However, creating information for media is a burden on local governments in times of emergency such as disasters. Therefore, an object of the present disclosure is to provide a broadcasting system and a broadcast aggregation analysis system that can reduce the burden on those who transmit information.

Means for Solving the Problems

[0005] (1) A broadcasting system that solves the problem comprises a broadcasting device that transmits an announcement voice signal to a loudspeaker, and an information transmission device that transmits broadcast-related information formed based on the announcement voice signal to an information distribution system, wherein the information distribution system is configured to classify provided information acquired from outside the system according to classification items, select information belonging to pre-selected selected classification items from the provided information, and transmit the selected information to registered users, wherein the information transmission device comprises an acquisition unit that acquires the announcement voice signal, an information formation unit that forms announcement information indicating the content of the announcement voice signal based on the announcement voice signal, a storage unit that stores classification information corresponding to the classification items of the information distribution system, a classification assignment unit that assigns the classification information related to the announcement information to the announcement information, a package unit that forms the broadcast-related information from the announcement information and the classification information, and a transmission unit that transmits the broadcast-related information to the information distribution system as provided information.

[0006] With this configuration, the broadcasting system can generate broadcast-related information based on the announcement audio signal along with the broadcast. The broadcast-related information is transmitted to the information distribution system by the transmission unit. This eliminates the effort required to create the information to be provided to the information distribution system, thus reducing the burden on those transmitting the information.

[0007] (2) In the broadcasting system described in (1) above, the classification items include regional classification items for classifying the provided information by region, and the classification information includes regional classification information corresponding to the regional classification items. With this configuration, the information distribution system can provide information about the region selected by a person who has selected one or more regions as selected classification items from the regional classification items.

[0008] (3) In the broadcasting system described in (2) above, the information transmission device has a first selection unit that selects one of a plurality of regional classification information pre-registered as classification information based on the user's operation, and the classification assignment unit assigns the regional classification information selected by the first selection unit to the announcement information. With this configuration, the regional classification information to be assigned to the announcement information can be selected by the first selection unit.

[0009] (4) In the broadcasting system described in any one of (1) to (3) above, the memory unit stores the unique regional classification information as classification information, and the classification assignment unit assigns the unique regional classification information as classification information to the announcement information. With this configuration, the regional classification information assigned to the announcement information is fixed to one. Therefore, the effort of selecting regional classification information can be eliminated.

With this configuration, the content analysis unit identifies content classification information related to the announcement information, thus reducing the effort required to select content classification information.

[0014] (9) In the broadcasting system described in any one of (1) to (8) above, the information forming unit extracts words from the announcement audio signal and converts the extracted words into text to form the announcement information including text information. With this configuration, announcement information including text can be formed. This makes it possible to provide broadcast-related information including text to the information distribution system. Compared to the case of audio, the content of the information can be grasped by the users of the information distribution system in a shorter time.

[0015] (10) In the broadcasting system described in any one of (1) to (9) above, the information forming unit extracts the portion containing words from the announcement audio signal as sound and forms the announcement information composed of the audio signal. With this configuration, announcement information including an audio signal can be formed. This makes it possible to provide broadcast-related information including an audio signal to the information distribution system. In this case, information can be transmitted to a visually impaired person.

[0016] (11) A broadcast aggregation and analysis system that solves the problem comprises a plurality of broadcast systems described in any one of (1) to (10), and a prediction device that predicts the state of other regions based on the broadcast-related information obtained from each of the plurality of broadcast systems, wherein the plurality of broadcast systems are installed in different regions. With this configuration, it is possible to predict the future state of other regions.

[0017] (12) In the broadcast aggregation and analysis system described in (11) above, the information distribution system is configured to classify the information provided from outside the system according to classification items, select information belonging to pre-selected selected classification items from the information provided, and transmit the selected information to registered users.

[Modes for carrying out the invention]

[0022] <First Embodiment> The broadcasting system 1 according to this embodiment will be described with reference to Figures 1 to 12. Figure 1 is a schematic diagram showing the entire information transmission system IT. The information transmission system IT shows the transmission route for disaster-related information (hereinafter referred to as disaster information). The information transmission system IT includes the broadcasting system 1 and the information distribution system 2. Disaster information includes disaster occurrence information, forecasts indicating the possibility of a disaster occurring, warning information regarding disasters, information indicating dangers caused by disasters, evacuation orders, evacuation advisories, information on the opening of evacuation centers, and traffic information related to disasters. In this embodiment, disasters include natural disasters and man-made disasters. For example, disasters include earthquake disasters, tsunami disasters, volcanic eruptions, landslides, river flooding, building or mountain fires, chemical plant fires, infrastructure information related to disasters, missile launch information, and information on nuclear accidents. The information transmission system IT may also be used to transmit information other than disasters to people. Information unrelated to disasters includes information on heatstroke, infrastructure information (power outages, gas or water service disruptions, and information on water supply locations), and information on missing persons issued by the police (requests for information, information on the whereabouts of missing persons).

[0023] As shown in Figures 1 and 2, the broadcasting system 1 comprises a broadcasting device 10 and an information transmission device 20. The broadcasting device 10 is one transmission system in the information transmission IT system. The broadcasting device 10 directly transmits disaster information to people within the broadcasting area using sound.

[0024] [Broadcasting equipment] The broadcasting device 10 is used for the purpose of conveying disaster information to people. The broadcasting device 10 may also be used for purposes other than conveying disaster information. For example, the broadcasting device 10 may be used to play music.

[0025] The broadcasting device 10 transmits an announcement voice signal AS to the loudspeaker 3. The announcement voice signal AS may be an analog or digital signal. The broadcasting device 10 is installed inside a designated building. The broadcasting device 10 is used to convey disaster information to people.

