Description

[Technical Field]

[0001] The present invention relates to a receiving device, a reception processing method, a reception processing program, and a recording medium on which the reception processing program is recorded. [Background technology]

[0002] Receivers that receive broadcast content (digital broadcasts) including data broadcasts from broadcast stations and simultaneously display video based on the data broadcasts have become increasingly popular. Recently, practical application of broadcast-communication integrated systems that combine broadcasting and communications has begun. These broadcast-communication integrated systems are services in which a receiver receives not only broadcast content broadcast from broadcast stations but also communications content distributed by service providers via telecommunications lines such as the Internet, and plays the broadcast content and communications content in a coordinated manner. Such communications content includes information related to broadcast programs as well as information unrelated to broadcast programs, such as weather information and stock information.

[0003] With the practical application of broadcasting and communication cooperation systems, a technology has been proposed for displaying video based on data broadcasting or video based on communication content simultaneously with program video in digital broadcasting (see Patent Document 1: hereinafter referred to as "the conventional example"). In this conventional example technology, when video based on communication content is being displayed simultaneously with program video, if emergency or important information such as an emergency warning signal or an emergency earthquake alert is received through the broadcast content, the display of the video based on the communication content is forcibly stopped and the video of the emergency or important information included in the broadcast content is displayed instead.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-257227 Summary of the Invention [Problem to be solved by the invention]

[0005] In a broadcasting and communication integrated system, a user may intentionally display video based on communication content by, for example, pressing the "d" button on a remote control device (hereinafter also referred to as a "remote input device") to display video based on data broadcasting, and then selecting a menu from a menu included in the video to transition to video based on communication content. For this reason, the user may not be able to determine whether the video currently being displayed is based on communication content or data broadcasting.

[0006] In recent years, communication terminals such as smartphones and tablet devices have become widespread, and the mobile communication environment has been improved. With this improvement in the communication environment, when utilizing a broadcasting / communication integrated system, a configuration has been adopted in which a communication terminal wirelessly communicates with a mobile communication network to acquire communication content from a content server of a service provider and transmits the acquired communication content information to a receiving device. In mobile communications, in order to ensure that many users can communicate in a good environment, communication providers may impose usage restrictions (bandwidth restrictions) when the communication data volume exceeds a predetermined limit. The occurrence of such usage restrictions is undesirable because it makes it difficult to use the broadcasting / communication integrated system comfortably. Therefore, from the perspective of helping users avoid usage restrictions on mobile communications, it is important for users to recognize whether the currently displayed video is based on communication content or data broadcasting.

[0007] However, the above-mentioned conventional technology does not provide a measure to allow users to recognize the content source of the video displayed simultaneously with the program video in the broadcasting and communication integrated system. Therefore, when using communication content acquired by a communication terminal via a mobile communication network in the conventional technology, the user may suddenly find himself / herself subject to restrictions on the use of mobile communication.

[0008] Therefore, there is a need for a technology that can improve user convenience by letting users know whether the video currently being displayed is based on communication content when using a broadcasting and communication collaboration system. Meeting this need is one of the problems that the present invention aims to solve. [Means for solving the problem]

[0014] An embodiment of the present invention will now be described with reference to Figures 1 to 6. In the following description and drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant description will be omitted.

[0015] [composition] 1 is a block diagram showing a schematic configuration of a receiving device 100 according to an embodiment. In this embodiment, the receiving device 100 is installed in a vehicle, which is a moving object, and receives and processes terrestrial digital television broadcast waves. A communication terminal 210 is also installed in the vehicle and connected to the receiving device 100. The receiving device 100 then acquires and processes communication content distributed from a service provider via a telecommunications line via the communication terminal 210.

[0016] That is, the receiving device 100 is a device that implements a broadcasting and communication cooperation service that combines a broadcasting service and a communication service. The broadcasting and communication cooperation service is realized by executing applications transmitted from a broadcasting station and a service provider. The executed applications are classified into linked applications related to broadcast programs and non-linked applications not related to broadcast programs.

[0017] Here, the linked application is activated only while the linked broadcast program is being viewed, and is terminated when the linked broadcast program ends or when the linked broadcast program is changed to another broadcast program. The non-linked application can be activated and terminated at any time by the user. In this embodiment, the application of the broadcast / communication linked service is activated by the user pressing the "d" button on the remote input device.

