ABSTRACT:
The on/off statuses of relays corresponding to information played back from an optical disk, for example, position information such as absolute time and track number, are stored in memory. When the absolute time or track number in the sub-code information decoded by the sub-code decode circuit is identical to the absolute time or track number stored in memory, the relays in the external device interface unit are switched to control the external devices connected to them. With this arrangement, external devices such as lights, slide projector, and illumination may easily be controlled in synchronization with optical disk playback information.
