In the specific example shown in FIG. 7B, the operation menu screen 26 is operated. The target device menu is displayed in a list form in which the target device menus are arranged vertically, and in each case, a frame-shaped cursor 27 is displayed so as to overlap with this. This cursor 27 can be moved by operating the cursor button 10 (FIG. 1) of the multi remote controller 1, and the operation of the cursor 27 is determined by operating the enter button 11 (FIG. 1). In the initial state, the cursor 27 overlaps the first power key 26a. The operation buttons displayed on the operation menu screen 26 will be referred to as operation keys below.

Next, the operation menu screen for the internally connected device which is the operation target device shown in FIG. 8 will be described.
Note that FIGS. 8A and 8B show specific examples of different operation menu screens for the internally connected devices.

In FIGS. 8 (a) and 8 (b), when the control identification code is for a predetermined internal connection device to the operation target device, the broadcast program received on the entire TV screen 20 and the reproduced video of the operation target device are displayed. The display unit 25 of the operation menu screen (operation target device menu) 28 of the operation target device is displayed so as to be displayed on the screen.

In the specific example shown in FIG. 8A, the operation menu screen 28 of various operation menus is displayed in the form of a remote controller, and in the specific example shown in FIG. 8B, the operation menu screen 26 is the operation menu. Are displayed in the form of a list arranged vertically, and in each case, a frame-shaped cursor 27 is displayed so as to be overlaid on it. This cursor 27
Can also be moved by operating the cursor button 10 (FIG. 1) of the multi remote controller 1, and by operating the enter button 11 (FIG. 1), the operation menu with the cursor 27 overlapped is determined. In the initial state, the cursor 27 overlaps the first power key 28a.
