This is displayed on the part 319. Note that “SHV” is an abbreviation for Super Hi-Vision and means high-resolution broadcasting. As described above, the receiving device 31 according to the first embodiment does not present the viewer with broadcast switching means for high-resolution broadcasting in an environment where high-resolution broadcasting cannot be received. That is, the receiving device 31 switches whether to display broadcast switching means for high-resolution broadcasting based on the result of determining whether or not high-resolution broadcasting can be received.
Hereinafter, the first embodiment will be described in detail.

(Broadcast system configuration)
FIG. 2 is a schematic diagram showing an example of the configuration of the broadcasting system according to the first embodiment of the present invention.
The broadcast system 1 according to the first embodiment includes a transmission device 11, a broadcast transmission path 12, and a reception device 31. In the broadcasting system 1, the number of the transmission apparatuses 11 and the reception apparatuses 31 is generally plural. However, in the following description, in order to facilitate the description, the transmission apparatuses 11 and the reception apparatuses 31 are different. The case of the broadcasting system 1 in which the number is one each will be described.

  Further, in the following description, a case will be described in which, for example, an MMT (MPEG Media Transport) system (for example, see Non-Patent Document 1) is adopted as a media transport system for digital broadcasting in the broadcasting system 1.

  The transmission device 11 constitutes broadcasting equipment possessed by a broadcaster or the like. For example, the transmission device 11 is a radio wave transmission base station for a broadcaster or the like to transmit a broadcast wave. The transmission device 11 sequentially transmits program data and configuration information indicating the content of the broadcast program to the reception device 31 via the broadcast transmission path 12. The program data includes video data and audio data. However, the program data may not include audio data. The configuration information is information that defines the components of a broadcast program and the components of a service provided by broadcasting.

  The broadcast transmission path 12 is a transmission path for transmitting various data transmitted by the transmission apparatus 11 to a large number of reception apparatuses 31 simultaneously. The broadcast transmission path 12 may be a predetermined frequency relayed by the broadcast satellite 13 or the radio tower 14, for example. Note that a part of the broadcast transmission path 12 may include a communication line.

  The reception device 31 receives broadcast waves from the transmission device 11 via the broadcast transmission path 12. The receiving device 31 acquires program data and configuration information transmitted by broadcast waves. The receiving device 31 acquires video data and audio data from the program data. The receiving device 31 displays the video indicated by the acquired video data. In addition, the receiving device 31 reproduces the voice (voice or music sound) indicated by the acquired voice data.

  In this example, the receiving device 31 is a television receiver. However, the receiving device 31 is other equipment (for example, a portable information terminal, a personal computer, etc.) capable of receiving the program data and configuration information transmitted by the transmitting device 11 via the broadcast transmission path 12. There may be.

(Configuration of transmitter)
Next, the configuration of the transmission device 11 will be described.
FIG. 3 is a block diagram showing an example of the configuration of the transmission device 11 according to the first embodiment of the present invention.
The transmission apparatus 11 includes a program data acquisition unit 111, a configuration information acquisition unit 113, a multiplexing unit 114, an encryption unit 115, and a transmission unit 116.

The program data acquisition unit 111 acquires video data and audio data constituting a broadcast program.
The program data acquisition unit 111 acquires video data encoded by a predetermined video encoding method. For example, the predetermined video coding method is ISO / IEC 23008 HEVC (International Organization for Standardization / International Electrical Commission 230308 Part2 High Efficient Video Coding), which is also simply referred to as H coding code.

  The program data acquisition unit 111 acquires audio data encoded by a predetermined audio encoding method. For example, the predetermined audio encoding method is an audio encoding method defined by ISO / IEC 14496 Part 3 (also simply referred to as MPEG-4 audio. Note that MPEG is an abbreviation for Moving Picture Experts Group). is there.

  The program data acquisition unit 111 generates program data in a predetermined format from the acquired video data and audio data. The program data acquisition unit 111 outputs the generated program data to the multiplexing unit 114. For example, the program data in a predetermined format is an MPU (Media Processing Unit) defined by ISO / IEC 23008 Part1 MMT (MPEG Media Transport, also simply referred to as MMT). Each MPU includes video data or audio data of a unit that can perform video and audio decoding processing.

The configuration information acquisition unit 113 acquires configuration information. The configuration information is information that defines the components of a broadcast program and the components of a service provided by broadcasting as described above.
For example, the configuration information includes TLV-SI (Type Length Value-System Information) and MMT-SI (MMT-System Information).
TLV-SI is control information relating to multiplexing of IP packets, and provides information for channel selection and correspondence information between IP addresses and services. MMT-SI is control information indicating the configuration of a broadcast program.

