Also, when an instruction to move up and down the setting item hierarchy is input (YES in S118), that is, when the determination key is operated while the cursor is displayed on the desired setting item, or the return key is operated. If so, in the area 51 indicating the AV amplifier setting item or the area 52 indicating the BD player setting item, the level of the displayed setting item is moved up and down (S119).

  For example, in FIG. 3A, in the area 52 indicating the BD player setting item, when the determination button is operated while the cursor is displayed on “1. Video”, as shown in FIG. Each of the setting items in the hierarchy one level lower than “1. Video” is displayed. Further, in FIG. 3B, in the area 52 indicating the BD player setting item, when the determination button is operated in a state where the cursor is displayed on the “TV screen shape”, as shown in FIG. Each of the setting items in the hierarchy one level below the “TV screen shape” is displayed. In FIG. 3C, if the setting item currently set in the BD player 10 is “4: 3 letter box”, the cursor is displayed in advance in “4: 3 letter box”, and the current BD is displayed. If the setting item set in the player 10 is “16: 9 wide”, the cursor is displayed in advance at “16: 9 wide”.

  The control unit 24 determines whether or not an instruction for determining the setting item is input in the region 51 indicating the AV amplifier setting item or the region 52 indicating the BD player setting item by a user operation (S120). That is, it is determined whether or not the determination button has been operated by the user operation in a state where the setting item of the lowest hierarchy is displayed and the cursor is displayed on the desired setting item.

  When an instruction to determine a setting item is input (YES in S120), it is determined whether or not the current setting mode is an AV amplifier setting mode (S121). If it is the AV amplifier setting mode (YES in S121), the control unit 24 sets the AV amplifier 20 to the setting item on which the cursor is displayed when the enter button is operated (S122).

  On the other hand, if it is not the AV amplifier setting mode but the BD player setting mode (NO in S121), the control unit 24 sets the BD so that the cursor is set to the setting item displayed when the determination button is operated. A setting change instruction including setting items is transmitted to the control unit 13 of the player 10 (S123).

  For example, in FIG. 3C, in the area 52 indicating the BD player setting item, when the determination button is operated while the cursor is displayed on “4: 3 letterbox”, “4: 3 letterbox” is displayed. Is transmitted to the control unit 13 of the BD player 10.

  The control unit 13 of the BD player 10 determines whether or not a setting change instruction has been received from the control unit 24 of the AV amplifier 20 (S202). If received (YES in S202), the control unit 13 changes the setting of the BD player 10 based on the setting item information included in the received setting change instruction (S203). For example, when a setting change instruction including information indicating “4: 3 letterbox” is received, the control unit 13 changes the setting of “TV screen shape” to “4: 3 letterbox”.

  Next, another preferred embodiment of the present invention will be described. In the memory 25 of the AV amplifier 20, information related to the setting items of the BD player 10 that are related (similar) to the setting items of the AV amplifier 20 is stored in advance. For example, when the resolution exists in the setting item of the AV amplifier 20 and the resolution is also included in the setting item of the BD player 10, it is managed in the memory 25 that these are related to each other.

  FIG. 6 is a flowchart showing the processing of this example, but the same reference numerals are given to the same processing as that of FIG. When an instruction to move the cursor up or down is input (YES in S118), the control unit 24 moves the cursor display position up or down in the AV amplifier setting item area 51 or the BD player setting item area 52. (S119). When an instruction to move up and down the setting item hierarchy is input (YES in S118), that is, when the enter key is operated while the cursor is displayed on the desired setting item or the return key is operated. In this case, in the area 51 indicating the AV amplifier setting item or the area 52 indicating the BD player setting item, the level of the displayed setting item is moved up and down (S119). At this time, for the setting item of the device that is not in the setting mode, the control unit 24 determines whether there is a setting item related to the currently selected setting item of the device that is in the setting mode. It is determined whether or not (S131). If it exists (YES in S131), the relevant setting item is automatically selected and displayed in the area for displaying the setting item of the device not in the setting mode (S132).

  For example, as shown in FIG. 7B, in the BD player setting mode, if the cursor of the area 52 indicating the BD player setting item is moved to “resolution”, the relevance to the setting item “resolution” of the BD player is related. The presence / absence of a setting item of an AV amplifier is determined based on the management contents of the memory 25. Since “Resolution” exists as a setting item of the related AV amplifier, a cursor is displayed on “Resolution” in the area 51 indicating the AV amplifier setting item.

  Then, as shown in FIG. 7C, when the determination key is operated while the cursor is displayed on the “resolution” of the area 52 indicating the BD player setting item, the area 52 indicating the BD player setting item is displayed. Move to the next lower level and “AUTO”, “480I”, “480P”, “720P”, “1080I”, “1080P” are displayed. At this time, in the area 51 indicating the AV amplifier setting item, the determination key is automatically operated in a state where the cursor is displayed in “Resolution”, and the area 51 indicating the AV amplifier setting item is also moved down by one. To the next level, “AUTO”, “480I”, “480P”, “720P”, “1080I”, “1080P” are displayed. Then, the resolution (720P here) currently set in the AV amplifier is selected, and the cursor is displayed. Therefore, when the resolution of the BD player 10 is set, it can be set after confirming the information of the resolution currently set in the AV amplifier 20.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. For example, other communication lines such as LAN, USB, and IEEE1394 may be used instead of HDMI. A display device may be applied to the content receiving device instead of the AV amplifier. Further, the AV amplifier 20 may be defined as a content transmission device, and the display device may be defined as a content reception device. Further, the program may be provided in the form of a program for causing a computer to execute the above operations of the AV amplifier and the BD player, and a recording medium on which the program is recorded.
