i.e., when notified that an output instruction has been accepted, the output control unit 140 outputs the real-time broadcast contents stored in the broadcast content storage unit 130 using an output device. When notified of information on the specified broadcast contents, the output control unit 140 outputs the specified broadcast contents from among the real-time broadcast contents stored in the broadcast content storage unit 130. When notified of information on the specified broadcast contents, the output control unit 140 outputs the most recent real-time broadcast contents from among the real-time broadcast contents stored in the broadcast content storage unit 130.

[0058] The output control unit 140 further receives broadcast content from the determination unit 120. The broadcast content received from the determination unit 120 is broadcast content that satisfies the priority criteria or the urgency criteria. The output control unit 140 outputs the broadcast content received from the determination unit 120. The output control unit 140 may receive, from the determination unit 120, information on the broadcast content and the urgency criteria that the broadcast content satisfies. In this case, the output control unit 140 may output the broadcast content in a different manner depending on the urgency criteria represented by the received information.

[0059] When the broadcast content with the specified broadcast date and time is stored in the broadcast content storage unit 130, the output control unit 140 outputs the broadcast content with the specified broadcast date and time according to the specified broadcast date and time.

[0060] When the attribute of the broadcast content indicates that loudspeaker broadcasting is to be performed, the output device is a loudspeaker. The output control unit 140 outputs the real-time broadcast content by performing loudspeaker broadcasting that generates a sound represented by the real-time broadcast content to be output from the loudspeaker.

[0061] When the attribute of the broadcast content indicates that loudspeaker broadcasting is not performed, the output device may be an LED. The output device may be a speaker. The output device may be a motor that generates vibrations. The output device may be a heater that generates heat. The output device may be a device that generates a specific odor. The output device may be an information terminal device communicably connected to the slave station device 100. The output device is not limited to these examples. The output device may be a combination of at least any of these examples. The output control unit 140 may output the real-time broadcast content by emitting light from an LED. The color, intensity, and light emission pattern of the light emitted by the LED may be predetermined according to the real-time broadcast content. The output control unit 140 may light up the LED with different colors, intensities, and light emission patterns, for example, when the water level of a river is falling and when the water level is rising. The output control unit 140 may output the real-time broadcast content by generating a specific sound from a speaker. In this case, the output control unit 140 may generate sounds of different predetermined patterns according to the real-time broadcast content. When the output device is an information terminal device, the output control unit 140 may transmit characters, figures, symbols, etc., representing the real-time broadcast content to the information terminal device.

[0062] <Operation> Next, the operation of the slave station device 100 according to the second embodiment of the present disclosure will be described in detail with reference to the drawings.

[0063] FIG. 5 is a flowchart showing an example of the overall operation of the slave station device 100 according to the second embodiment of the present disclosure when broadcast content is received. In the example shown in FIG. 5, first, the signal receiving unit 110 receives a signal of the broadcast content (step S101). Next, the slave station device 100 performs broadcast content processing (step S102). The broadcast content processing will be described in detail later. Next, the slave station device 100 determines whether to end the operation (step S103). For example, when the remaining battery power is depleted or when an instruction to end the operation is given by a user, the slave station device 100 determines to end the operation. If the operation is not to be ended (NO in step S104), the operation of the slave station device 100 returns to step S101. If the operation is to be ended (YES in step S104), the operation of the slave station device 100 shown in FIG. 5 ends.

[0064] FIG. 6 is a flowchart illustrating an example of an operation of broadcast content processing of the slave station device 100 according to the second embodiment of the present disclosure.

[0065] In the example shown in Fig. 6, first, the determination unit 120 determines whether the received broadcast content satisfies the priority criteria (step S111). If the received broadcast content satisfies the priority criteria (YES in step S112), the determination unit 120 sends the received broadcast content to the output control unit 140. The output control unit 140 receives the broadcast content from the determination unit 120, and outputs the received broadcast content using an output device (step S119). Then, the slave station device 100 ends the operation shown in Fig. 6.