[0026] For example, the broadcasting device 10 may be used by a local government disaster prevention officer to convey disaster information to nearby residents. Alternatively, the broadcasting device 10 may be used by a building manager to convey disaster information to people inside the building.

[0027] As shown in Figure 1, the broadcasting device 10 comprises a microphone 11 and a main unit 12. The microphone 11 converts speech into an audio signal. The main unit 12 amplifies and modulates the audio signal and outputs the amplified audio signal to the public address system 3. The main unit 12 transmits the amplified audio signal to the public address system 3 via wired or wireless connection. The public address system 3 produces sound by reproducing the amplified audio signal. The wired connection may be a dedicated line or a connection via the Internet or other network.

[0028] The announcement voice signal AS is an example of an audio signal. The announcement voice signal AS is a signal related to an announcement. The announcement voice signal AS is an audio signal that occurs when audio, including an announcement, is converted into an electrical signal by the microphone 11. The announcement includes words to be conveyed to people. An example of an announcement is a disaster announcement, which includes disaster information. Disaster announcements are made when there is a risk of disaster or during a disaster (hereinafter, these are collectively referred to as "when a disaster occurs"). For example, when a disaster occurs, a disaster announcement may be made by a local government disaster prevention officer to nearby residents using the broadcasting device 10. Alternatively, when a disaster occurs, a disaster announcement may be made by a building manager to people inside the building using the broadcasting device 10.

[0029] The public address system 3 includes one or more speakers 4. The multiple speakers 4 are connected to the main unit 12 of the broadcasting device 10 by wire or wireless. The speakers 4 are installed outdoors. For example, the speakers 4 are installed on utility poles, transmission towers, the rooftops of public facilities, government buildings, private factories, or private shops. Residents within the broadcasting area can learn that a disaster is imminent from the disaster information broadcast from the speakers 4.

[0030] Since the broadcasting device 10 can be constructed using the technology of conventional broadcasting devices 10, a detailed explanation thereof will be omitted. Similarly, since the communication connecting the broadcasting device 10 and the loudspeaker device 3 is the same as conventional communication technology, a detailed explanation thereof will also be omitted.

[0031] [Information distribution system] Information distribution system 2 is a system that transmits disaster information to registered users' terminals 5 via network N. Terminals 5 include mobile terminals or personal computers installed on desks. Mobile terminals include personal computers or smart terminals. Smart terminals include smartphones, tablets, and notebook personal computers. Information distribution system 2 distributes information to registered users as follows. Network N is the internet, a telephone line network, or a composite network in which these are connected.

[0032] Information distribution system 2 classifies the provided information PI obtained from outside the system according to classification item CA. "Outside the system" refers to information transmission systems or devices other than information distribution system 2. This includes information terminals of the Japan Meteorological Agency, information terminals of traffic information centers, information terminals of organizations that transmit disaster information, and personal information terminals. An example of provided information PI is disaster information. Disaster information includes earthquakes, special weather warnings, railway traffic information during disasters, road traffic information during disasters, etc.

[0033] Information distribution system 2 may acquire information other than disaster information from outside the system. In this case, the provided information PI includes traffic information that occurs regardless of the disaster. For example, regarding railways, the provided information PI may include information on service suspensions due to accidents involving people or problems with vehicles or track equipment, information on alternative train services, train delays, and information on the resumption of train services. Regarding aviation, the provided information PI may include information on aircraft operation status (such as the possibility of returning to the departure point due to "weather surveys" or sailing to a destination other than the destination), cancellations due to aircraft scheduling issues, and booking issues. Regarding shipping, the provided information PI may include information on ship operation status.

[0034] In the information distribution system 2, classification item CA is pre-configured. Classification item CA is an item used to classify information. Classification item CA includes the regional classification item CB. Furthermore, classification item CA includes the content classification item CC.

[0035] The regional classification item CB is used to classify the provided information PI by region. The region indicates the area related to the content of the provided information PI. Specifically, if the provided information PI is disaster information, the region indicates the area where the disaster is occurring. If the provided information PI is traffic-related information and indicates a road closure, the region indicates the area where the road closure is occurring.

[0036] As shown in Figure 3, in one example, the regional classification item CB is composed of the names of cities, towns, and villages throughout Japan. The regional classification item CB may also include city names. The regional classification item CB may also include station names. The regional classification item CB may also include the names of well-known facilities.

[0037] Content classification item CC is used to classify the provided information PI according to its content. Specifically, if the provided information PI indicates the occurrence of an earthquake, the content of the provided information PI is earthquake. If the provided information PI indicates a special weather warning such as heavy rain, the content of the provided information PI is a special weather warning.

[0038] For example, as shown in Figure 4, examples of content classification items CC include earthquakes, special weather warnings, traffic information (railways), and traffic information (roads). Furthermore, when information transmission IT is used to transmit information to people about matters other than disasters, other content classification items CC may also be set, such as flowering information, pollen information, yellow dust information, rainy season front, ultraviolet radiation information, autumn rain front, and sudden shower information.

[0039] Content classification items CC are not limited to the examples shown in Figure 4. For example, examples of content classification items CC include tsunamis, floods, heavy rain, wildfires, missile launch warnings, and nuclear accidents. Examples of content classification items CC other than disasters include heatstroke warnings, infrastructure shutdown information, and information from the police.

[0040] Information distribution system 2 accepts information PI. Information PI is configured to include regional classification information CY corresponding to regional classification item CB, and content classification information CZ corresponding to content classification item CC. The operator of information distribution system 2 announces to people in advance that regional classification information CY and content classification information CZ will be attached to the information PI when distributing information. For example, the operator obtains information PI with regional classification information CY and content classification information CZ attached by showing the format of the information PI. Information providers can use the format to provide the region as regional classification information CY and the content as content classification information CZ to information distribution system 2 along with the content they are providing. Information distribution system 2 obtains information PI from an unspecified number of people.

