Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(Receiver configuration)
FIG. 1 is a block diagram illustrating a schematic configuration of a receiving apparatus 10 according to the present embodiment.
The receiving apparatus 10 includes a receiving unit 101, a decoding unit 102, a separation unit 103, an SI analysis unit 104, a decoding unit 105, an output control unit 106, a display unit 107, a speaker 108, a communication IF (interface). ) 110, a memory 111, an external IF control unit 120, and a system control unit 130. In addition, the decoding unit 105 includes a video decoding unit 1051 and an audio decoding unit 1052. The receiving unit 101 receives a broadcast wave of a digital broadcast in which program data including video content (video information) is multiplexed. The content is a data group that constitutes a content that is distributed through two-way communication that is used together with a data broadcast program or a data broadcast program. In particular, when distributed by broadcasting, it refers to a set of streams in a program that distributes the data group. One data broadcast program can be composed of a plurality of contents. The program data includes video data and audio data of the program. The communication IF 110 is communicatively connected to a network. Digital broadcasting may be advanced BS broadcasting or current broadcasting (satellite / terrestrial digital broadcasting).

  For example, as a media transport system of digital broadcasting, ARIB (Association of Radio Industries and Businesses) The MMT (MPEG Media Transport) system described in the STD-60 standard is adopted explain. In advanced BS broadcasting, multiplexed data such as program data and configuration information is transmitted in the form of MMTP (MMT Protocol) packets. The configuration information is information for configuring a broadcast program and a service provided along with the broadcast, and includes control information such as MMT-SI (MMT-System Information) and TLV (Type Length Value) -SI. The MMT-SI is described by a message, a table, and a descriptor set by a broadcaster described later. TLV-SI is control information related to multiplexing of IP packets, and provides information for channel selection and correspondence information between IP addresses and services. In the current broadcast, for example, multiplexed data such as program data and configuration information is TS packetized and transmitted by TS (Transport Stream) defined in MPEG-2 SYSTEM, for example. These are the same when communication is used.

  In this embodiment, at least a part of a broadcast service that provides digital broadcasting (hereinafter also simply referred to as “service”) performs simultaneous broadcasting on at least a part of a broadcast program. Simultaneous broadcasting refers to simultaneous parallel broadcasting (for example, simultaneous parallel broadcasting of 2K broadcasting and 4K or 8K broadcasting) in which the same program is broadcast at a plurality of different resolutions in the same time zone. Note that 2K broadcast, 4K broadcast, and 8K broadcast are broadcasts of 2K video, 4K video, and 8K video content, respectively. Note that 2K video, 4K video, and 8K video are expressions based on the number of pixels in the horizontal direction of the video.

  The receiving unit 101 receives a broadcast wave of a digital broadcast to be transmitted by the antenna 11. In addition, the receiving unit 101 converts the 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 system control unit 130 and demodulating it. . Then, receiving section 101 outputs the converted multiplexed data to decoding section 102.

  The decryption unit 102 decrypts the multiplexed data (encrypted) input from the reception unit 101 using a decryption method (for example, AES (Advanced Encryption Standard) or MULTI2) corresponding to the method used on the transmission side. Then, the decoded multiplexed data is generated. Then, the decoding unit 102 outputs the generated multiplexed data to the separation unit 103.

  The separation unit 103 separates the decoded data input from the decoding unit 102 into program data and configuration information. Further, the separation unit 103 extracts video data and audio data from the program data. The separation unit 103 outputs the extracted video data to the video decoding unit 1051. Further, the separation unit 103 outputs the extracted audio data to the audio decoding unit 1052. Further, the separation unit 103 outputs the configuration information to the SI analysis unit 104.