[0066] If the received broadcast content does not satisfy the priority criteria (NO in step S112), the determination unit 120 determines whether the received broadcast content is real-time broadcast content (step S113). If the received broadcast content is not real-time broadcast content (NO in step S114), the broadcast content is, for example, broadcast content with a specified broadcast date and time. In this case, the determination unit 120 stores the broadcast date and time and the broadcast content in the broadcast content storage unit 130 (step S115). Then, the slave station device 100 ends the operation shown in FIG. 6.

[0067] If the received broadcast content is real-time broadcast content (YES in step S114), the determination unit 120 determines whether the real-time broadcast content (i.e., the received broadcast content) satisfies the urgency criteria (step S116). The determination unit 120 stores the real-time broadcast content (i.e., the received broadcast content) in the broadcast content storage unit 130 as a comparison target (step S117).

[0068] If the result of the determination in step S116 is that the real-time broadcast content satisfies the urgency criteria (YES in step S118), the determination unit 120 sends the real-time broadcast content (i.e., the received broadcast content) to the output control unit 140. The output control unit 140 receives the broadcast content from the determination unit 120, and outputs the received broadcast content using an output device (step S119). Then, the slave station device 100 ends the operation shown in FIG. 6.

[0069] If the result of the determination in step S116 is that the real-time broadcast content does not satisfy the urgency criteria (NO in step S118), the slave station device 100 ends the operation shown in FIG.

[0070] Fig. 7 is a flowchart showing an example of an operation of the slave station device 100 when receiving an output instruction according to the second embodiment of the present disclosure. The slave station device 100 may perform the operation shown in Fig. 7 in parallel with the operations shown in Figs. 5 and 6.

[0071] 7, first, the instruction receiving unit 150 receives an output instruction input by a user. In other words, the instruction receiving unit 150 receives an output instruction (step S121). The instruction receiving unit 150 notifies the output control unit 140 that the output instruction has been received.

[0072] The output control unit 140 determines whether or not real-time broadcast content is stored in the broadcast content storage unit 130 (step S122). If real-time broadcast content is not stored in the broadcast content storage unit 130 (NO in step S123), the slave station device 100 ends the operation shown in FIG.

[0073] If no real-time broadcast content is stored in the broadcast content storage unit 130 (YES in step S123), the output control unit 140 uses an output device to output the real-time broadcast content stored in the broadcast content storage unit 130 (step S124). If the output instruction specifies the real-time broadcast content to be output, the output control unit 140 outputs the real-time broadcast content specified in the output instruction. If the output instruction does not specify the real-time broadcast content to be output, the output control unit 140 outputs the most recent real-time broadcast content.

[0074] <Effects> This embodiment has the same effects as the first embodiment, for the same reasons that the effects of the first embodiment are obtained.

[0075] The effects of this embodiment will be described in further detail below.

[0076] In this embodiment, the water level information transmitted from the master station device 200 to the slave station device 100 every 5 minutes, for example, can be checked by the slave station device 100 at any time by the broadcast listeners. If a water level sensor is connected to the slave station device 100, it is possible to grasp only the increase or decrease in the water level measured by the water level sensor without checking the broadcast content itself. Furthermore, when an evacuation recommendation or warning is issued due to a rise in the water level, the master station device 200 broadcasts using a general broadcast instruction signal, and the slave station device 100 broadcasts with loudspeakers, making it possible to reliably provide the information to the broadcast listeners. Therefore, it is possible to provide information in a more detailed and flexible manner than with a general system.

[0077] That is, in this embodiment, the operator of the master station device 200 can appropriately distribute disaster-related information when necessary, without worrying about complaints from broadcast listeners about the frequency, timing, volume, and the like of broadcasts. Also, in a typical system, the number and frequency of broadcasts from the master station device 200 is reduced during a power outage due to concerns about battery consumption in the slave station device 100. However, in this embodiment, information can be transmitted without loudspeaker broadcasting. This improves the battery life of the slave station device 100. Furthermore, it becomes possible to transmit information from the master station device 200 at the timing when information transmission should be performed, without worrying about battery consumption.

[0078] Furthermore, broadcast listeners can obtain information that changes over time and instructions from the government as consistent information from the same medium. This eliminates the problem that users of general systems have, that when an evacuation order is issued from one medium, it takes time to make a decision before evacuation because they have to compare it with information from the other medium or collect additional information. Broadcast listeners can then understand the content and background of the evacuation order and evacuate quickly using only the information obtained from the slave station device 100.