[0041] Information distribution system 2 is configured to select information belonging to selected classification item CD from the provided information PI and then transmit the selected information to registered users. Selected classification item CD is a classification item CA that has been pre-selected by the registered user from the classification items CA. By setting the selected classification item CD in this way, registered users can obtain only the information that corresponds to the selected classification item CD.

[0042] As shown in Figure 5, the information distribution system 2 has distribution destination information that associates the registered user's name, the registered user's address, and the selected classification item CD. By referring to this distribution destination information, the information distribution system 2 provides the registered user with information belonging to the selected classification item CD selected by the registered user.

[0043] An example of the operation of the information distribution system 2 will be explained with reference to Figures 6 and 7. When the information distribution system 2 acquires the information to be provided (PI), it saves the information to be provided (PI) to the database along with the acquisition time (see Figure 6). The information distribution system 2 then refers to the regional classification information (CY) and content classification information (CZ) attached to the information to be provided (PI) to obtain the regional classification item (CB) corresponding to the regional classification information (CY) and the content classification item (CC) corresponding to the content classification information (CZ). The information distribution system 2 then sends the information to be provided (PI) to registered users who have set the regional classification item (CB) and content classification item (CC) as selected classification items (CD). When this happens, a reception mark is displayed on the registered user's terminal (5). Based on the reception mark, when the registered user opens the application for the information distribution system 2, the information to be provided (PI) is displayed on the display screen (5A) of the terminal (see Figure 7). In this way, registered users can obtain information about the region and content they have selected from the information distribution system 2.

[0044] A concrete example of information distribution system 2 is a distribution system like "Yahoo! (registered trademark) Disaster Prevention Alerts" operated by Yahoo! Japan Corporation. Information distribution system 2 may also be capable of distributing other information in addition to disaster alerts.

[0045] [Information transmission device] The information transmission device 20 transmits broadcast-related information BI, formed based on the announcement voice signal AS, to the information distribution system 2 via the network N. As described above, the announcement voice signal AS is a signal related to an announcement. The announcement includes disaster information. Therefore, the broadcast-related information BI formed based on the announcement voice signal AS includes disaster information. By transmitting such broadcast-related information BI to the information distribution system 2, disaster information can be conveyed to people using the information distribution system 2.

[0046] As shown in Figure 8, the information transmission device 20 includes an acquisition unit 21, an information formation unit 22, a storage unit 23, a classification assignment unit 24, a packaging unit 25, and a transmission unit 26. In this embodiment, the information transmission device 20 further includes a first selection unit 27 and a second selection unit 28.

[0047] The information transmission device 20 is composed of one or more CPUs (Central Processing Units) or one or more MPUs (Micro Processing Units). The acquisition unit 21, information formation unit 22, classification assignment unit 24, packaging unit 25, and transmission unit 26, first selection unit 27, and second selection unit 28 may be some functions of the CPU or MPU. The storage unit 23 may include memory included in the CPU or MPU, or it may include external memory. The acquisition unit 21, information formation unit 22, classification assignment unit 24, packaging unit 25, and transmission unit 26 are configured to operate by the execution of a program stored in the memory of the CPU or MPU.

[0048] [Acquisition Department] The acquisition unit 21 acquires the announcement voice signal AS. Specifically, the acquisition unit 21 is connected to the broadcasting device 10. When a disaster announcement is input to the microphone 11 of the broadcasting device 10, the acquisition unit 21 acquires the announcement voice signal AS from the broadcasting device 10. The timing of the acquisition of the announcement voice signal AS by the user of the broadcasting system 1 may be determined by the user of the broadcasting system 1. For example, the acquisition unit 21 may have an acquisition button for acquiring the announcement voice signal AS. The acquisition button is configured so that when pressed, the announcement voice signal AS is transmitted to the acquisition unit 21 only for the duration that it is pressed. With the acquisition button, only disaster announcements can be made to be acquired by the acquisition unit 21.

[0049] [Information Formation Department] The information formation unit 22 will be explained with reference to Figure 9. The information formation unit 22 forms announcement information AI, which indicates the content of the announcement, based on the announcement voice signal AS.

[0050] For example, the information formation unit 22 extracts words from the announcement voice signal AS and converts the extracted words into text to form announcement information AI that includes text information. Word extraction is performed by the operation of a speech recognition program and a text conversion program. Word extraction may also be performed by using a speech recognition service on the cloud connected to the internet.

[0051] In the example shown in Figure 9, in the announcement audio signal AS, warning sounds that are added before and after the words indicating the announcement content are removed, and only the words are converted to text. The announcement information AI, which includes text information, is preferably displayed on the display unit of a personal computer. The announcement information AI, which includes text information, is preferably editable. For example, the announcement information AI may be stored on a personal computer connected to the information transmission device 20. With such a configuration, the announcement information AI can be edited on the personal computer. The announcement information AI, which includes text information, can provide the information distribution system 2 with the provided information PI, which includes text.

[0052] Furthermore, the information formation unit 22 may extract the portion containing words from the announcement voice signal AS as sound, and form announcement information AI composed of the voice signal. The extraction of sound from the portion containing words is performed by the operation of a speech recognition program. The sound extraction may also be performed by using a speech recognition service on the cloud connected to the internet. Sound extraction cuts out the portion containing words from the announcement voice signal AS. The portion other than words is, for example, a warning sound to draw attention. It is preferable that the announcement information AI containing sound related to words is playable. It is preferable that the announcement information AI containing sound related to words is editable. For example, the announcement information AI may be stored on a personal computer or smart terminal connected to the information transmission device 20. With such a configuration, the announcement information AI can be edited on the personal computer or smart terminal. With the announcement information AI containing sound related to words, the provided information PI including sound can be provided to the information distribution system 2.

