Abstract:
1. A TV system including an optical disc apparatus comprising: a TV image receiver for displaying an image and for outputting sound from a video signal and audio signal of a TV signal; and an optical disc apparatus for playing back data in an optical disc and for supplying the signal thus played back to said TV image receiver, wherein said TV image receiver comprising: a TV signal selector for selectively accepting either a broadcast signal received by an antenna via a tuner or said playback signal from said optical disc apparatus and for outputting the signal thus selected as a TV signal; a video signal processing unit connected to said TV signal selector for dividing said TV signal into an audio signal and signals relating to the video image; an audio signal outputting unit connected to said video signal processing unit via an audio signal amplifier; a video signal outputting unit connected to said video signal processing unit via a video signal amplifier; and a TV controller for controlling said TV signal selector, said video signal processing unit, said audio signal amplifier and said video signal amplifier, wherein said optical disc apparatus comprising: a playback unit for reading data in said optical disc to output a playback signal; a playback signal processing unit connected to said playback unit for processing said playback signal to output it as a play-backed TV signal; an optical disc apparatus controller for controlling said playback unit and said playback signal processing unit; an optical disc apparatus memory allocated to said optical disc apparatus controller for storing still image data; and a signal superimposing unit for superimposing said signal of said still image data on said played-back TV signal to supply a composite TV signal to said TV image receiver, whereby when the time elapsed after a still image is displayed on said video signal outputting unit becomes greater than a predetermined time, said optical disc apparatus controller supplies an instruction of adjusting the brightness to said TV controller in said TV image receiver to reduce the brightness on the video signal outputting unit.