[0079] As described in the description of this embodiment, when the slave station device 100 receives a broadcast instruction signal and records information about the broadcast contents in the recording unit of the slave station device 100, the slave station device 100 performs the operation of recording the information about the broadcast contents in the recording unit of the slave station device 100 while remaining in standby mode. This allows the slave station device 100 to transmit information from the master station device 200 without interfering with its behavior, even when the slave station device 100 is playing back a sound source recorded therein or when the slave station device 100 is broadcasting its own station. In other words, the system of this embodiment allows information distribution in a manner that does not interfere with the operation of the slave station device 100 by the broadcast listener.

[0080] <Third embodiment> Next, a third embodiment of the present disclosure will be described in detail with reference to the drawings. In the above-mentioned second embodiment, the comparison target is the latest real-time broadcast content among the real-time broadcast contents stored in the broadcast content storage unit 130. In this embodiment, the comparison target is the real-time broadcast content designated by the master station device 200 or the user (i.e., the broadcast listener).

[0081] <Configuration> 3 is a block diagram showing a configuration of a broadcast wireless system 1 according to a third embodiment of the present disclosure. The configuration of the broadcast wireless system 1 of this embodiment is the same as the configuration of the broadcast wireless system 1 of the second embodiment. The broadcast wireless system 1 of this embodiment is the same as the broadcast wireless system 1 of the second embodiment, except for the differences in the slave station device 100 and the master station device 200, which will be described below.

[0082] <Master station device 200> The master station device 200 of this embodiment adds information indicating that the broadcast content is a comparison target to the broadcast content designated as a comparison target, and transmits the broadcast content with the added information indicating that the broadcast content is a comparison target to each slave station device 100. The master station device 200 transmits broadcast content not designated as a comparison target without adding information indicating that the broadcast content is a comparison target. The information indicating that the broadcast content is a comparison target may be included in the attributes. The information indicating that the broadcast content is a comparison target may not be included in the broadcast content. In that case, the master station device 200 may transmit the information indicating that the broadcast content is a comparison target to each slave station device 100 together with the broadcast content. In other respects, the master station device 200 of this embodiment is the same as the master station device 200 of the second embodiment, and operates in the same manner as the master station device 200 of the second embodiment.

[0083] <Slave station device 100> 4 is a block diagram showing an example of a configuration of a slave station device 100 according to a third embodiment of the present disclosure. The configuration of the slave station device 100 of this embodiment is the same as the configuration of the slave station device 100 of the second embodiment. The slave station device 100 of this embodiment is the same as the slave station device 100 of the second embodiment, except for the differences described below.

[0084] <Signal Reception Unit 110> The signal receiving unit 110 of the present disclosure receives broadcast content to which information indicating that it is a comparison target is not added, and also receives broadcast content to which information indicating that it is a comparison target is added.

[0085] <Judgment section 120> The determination unit 120 determines whether the broadcast content is designated as a comparison target. If information indicating that the broadcast content is a comparison target is added to the broadcast content, the determination unit 120 determines that the broadcast content is designated as a comparison target. If information indicating that the broadcast content is a comparison target is not added to the broadcast content, the determination unit 120 determines that the broadcast content is not designated as a comparison target. The determination unit 120 stores the broadcast content designated as a comparison target in the broadcast content storage unit 130 as a comparison target.

[0086] <Instruction Receiving Unit 150> The instruction receiving unit 150 further receives a request for a list of broadcast contents stored in the broadcast content storage unit 130. When a request for a list of broadcast contents stored in the broadcast content storage unit 130 is received, the list output unit 170 outputs the list of broadcast contents. The instruction receiving unit 150 receives an instruction for a comparison target selected, for example, from the output list. The instruction for the comparison target is information indicating one of the broadcast contents stored in the broadcast content storage unit 130. The instruction receiving unit 150 sets the broadcast content indicated by the received instruction for the comparison target as the comparison target. In the configuration of the slave station device 100 shown in FIG. 5, the line between the instruction receiving unit 150 and the broadcast content storage unit 130 is omitted to avoid complicating the diagram.