[0018] The communication terminal 210 is, for example, a smartphone, and is capable of wirelessly communicating with a mobile communication network to access a communication content server of a service provider, etc. In this embodiment, a usage restriction contract is concluded between the user of the communication terminal 210 and the communication provider, and if the monthly communication data volume exceeds a predetermined data volume, the communication speed until the end of the month is slowed down.

[0019] The communication terminal 210 may be a communication terminal such as a tablet terminal, a PDA (Personal Digital Assistant), a mobile phone, or a personal computer.

[0020] <Configuration of Receiving Device 100> Next, the configuration of the above-mentioned receiving device 100 will be described.

[0021] 1, the receiving device 100 includes an antenna 110, an RF processing unit 120, an interface 130, and a playback processing unit 140. The receiving device 100 also includes an input unit 150, a sound output unit 160, a display unit 170, and a control unit 190.

[0022] The antenna 110 receives terrestrial digital television broadcast waves transmitted from a broadcast station. The signal RFS received by the antenna 110 is sent to the RF processing unit 120.

[0023] The RF processing unit 120 receives the received signal RFS sent from the antenna 110. Then, in accordance with a tuning command CSL sent from the control unit 190, the RF processing unit 120 performs tuning processing to extract a signal of a desired broadcast station to be tuned from the received signal RFS and converts it into an intermediate frequency signal IFD (hereinafter simply referred to as "signal IFD") having components in a predetermined intermediate frequency band. The signal IFD thus obtained is sent to the reproduction processing unit 140. Here, the signal IFD is a digital signal. The RF processing unit 120 performs part of the functions of a broadcast reception processing section.

[0024] The interface 130 is used when transmitting and receiving data between the receiving device 100 and the communication terminal 210. For example, a communication content signal received by the communication terminal 210 via a mobile communication network is sent to the playback processing unit 140 via the interface 130. The interface 130 also performs part of the function of a communication content acquisition unit.

[0025] Under the control of the control unit 190, the playback processing unit 140 processes the signal IFD sent from the RF processing unit 120 and the communication content signal sent from the interface 130 to generate video data IDT to be sent to the display unit 170. Also, under the control of the control unit 190, the playback processing unit 140 processes the signal IFD sent from the RF processing unit 120 to generate audio data ADT to be supplied to the sound output unit 160. The configuration of the playback processing unit 140 will be described in detail later.

[0026] The input unit 150 is configured by a key section provided on the main body of the receiving device 100 and / or a remote input device having a key section. Here, the key section provided on the main body can be a touch panel provided on the display device of the display unit 170. Also, instead of or in addition to a configuration having a key section, a configuration can be adopted in which input is made by voice using voice recognition technology.

[0027] In this embodiment, the input unit 150 is configured as a remote input device equipped with a key section.

[0028] The user operates the input unit 150 to set the operation details of the receiving device 100 and input operation commands. For example, the user uses the input unit 150 to input commands such as tuning in to a specific broadcasting station, and displaying video based on data broadcasting and video based on communication content. The input contents to the input unit 150 are sent to the control unit 190 as input data IPD. In other words, the input unit 150 functions as an operation unit. The method of issuing a command to display video based on data broadcasting and specifying the display of video based on communication content will be described later.

[0029] The sound output unit 160 is configured to include (i) a DA (Digital to Analogue) converter that converts the audio data ADT sent from the playback processing unit 140 into an analog signal, (ii) an amplifier that amplifies the analog signal output from the DA converter, and (iii) a speaker that converts the amplified analog signal into sound. The sound output unit 160 reproduces and outputs broadcast sound corresponding to the broadcast wave of the selected channel.

[0030] The display unit 170 includes, for example, (i) a display device such as a liquid crystal panel, an organic EL (Electro Luminescence) panel, or a PDP (Plasma Display Panel), and (ii) a display control circuit that causes the display device to display an image based on the video data IDT sent from the playback processing unit 140 and the communication information video data CDT sent from the control unit 190. Based on the video data IDT, the display unit 170 plays and displays program broadcast video corresponding to the selected channel, video based on data broadcasting, and video based on communication content.