  The SI analysis unit 104 analyzes control information such as MMT-SI and TLV-SI included in the configuration information. For example, the SI analysis unit 104 analyzes additional information (for example, “maximum resolution information”) regarding the resolution for each service based on information described in the MMT-SI, and uses the maximum resolution information for each service as an analysis result. Output to the system control unit 130. The maximum resolution information is information indicating the maximum resolution of the video content of the program broadcast by the service. A specific example of obtaining the maximum resolution information from the MMT-SI will be described later.

  Video data is input from the separation unit 103 to the video decoding unit 1051. The input video data is data encoded by a predetermined video encoding method (for example, HEVC, MPEG-2 video). The video decoding unit 1051 decodes the input video data using a decoding method corresponding to the encoding method used for encoding, and generates decoded video data. Then, the video decoding unit 1051 outputs the generated video data to the output control unit 106.

  The audio decoding unit 1052 receives audio data from the separation unit 103. The input audio data is data encoded by a predetermined audio encoding method (for example, MPEG-4 audio). The audio decoding unit 1052 decodes the input audio data using a decoding method corresponding to the encoding method used for encoding, and generates decoded audio data. Then, the audio decoding unit 1052 outputs the decoded audio data to the output control unit 106.

  The output control unit 106 outputs a video signal based on the video data input from the video decoding unit 1051 to the display unit 107. The display unit 107 displays a video based on the video data input from the video decoding unit 1051. For example, the display unit 107 includes a liquid crystal display, an organic EL (Electroluminescence) display, and the like. Further, the output control unit 106 outputs an audio signal based on the audio data input from the audio decoding unit 1052 to the speaker 108.

  The memory 111 is a storage medium that stores various data and programs. For example, the memory 111 includes an HDD (Hard Disk Drive), flash memory, EEPROM (Electrically Erasable Programmable Read Only Memory), ROM (Read Only Memory / Read Only Memory), and RAM (Random Access Memory). ), Or any combination thereof.

  The external IF control unit 120 performs an interface with an external device. For example, the external IF control unit 120 acquires a control signal from the remote controller 20. The remote controller 20 is a remote controller (remote operation device) for remotely operating the reception device 10, and transmits a control signal including operation information to the reception device 10 in accordance with a user operation. The external IF control unit 120 outputs operation information included in the acquired control signal to the system control unit 130.

The system control unit 130 includes a CPU and the like, and controls various operations of the reception device 10 by executing software (programs) stored in the memory 111.
FIG. 2 is a diagram illustrating an example of a functional configuration of the system control unit 130 according to the present embodiment. The system control unit 130 includes an extraction unit 131, an operation information acquisition unit 132, a channel selection unit 133, and a display control unit 134.

  The extraction unit 131 extracts information about resolution added for each of a plurality of services. For example, the extraction unit 131 acquires maximum resolution information for each service based on the analysis result input from the SI analysis unit 104 to the system control unit 130. Hereinafter, an example of how the SI analysis unit 104 obtains the maximum resolution information from the MMT-SI will be specifically described with reference to FIGS.

  The MMT-SI includes a message, a table, and a descriptor. Messages store tables and descriptors. The table has specific information attributes. The descriptor indicates more detailed information of the table. These messages, tables, and descriptors have a three-layer structure. The message includes a Package Access (PA) message, an M2 section message, a CA message, an M2 short section message, a data transmission message, and a message set by the operator.

  FIG. 3 is a diagram illustrating a configuration example of MMT-SI. The M2 section message included in the MMT-SI includes MH-BIT (MH-Broadcaster Information Table). The MH-BIT is a table used for presenting broadcaster information existing on the network. This MH-BIT includes an MH-service list descriptor.

  FIG. 4 is a diagram illustrating an example of the MH-service list descriptor. As shown in the figure, the MH-Service List Descriptor (MH-Service_List_Descriptor) includes a descriptor tag (descriptor_tag), a descriptor length (descriptor_length), a service identification (service_id), a service type (service_type), and the like. The service identification is a 16-bit field that uniquely identifies an information service in the TLV stream. The service format type is an 8-bit field and indicates the type of service according to the table shown in FIG.