[0087] <Operation> Next, an operation of the slave station device 100 according to the third embodiment of the present disclosure will be described.

[0088] Fig. 8 is a flowchart showing an example of the overall operation of the slave station device 100 according to the third embodiment of the present disclosure when broadcast content is received. Compared with the operation of the slave station device 100 of the second embodiment shown in Fig. 5, the slave station device 100 of this embodiment performs operations from step S202 to step S205 instead of the operation of step S102 shown in Fig. 5. The operations of steps S103 and S104 of the slave station device 100 of this embodiment are the same as the operations of the steps of the slave station device 100 of the second embodiment to which the same reference numerals are assigned.

[0089] 8, the signal receiving unit 110 receives a signal of broadcast content (step S101). In step S101, the signal receiving unit 110 receives broadcast content designated as a comparison target or broadcast content designated as a comparison target.

[0090] The determination unit 120 determines whether the received broadcast content is specified as a comparison target (step S202). If the received broadcast content is not specified as a comparison target (NO in step S203), the slave station device 100 next performs broadcast content processing (step S205). The broadcast content processing will be described in detail later.

[0091] If the received broadcast content is designated as a comparison target (YES in step S203), the determination unit 120 stores the received broadcast content in the broadcast content storage unit 130 as a comparison target (step S204). Then, the slave station device 100 next performs broadcast content processing (step S205).

[0092] In steps S103 and S104, the slave station device 100 of this embodiment performs the same operations as those in steps S103 and S104 of the slave station device 100 of the second embodiment.

[0093] Fig. 9 is a flowchart showing an example of the operation of broadcast content processing of the slave station device 100 according to the third embodiment of the present disclosure. Compared with the broadcast content processing of the slave station device 100 of the second embodiment shown in Fig. 6, the slave station device 100 of this embodiment performs the operation of step S217 instead of the operation of step S117. In steps S111 to S116, S118, and S119, the slave station device 100 of this embodiment performs the same operations as the operations of the steps of the slave station device 100 of the second embodiment to which the same reference numerals are assigned.

[0094] In step S217, the determination unit 120 stores the real-time broadcast content in the broadcast content storage unit 130. In step S217, the determination unit 120 does not take the real-time broadcast content as a comparison target.

[0095] 7 is a flowchart showing an example of an operation of the slave station device 100 when receiving an output instruction according to the third embodiment of the present disclosure. The operation of the slave station device 100 when receiving an output instruction according to the third embodiment of the present disclosure is the same as the operation of the slave station device 100 when receiving an output instruction according to the second embodiment.

[0096] FIG. 10 is a flowchart illustrating an example of an operation of the slave station device 100 according to the third embodiment of the present disclosure when an instruction for a comparison target is received.

[0097] 10, first, the instruction receiving unit 150 receives a request for a list of broadcast contents (step S221). When the request for the list of broadcast contents is received, the list output unit 170 displays the list of broadcast contents stored in the broadcast content storage unit 130 (step S222).

[0098] Next, the instruction receiving unit 150 receives an instruction for a comparison target (step S223). The instruction receiving unit 150 sets the broadcast content that is specified as a comparison target by the received instruction among the broadcast contents stored in the broadcast content storage unit 130 as a comparison target (step S224).

[0099] <Effects> This embodiment has the same effects as the first embodiment, for the same reasons that the effects of the first embodiment are obtained.

[0100] This embodiment has an advantage that the parent station device 200 and the user can flexibly set the comparison target. This is because the determination unit 120 stores the broadcast content specified by the parent station device 200 as the comparison target in the broadcast content storage unit 130, and the instruction acceptance unit 150 sets the broadcast content specified by the user as the comparison target.

[0101] <Fourth embodiment> Next, a fourth embodiment of the present disclosure will be described in detail with reference to the drawings. This embodiment is the same as the third embodiment, except for the differences described below.

[0102] In the third embodiment, the emergency criteria is set in advance in the slave station device 100 and is not changed. In the present embodiment, the emergency criteria is set by the user of the master station device 200 or the slave station device 100.