  The TLV-SI includes a TLV-NIT (TLV-Network Information Table; TLV network information table) and an AMT (Address Map Table) table. TLV-NIT represents information about the physical configuration of the TLV stream carried by the network and the characteristics of the network itself. AMT provides information that associates a service identifier that identifies a broadcast program number with an IP packet.

  For example, the configuration information includes PSI (Program Specific Information). In addition, the PSI includes a network information table (NIT) and the like.

  The above TLV-SI, MMT-SI, TLV-NIT, AMT, and NIT are based on ARIB (Association of Radio Industries and Businesses), Non-Patent Document 1, Non-Patent Document 2, etc. This is the standard specified in.

  The configuration information acquisition unit 113 outputs the acquired configuration information to the multiplexing unit 114.

  The multiplexing unit 114 multiplexes the program data input from the program data acquisition unit 111 and the configuration information input from the configuration information acquisition unit 113 to generate multiplexed data in a predetermined format. For example, the multiplexed data in a predetermined format is a TLV (Type Length Value) packet. The multiplexing unit 114 outputs the generated multiplexed data to the encryption unit 115.

  The encryption unit 115 encrypts the multiplexed data input from the multiplexing unit 114 using a predetermined encryption method. For example, the predetermined encryption method is AES (Advanced Encryption Standard) or MULTI2. The encryption unit 115 outputs the encrypted multiplexed data to the transmission unit 116.

  The transmission unit 116 transmits the multiplexed data input from the encryption unit 115 to the reception device 31 via the broadcast transmission path 12. Here, the transmission unit 116 modulates a carrier wave having a predetermined carrier frequency with multiplexed data that is a baseband signal. Transmitter 116 radiates a radio wave (broadcast wave) in a channel band corresponding to the carrier frequency through an antenna (not shown).

(Receiver configuration)
Next, the configuration of the receiving device 31 will be described.
FIG. 4 is a block diagram showing an example of the configuration of the receiving device 31 according to the first embodiment of the present invention.

  The receiving device 31 includes a receiving unit 311, a decoding unit 312, a separation unit 313, an audio decoding unit 314, a reproduction unit 316, a video decoding unit 317, a video synthesis unit 318, a display unit 319, a storage unit 322, an operation input unit 323, and A control unit 331 is included.

  The receiving unit 311 (tuner) receives the broadcast wave transmitted from the transmission device 11 through an antenna (not shown) via the broadcast transmission path 12. The receiving unit 311 converts the received received signal into multiplexed data by down-converting the received signal into a baseband signal at the frequency of the channel specified by the channel selection signal input from the control unit 331. The receiving unit 311 outputs the converted multiplexed data to the decoding unit 312.

  The decryption unit 312 decrypts the multiplexed data (encrypted) input from the reception unit 311 with a decryption method (for example, AES) corresponding to the method used by the encryption unit 115 of the transmission device 11. The decoded multiplexed data is generated. The decoding unit 312 outputs the generated multiplexed data to the separation unit 313.

  The separation unit 313 separates the decoded data input from the decoding unit 312 into program data and configuration information. Further, the separation unit 313 extracts video data and audio data from the program data. The separation unit 313 outputs the extracted video data to the video decoding unit 317. Further, the separation unit 313 outputs the extracted audio data to the audio decoding unit 314. Further, the separation unit 313 outputs the configuration information to the control unit 331.

The audio decoding unit 314 acquires audio data from the separation unit 313. The audio decoding unit 314 decodes the acquired audio data. Decoding is performed by a decoding method corresponding to the encoding method used for encoding. Thereby, the voice decoding unit 314 generates original voice data. The decoded audio data is data indicating the audio level at each time. For example, the encoding method used for encoding is MPEG-4 audio.
The audio decoding unit 314 outputs the decoded audio data to the reproduction unit 316.
The reproduction unit 316 reproduces audio based on the audio data input from the audio decoding unit 314. For example, the playback unit 316 includes a speaker.

The video decoding unit 317 acquires video data from the separation unit 313. The video decoding unit 317 decodes the acquired video data. Decoding is performed by a decoding method corresponding to the encoding method used for encoding. Thereby, the video decoding unit 317 generates original video data. The decoded video data is data indicating signal values forming a video (frame image) at each time. For example, encoding methods used for encoding are HEVC and MPEG-2 video.
The video decoding unit 317 outputs the decoded video data to the video synthesis unit 318.