  FIG. 5 is a diagram illustrating an example of the service format type. Meanings are defined for each service format type represented by 0x00 to 0xFF. For example, 0xA2 to 0xA3, 0xA5 to 0xAD, and the like reserved according to the provisions of ARIB STD-B10 can be used for setting the resolution.

  FIG. 6 is a diagram illustrating an example of setting the service format type and the resolution. In the example shown in the figure, service type types (service_type) 0xA5, 0xA6, and 0xA7 are set to mean resolutions of 2K, 4K, and 8K, respectively. In the MH-service list descriptor illustrated in FIG. 4, any one of 0xA5, 0xA6, and 0xA7 is described as the maximum resolution information in the service format type and transmitted, so that the reception device 10 stores the maximum resolution information of each service. Extract and identify the resolution of each service.

  FIG. 7 is a diagram illustrating an example of identifying the resolution of each service. In the illustrated example, since the service type (service_type) of the service identification (service_id) 0xABCD is 0xA5 in the MH-service list descriptor, the resolution of the 0xABCD service (video resolution) based on the resolution setting shown in FIG. Is identified as 2K. Further, since the service type (service_type) of service identification (service_id) 0xBCDA and 0xCDAB is 0xA6, the service resolution (video resolution) of 0xBCDA and 0xCDAB is identified as 4K. Further, since the service type (service_type) of service identification (service_id) 0xDABC is 0xA7, the resolution (video resolution) of the service of 0xDABC is identified as 8K.

  The SI analysis unit 104 analyzes the resolution for each service based on the information described in the MH-service list descriptor for each service as described above, and obtains maximum resolution information. The extraction unit 131 extracts the maximum resolution information for each service based on the analysis result analyzed by the SI analysis unit 104.

  Returning to FIG. 2, the operation information acquisition unit 132 acquires operation information based on a user operation. For example, the operation information acquisition unit 132 acquires operation information included in a control signal transmitted from the remote controller 20 via the external IF control unit 120.

  Based on the operation information (for example, operation information related to channel selection) acquired by the operation information acquisition unit 132, the channel selection unit 133 has information indicating a channel selection signal (for example, a broadcasting system, a channel, a program, etc.) for selecting a service. Output signal) to the receiving unit 101. The receiving unit 101 demodulates the received signal received based on the channel selection signal input from the channel selection unit 133. Further, the channel selection unit 133 controls a plurality of services to be selected according to resolution based on the maximum resolution information extracted by the extraction unit 131. Next, an example in which a plurality of services can be selected according to resolution will be specifically described.

  FIG. 8 is a diagram illustrating an example of operation keys of the remote controller 20. As shown in the figure, in the remote controller 20, a function as an operator for selecting a resolution is assigned to an up / down key for selecting an upward direction or a downward direction. On the other hand, a function as an operator for selecting a service is assigned to the left and right keys for selecting the left direction or the right direction. The remote controller 20 transmits operation information for the up and down keys and operation information for the left and right keys to the receiving device 10 in accordance with a user operation. The channel selection unit 133 acquires operation information for the up and down keys for selecting a resolution and operation information for the left and right keys for selecting a service, which are acquired by the external IF control unit 120 from the remote controller 20. To get through. For example, the channel selection unit 133 determines the resolution to be selected based on the operation information for the up / down keys, and controls to select only the service having the determined resolution based on the operation information for the left / right keys. As described above, the channel selection unit 133 determines the resolution to be selected based on the operation information for the up and down keys and the operation information for the left and right keys included in the control signal transmitted from the remote controller 20, for example. You can select a resolution-only service.

  FIG. 9 is a diagram for explaining an example of a channel selection operation method according to the present embodiment. For example, when the remote controller 20 performs an operation on an up / down key for selecting a resolution to be selected, the selected resolution is “ALL”, “8K”, “4K”, Transition is in the order of “2K”. “ALL” indicates that all resolutions (here, 8K, 4K, and 2K) are selected.