[0103] It should be noted that the differences between the third embodiment and the present embodiment, which will be described below, can also be applied to the second embodiment. In that case, in the following description, the third embodiment can be read as the second embodiment.

[0104] <Configuration> 3 is a block diagram showing an example of the configuration of a broadcast wireless system 1 according to a fourth embodiment of the present disclosure. The configuration of the broadcast wireless system 1 of this embodiment is the same as the configuration of the broadcast wireless system 1 of the third embodiment. The broadcast wireless system 1 of this embodiment is the same as the broadcast wireless system 1 of the third embodiment, except for the differences described below.

[0105] <Master station device 200> The master station device 200 of this embodiment has the same functions as the master station device of the third embodiment and performs the same operations as the master station device of the third embodiment. The master station device 200 of this embodiment further transmits a signal indicating an emergency criterion to each of the slave station devices 100, for example, by an operation by an administrator of the master station device 200.

[0106] <Slave station device 100> The slave station device 100 of this embodiment is the same as the slave station device 100 of the third embodiment except for the differences described below. The slave station device 100 of this embodiment performs the same operations as the slave station device 100 of the third embodiment. The slave station device 100 of this embodiment additionally performs the operations described below.

[0107] <Configuration> 4 is a block diagram showing an example of a configuration of a slave station device 100 according to a fourth embodiment of the present disclosure. The configuration of the slave station device 100 of this embodiment is the same as the configuration of the slave station device 100 of the third embodiment. The following describes differences between the slave station device 100 of this embodiment and the slave station device 100 of the third embodiment.

[0108] <Signal Reception Unit 110> The signal reception unit 110 has the same functions as the signal reception unit 110 of the third embodiment. The signal reception unit 110 further receives a signal indicating an emergency criterion from the master station device 200. The signal reception unit 110 sends the received emergency criterion to the determination unit 120.

[0109] <Instruction Receiving Unit 150> The instruction receiving unit 150 has the same function as the instruction receiving unit 150 of the third embodiment. The instruction receiving unit 150 further receives an instruction indicating the emergency criteria from a user via an input device of the slave station device 100. The input device is, for example, a touch panel, an information terminal connected to the slave station device 100, a microphone, etc. When the input device is a microphone, the instruction receiving unit 150 recognizes the instruction indicating the emergency criteria by performing voice recognition on the voice data input by the microphone.

[0110] The instruction receiving unit 150 sends the emergency criteria represented by the received instruction to the determination unit 120.

[0111] <Judgment unit 120> The determination unit 120 of this embodiment has the same functions as the determination unit 120 of the third embodiment. The determination unit 120 of this embodiment additionally has the following functions.

[0112] The determination unit 120 receives the emergency criterion from the signal receiving unit 110. When the determination unit 120 receives the emergency criterion from the signal receiving unit 110, the determination unit 120 updates the emergency criterion used for the determination with the emergency criterion represented by the received signal, i.e., the emergency criterion received from the signal receiving unit 110.

[0113] Furthermore, the determination unit 120 receives an emergency criterion from the instruction receiving unit 150. Upon receiving the emergency criterion, the determination unit 120 updates the emergency criterion used for the determination with the emergency criterion represented by the received signal, i.e., the emergency criterion received by the instruction receiving unit 150.

[0114] That is, the determination unit 120 uses a preset emergency criterion for the determination when it has not received an emergency criterion from the signal reception unit 110 and the instruction reception unit 150. When the determination unit 120 receives an emergency criterion from at least one of the signal reception unit 110 and the instruction reception unit 150, it makes the determination using the most recently received emergency criterion.

[0115] <Operation> The slave station device 100 of this embodiment performs the same operations as the slave station device 100 of the third embodiment. In addition, the slave station device 100 of this embodiment performs the operations described below.

[0116] Fig. 11 is a flowchart showing an example of a first operation of the slave station device 100 according to the fourth embodiment of the present disclosure to receive a signal indicating an emergency criterion. In the example shown in Fig. 11, first, the signal reception unit 110 receives a signal indicating an emergency criterion from the master station device 200 (step S301). If the signal indicating the emergency criterion is not received (NO in step S302), the slave station device 100 of this embodiment ends the operation shown in Fig. 11.