[0053] [Storage] The memory unit 23 stores classification information CX corresponding to classification item CA of the information distribution system 2. Classification information CX includes regional classification information CY corresponding to regional classification item CB. It is preferable that regional classification information CY has a one-to-one correspondence with regional classification item CB. The number of regional classification information CYs may be less than or more than the number of regional classification item CBs. In other words, one or more of the multiple regional classification information CYs may not correspond to any of the regional classification item CBs.

[0054] Classification information CX includes content classification information CZ corresponding to content classification item CC. Preferably, content classification information CZ has a one-to-one correspondence with content classification item CC. The number of content classification information CZ may be less than or more than the number of content classification item CC. In other words, one or more of the multiple content classification information CZ may not correspond to any of the content classification item CC.

[0055] [Classification Assignment Section] The classification assignment unit 24 assigns classification information CX related to the announcement information AI to the announcement information AI. In this embodiment, the classification assignment unit 24 assigns the regional classification information CY selected by the first selection unit 27 to the announcement information AI. The classification assignment unit 24 assigns the content classification information CZ selected by the second selection unit 28 to the announcement information AI.

[0056] [First Selection Section] Referring to Figure 10, the first selection unit 27 will be explained. The first selection unit 27 is operated by the user. Based on the user's operation, the first selection unit 27 selects one of several regional classification information CYs that are pre-registered as classification information CX. Specifically, the first selection unit 27 is configured to select one regional classification information CY from several options of regional classification information CY. The regional classification information CYs displayed in the display unit of the first selection unit 27 are changed by moving the scroll bar. A regional classification information CY is selected when one of the multiple regional classification information CYs shown in the display unit of the first selection unit 27 is selected by the pointer. The regional classification information CY thus selected is assigned to the announcement information AI by the classification assignment unit 24. The timing of the selection of the regional classification information CY is when making a disaster announcement using the broadcasting device 10. Immediately after, immediately before, or during the implementation of a disaster announcement, the user uses the first selection unit 27 to select a region related to the disaster announcement from the options of regional classification information CY. In this case, the announcement information AI related to the disaster announcement is assigned regional classification information CY. For example, if the disaster announcement is information concerning a specific region, the name of that region is assigned to the announcement information AI as regional classification information CY.

[0057] [Second Selection Section] Referring to Figure 11, the second selection unit 28 will be explained. The second selection unit 28 is operated by the user. Based on the user's operation, the second selection unit 28 selects one of several content classification information CZs that are pre-registered as classification information CX. Specifically, the second selection unit 28 is configured to select one content classification information CZ from several options of content classification information CZs. The content classification information CZs displayed in the display unit of the second selection unit 28 are changed by moving the scroll bar. A content classification information CZ is selected when one of the multiple content classification information CZs shown in the display unit of the second selection unit 28 is selected by the pointer. The content classification information CZ thus selected is assigned to the announcement information AI by the classification assignment unit 24. The timing of selecting the content classification information CZ is when making a disaster announcement using the broadcasting device 10. Immediately after, immediately before, or during the implementation of a disaster announcement, the user uses the second selection unit 28 to select content related to the disaster announcement from the options of content classification information CZs. In this case, the AI ​​for disaster announcements is assigned content classification information CZ. For example, if a disaster announcement is related to a special weather warning, the AI ​​for announcements will be assigned "special weather warning" as content classification information CZ.

[0058] [Packaging Section] As shown in Figure 12, the package unit 25 forms broadcast-related information BI from announcement information AI and classification information CX. In one example, the package unit 25 forms broadcast-related information BI by packaging the announcement information AI and classification information CX. The package unit 25 forms broadcast-related information BI by combining the announcement information AI and classification information CX according to predetermined rules. The predetermined rules are rules configured in accordance with data formats that the information distribution system 2 can accept. That is, the package unit 25 forms broadcast-related information BI in a predetermined format so that the information distribution system 2 can accept the broadcast-related information BI as provided information PI. In another example, the package unit 25 creates a data structure that is essentially packaged by linking the announcement information AI and classification information CX to each other. With such an effective package, the announcement information AI and classification information CX can be transmitted as broadcast-related information BI with a time lag. The information transmitted with a time lag is combined by the receiving device. Alternatively, information transmitted with a time delay may be treated as related information by the receiving device.

[0059] [Transmitter] The transmitting unit 26 transmits broadcast-related information BI as provided information PI to the information distribution system 2. The transmitting unit 26 transmits the broadcast-related information BI to the information distribution system 2 at the time it is formed. Alternatively, the transmitting unit 26 may have a transmit button. In this example, the broadcast-related information BI is transmitted to the information distribution system 2 at the time the transmit button is pressed.

[0060] [Operation of this embodiment] Traditionally, during a disaster, local governments use conventional broadcasting equipment 10 to make disaster announcements to residents. However, information from local governments cannot be conveyed to people outside the broadcasting area. Therefore, local governments post content similar to disaster announcements on social media or update their websites to reach people outside the broadcasting area. However, in emergencies, when the situation changes moment by moment and manpower is often scarce, it is difficult to carry out these responses accurately and quickly.

[0061] According to the broadcasting system 1 of this embodiment, by using the broadcasting device 10 of the broadcasting system 1, broadcast-related information BI, which has content similar to a disaster announcement, can be transmitted to the information distribution system 2 along with the broadcast. The broadcast-related information BI is formed based on the announcement voice signal AS related to the disaster announcement, and the broadcast-related information BI is transmitted at the same time as the disaster announcement. Therefore, local government disaster prevention officials do not need to prepare data for the information distribution system 2 themselves, nor do they have to go through the trouble of transmitting it. In this way, the broadcasting system 1 can reduce the burden on local government disaster prevention officials. As a result, local government disaster prevention officials can provide disaster information to people in a timely manner, even as the situation changes moment by moment.

