[Processing flow for initial settings]
Subsequently, a flow of processing in the receiving system S will be described. First, processing related to the initial setting in the receiving system S will be described. FIG. 5 is a sequence diagram illustrating a flow of processing related to the initial setting in the receiving system S according to the present embodiment.

  First, the receiver 1 and the remote controller 2 perform pairing of short-range wireless communication (S10). For example, when each of the operation unit 11 of the receiving device 1 and the operation unit 21 of the remote controller 2 receives a predetermined operation related to the initial setting, the wireless communication unit 13 of the operation unit 11 and the wireless communication unit 22 of the remote controller 2 Pairing is performed by performing short-range wireless communication.

  Subsequently, the acquisition unit 151 of the reception device 1 acquires information about the television receiver 4 from the television receiver 4 via the HDMI cable HC and the communication unit 12 (S20). Specifically, the acquisition unit 151 can use the HDMI-CEC, and, as information on the television receiver 4, the manufacturer, model number, resolution, and television receiver 4 of the television receiver 4 Of HDCP (High-Bandwidth Digital Content Protection).

  Subsequently, based on the acquired information on the television receiver 4, the second transmission control unit 153 determines whether or not the television receiver 4 can receive a second broadcast signal that is not received by the reception device 1. Information is generated (S30). For example, the second transmission control unit 153 stores the correspondence information in which the manufacturer of the television receiver 4, the model number, and information indicating whether or not the television receiver 4 can receive the second broadcast signal are associated with the external server (not shown). (Shown). Then, the second transmission control unit 153 determines whether or not the television receiver 4 can receive the second broadcast signal based on the correspondence information and the manufacturer and model number included in the information on the television receiver 4. . The second transmission control unit 153 generates television receiver information based on the determination result. In the present embodiment, it is assumed that the television receiver 4 can receive the second broadcast signal.

  The second transmission control unit 153 determines whether or not the television receiver 4 can receive the second broadcast signal based on the resolution included in the information on the television receiver 4 and the HDCP version, and The television receiver information may be generated based on the determination result.

  Subsequently, the second transmission control unit 153 specifies the format of the information that can be received by the television receiver 4 based on the acquired information on the television receiver 4 (S40). For example, the second transmission control unit 153 obtains, from the external server, receiver-specific format information in which the manufacturer of the television receiver 4, the model number, and the information format indicated by the infrared signal of the remote controller 2 are associated with each other. The second transmission control unit 153 specifies the format of the information related to the manufacturer and model number of the television receiver 4 included in the information on the television receiver 4 with reference to the receiver-specific format information. The second transmission control unit 153 causes the storage unit 14 to store format information indicating the format of the specified information.

  The format information for each receiver may be information in which the manufacturer and model number of the television receiver 4, the model number of the remote controller, and the format of the information indicated by the infrared signal of the remote controller are associated. Then, the second transmission control unit 153 may specify the model number of the remote controller 2. The second transmission control unit 153 transmits the manufacturer and model number of the television receiver 4 and the model number of the remote controller 2 to the external server, and obtains, from the external server, receiver-specific format information corresponding to the manufacturer and model number May be.

Subsequently, the second transmission control unit 153 transmits the generated television receiver information and the format information indicating the format of the specified information to the remote control 2 by the wireless communication unit 13 (S50).
When the wireless communication unit 22 receives the television receiver information and the format information from the receiving device 1, the control unit 25 of the remote controller 2 causes the storage unit 24 to store the information as setting information (S60). When the processing in S60 ends, the initialization processing ends.

  Note that the television receiver 4 is assumed to be a television receiver sold by various manufacturers, and keys that can be used as the common button 212 differ depending on the type of the television receiver 4. For this reason, the remote controller 2 may assign a necessary common button according to the type of the television receiver 4. For example, button identification information (operation setting information) for identifying a button used as the shared button 212 on the remote controller 2 is associated with the receiver-specific format information. Then, the second transmission control unit 153 may set the common button 212 of the remote controller 2 based on the button identification information included in the obtained receiver-specific format information. Then, the first transmission control unit 251 may specify the shared button 212 based on the button identification information. By doing so, a button suitable for each type of the television receiver 4 can be used as the common button 212.

[Process Flow in STB Operation Mode]
Subsequently, a process when the remote controller 2 is operated in the receiving system S will be described. The remote controller 2 has, as operation modes, an STB operation mode for operating the receiver 1 and a TV operation mode for operating the television receiver 4. First, the processing when the operation mode of the remote controller 2 is the STB operation mode will be described.

  When the operation mode of the remote controller 2 is the STB operation mode, the first transmission control unit 251 uses the operation unit 21 to perform an operation different from an operation of selecting a broadcast corresponding to the second broadcast signal, that is, the common button 212 or When the operation (second operation) of the STB dedicated button 213 is received, the wireless communication unit 22 is caused to transmit operation information (second operation information indicating the second operation) corresponding to the operated button.

