The control unit 25 is, for example, a CPU. The control unit 25 includes a first transmission control unit 251. Details of the function of the first transmission control unit 251 will be described later.

[Flow of processing related to initial settings]
Next, the 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 showing a flow of processing relating to the initial setting in the receiving system S according to the present embodiment.

  First, the receiving device 1 and the remote controller 2 perform short-range wireless communication pairing (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 control 2 are Pairing is performed by short-range wireless communication.

  Subsequently, the acquisition unit 151 of the reception device 1 acquires information related to 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 handle the manufacturer, model number, resolution, and television receiver 4 of the television receiver 4 as information about the television receiver 4 from the television receiver 4 using HDMI-CEC. Information indicating the version of HDCP (High-Bandwidth Digital Content Protection) is acquired.

  Subsequently, the second transmission control unit 152 functions as a generation unit, and based on the acquired information about the television receiver 4, whether or not the television receiver 4 can receive the second broadcast signal that is not received by the receiving device 1. TV receiver information indicating such is generated (S30). For example, the second transmission control unit 152 determines whether the television receiver 4 can receive and display the second broadcast signal based on the resolution included in the information related to the television receiver 4 and the HDCP version. Then, television receiver information is generated based on the determination result.

  Subsequently, the second transmission control unit 152 functions as a specifying unit, and specifies the format of information that can be received by the television receiver 4 based on the acquired information about the television receiver 4 (S40). For example, the second transmission control unit 152 acquires, from an external server (not shown), receiver-specific format information that associates the manufacturer of the television receiver 4, the model number, and the format of information indicated by the infrared signal of the remote controller 2. . The second transmission control unit 152 refers to the receiver-specific format information and identifies the format of information related to the manufacturer and model number of the television receiver 4 included in the information related to the television receiver 4.

Subsequently, the second transmission control unit 152 transmits the generated television receiver information and format information indicating the format of the specified information to the remote controller 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 stores these information as setting information in the storage unit 24 (S60). When the process according to S60 ends, the initial setting process ends.

  In the present embodiment, the television receiver 4 is assumed to be a television receiver sold by various manufacturers, and a key that can be used as the shared button 212 differs depending on the type of the television receiver 4. For this reason, the remote controller 2 may assign a necessary shared 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 in the remote controller 2 is associated with the receiver-specific format information. Then, the second transmission control unit 152 may set the shared button 212 of the remote controller 2 based on the button identification information included in the acquired 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 in this way, the button suitable for every model of the television receiver 4 can be used as the common button 212.

[Processing flow in STB operation mode]
Next, processing 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 that is a mode for operating the receiving device 1 and a television operation mode that is a mode for operating the television receiver 4. First, 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 the 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 accepted, 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 153 of the receiving device 1 displays a screen corresponding to the second operation. For example, when the second operation is an operation for selecting a channel, the display control unit 153 extracts a broadcast signal corresponding to the selected channel from the first broadcast signal received by the communication unit 12, and uses the broadcast signal as the broadcast signal. Based on this, a video signal and an audio signal are extracted. The display control unit 153 outputs the extracted video signal and audio signal to the television receiver 4 via the communication unit 12 and the HDMI cable HC, thereby transmitting the video and audio corresponding to the video signal and the audio signal to the television. It is displayed on the receiver 4.

  In addition, when the operation unit 21 receives an operation for 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 4K. First operation information indicating that the button 211 has been operated is transmitted. Here, the first transmission control unit 251 specifies the first operation information in a format that can be received by the television receiver 4 based on the format information stored in the storage unit 24, and transmits the first operation information. Sending to the unit 23.

FIG. 6 is a flowchart showing a processing flow 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 is compatible with 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 the television receiver 4 can 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 first transmission control unit 251 moves the process to S120 and causes the transmission unit 23 to transmit the first operation information.

The first operation information includes, for example, information for instructing the input switching of the television receiver 4 and one channel corresponding to 4K broadcast, or the last displayed 4K broadcast channel (last channel). Channel selection information to be included. When the television receiver 4 receives the first operation information, the television receiver 4 switches the screen to be displayed to a screen that outputs an image based on a broadcast signal received by the television receiver 4, and an image corresponding to the selected 4K broadcast channel. And output 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).

  If the first transmission control unit 251 determines in S110 that the television receiver 4 does not receive the second broadcast signal, the first transmission control unit 251 proceeds to S140, and the wireless communication unit 22 causes the television receiver 4 to transmit the broadcast signal. Error information indicating that it is not received is transmitted to the receiving apparatus 1. When the wireless communication unit 13 receives the error information, the display control unit 153 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 in this way, the user can grasp that the television receiver 4 does not support 4K broadcasting.

[Processing flow when in TV operation mode]
Next, processing 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 transmission unit 23 transmits the third operation information indicating the third operation. Among the plurality of operations corresponding to the second operation, When a fourth operation that 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 showing a processing flow 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 or not 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 the first transmission control unit 251 determines that the STB dedicated button 213 has not been operated, the first transmission control unit 251 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 first communication control unit 251 operates the STB dedicated button operated by the wireless communication unit 22. 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 153 of the reception 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). Thus, 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 transmits the fourth operation information to the wireless communication unit 22 and then performs the third operation. When the common button 212 is received, the wireless communication unit 22 is caused to transmit 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.

  The first transmission control unit 251 switches the operation mode of the remote controller 2 from the TV operation mode to the STB operation mode when the power button of the STB dedicated buttons 213 is pressed, and then the wireless communication unit 22 performs the operation. Operation information indicating that the power button has been pressed is transmitted to the receiving device 1.

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