[0062] Broadcasting System 1 utilizes the existing information distribution system 2. Therefore, disaster information can be provided to existing registered users of Information Distribution System 2 without requiring people to register with Broadcasting System 1 for the purpose of receiving information from it. In this way, by utilizing the existing information distribution system 2, disaster information can be reliably provided to people without the need to publicize Broadcasting System 1 to the public.

[0063] [Effects of this embodiment] (1) The broadcasting system 1 comprises a broadcasting device 10 and an information transmission device 20. The information transmission device 20 has an information formation unit 22, a packaging unit 25, and a transmission unit 26. The information formation unit 22 forms announcement information AI, which indicates the announcement content of the announcement voice signal AS, based on the announcement voice signal AS. The packaging unit 25 forms broadcast-related information BI from the announcement information AI and classification information CX. The transmission unit 26 transmits the broadcast-related information BI as provided information PI to the information distribution system 2.

[0064] With this configuration, the broadcasting system 1 can generate broadcast-related information BI based on the announcement voice signal AS along with the broadcast. The broadcast-related information BI is transmitted to the information distribution system 2 by the transmission unit 26. This eliminates the need to create the information PI to be provided to the information distribution system 2, thereby reducing the burden on those who transmit information (for example, disaster prevention officials of local governments). In addition, the information distribution system 2 can provide information similar to the broadcast content to people outside the broadcast area.

[0065] (2) In the information distribution system 2, classification item CA includes regional classification item CB for classifying the provided information PI by region. In the broadcasting system 1, classification information CX includes regional classification information CY corresponding to regional classification item CB.

[0066] With this configuration, the information distribution system 2 can provide information about the region selected by a person who has selected one or more regions as selected classification items CD from the regional classification item CB.

[0067] (3) The information transmission device 20 has a first selection unit 27. The first selection unit 27 selects one of several regional classification information CYs that are pre-registered as classification information CX based on the user's operation. The classification assignment unit 24 assigns the regional classification information CY selected by the first selection unit 27 to the announcement information AI. With this configuration, the regional classification information CY to be assigned to the announcement information AI can be selected by the first selection unit 27. In this way, regional classification information CY can be easily assigned to the announcement information AI.

[0068] (4) In the information distribution system 2, classification item CA includes content classification item CC for classifying provided information PI according to the content of provided information PI. In the broadcasting system 1, classification information CX includes content classification information CZ corresponding to content classification item CC.

[0069] With this configuration, the information distribution system 2 can provide information about the content classification items CC selected by a person who has selected one or more content classification items CC as selected classification items CD from the content classification items CC.

[0070] (5) The information transmission device 20 has a second selection unit 28. The second selection unit 28 selects one of several content classification information CZs that are pre-registered as classification information CX based on the user's operation. The classification assignment unit 24 assigns the content classification information CZ selected by the second selection unit 28 to the announcement information AI. With this configuration, the content classification information CZ to be assigned to the announcement information AI can be selected by the second selection unit 28. In this way, content classification information CZ can be easily assigned to the announcement information AI.

[0071] (6) The information formation unit 22 extracts words from the announcement voice signal AS and converts the extracted words into text, thereby forming announcement information AI that includes text. With this configuration, announcement information AI that includes text can be formed. This makes it possible to provide broadcast-related information BI that includes text to the information distribution system 2. Compared to the case of voice, the content of the information can be grasped by the users of the information distribution system 2 in a shorter time.

[0072] (7) The information formation unit 22 may extract the portion containing words from the announcement voice signal AS as sound and form announcement information AI composed of the voice signal. With this configuration, announcement information AI including the voice signal can be formed. This makes it possible to provide broadcast-related information BI including the voice signal to the information distribution system 2. In this case, information can be transmitted to visually impaired persons.

[0073] <Second Embodiment> Referring to Figure 13, the broadcasting system 1 and information transmission system IT according to the second embodiment will be described. The information transmission system IT includes the broadcasting system 1 and the information distribution system 2. The information distribution system 2 is the same as that described in the first embodiment. In this embodiment, components common to the first embodiment are denoted by the same reference numerals as in the first embodiment, and the description of redundant components is omitted.

[0074] In the first embodiment, an information transmission device 20 is provided within the broadcasting system 1. However, in this embodiment, some of the functions of the information transmission device 20 are provided on a server 8 connected to the network N. Alternatively, all of the functions of the information transmission device 20 may be provided on the server 8 connected to the network N.

[0075] In this embodiment, the broadcasting system 1 comprises a broadcasting device 10 and an information transmission device 20. Of the components of the information transmission device 20, the storage unit 23X, the classification assignment unit 24X, the first selection unit 27X, and the second selection unit 28X are provided in the housing that houses the broadcasting device 10. The storage unit 23X, the classification assignment unit 24X, the first selection unit 27X, and the second selection unit 28X correspond to the configurations of the storage unit 23, the classification assignment unit 24, the first selection unit 27, and the second selection unit 28 shown in the first embodiment, respectively. The classification assignment unit 24X assigns the regional classification information CY selected by the first selection unit 27X to the announcement voice signal AS. The classification assignment unit 24X also assigns the content classification information CZ selected by the second selection unit 28X to the announcement voice signal AS.

[0076] The broadcasting device 10 transmits an announcement voice signal AS, regional classification information CY, and content classification information CZ related to disaster announcements to the server 8. The announcement voice signal AS is a signal obtained by converting an analog signal related to a disaster announcement into a digital signal. The regional classification information CY and content classification information CZ are linked to the announcement voice signal AS by the classification assignment unit 24X.

