SIGNAL PROCESSING APPARATUS FOR VIDEO CD PLAYER

摘要

a means(22) outputting a digital voice signal and a sub code or a compressed sign data by processing RF signal read by an optical pickup(21) from a disk such as a compact disk graphic and a video compact disk; a control means(23) switching and controlling a signal processing path for the above disk according to the sub code or the compression sign data; a first switching means(25) switching the voice signal processing path in order to perform noise filtering, analog conversion and amplification output; a second switching means(28) switching and outputting character information for the play of the sub code and the disk; a third switching means(31) switching and outputting image data of a CDG decoding means(29) and image data of a MPEG decoding means(24); and a means(30) which enables image data of each disk to be converted a NTSC composite image signal through a RGB encoder(32) and an image output part(33) and to be outputted by amplification by controlling the switching operation of the third switching means(31).