[0031] Furthermore, the display unit 170 displays the communication information of the communication terminal 210 based on the communication information video data CDT and presents it to the user. The manner in which the communication information is presented will be described later. In this embodiment, the display device of the display unit 170 is mounted near the front panel inside the vehicle. The display unit 170 functions as part of the presentation unit and the display unit.

[0032] The control unit 190 performs various processes and controls the overall operation of the receiving device 100. The configuration of the control unit 190 will be described in detail later.

[0033] <Configuration of the playback processing unit 140> Next, the configuration of the reproduction processing unit 140 will be described.

[0034] 2, the playback processing unit 140 includes a demodulation unit 141, a decoding unit (demultiplexer unit) 142, an audio processing unit 143, a program video processing unit 144, and a data broadcast processing unit 145. The playback processing unit 140 also includes a communication input / output unit 146, a communication content processing unit 147, a communication management unit 148, and a display video creation unit 149.

[0035] The demodulation unit 141 receives the signal IFD sent from the RF processing unit 120. Then, the demodulation unit 141 performs OFDM (Orthogonal Frequency Division Multiplex) demodulation on the signal IFD. The signal demodulated in this manner is sent to the decoding unit 142 as a demodulated signal.

[0036] The decoding unit 142 receives the demodulated signal sent from the demodulation unit 141. Then, the decoding unit 142 performs decoding processing on the demodulated signal and sends the decoded result related to the audio to the audio processing unit 143 as decoded audio data. The decoding unit 142 also sends the decoded result related to the program video to the program video processing unit 144 as decoded program video data. Furthermore, the decoding unit 142 sends the decoded result related to the data broadcast to the data broadcast processing unit 145 as decoded data broadcast data. Note that a data broadcast application is also sent to the data broadcast processing unit 145.

[0037] Furthermore, the decoding unit 142 sends the decoding results other than audio, program video, and data broadcasting as a signal DBD to the control unit 190. Information included in this signal DBD includes an application information table, application files, etc. This application information table includes the application name, application ID, control information for controlling the start and end of the application, location information of the server for distributing the application file, information for identifying the application file, etc.

[0038] The audio processing unit 143 generates audio data ADT based on the decoded audio data. The generated audio data ADT is sent to the sound output unit 160.

[0039] The program video processing unit 144 generates program video data based on the decoded program video data. The generated program video data is sent to the display video creation unit 149. The program video processing unit 144 performs part of the function of the broadcast reception processing unit.

[0040] The data broadcast processing unit 145 executes a data broadcast application under the control of the control unit 190, and generates data broadcast video data based on the decoded data broadcast data. The generated data broadcast video data is sent to the display video creation unit 149. The data broadcast processing unit 145 performs part of the function of the broadcast reception processing unit.

[0041] The communication input / output unit 146 inputs and outputs data through communication via the interface 130, the communication terminal 210, and the mobile communication network under the control of the control unit 190. For example, when the communication input / output unit 146 acquires an application information table or an application file transmitted from a service provider, the communication input / output unit 146 sends the application information table or the application file to the control unit 190.

[0042] Furthermore, the communication input / output unit 146 controls the communication terminal 210 in accordance with instructions from an application executed by the control unit 190, and receives communication content data distributed from a communication content server of a service provider. Then, the communication input / output unit 146 sends the received communication content data to the communication content processing unit 147. The communication input / output unit 146 performs part of the function of a communication content acquisition unit.

[0043] The communication content processing unit 147 decodes the communication content data sent from the communication input / output unit 146 under the control of the control unit 190, and generates communication content video data. The generated communication content video data is sent to the display video creation unit 149.

[0044] The communication management unit 148 has a built-in calendar mechanism, and derives and acquires the cumulative value of the communication data volume for the current month by the communication terminal 210. The communication management unit 148 then sequentially sends the cumulative value of the communication data volume to the control unit 190 as communication volume information CMI. In this embodiment, the cumulative value of the communication data volume is reset to zero at the beginning of the month or on a date designated by the user under the control of the control unit 190. The communication management unit 148 functions as a communication volume acquisition unit.