  When the wireless communication unit 13 receives the second operation information, the display control unit 154 of the receiving device 1 displays a screen corresponding to the second operation. For example, when the second operation is an operation of selecting a channel, the display control unit 154 extracts a broadcast signal corresponding to the selected channel from the first broadcast signal received by the communication unit 12, and outputs the extracted broadcast signal to the broadcast signal. A video signal and an audio signal are extracted based on the video signal and the audio signal. The display control unit 154 outputs the extracted video signal and audio signal to the television receiver 4 via the communication unit 12 and the HDMI cable HC to receive the video and audio corresponding to the video signal and the audio signal. Output to the machine 4.

  When the operation unit 21 receives an operation of selecting a broadcast corresponding to the second broadcast signal, that is, an operation of the 4K button 211 (first operation), the first transmission control unit 251 causes the transmission unit 23 to transmit the 4K button 211 The first operation information indicating that has been operated is transmitted. Here, the first transmission control unit 251 specifies the first operation information in a format receivable by the television receiver 4 based on the format information stored in the storage unit 24, and transmits the first operation information. The part 23 is transmitted.

FIG. 6 is a flowchart illustrating the flow of processing of the remote controller 2 when the 4K button 211 according to the present embodiment is operated.
First, when the 4K button 211 is operated, the first transmission control unit 251 determines whether or not the television receiver 4 supports the second broadcast signal (S110). Specifically, when the 4K button 211 is operated, the first transmission control unit 251 refers to the television receiver information stored in the storage unit 24 and allows the television receiver 4 to receive the second broadcast signal. It is determined whether or not. When the first transmission control unit 251 determines that the television receiver 4 can receive the second broadcast signal, the process proceeds to S120, and causes the transmission unit 23 to transmit the first operation information.

The first operation information includes, for example, information for instructing input switching of the television receiver 4 and one channel corresponding to the 4K broadcast, or a channel of the 4K broadcast (last channel) displayed last. Channel selection information to be included. Upon receiving the first operation information, the television receiver 4 switches the screen to be displayed to a screen for outputting a video based on the second broadcast signal received by the television receiver 4 and supports the selected 4K broadcast channel. Output video and audio.
Subsequently, the first transmission control unit 251 switches the operation mode of the remote controller 2 from the STB operation mode to the television operation mode (S130).

  When the first transmission control unit 251 determines in S110 that the television receiver 4 does not receive the second broadcast signal, the process proceeds to S140, and the television communication unit 22 transmits the broadcast signal to the wireless communication unit 22. The receiving device 1 is caused to transmit error information indicating that no reception is performed. When the wireless communication unit 13 receives the error information, the display control unit 154 of the receiving device 1 causes the television receiver 4 to display information indicating that the television receiver 4 does not support 4K broadcasting. By doing so, the user can know that the television receiver 4 does not support 4K broadcasting.

[Processing flow when in TV operation mode]
Subsequently, a process when the operation mode of the remote controller 2 is the television operation mode will be described. The first transmission control unit 251 causes the transmission unit 23 to transmit the first operation information, switches the operation mode of the remote controller 2 to the television operation mode, and then uses the operation unit 21 to perform a plurality of operations corresponding to the second operation. When the third operation, which is a part of the operation, is received, the transmitting unit 23 transmits the third operation information indicating the third operation, and among the plurality of operations corresponding to the second operation, When a fourth operation, which is a different operation, is received, the wireless communication unit 22 is caused to transmit fourth operation information indicating the fourth operation.

FIG. 7 is a flowchart illustrating a flow of processing when the remote controller 2 according to the present embodiment operates in the television operation mode.
First, the first transmission control unit 251 determines whether the STB dedicated button 213 has been operated (S210). If the first transmission control unit 251 determines that the STB dedicated button 213 has been operated, the process proceeds to S220. If it determines that the STB dedicated button 213 has not been operated, the process proceeds to S240.

  In S220, when the first transmission control unit 251 receives an operation (fourth operation) of the STB dedicated button 213 among a plurality of operations corresponding to the second operation, the wireless communication unit 22 causes the operated STB dedicated button to be operated. Operation information (fourth operation information) corresponding to 213 is transmitted to the receiving device 1. When the wireless communication unit 13 receives the fourth operation information, the display control unit 154 of the receiving device 1 causes the television receiver 4 to display a screen corresponding to the operated STB dedicated button 213.

  Subsequently, the first transmission control unit 251 switches the operation mode of the remote controller 2 from the television operation mode to the STB operation mode (S230). As described above, since the operation mode of the remote controller 2 is switched from the television operation mode to the STB operation mode, the first transmission control unit 251 causes the wireless communication unit 22 to transmit the fourth operation information, and then performs the third operation. When the common button 212 is received, the wireless communication unit 22 transmits the third operation information. Therefore, the user can easily switch between the operation of the television receiver 4 by the remote controller 2 and the operation of the receiving device 1.