[0117] When the signal indicating the emergency criterion is received (YES in step S302), the determination unit 120 updates the emergency criterion used for the determination with the emergency criterion indicated by the received signal (step S303). Then, the slave station device 100 of the present embodiment ends the operation shown in FIG.

[0118] The slave station device 100 of this embodiment may perform the operation shown in FIG. 11 in parallel with other operations.

[0119] Fig. 12 is a flowchart showing an example of a second operation of the slave station device 100 according to the fourth embodiment of the present disclosure to receive an instruction indicating an emergency criterion. In the example shown in Fig. 12, first, the instruction receiving unit 150 receives an instruction indicating an emergency criterion from a user via, for example, an input device (step S311). If the instruction indicating the emergency criterion is not received (NO in step S312), the slave station device 100 of this embodiment ends the operation shown in Fig. 12.

[0120] When an instruction indicating the emergency criterion is received (YES in step S312), the determination unit 120 updates the emergency criterion used for the determination by the emergency criterion indicated by the instruction received by the instruction receiving unit 150 (step S313). Then, the slave station device 100 of this embodiment ends the operation shown in FIG.

[0121] The slave station device 100 of this embodiment may perform the operation shown in FIG. 12 in parallel with other operations.

[0122] <Effects> This embodiment has the same effects as the third embodiment, for the same reasons as those for the third embodiment.

[0123] This embodiment has the advantage that the emergency criterion can be flexibly set because the determination unit 120 makes a determination using the most recent emergency criterion among the emergency criterion indicated by the signal received by the signal receiving unit 110 and the emergency criterion indicated by the instruction received by the instruction receiving unit 150.

[0124] <Fifth embodiment> Next, the fifth embodiment of the present disclosure will be described in detail with reference to the drawings. This embodiment is the same as the fourth embodiment, except for the differences described below.

[0125] It should be noted that the differences between the fourth embodiment and this embodiment can also be applied to the second and third embodiments. When the differences between the fourth embodiment and this embodiment are applied to the second embodiment, the fourth embodiment in the following description can be read as the second embodiment. When the differences between the fourth embodiment and this embodiment are applied to the third embodiment, the fourth embodiment in the following description can be read as the third embodiment.

[0126] <Configuration> 13 is a block diagram illustrating an example of the configuration of a broadcast wireless system 2 according to a fifth embodiment of the present disclosure. The configuration of the broadcast wireless system 1 of this embodiment is the same as the configuration of the broadcast wireless system 1 of the fourth embodiment, except that the slave station device 100 is replaced by a slave station device 101. The broadcast wireless system 2 of this embodiment is the same as the broadcast wireless system 1 of the fourth embodiment, except for the differences described below.

[0127] In this embodiment, the slave station device 101 can wirelessly transmit data to the master station device 200. In this embodiment, the slave station device 101 may be configured to transmit data to the master station device 200 via another communication network.

[0128] <Slave station device 101> Fig. 14 is a diagram illustrating an example of the configuration of a slave station device 101 according to a fifth embodiment of the present disclosure. The slave station device 101 of this embodiment includes a calculation unit 180 and a transmission unit 190 in addition to the components of the slave station device 100 of the fourth embodiment shown in Fig. 4. The slave station device 101 of this embodiment is the same as the slave station device 100 of the fourth embodiment except for the differences described below.

[0129] <Judgment section 120> The determination unit 120 of the present disclosure associates the real-time broadcast content stored in the broadcast content storage unit 130 with the time at which the signal of the real-time broadcast content was accepted. In other words, the determination unit 120 stores the real-time broadcast content and the time at which the signal of the real-time broadcast content associated with the real-time broadcast content was accepted in the broadcast content storage unit 130. Note that the time associated with the real-time broadcast content may be the time at which the determination unit 120 received the real-time broadcast content from the signal acceptance unit 110. The time associated with the real-time broadcast content may be the time at which the determination unit 120 stores the real-time broadcast content in the broadcast content storage unit 130. In the following, a case will be described where the time associated with the real-time broadcast content is the time at which the signal of the real-time broadcast content was accepted.

