Optical recording/reproducing apparatus having a function of separating luminance and color components

摘要

An optical recording/reproducing apparatus comprising an audio and video (A/V) codec (230) having a function for separating luminance and color components. A video decoder (210) converts an analog video signal into a digital video signal; an AN codec having a pre-compression processing unit (220) separates luminance and color components from the converted digital video signal; an encoder (233) compresses the digital video signal having the separated luminance and color components into a predetermined compression format; and a decoder (236) decodes the digital video signal compressed in the predetermined compression format. A memory (240) provides a storage space as the AN codec carries out signal processing. Accordingly, the size and production cost of the video decoder may be reduced. <IMAGE>