  For example, when the down key (DOWN) is operated in the state where the selection resolution is “ALL”, the selection resolution changes from “ALL” to “8K”. In the example shown in FIG. 7, since the service of “8K” is only 0xDABC, the service of 0xDABC is selected. If the lower key is further operated while the selected resolution is “8K”, the selected resolution changes from “8K” to “4K”. In the example shown in FIG. 7, since there are two “4K” services, 0xBCDA and 0xCDAB, in this state, these two services can be selected with the left and right keys. If the operation is further performed on the lower key in the state where the selected resolution is “4K”, the selected resolution changes from “4K” to “2K”. In the example shown in FIG. 7, since the service “2K” is only 0xABCD, the service of 0xABCD is selected. If the lower key is further operated while the selected resolution is “2K”, the selected resolution changes from “2K” to “ALL” (returns). In the example shown in FIG. 7, when the selected resolution is “ALL”, there are four services of 0xABCD, 0xBCDA, 0xCDAB, and 0xDABC. In this state, these four services can be selected with the left and right keys. If the operation on the lower key continues, the transition is repeated in the order of “ALL”, “8K”, “4K”, “2K”. On the other hand, in the operation with respect to the up key (UP), the transition is repeatedly made in the order of “ALL”, “2K”, “4K”, “8K” in the opposite direction.

  In the above example, an example has been described in which a function as an operator for selecting a resolution is assigned to the up and down keys, and a function as an operator for selecting a service is assigned to the left and right keys. The key assignment is not limited to this. FIG. 10 is a diagram illustrating another example of operation keys of the remote controller 20. For example, as shown in FIG. 10, even if a function as an operator for selecting a resolution is assigned to the left and right keys of the remote controller 20, and a function as an operator for selecting a service is assigned to the up and down keys. Good.

  Further, the display control unit 134 may display the resolution to be selected so that the user can recognize the resolution. For example, the display control unit 134 acquires information indicating the selected resolution from the channel selection unit 133, and converts an indicator lamp (not illustrated) provided in the receiving apparatus 10 as a resolution display unit that displays the selected resolution to the selected resolution. It may be turned on accordingly.

  FIG. 11 is a diagram illustrating a display example of the indicator lamp. In the illustrated example, indicator lamps that can be individually controlled to be turned on and off are arranged in the vertical direction in each of “ALL”, “2K”, “4K”, and “8K”. The order of arrangement corresponds to the order of transition in the operation for the up and down keys. Here, an example in which the selected resolution is “ALL” is shown, and only the “ALL” indicator lamp is lit.

  The indicator lamps may be arranged side by side in the left-right direction. FIG. 12 is a diagram illustrating a display example when the indicator lamps are arranged side by side in the left-right direction. For example, when the resolution is selected with the left and right keys as in the example of the operation keys shown in FIG. 10, the user can operate intuitively if the indicator lamps are also arranged in the left and right direction. .

  The indicator lamp may be provided on the remote controller 20. For example, the remote controller 20 may control lighting of an indicator lamp provided on the remote controller 20 according to an operation of an up / down key or the like. When the receiving device 10 and the remote controller 20 can communicate bidirectionally, the remote controller 20 acquires information indicating the selected resolution from the receiving device 10 and an indicator provided in the remote controller 20 based on the acquired information. The lighting of the lamp may be controlled.

  Note that the resolution display unit that displays the selected resolution is not limited to the indicator lamp, and may be the display when the receiving device 10 or the remote controller 20 includes a display (display unit). . For example, when the receiving apparatus 10 or the remote controller 20 includes a display, characters or icons indicating the selected resolution may be displayed on the display.

  In this way, the receiving device 10 or the remote controller 20 can display the resolution to be selected, that is, the resolution of the service that can be selected by the operation of selecting a channel, so that the user can recognize it.