[0077] Regional classification information CY is information selected by the first selection unit 27X as a region related to disaster announcements, as shown in the first embodiment. Content classification information CZ is information selected by the second selection unit 28X as content related to disaster announcements, as shown in the first embodiment.

[0078] Server 8 is connected to the broadcasting device 10 via network N. Furthermore, Server 8 is connected to the information distribution system 2 via network N. Server 8 comprises an acquisition unit 21X, an information formation unit 22X, a packaging unit 25X, and a transmission unit 26X.

[0079] The acquisition unit 21X receives the announcement voice signal AS and classification information CX from the broadcasting device 10. The information formation unit 22X, the packaging unit 25X, and the transmission unit 26X each have configurations similar to those shown in the first embodiment. The information formation unit 22X extracts words from the announcement voice signal AS and converts the extracted words into text to form announcement information AI including text information. The packaging unit 25X forms broadcast-related information BI from the announcement information AI and classification information CX (regional classification information CY and content classification information CZ). The transmission unit 26X transmits the broadcast-related information BI as provided information PI to the information distribution system 2.

[0080] The above configuration also produces the same effects as the first embodiment. Furthermore, as a variation of the second embodiment, instead of the server 8 acquiring regional classification information CY and content classification information CZ from the broadcasting device 10, the server 8 itself may extract the region and content related to the disaster from the announcement information AI. The server 8 may then identify the regional classification information CY and content classification information CZ based on the extracted information (see Figures 20 and 21). In this case, the server 8 packages the identified regional classification information CY and content classification information CZ with the announcement information AI and transmits it to the information distribution system 2.

[0081] The broadcasting equipment 10 described above may be installed in various locations throughout Japan. The server 8 may be provided as a data center or cloud server. In this case, the server 8 receives announcement audio signals AS broadcast from the broadcasting equipment 10 throughout Japan, forms broadcast-related information BI for each, and transmits the broadcast-related information BI to the information distribution system 2. That is, the formation of broadcast-related information BI from announcement audio signals AS broadcast from the broadcasting equipment 10 in each location may be centrally performed by a server 8 on the cloud.

[0082] <Third Embodiment> The broadcast aggregation and analysis system 30 according to the third embodiment will be described with reference to Figures 14 to 18. In this embodiment, components common to the first embodiment are denoted by the same reference numerals as in the first embodiment, and the description of redundant components is omitted.

[0083] The broadcast aggregation and analysis system 30 collects disaster announcements from multiple broadcast systems 1 installed in several adjacent areas, and further predicts future information for other nearby areas based on the collected information. Furthermore, the broadcast aggregation and analysis system 30 transmits the predicted information as provided information PI to the information distribution system 2. An example of the broadcast aggregation and analysis system 30 is described below.

[0084] As shown in Figure 14, the broadcast aggregation and analysis system 30 comprises multiple broadcast systems 1 and a prediction device 40. Each of the multiple broadcast systems 1 is installed in a different region. Preferably, the multiple broadcast systems 1 are installed in regions adjacent to each other. One example of a combination of adjacent regions is a region including a plain, a region including an intermediate area between the plain and the forest, and a region including a mountainous area. In such regions, it may be possible to predict the disaster state in the mountainous area based on the disaster state in the plain and the intermediate area. Conversely, it may be possible to predict the disaster state in the plain and the intermediate area based on the disaster state in the mountainous area. For example, a chain reaction of disasters may occur, such as when a special weather warning for heavy rain is issued in a mountainous area, and then some time later, a flood warning is issued in the plain. The broadcast aggregation and analysis system 30 utilizes such past information to provide information related to disaster prediction.

[0085] [Prediction device] The prediction device 40 will be described with reference to Figure 15. The prediction device 40 predicts the status of other regions based on broadcast-related information BI acquired from each of the multiple broadcast systems 1. The prediction device 40 includes an acquisition unit 41, a prediction unit 42, a storage unit 43, a classification unit 44, a packaging unit 45, and a transmission unit 46.

[0086] The acquisition unit 41 acquires broadcast-related information BI from the broadcasting system 1. The broadcast-related information BI includes announcement information AI, regional classification information CY, and content classification information CZ. When a disaster announcement regarding a special weather warning is issued in one of several pre-configured regions, the acquisition unit 41 collects information continuously as follows: The acquisition unit 41 collects broadcast-related information BI issued from multiple regions over a predetermined period starting from the acquisition of the broadcast-related information BI related to the first disaster announcement. The predetermined period can be changed in the settings.

[0087] The prediction unit 42 forms prediction information FI by predicting the future state of other regions based on broadcast-related information BI of different regions. The broadcast-related information BI and future state are information related to disasters or traffic. In this embodiment, the broadcast-related information BI and future state are information related to disasters.

[0088] In one example, the prediction unit 42 analyzes the changes in the area where disaster information is issued (hereinafter referred to as "disaster information movement") over time, based on the time when broadcast-related information BI was acquired, regional classification information CY, and content classification information CZ. The disaster information movement analyzed by the prediction unit 42 is stored in the storage unit 43 and created a database each time disaster information is issued. The prediction unit 42 can refer to the stored disaster information movement. When disaster information is issued, the prediction unit 42 extracts the data of the closest disaster information movement from the disaster information movement database. Then, based on the extracted data, it identifies areas where disasters may occur in the future.

[0089] In another example, the prediction unit 42 uses a trained model 50 to predict the future state of other regions. The trained model 50 is a predictive model formed based on a database of broadcast-related BI information for multiple regions.

[0090] Refer to Figure 16 to explain the trained model 50. In the database, multiple broadcast-related information BIs about disasters occurring in a given region are managed as a single group of information (hereinafter referred to as group information GI) because they are related to each other. The group information GI is divided into pre-information, which occurred in the early to intermediate stages, and post-information, which occurred in the later stages. The pre-information is used as input data for training. The post-information is used as training data (see Figure 16). The trained model 50 is formed by deep learning based on the input data, output data based on the input data, and training data compared with the output data.