[0045] The display video creation unit 149 receives the program video data sent from the program video processing unit 144 and the data broadcast video data sent from the data broadcast processing unit 145. The display video creation unit 149 also receives the communication content video data sent from the communication content processing unit 147. Then, the display video creation unit 149 creates video data IDT in accordance with the video creation command ICC sent from the control unit 190. Subsequently, the display video creation unit 149 sends the created video data IDT to the display unit 170.

[0046] Configuration of control unit 190 Next, the configuration of the control unit 190 will be described.

[0047] As shown in FIG. 3, the control unit 190 includes a channel selection processing unit 191, a broadcasting and communication cooperation service execution unit 192, and a presentation processing unit 193.

[0048] When the content of the input data IPD sent from the input unit 150 is a channel selection specification, the channel selection processing unit 191 generates a channel selection command CSL corresponding to the specified desired broadcast station. Then, the channel selection processing unit 191 sends the generated channel selection command CSL to the RF processing unit 120.

[0049] When the content of the input data IPD sent from the input unit 150 specifies the display of video based on data broadcasting, the broadcasting and communication cooperation service execution unit 192 generates a data broadcasting processing command DEC and sends it to the data broadcasting processing unit 145, and also generates a video creation command ICC to display the program video and the video based on data broadcasting simultaneously and sends it to the display video creation unit 149.

[0050] Furthermore, when the content of the input data IPD sent from the input unit 150 specifies the display of video based on the communication content, or when the application is automatically started, the broadcasting and communication cooperation service execution unit 192 executes the application of the broadcasting and communication cooperation service. When the application is executed, the broadcasting and communication cooperation service execution unit 192 sends a command to the communication input / output unit 146 to receive communication content data from the communication content server in accordance with the application being executed, and generates a communication content processing command CEC to process the received communication content data and sends it to the communication content processing unit 147. Furthermore, the broadcasting and communication cooperation service execution unit 192 generates a video creation command ICC to simultaneously display the program video and the video based on the communication content in accordance with the application being executed, and sends it to the display video creation unit 149.

[0051] In this embodiment, when the user presses the "d" button on the remote input device, the home screen of the broadcasting and communication cooperation service is displayed on the display unit 170. Various menus are displayed on this home screen. When the user selects data broadcasting from the menu on the home screen of the broadcasting and communication related service, video based on the data broadcasting is displayed on the display unit 170. When the user selects a communication content menu from the menu on the home screen of the broadcasting and communication related service, video based on the selected communication content is displayed on the display unit 170. For this reason, in this embodiment, the operation of specifying the display of video based on communication content is the same as the operation of specifying the display of video based on data broadcasting.

[0052] Furthermore, during a period in which the program video and the video based on the communication content are being displayed simultaneously, the broadcasting and communication cooperation service execution unit 192 sends display information indicating that the communication video is being displayed to the presentation processing unit 193. During a period in which the video based on the communication content is not being displayed simultaneously, the broadcasting and communication cooperation service execution unit 192 sends display information indicating that the communication video is not being displayed to the presentation processing unit 193.

[0053] That is, the broadcast communication cooperative service execution unit 192 functions as a command acquisition unit and a display control unit. A display command for a video based on data broadcasting corresponds to the first command, and a display command for a video based on communication content corresponds to the second command.

[0054] The presentation processing unit 193 receives the communication volume information CMI sent from the communication management unit 148. Then, the presentation processing unit 193 generates information video data based on the cumulative communication data volume of the communication terminal 210 from the beginning of the month to the present, based on the communication volume information CMI.

[0055] Furthermore, when the content of the display information sent from the broadcast communication cooperative service execution unit 192 indicates that a communication video is being displayed, the presentation processing unit 193 generates the information video data and also generates icon video data indicating that a video based on the communication content is currently being displayed on the display unit 170. Then, the presentation processing unit 193 generates communication information video data CDT based on the information video data and the icon video data and sends it to the display unit 170.

[0056] Furthermore, when the content of the display information sent from the broadcast communication cooperative service execution unit 192 indicates that communication video is not being displayed, the presentation processing unit 193 generates information video data and also generates icon video data indicating that video based on the communication content is not currently being displayed on the display unit 170. Then, the presentation processing unit 193 generates communication information video data CDT based on the information video data and the icon video data and sends it to the display unit 170.