[0130] <Calculation unit 180> The calculation unit 180 calculates the time from when the signal representing the real-time broadcast content is received until the real-time broadcast content is output. Note that the calculation unit 180 may determine that the real-time broadcast content has not been output if a predetermined time (also referred to as a child station confirmation threshold) has elapsed since the signal representing the real-time broadcast content was received.

[0131] <Transmitter 190> The transmitting unit 190 transmits the time from when the signal representing the real-time broadcast content is accepted to when the real-time broadcast content is output to the master station device 200. If there is real-time broadcast content that has been determined not to have been output, the transmitting unit 190 notifies the master station device 200 that the real-time broadcast content has not been output.

[0132] <Operation> The slave station device 101 of this embodiment operates in the same manner as in the fourth embodiment, except for the operation of receiving an output instruction.

[0133] FIG. 15 is a flowchart illustrating an example of an operation of the slave station device 101 according to the fifth embodiment of the present disclosure to receive an output instruction.

[0134] 15, the instruction receiving unit 150 detects an input of an output instruction (step S401). When an input of an output instruction is detected (YES in step S402), the slave station device 101 of this embodiment performs operations from step S121 to step S124. The operations from step S121 to step S124 of the slave station device 101 of this embodiment are the same as the operations from step S121 to step S124 of the slave station device 101 of the fourth embodiment shown in FIG.

[0135] Next, the calculation unit 180 calculates the time from when the signal representing the real-time broadcast content is accepted to when the real-time broadcast content is output. The transmission unit 190 transmits the time from when the signal representing the real-time broadcast content is accepted to when the real-time broadcast content is output to the master station device 200 (step S403). Then, the slave station device 101 of this embodiment ends the operation shown in FIG. 15.

[0136] If no output instruction input is detected (NO in step S402), the slave station device 101 of this embodiment detects real-time broadcast contents stored in the broadcast content storage unit 130 for which a predetermined time (i.e., the time represented by the slave station confirmation threshold) has elapsed since the signal was accepted (step S404). If the real-time broadcast contents for which a predetermined time has elapsed since the signal was accepted are not stored in the broadcast content storage unit 130 (NO in step S404), the slave station device 101 of this embodiment ends the operation shown in FIG.

[0137] If the real-time broadcast content for which a predetermined time has elapsed since the signal was received is stored in the broadcast content storage unit 130 (YES in step S404), the transmitting unit 190 notifies the master station device 200 that the real-time broadcast content has not been output (step S405).

[0138] <Effects> This embodiment has the same effects as the fourth embodiment, for the same reasons as those for the fourth embodiment.

[0139] This embodiment has an effect of enabling more efficient system operation. The reason is that the transmitting unit 190 transmits to the master station device 200 the time calculated by the calculating unit 180 from when the signal representing the real-time broadcast content is received until the real-time broadcast content is output. The master station device 200 (more precisely, the manager of the master station device 200) can obtain information from one or more slave station devices 101 as to whether or not the broadcast listeners have confirmed information related to the broadcast content. By statistically treating the obtained information, the master station device 200 can grasp what percentage of the broadcast listeners have confirmed the content broadcast by the no-audio-broadcast instruction signal. The master station device 200 can review the frequency and content of broadcasts by the no-audio-broadcast instruction signal based on the obtained information.

[0140] Sixth embodiment Next, a sixth embodiment of the present disclosure will be described in detail with reference to the drawings. In this embodiment, the priority criteria is updated according to a user's instruction. This embodiment is the same as the fifth embodiment, except for the following differences.

[0141] It should be noted that the difference between the fifth embodiment and the present embodiment can also be applied to the second, third, and fourth embodiments. In that case, in the following description, the fifth embodiment can be read as the second, third, or fourth embodiment.

[0142] <Configuration> <Broadcast Radio System 2> 13 is a block diagram illustrating an example of a configuration of a broadcast wireless system 2 according to a sixth embodiment of the present disclosure. The configuration of the broadcast wireless system 2 of this embodiment is the same as the configuration of the broadcast wireless system 2 of the fifth embodiment. The broadcast wireless system 2 of this embodiment is the same as the broadcast wireless system 2 of the fifth embodiment, except for the differences described below.