[0091] Referring to Figure 17, the operation of the prediction unit 42 when it has a trained model 50 will be explained. When the acquisition unit 41 acquires broadcast-related information BI from multiple regions, the prediction unit 42 inputs the broadcast-related information BI from multiple regions into the trained model 50. The trained model 50 then predicts the future state of other regions. The trained model 50 outputs the probability that other regions will reach a predetermined state. In one example, when a special heavy rain warning is issued in multiple adjacent regions, the prediction unit 42 outputs the probability of a special heavy rain warning being issued in other regions after a predetermined period. When the probability is greater than a predetermined value, the prediction unit 42 creates prediction information FI for the predicted region and identifies regional classification information CY and content classification information CZ. The prediction information FI includes a prediction of the disaster content and its probability of occurrence.

[0092] The memory unit 43 stores classification information CX corresponding to the classification item CA of the information distribution system 2. The memory unit 43 also databases and stores the movement of disaster information analyzed by the prediction unit 42. The classification assignment unit 44 assigns classification information CX related to the prediction information FI to the prediction information FI.

[0093] As shown in Figure 18, the packaging unit 45 forms broadcast-related forecast information BFI by packaging forecast information FI and classification information CX. Broadcast-related forecast information BFI includes regional classification information CY and content classification information CZ as classification information CX. The transmission unit 46 transmits broadcast-related forecast information BFI as provided information PI to the information distribution system 2.

[0094] [Effects of this embodiment] (1) The broadcast aggregation and analysis system 30 comprises a broadcast system 1 and a prediction device 40. The prediction device 40 predicts the state of other regions based on broadcast-related information BI acquired from each of the multiple broadcast systems 1. With this configuration, it is possible to predict the future state of other regions.

[0095] (2) The prediction device 40 includes a prediction unit 42, a classification unit 44, a packaging unit 45, and a transmission unit 46. The prediction unit 42 forms prediction information FI by predicting the future state of other regions based on broadcast-related information BI of different regions. The classification unit 44 assigns classification information CX related to the prediction information FI to the prediction information FI. The packaging unit 45 forms broadcast-related prediction information BFI by packaging the prediction information FI and the classification information CX. The transmission unit 46 transmits the broadcast-related prediction information BFI to the information distribution system 2 as provided information PI.

[0096] This configuration allows us to communicate predicted future conditions for other regions to individuals who have selected those regions as classification items C and D.

[0097] (3) The prediction unit 42 uses the trained model 50 to predict the future state of other regions. The trained model 50 is a prediction model formed based on a database of broadcast-related information BI for multiple regions. With this configuration, the chances of predictions being wrong when predicting future states can be reduced.

[0098] (4) Broadcast-related information BI and future status are disaster-related information. This configuration allows for prediction of future status in other regions regarding disaster-related information.

[0099] <Variation> The embodiments described above are illustrative of possible forms of the broadcasting system 1 and the broadcasting aggregation and analysis system 30, and are not intended to limit their forms. The broadcasting system 1 and the broadcasting aggregation and analysis system 30 may take forms different from those illustrated in the embodiments above. Examples include forms in which some of the configurations of the embodiments are replaced, modified, or omitted, or forms in which new configurations are added to the embodiments. Modifications of the embodiments are shown below.

[0100] (1) The method for assigning regional classification information CY to the announcement information AI is not limited to the example shown in the first embodiment. The following configurations may be added to the first embodiment, or may be used as alternatives to the method for assigning regional classification information CY in the first embodiment.

[0101] The broadcasting device 10 is installed within the broadcasting area. Therefore, the disaster announcements issued from the broadcasting device 10 are essentially information related to the region including the broadcasting area. Thus, in the broadcasting system 1, the regional classification information CY may be fixed. In a specific example, the memory unit 23 stores the unique regional classification information CR as classification information CX. The classification assignment unit 24 assigns the unique regional classification information CR as classification information CX to the announcement information AI.

[0102] The broadcasting device 10 may be equipped with a satellite positioning system to determine the location of the broadcasting device 10 itself. Examples of satellite positioning systems include GPS (Global Positioning System), QZSS (Quasi-Zenith Satellite System), and Galileo, which is operated by Europe. In this case, the broadcasting device 10 sets the location information acquired by the satellite positioning system into the unique regional classification information CR.

[0103] As shown in Figure 19, the broadcast-related information BI includes announcement information AI, unique regional classification information CR, and content classification information CZ. The data structure of the broadcast-related information BI is the same as that of the broadcast-related information BI in the first embodiment.

[0104] With this configuration, the regional classification information CY assigned to the announcement information AI is fixed to one. This eliminates the need to select a regional classification information CY. Furthermore, it reduces the likelihood of selecting the wrong regional classification information CY.

[0105] (2) The method for assigning regional classification information CY to the announcement information AI is not limited to the example shown in the first embodiment. The following configurations may be added to the first embodiment or may be used as alternatives to the method for assigning regional classification information CY in the first embodiment.

[0106] Refer to Figure 20 to illustrate another example of how to assign regional classification information (CY). During a disaster, disaster announcements always include the date, time, and location. Therefore, by analyzing disaster announcements, it is possible to estimate regional classification information CY related to the announcement information AI. For this reason, broadcasting system 1 may be modified as follows.