[0057] Here, the presentation processing unit 193 performs part of the function of the presentation unit.

[0058] [Operation] The operation of the receiving device 100 configured as above will be described, focusing mainly on the presentation control process of communication-related information by the control unit 190.

[0059] The presentation control process of communication-related information starts when the power of the receiving device 100 is turned on and the user performs a tuning command specifying a desired broadcast station using the input unit 150. When the tuning command specifying the desired broadcast station is input to the input unit 150 in this manner, the tuning processing unit 191 of the control unit 190 generates a tuning command CSL corresponding to the desired broadcast station and sends it to the RF processing unit 120 (see FIGS. 1 and 3).

[0060] Upon receiving the tuning command CSL, the RF processing unit 120 performs tuning processing to extract a signal of the desired broadcast station from the received signal RFS and converts it into a signal IFD having components in a predetermined intermediate frequency band.Then, the RF processing unit 120 sends the signal IFD to the reproduction processing unit 140 (see FIG. 1).

[0061] In the playback processing unit 140, the demodulation unit 141 demodulates the signal IFD sent from the RF processing unit 120 to generate a demodulated signal. The demodulation unit 141 then sends the generated demodulated signal to the decoding unit 142. The decoding unit 142 then decodes the demodulated signal sent from the demodulation unit 141 to generate decoded audio data and send it to the audio processing unit 143, and also generates decoded program video data and send it to the program video processing unit 144 (see FIG. 2). The decoding unit 142 also generates decoded data broadcast data and sends it to the data broadcast processing unit 145, and separates the application information table and the like from the demodulated signal and sends it to the broadcasting and communication cooperative service execution unit 192 of the control unit 190 (see FIGS. 2 and 3).

[0062] Subsequently, the audio processing unit 143 processes the decoded audio data to generate audio data ADT and sends it to the sound output unit 160. Furthermore, the program video processing unit 144 generates decoded program video data and sends it to the display video creation unit 149. Then, under the control of the control unit 190, the display video creation unit 149 sends the decoded program video data as video data IDT to the display unit 170 (see FIG. 2).

[0063] Furthermore, when the presentation control process is started, the communication management section 148 of the playback processing unit 140 sequentially sends the cumulative value of the communication data volume of the communication terminal 210 for the current month to the presentation processing section 193 of the control unit 190 as communication volume information CMI.

[0064] 4, first, in step S11, the broadcasting and communication cooperative service execution unit 192 of the control unit 190 determines whether or not a video based on communication content is being displayed on the display unit 170. If the result of this determination is negative (step S11: N), the process proceeds to step S12.

[0065] In step S12, the broadcast communication cooperative service execution unit 192 sends display information indicating that communication video is not being displayed to the presentation processing unit 193. Subsequently, in step S13, the presentation processing unit 193 generates icon video data indicating that video based on communication content is not being displayed on the display unit 170. Then, the presentation processing unit 193 generates communication information video data CDT from the icon video data and information video data of the current cumulative communication data volume of the communication terminal 210 for the current month, and sends the communication information video data CDT to the display unit 170. After that, the process returns to step S11.

[0066] On the other hand, if the result of the determination in step S11 is affirmative (step S11: Y), the process proceeds to step S14. In this step S14, the broadcast communication cooperation service execution unit 192 sends display information indicating that communication video is being displayed to the presentation processing unit 193. Thereafter, the process proceeds to step S15.

[0067] In step S15, the presentation processing unit 193 generates icon image data indicating that an image based on the communication content is being displayed on the display unit 170. Then, the presentation processing unit 193 generates communication information image data CDT from the icon image data and information image data of the current cumulative communication data volume of the communication terminal 210 for the current month, and sends the communication information image data CDT to the display unit 170. After that, the process returns to step S11.

[0068] Thereafter, the processes of steps S11 to S15 are repeated to perform the display control process of the breaking news information.

[0069] <Example of display of presentation information on the display unit 170> 5 shows an example of a display that is displayed on display unit 170 when the result of the determination in step S11 is negative. Here, only the program video is displayed in area 171 of display unit 170, and the communication information video is displayed in area 172. Note that the "◯" shown in area 172 is an icon indicating that the communication video is not being displayed.