(Operation of tuning operation control processing)
Next, with reference to FIG. 13, the operation of the channel selection operation control process for selecting a service for each resolution according to a user operation will be described.
FIG. 13 is a flowchart illustrating an example of the channel selection operation control process according to the present embodiment. Here, as shown in FIG. 8, an example of processing when the up / down keys are used for resolution selection and the left / right keys are used for channel selection is shown.

  (Step S101) The receiving apparatus 10 determines the current resolution selected by the up / down key. For example, the receiving apparatus 10 determines the current resolution by holding information indicating the resolution selected immediately before.

  (Step S <b> 102) Based on the operation information acquired from the remote controller 20, the receiving apparatus 10 determines whether or not an operation key is pressed on the remote controller 20. If it is determined that the operation key has not been pressed (NO), the receiving apparatus 10 returns the process to step S101. On the other hand, if it is determined that the operation key has been pressed (YES), the receiving apparatus 10 proceeds to the process of step S103.

  (Step S103) The receiving apparatus 10 determines whether or not the pressed operation key of the remote controller 20 is an up / down (UP / DOWN) key. If it is determined that the pressed operation key of the remote controller 20 is the up / down (UP / DOWN) key (YES), the receiving apparatus 10 proceeds to the process of step S104. On the other hand, when it is determined that the pressed operation key of the remote controller 20 is not the up / down (UP / DOWN) key (NO), the receiving apparatus 10 proceeds to the process of step S109.

  (Step S104) The receiving apparatus 10 determines whether the pressed key is an up / down (UP / DOWN) key. If it is determined that the pressed key is the up (UP) key, the receiving apparatus 10 proceeds to the process of step S105. On the other hand, if it is determined that the pressed key is the down (DOWN) key, the receiving apparatus 10 proceeds to the process of step S107.

(Step S105) The receiving apparatus 10 counts the number of times “X” the user has pressed the up (UP) key, and proceeds to the process of step S105.
(Step S106) The receiving apparatus 10 selects a resolution advanced by “X” above the current resolution (a resolution advanced by “X” from the current resolution in the order of resolution transition by the up key operation), and the step The process returns to S101.

(Step S107) The receiving apparatus 10 counts the number of times “X” the user has pressed the down (DOWN) key, and proceeds to the process of step S108.
(Step S108) The receiving apparatus 10 selects a resolution advanced by "X" downward from the current resolution (a resolution advanced by "X" from the current resolution in the order of transition of resolution by the down key operation), and step The process returns to S101.

  (Step S109) If it is determined in step S103 that the pressed operation key of the remote controller 20 is not an up / down (UP / DOWN) key (NO), the receiving apparatus 10 determines that the pressed operation key of the remote control 20 is left or right. Determine whether the key. When it is determined that the pressed operation key of the remote controller 20 is the left / right key (YES), the receiving apparatus 10 proceeds to the process of step S110. On the other hand, when it is determined that the pressed operation key of the remote controller 20 is not the left / right key (NO), the receiving apparatus 10 proceeds to the process of step S120.

(Step S110) The receiving apparatus 10 selects a service within the same resolution as the selected resolution, and returns to the process of Step S101.
(Step S <b> 120) The receiving apparatus 10 performs a process related to operation keys other than the up / down key and the left / right key in the remote controller 20, and returns to the process of step S <b> 101.

As described above, the receiving device 10 according to this embodiment includes the extraction unit 131 and the channel selection unit 133. The extraction unit 131 extracts additional information (for example, maximum resolution information) related to the resolution added for each of a plurality of services that provide video content. The channel selection unit 133 selects a plurality of services for each resolution based on the additional information extracted by the extraction unit 131.
Thereby, the receiving apparatus 10 can select a service with a desired resolution because it can select a channel according to the resolution even when a plurality of services with different resolutions are provided.

