In the same manner as described above, this drawing shows a wired connection. When inputting as a remote control (remote controller), a home-made cooperative code is generally used.
The generated key code is modulated into an infrared ray by an IR emitter attached to the control unit 8 and transmitted to an AVC device. When the menu key 25 is pressed, the control unit 8
The menu content is displayed on the display 5 by controlling the OSD included in the RGB processor 4. When selecting the displayed menu, it is necessary to move the cursor position on the menu screen by using four kinds of cursor keys, ie, a left key 27, a right key 28, an up key 29 and a down key 30. The control unit 11 detects the pressed position of the cursor key, and when detecting an arbitrary cursor key from 27 to 30, transmits a key code corresponding thereto. For example, when the right key 28 of the cursor key is pressed, the cursor located at the reference (default) position on the menu screen moves rightward.

Press 1. The control unit 11 detects the pressed position,
When the entry key 31 is detected, a key code corresponding to the entry key 31 is generated. When the entry key 31 is pressed, the control unit 8 detects the key code from the control unit 11 and performs a process according to the contents of the menu item. For example, if there is a timer setting in the menu, the control unit 8
Activates a timer counter provided therein.
In such a case, the control unit 8 turns off the power (not shown) when the internal timer counter elapses a prescribed time. When operating individual function keys such as mute and sound mode switching, an arbitrary key constituting the function key input unit 33 is pressed. When detecting the pressed position and detecting the mute key included in the function key input unit 33, the control unit 11 transmits a key code corresponding to the mute key. The control unit 8 receives the key code. For example, when the code of the mute key is detected, the control unit 8 controls the audio controller 6 to temporarily reduce the volume to zero. As a result, no sound is output from the speaker 7. Similarly, when performing AV input switching, the AV
Press the switch key. The control unit 11 detects the pressed position and transmits a key code corresponding to the pressed position. The control unit 8 receives the key code. When the code of the AV switch key is detected, the control unit 8 sets AVSW3 to T

When four asterisks are displayed in this manner, and when a function key in the DVD mode is subsequently operated, the function code of the DVD code is replaced with a numeric code and displayed as shown in FIG. 7B. This shows a case where the TOP MENU function code has been sent. On the other hand, when the numeric code is directly transmitted from the DVD-PLAYER dedicated remote controller (not shown), the disk control unit 42 determines the code from the numeric code table 44 and converts the function key code input into the numeric key code. At the same time as the replacement, it corresponds to the numeric key code from the dedicated remote controller, and the processing of FIG. 7A is omitted, and the display of FIG. 7B is immediately performed. As a result, reading of the function key code at the time of the DVD mode,
Performs direct reading of numeric key codes smoothly. In this way, even when a numeric key input for replacing a function key code and a numeric key code input from another remote controller are mixed at the time of numeric input setting, numeric input can be performed irrespective of which code is entered. It should be noted that the function key code reading process is automatically canceled by the disk controller 41 when the predetermined number of input digits is reached, thereby automatically returning to the function key code reading. When it becomes necessary to replace the numeric key code, the numeric input code key 88 may be operated each time.