[0070] 6 shows an example of a display that is displayed on the display unit 170 when the result of the determination in step S11 is affirmative. Here, an example is shown in which a weather information image based on communication content is displayed simultaneously with a program image in an area 171 of the display unit 170. Then, a communication information image is displayed in an area 172 of the display unit 170, and the "●" shown in the area 172 is an icon indicating that a communication image is being displayed.

[0071] As described above, in this embodiment, the broadcast / communication cooperative service execution unit 192 of the control unit 190 determines whether or not video based on the communication content is being displayed on the display unit 170. When it is determined that video based on the communication content is being displayed on the display unit 170, the broadcast / communication cooperative service execution unit 192 sends display information indicating that the communication video is being displayed to the presentation processing unit 193. Upon receiving the display information, the presentation processing unit 193 generates communication information video data CDT indicating that video based on the communication content is being displayed on the display unit 170, and sends the generated data to the display unit 170.

[0072] On the other hand, when it is determined that the video based on the communication content is not being displayed on the display unit 170, the broadcast / communication cooperative service execution unit 192 sends display information indicating that the communication video is not being displayed to the presentation processing unit 193. Then, the presentation processing unit 193 generates communication information video data CDT indicating that the video based on the communication content is not being displayed on the display unit 170, and sends it to the display unit 170.

[0073] Therefore, when the display specification of the video based on the communication content is the same as the operation of the display specification of the video based on the data broadcasting, the user can be made to recognize whether the video currently being displayed is based on the communication content.

[0074] Furthermore, in this embodiment, the cumulative communication data volume from the beginning of the month to the present of the communication terminal 210 is presented to the user regardless of whether or not a video based on the communication content is being displayed on the display unit 170. This makes it possible to provide the user with information for avoiding restrictions on the use of mobile communication, thereby improving user convenience.

[0075] Therefore, according to this embodiment, when using the broadcasting and communication integration system, the user can be made aware of whether the currently displayed video is based on communication content, thereby improving user convenience.

[0076] [Modification of the embodiment] The present invention is not limited to the above-described embodiment, and various modifications are possible.

[0077] For example, in the above embodiment, when an image based on the communication content is displayed on the display unit, a "●" icon is displayed, and when an image based on the communication content is not displayed on the display unit, a "○" icon is displayed. However, when the communication terminal is communicating, the fact that communication is in progress may be indicated by another display mode, such as by flashing the icon.

[0078] In the above embodiment, the current cumulative communication data volume of the communication terminal is presented to the user, but the receiving device may acquire a usage limit value in advance and present the cumulative communication data volume together with the limit value to the user. In this case, convenience can be improved when the user is not aware of the usage limit value.

[0079] In the above embodiment, when a user presses the "d" button on a remote input device, the home screen of the broadcasting and communication cooperation service is launched, and when the user selects data broadcasting from the menu on the home screen, video based on the data broadcasting is displayed, and when the user selects a menu of communication content, video based on the selected communication content is displayed. However, video based on data broadcasting and video based on communication content may be displayed using other operation modes. It looks like this.

[0080] In addition, in the above embodiment, the content of the usage restriction on the communication terminal was that if the monthly communication data volume exceeds a predetermined data volume, the communication speed will be slowed down until the end of the month, but other types of usage restrictions may also be used.

[0081] In the above embodiment, the presentation processing unit sends the generated communication information video data to the display unit, but it may send the data to the display video creation unit. In this case, the display video creation unit creates video data to be sent to the display unit based on the program video data, data broadcast video data, communication content video data, and the communication information video data sent from the presentation processing unit.

[0082] Furthermore, in the above embodiment, the present invention is applied to a receiving device mounted on a vehicle, but the present invention can also be applied to a receiving device installed on a moving object other than a vehicle, or to a receiving device installed in a home.

[0083] Note that the functions of the control unit in the above-described embodiments may be realized by configuring a part or all of the control unit as a computing means including a central processing unit (CPU) or the like, and executing a pre-prepared program on the computer. This program is recorded on a computer-readable recording medium such as a hard disk, CD-ROM, or DVD, and is read from the recording medium and executed by the computer. The program may also be obtained in the form of being recorded on a portable recording medium such as a CD-ROM or DVD, or may be obtained in the form of distribution via a network such as the Internet.