For example, the receiving device 10 includes an operation information acquisition unit 132 that acquires operation information based on a user operation. The operation information acquisition unit 132 is a first operation information for selecting a resolution (for example, first operation information for an up / down key) and a second operation element for selecting a service (for example, a left / right key). ) To obtain second operation information. The channel selection unit 133 determines a resolution to be a channel selection target based on the first operation information acquired by the operation information acquisition unit 132, and determines based on the second operation information acquired by the operation information acquisition unit 132. Only services that provide video content with the specified resolution are selected.
Thereby, the receiving apparatus 10 can select a service with a desired resolution from a plurality of services with different resolutions by a simple operation.

For example, a first operation element (for example, up / down key) and a second operation element (for example, left / right key) are provided in a remote controller 20 (remote operation apparatus) that transmits a control signal to the reception apparatus 10. . Then, the channel selection unit 133 determines the resolution to be selected based on the first operation information and the second operation information included in the control signal transmitted from the remote controller 20, and the video content with the determined resolution. Select the service to be provided.
Thereby, the receiving apparatus 10 can select a service with a desired resolution from among a plurality of services with different resolutions by a user performing a simple operation with the remote controller 20.

Note that the receiving apparatus 10 includes a display control unit 134 that displays the resolution that is selected by the channel selection unit 133 so that the user can recognize the resolution.
Thereby, since the receiving apparatus 10 can display the indicator lamp or the like during the operation, it can improve the operability when the user selects a channel.

In addition, the remote controller 20 (remote control device) according to the present embodiment includes a first operator (for example, an up / down key) for selecting a resolution and a second operator (for example, a channel for selecting a service). Left and right keys). Then, the remote controller 20 transmits the first operation information for the first operator and the second operation information for the second operator in accordance with a user operation.
Thus, the remote controller 20 can select a service with a desired resolution easily because the remote controller 20 can select a channel by resolution even when the receiving apparatus 10 can receive a plurality of services with different resolutions.

The remote controller 20 (remote control device) is an indicator lamp (resolution display) that displays the resolution of services that can be selected by the user's operation on the second operator (for example, the left and right keys) so as to be recognized by the user. It is good also as a structure provided with the example of a part.
As a result, the remote controller 20 can display an indicator lamp or the like during operation to determine which resolution channel selection is possible, so that the operability when the user selects a channel can be improved.

  As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above, and various design changes and the like can be made without departing from the scope of the present invention. It is possible to

  For example, in the above embodiment, the operation key may be in the receiving device 10. The example has been described in which the remote controller 20 includes a first operator (for example, up / down key) for selecting a resolution and a second operator (for example, the left / right key) for selecting a service. However, the present invention is not limited to this, and the receiver 10 may be provided. Further, the first operation element (for example, the up / down key) for selecting the resolution and the second operation element (for example, the left / right key) for selecting the service are both the receiving device 10 and the remote controller 20. May be provided.

  In the above-described embodiment, the example in which the receiving device 10 is a television device has been described. However, the receiving device 10 is a television broadcast recorder (hard disk recorder or the like), a personal computer having a function of receiving a broadcast signal. A multi-function mobile phone (including a so-called smartphone), a tablet terminal device, or the like may be used.

  Note that some functions of the receiving device 10 in the above-described embodiment may be realized by a computer. In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed. Here, the “computer system” is a computer system built in the receiving apparatus 10 and includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Further, the “computer-readable recording medium” is a medium that dynamically holds a program for a short time, such as a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line In such a case, a volatile memory inside a computer system serving as a server or a client may be included and a program that holds a program for a certain time. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  Further, at least a part of the receiving device 10 may be realized as an integrated circuit such as an LSI (Large Scale Integration). Each component in the receiving apparatus 10 of the present embodiment may be individually made into a processor, or at least a part thereof may be integrated into a processor. Further, the method of circuit integration is not limited to LSI, and may be realized by a dedicated circuit or a general-purpose processor. In addition, when an integrated circuit technology that replaces LSI appears due to the advancement of semiconductor technology, an integrated circuit based on the technology may be used.
