ABSTRACT:
A CDP-incorporated television receiver is provided which includes a CD reproducer, a CDG processor, a CDV processor, and a CD-OK processor. The CD reproducer reads data from an optical disk, and the CDG, CDV, and CD-OK processors input such data and respectively produce corresponding RGB, synchronization, and other signals, which respectively correspond to CD-graphics, CD-video, and CD-OK. A CD controller also receives a data signal from said CD reproducer, and determines the type of compact disk currently being reproduced by the CD reproducer based on the data signal. As a result, the CD controller produces a selection signal corresponding to the type of compact disk and outputs the selection signal to a switching matrix. The switching matrix selectively outputs one group of RGB, synchronization, and other signals based on the selection signal to an encoder, and the encoder converts the selected RGB signal into a CD video signal. The CDP-incorporated television receiver also contains a TV receiver which receives a TV video signal and a TV controller which generates a selection signal in accordance with a CD/TV selection command. A switching circuit selectively outputs, in response to the selection signal, either the CD video signal output from the encoder or the TV video signal output from the TV receiver as a selected video signal. Finally, a video processor processes the selected video signal and displays the selected video signal.