[0143] <Slave station device 101> 14 is a block diagram illustrating an example of a configuration of a slave station device 101 according to a sixth embodiment of the present disclosure. The configuration of the slave station device 101 according to the sixth embodiment of the present disclosure is the same as the configuration of the fifth embodiment. The slave station device 101 of this embodiment is the same as the slave station device 101 of the fifth embodiment, except for the differences described below.

[0144] <Instruction Receiving Unit 150> The instruction receiving unit 150 of this embodiment has the same functions as the instruction receiving unit 150 of the fifth embodiment. The instruction receiving unit 150 of this embodiment further receives an instruction indicating a priority criterion. The instruction receiving unit 150 sends the priority criterion, for which the instruction has been received, to the determination unit 120.

[0145] <Judgment section 120> The determination unit 120 of this embodiment has the same functions as the determination unit 120 of the fifth embodiment. The determination unit 120 of this embodiment further receives, from the instruction receiving unit 150, a priority criterion represented by an instruction received by the instruction receiving unit 150, and updates the priority criterion used for determination by the priority criterion represented by the received instruction.

[0146] The priority criterion may be a condition for the type of slave station call number included in the broadcast instruction signal. The priority criterion may be a condition for the priority of broadcasts such as general broadcasts and emergency broadcasts. The priority criterion may be a condition for the type of broadcasts such as automatic broadcasts and manual broadcasts. The priority criterion may be a condition for the type of broadcast sound source such as live voice broadcasts, artificial voice broadcasts, and specific sound sources. The priority criterion may be a condition for the type of broadcast instruction signal such as a non-amplified broadcast instruction signal or a conventional broadcast instruction signal. The priority criterion may be a condition for the time period in which the broadcast is received. The priority criterion may be a condition for information obtained from a human presence sensor or the like connected to the slave station device 101. The priority criterion may be a condition for the supply status of commercial power to the slave station device 101.

[0147] The determination unit 120 may perform a determination based on the truth or falsity of any one of the conditions of the above-mentioned priority criteria. The determination unit 120 may perform a determination using a combination, a logical sum, a logical product, an exclusive logical sum, or an exclusive logical product of any two or more of the above-mentioned priority criteria.

[0148] Since households with infants and small children often prefer less frequent broadcasts, it is assumed that the slave station device 101 installed in the home will treat only the amplified broadcast instruction signal, which has a broadcast priority of emergency broadcast, as the amplified broadcast instruction signal. It is assumed that the priority criteria in the slave station will be set so that other non-amplified broadcast instruction signals or amplified broadcast instruction signals will be treated as non-amplified broadcast instruction signals.

[0149] In addition, in a situation where there is no power outage, if a broadcast listener wants the river water level information transmitted from the master station device 200 to be broadcast in loudspeaker form from the slave station device 101 every time, it is expected that the priority criteria will be set in the slave station device 100 so that even if a no-amplified broadcast instruction signal is received, it will be treated as a broadcast instruction signal for amplified broadcast.

[0150] <Operation> The operation of the sixth embodiment of the present disclosure is the same as that of the fifth embodiment, except for the operation described below. The slave station device 101 according to the sixth embodiment of the present disclosure performs the same operation as that of the slave station device 101 according to the fifth embodiment.

[0151] Fig. 16 is a flowchart showing an example of an operation of the slave station device 101 according to the sixth embodiment of the present disclosure to receive a priority criterion. In the example shown in Fig. 16, the instruction receiving unit 150 receives an instruction representing a priority criterion (step S501). If the instruction representing the priority criterion is not received (NO in step S502), the slave station device 101 according to the present embodiment ends the operation shown in Fig. 16.

[0152] If an instruction indicating a priority criterion is received (YES in step S502), the determination unit 120 updates the priority criterion used for determination with the priority criterion indicated by the received instruction (step S503).

[0153] <Effects> This embodiment has the same effects as those of the fifth embodiment, for the same reasons as those for the effects of the fifth embodiment.

[0154] This embodiment also has the advantage that the system can be operated more appropriately in accordance with the needs of broadcast listeners. This is because the instruction receiving unit 150 receives an instruction for a priority criterion. Then, the judgment unit 120 updates the priority criterion used for judgment by the judgment criterion represented by the received instruction.
