Playback control apparatus

摘要

In a display device (12) used together with a playback apparatus (9) such as an optical disk, a control is provided responding to a playback signal from an playback apparatus (9) in order to prevent burn-out of CRT phosphor or deterioration of phosphor. A first controller (1) controls the playback apparatus (9), and a second controller (2) controls the display device (12), and those two controllers communicate with each other, thereby recognizing an operation status and a display status. Thus those two controllers control circuits and apparatus including a video control circuit (8) which controls a contrast, whereby optimizing a display on a screen, and control status (6) of an audio output, a power supply controller (7), and a playback apparatus controller.
