  The operation of the present invention will be described below. FIG. 9 is a flowchart showing processes of the control unit 2 of the AV amplifier 1 and the control unit of the content reproduction apparatus. The control unit 2 of the AV amplifier 1 determines whether or not an instruction to change the input selector is input by a user operation (S1). When an instruction to change the input selector is input (YES in S1), for example, when the Blu-ray selector is selected, the control unit 2 switches the input selector to the Blu-ray selector (S2). That is, the control unit 2 causes the selector switch 5 to select the input terminal IN2 to which the Blu-ray player 20 is connected.

  The control unit 2 requests the content playback device (in this example, the Blu-ray player 20) corresponding to the selected input selector to transmit a command list (command information) (S3). In response to a request from the AV amplifier 1, the control unit 22 of the Blu-ray player 20 acquires a command list (command information) from the memory 23 and transmits it to the control unit 2 of the AV amplifier 1 (S11). When receiving the command list from the Blu-ray player 20, the control unit 2 of the AV amplifier 1 stores it in the memory 3 (S3).

  The control unit 2 compares the command list of the AV amplifier 1 (FIG. 3) with the command list of the Blu-ray player 20 (FIG. 5) (S4). And the control part 2 extracts the operation content common to both, and memorize | stores it in the memory 3 as shown in FIG. 7 (S5). In the example of FIG. 7, “play”, “stop”, “pause”, “fast forward”, “fast reverse”, “skip up”, “skip down”, “decision”, “return”, “setting” are set. The operation content is common to both.

  As shown in FIG. 4, the control unit 2 causes the display unit 4 to display operation contents (FIG. 7) common to the command list of the AV amplifier 1 and the command list of the Blu-ray player 20 (S5). Therefore, the user can know a command (operation button) that can operate the Blu-ray player 20 without referring to the instruction manual separately by referring to the display content.

  For example, when the user refers to the display content and operates the playback button of the remote control transmitter 40, the control unit 2 of the AV amplifier 1 receives the playback command from the remote control transmitter 40 and via the communication unit 4, the Blu-ray player A playback command is transmitted to 20. When receiving a playback command from the AV amplifier 1, the control unit 22 of the Blu-ray player 20 starts playback of the Blu-ray disc in response to the playback command.

  When an operation button other than the operation content common to the command list of the AV amplifier 1 and the command list of the Blu-ray player 20 is operated, the control unit 2 displays on the display unit 8 that the operation is invalid. You may let them. This process is shown in the flowchart of FIG.

  When the remote control command is received from the remote control transmitter 40 (YES in S6), the control unit 2 determines whether or not the content reproduction device corresponding to the selected input selector can execute processing in response to the remote control command. Judgment is made (S7). That is, it is determined whether or not the input command is the operation content common to the command list of the AV amplifier 1 and the command list of the Blu-ray player 20. For example, when the input selector is a Blu-ray selector, is the operation content of the received remote control command included in the operation content common to the command list of the AV amplifier 1 and the command list of the Blu-ray player 20 shown in FIG. Judge whether or not.

  For example, if the received remote control command is a playback command, it is included in the operation contents common to the command list of the AV amplifier 1 and the command list of the Blu-ray player 20 as shown in FIG. 7 (YES in S7). The control unit 2 transmits a playback command to the content playback device (Blu-ray player 20) selected by the input selector (S8). When receiving a playback command from the AV amplifier 1, the control unit 22 of the Blu-ray player 20 starts playback of the Blu-ray disc in response to the playback command.

  For example, if the received remote control command is a cursor up command, as shown in FIG. 7, it is not included in the operation content common to the command list of the AV amplifier 1 and the command list of the Blu-ray player 20 (NO in S7). . That is, the cursor up command is included in the command list of the AV amplifier 1 but is not included in the command list of the Blu-ray player 20. Therefore, it is determined that the Blu-ray player 20 cannot execute the processing even when the cursor up command is received from the AV amplifier 1.

  Therefore, the control unit 2 does not transmit a cursor up command to the content playback device (Blu-ray player 20) selected by the input selector. Then, the control unit 2 displays on the display unit 8 that the Blu-ray player 20 cannot be operated with the cursor up command (button) and notifies the user (S9). Thereby, the user can recognize that he / she has operated the wrong button, and can prevent the user from misunderstanding that any device is out of order.

  Next, another preferred embodiment of the present invention will be described. In this example, as shown in FIG. 11, instead of displaying the operation content common to the command list of the AV amplifier 1 and the command list of the Blu-ray player 20 on the display unit 8, this information is transmitted to the remote control transmitter 40. (S6). In this case, the remote control transmitter 40 is of a bidirectional type, and can receive this information from the AV amplifier 1 via a network such as infrared, Bluetooth, or LAN.

  When the remote controller transmitter 40 receives from the AV amplifier 1 the operation content common to the command list of the AV amplifier 1 and the command list of the Blu-ray player 20, the remote control transmitter 40 emits a button corresponding to the operation content (for example, emits an LED). Thus, a command (button) that can be executed by the content reproduction apparatus corresponding to the selected input selector is notified to the user (S31). For example, a play button or a stop button of the remote control transmitter 40 is illuminated.

  Alternatively, when the remote control transmitter 40 receives from the AV amplifier 1 the common operation content in the command list of the AV amplifier 1 and the command list of the Blu-ray player 20, the remote control transmitter 40 displays the common operation content in the remote control transmitter 40. A command (button) that can operate the content reproduction device corresponding to the selected input selector may be notified to the user by displaying on the display unit that does not.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. The command information common to the content playback apparatus and the AV amplifier shown in FIGS. 7 and 8 may be held until the content playback apparatus disconnects from the AV amplifier. In this case, the input selector is switched. There is no need to obtain a command list from the content playback device each time. The present invention can be applied not only to an AV amplifier but also to a display device such as a TV receiver having a plurality of input terminals. You may provide with the form of the program for making a computer perform the said operation | movement of a command information notification apparatus, and the recording medium which recorded this.

  The present invention can be suitably employed in an AV amplifier or the like.