  When the power button of the STB dedicated button 213 is pressed, the first transmission control unit 251 switches the operation mode of the remote controller 2 from the television operation mode to the STB operation mode. Operation information indicating that the power button has been pressed is transmitted to the receiving device 1.

  When the first transmission control unit 251 determines that the STB dedicated button 213 has not been operated in S210, it determines whether the shared button 212 has been operated (S240). If the first transmission control unit 251 determines that the common button 212 has been operated, the process proceeds to S250. If the first transmission control unit 251 determines that the common button 212 has not been operated, the process proceeds to S210.

  In S250, the first transmission control unit 251 causes the transmission unit 23 to transmit operation information (third operation information) corresponding to the shared button 212. Here, the first transmission control unit 251 specifies the third operation information in a format receivable by the television receiver 4 based on the format information stored in the storage unit 24, and transmits the third operation information.

When the integrated program table is already stored in the storage unit 14, the generation unit 152 updates the integrated program table stored in the storage unit 14 with the obtained integrated program table.

[Display program guide]
The receiving device 1 causes the television receiver 4 to display the integrated program guide when the remote control 2 is operating in the STB operation mode. For example, when the first transmission control unit 251 of the remote controller 2 receives the operation of the program guide button, the first communication control unit 251 transmits, to the receiving device 1, operation information for instructing display of the program guide by the wireless communication unit 22. When the wireless communication unit 13 receives the operation information, the display control unit 154 of the receiving device 1 causes the television receiver 4 to display the integrated program guide stored in the storage unit 14.

[Recording registration operation via program guide]
Next, a process related to a recording registration operation via the integrated program guide will be described. When the integrated program guide is displayed on the television receiver 4, the receiving device 1 can register the recording of the program by accepting the operation of the integrated program guide via the remote controller 2. Hereinafter, the processing of the receiving device 1 related to the recording registration operation via the integrated program guide will be described.

  FIG. 9 is a flowchart illustrating a flow of processing related to a recording registration operation in the receiving device 1 according to the present embodiment. It is assumed that the integrated program guide is displayed on the television receiver 4 at the start of the flowchart.

  First, the recording registration unit 155 receives a recording registration operation (S410). For example, when the first transmission control unit 251 of the remote controller 2 receives a recording registration operation from the user, the first transmission control unit 251 transmits recording operation information to the receiving device 1. Here, the recording registration operation is, for example, an operation of selecting a recording button in a state where one program is selected in the integrated program table. When the wireless communication unit 13 of the receiving device 1 receives the recording operation information, the recording registration unit 155 receives the recording registration operation.

  Subsequently, the recording registration unit 155 selects a program to be recorded based on the information of the program included in the integrated program guide (S420). For example, when receiving the recording registration operation, the recording registration unit 155 selects the program currently selected in the integrated program guide as the program to be recorded.

  Subsequently, the recording registration unit 155 determines whether or not the selected program is a program corresponding to the first broadcast signal (S430). For example, the recording registration unit 155 specifies a channel corresponding to a program based on information on the selected program included in the integrated program table. The recording registration unit 155 determines whether or not the selected program is a program corresponding to the first broadcast signal based on the specified channel.

  When the recording registration unit 155 determines that the selected program corresponds to the first broadcast signal, the process proceeds to S440, and causes the recording unit 156 to perform recording registration of the program. For example, the recording registration unit 155 is generated by channel information indicating a channel corresponding to a program to be recorded, title information indicating a title of the program, recording time information indicating a start time and an end time of the program, and recording. And recording information including quality information indicating the quality of the moving image to be stored. The recording unit 156 records a program corresponding to the first broadcast signal based on the recording registration information stored in the storage unit 14. The recording unit 156 records the program corresponding to the first broadcast signal by storing moving image information indicating the program in the storage unit 14.

  If the selected program does not correspond to the first broadcast signal, the recording registration unit 155 determines that the selected program corresponds to the second broadcast signal, and shifts the processing to S450. In S450, the recording registration unit 155 causes the remote recording server 6 to perform recording registration of the program. For example, the recording registration unit 155 transmits recording registration information including channel information, title information, recording time information, and quality information to the remote recording server 6. Upon receiving the recording registration information, the remote recording server 6 performs recording registration of the program by storing the recording registration information in its own storage unit. The television receiver 4 accesses the remote recording server 6, specifies a newly-registered program, and records the program. The television receiver 4 may store the recording registration information corresponding to the recorded program in its own storage unit. By doing so, the user can easily record a program from the integrated program guide without being aware of the recording device and the type of broadcast signal. The remote recording server 6 may cause the television receiver 4 to register the recording of the program by notifying the television receiver 4 of the registered program.