[0107] In the broadcasting system 1, the information transmission device 20 may have a regional analysis unit 60. The regional analysis unit 60 extracts regions related to the announcement information AI from the announcement information AI formed by the information formation unit 22. Based on the extracted regions, the regional analysis unit 60 identifies a regional classification information CY related to the announcement information AI from a plurality of regional classification information CYs. For example, if there is a region that is the same as the extracted region among the plurality of regional classification information CYs, the regional analysis unit 60 identifies that region as the regional classification information CY related to the announcement information AI. If there is no region that is the same as the extracted region among the plurality of regional classification information CYs, the regional analysis unit 60 notifies that no regional classification information CY related to the announcement information AI could be found. Then, the classification assignment unit 24 assigns the regional classification information CY identified by the regional analysis unit 60 to the announcement information AI. If no regional classification information CY related to the announcement information AI can be found, the first selection unit 27 assigns a regional classification information CY to the announcement information AI.

[0108] This configuration reduces the effort required to select regional classification information CY for the announcement information AI, as the regional analysis unit 60 identifies the regional classification information CY. This allows for continuous and uninterrupted information transmission when disaster announcements are made consecutively.

[0109] (3) The method for assigning content classification information CZ to the announcement information AI is not limited to the example shown in the first embodiment. The following configurations may be added to the first embodiment or may be used as alternatives to the method for assigning content classification information CZ.

[0110] Refer to Figure 21 to illustrate another example of how to assign content classification information (CZ). During a disaster, disaster announcements invariably include information related to the disaster. Therefore, by analyzing disaster announcements, it is possible to estimate content classification information CZ related to the announcement information AI. For these reasons, broadcasting system 1 may be modified as follows.

[0111] Therefore, in the broadcasting system 1, the information transmission device 20 may have a content analysis unit 70. The content analysis unit 70 analyzes the announcement content from the announcement information AI formed by the information formation unit 22. Through this analysis, the content analysis unit 70 identifies a content classification information CZ related to the announcement information AI from a plurality of content classification information CZs that are pre-registered as classification items CA. For example, if there is information with the same content as the content obtained by the analysis among the plurality of content classification information CZs, the content analysis unit 70 identifies that information as the content classification information CZ related to the announcement information AI. If there is no information with the same content as the content obtained by the analysis among the plurality of content classification information CZs, the content analysis unit 70 notifies that no content classification information CZ related to the announcement information AI could be found. The classification assignment unit 24 assigns the content classification information CZ identified by the content analysis unit 70 to the announcement information AI. If no content classification information CZ related to the announcement information AI is found, the second selection unit 28 assigns the content classification information CZ to the announcement information AI.

[0112] This configuration reduces the effort required to select content classification information CZs, as the content analysis unit 70 identifies content classification information CZs related to the announcement information AI. As a result, when disaster announcements are made continuously, information can be transmitted without interruption.

[0113] (4) The method for selecting the classification item CD is not limited to the example shown in the first embodiment. The following configurations may be added to the first embodiment or may be used as alternatives to the selection method in the first embodiment. In the first embodiment, the classification item CD is selected in advance from the classification item CA by a registered user of the information distribution system 2. The classification item CA includes the regional classification item CB and the content classification item CC. The regional classification item CB may be set as follows.

[0114] Registered users of Information Distribution System 2 may want to obtain information about areas other than those they have pre-selected. For example, a registered user may be affected by a disaster far from their home or living area. In such cases, the registered user will want to obtain information about that location. If they are outdoors, they can obtain their current location information through cell phone base stations or GPS location information. If they are indoors, they can obtain their current location information through beacons or other location information when emergency broadcasting equipment is in use. Therefore, the registered user may obtain their current location information and select the regional classification item CB for the area related to their current location, thereby receiving disaster-related information from Information Distribution System 2. Alternatively, the following configuration is also possible: If requested by a registered user, Information Distribution System 2 may set the regional classification item CB identified based on the current location information transmitted by the registered user as the registered user's selected classification item CD. This allows the registered user to urgently obtain information about the area including their current location.

[0115] (5) In each embodiment, the broadcasting system 1 may include a text input unit for inputting character information and a speech synthesis unit for synthesizing an audio signal based on the character information. In this case, the broadcasting system 1 transmits the synthesized audio signal to the loudspeaker 3. The broadcasting system 1 also forms broadcast-related information BI when character information is input to the text input unit and transmits the broadcast-related information BI as provided information PI to the information distribution system 2. Even with such a configuration, the effects similar to those of the first or second embodiment can be obtained.

[0116] (6) In each embodiment, the broadcasting system 1 may have a voice translation function. For example, the broadcasting system 1 may translate a Japanese announcement into English and then form an English announcement voice signal AS. The broadcasting system 1 may translate an English announcement into Japanese and then form a Japanese announcement voice signal AS.

[0117] (7) In each embodiment, the broadcasting system 1 may have a text translation function. For example, the broadcasting system 1 may translate Japanese text information into English and then form an English announcement voice signal AS or an English text information signal. Alternatively, the broadcasting system 1 may translate English text information into Japanese and then form a Japanese announcement voice signal AS or a Japanese text information signal.

[0118] With this configuration, disaster information or various other information regarding events occurring domestically can be transmitted to foreigners in Japan or overseas via the information distribution system 2. Furthermore, disaster information or various other information regarding events occurring overseas can be transmitted to Japanese citizens in Japan or overseas via the information distribution system 2.

[0119] (8) In the third embodiment, the broadcast-related information BI and future state may be information related to transportation. For example, the broadcast-related information BI may include the suspension and resumption of railway operations due to weather changes, as well as the suspension and resumption of operations of aircraft and ships. The broadcast-related information BI may also include the details and progress of accidents caused by weather changes, and the recovery status of malfunctions resulting from accidents. The prediction device 40 predicts the future state of other regions in adjacent regions based on the broadcast-related information BI of one region. With this configuration, it is possible to predict the future state of other regions with respect to transportation information from the broadcast-related information BI of one region.