The video synthesis unit 318 acquires video data from the video decoding unit 317. In addition, the video composition unit 318 acquires notification image data indicating a broadcast selection screen or the like from the control unit 331. For example, the video composition unit 318 generates a video in which a video such as a broadcast selection screen based on the notification image data is superimposed on a video based on the video data.
The video composition unit 318 outputs video data based on the generated video to the display unit 319.

The display unit 319 displays a video based on the video data acquired from the video composition unit 318.
For example, the display unit 319 includes a liquid crystal display, an organic EL (Electroluminescence) display, and the like.

The storage unit 322 is a storage medium that stores various data and programs.
For example, the storage unit 322 stores data indicating information related to broadcasting that can be received by the receiving device 31 of itself. Receivable broadcasts include, for example, terrestrial digital broadcasts, satellite digital broadcasts (BS, CS), and high resolution broadcasts (4K broadcasts, 8K broadcasts).

  For example, the storage unit 322 includes an HDD (Hard Disk Drive), a flash memory, an EEPROM (Electrically Erasable Programmable Read Only Memory), a ROM (Read Only Memory / Read Only Memory), and a RAM (Random Read / Write Memory). Memory), or any combination thereof.

The operation input unit 323 receives an operation input by a user of the receiving device 31. The operation input unit 323 generates an operation signal generated based on the received operation input. The operation input unit 323 outputs the generated operation signal to the control unit 331.
For example, the operation signal generated by the operation input unit 323 is a signal indicating power on / off, a signal indicating a broadcast wave channel, and the like. In this example, the operation input unit 323 is an input interface that receives an operation signal from a remote controller (hereinafter referred to as a remote controller). However, the operation input unit 323 may be an input interface that receives an operation signal from, for example, an operation button included in its own receiving device 31 or a portable information terminal (for example, a smartphone).

The control unit 331 includes a computer (CPU). The control unit 331 executes software (program) stored in the storage unit. Thereby, the control unit 331 controls various operations of the receiving device 31.
For example, the control unit 331 acquires configuration information from the separation unit 313. The control unit 331 extracts NIT (network information table), TLV-NIT, or the like for determining that the broadcast is receivable from the acquired configuration information.

  In the first embodiment, at the time of initial setting of the receiving device 31, various types of broadcast waves are received. For example, when the receiving device 31 (for example, a television receiver) is installed, the initial setting of the receiving device 31 is performed by an installer or the like. In the initial setting, for example, the receiving device 31 performs channel scan of each broadcast wave. Here, when the receiving device 31 receives a broadcast wave of a satellite digital broadcast of 4K video, and the control unit 331 acquires data indicating configuration information included in the broadcast wave, the control unit 331 is a satellite of 4K video. It is determined that digital broadcasting can be received.

Based on the acquisition of the configuration information, the determination unit 3311 determines that a broadcast wave including the acquired configuration information, that is, a broadcast corresponding to the acquired configuration information can be received. For example, the determination unit 3311 determines that its receiving device 31 can receive the high-resolution broadcast based on the acquisition of the configuration information corresponding to the high-resolution broadcast.
The determination unit 3311 stores the determination result in the storage unit 322.

  In addition, the determination unit 3311 outputs a signal indicating that it is determined that the broadcast corresponding to the acquired configuration information can be received to the notification unit 3313 or the switching unit 3312. For example, the determination unit 3311 outputs to the notification unit 3313 or the switching unit 3312 a signal indicating that the reception device 31 has determined that it can receive a high-resolution broadcast.

The notification unit 3313 acquires image data indicating a notification image corresponding to the acquired signal from the storage unit 322. The notification unit 3313 outputs the acquired image data to the video composition unit 318. The notification image is, for example, the broadcast selection screen s1 or the broadcast selection screen s2 shown in FIG.

  That is, for example, the notification unit 3313 obtains a signal indicating that the receiving device 31 has determined that the high-resolution broadcast can be received from the determination unit 3311. The notification unit 3313 displays a broadcast selection screen (for example, the broadcast selection screen s2 illustrated in FIG. 1B) that includes the high-resolution broadcast in the options based on the signal indicating that the high-resolution broadcast can be received. The image data shown is acquired from the storage unit 322. Then, the notification unit 3313 outputs the acquired image data to the video composition unit 318.
