Patent ID: 7391962

Claim:
An optical recording/reproducing apparatus for recording and reproducing data to and from an optical medium, comprising: a video decoder which converts an analog video signal into a converted digital video signal; an audio and video (A/V) codec comprising: a pre-compression processing unit which separates luminance and color components from the converted digital video signal, an encoder which compresses the digital video signal having the separated luminance and color components in a predetermined compression format, and a decoder which decodes the compressed digital video signal; and a memory used for a storage space as the A/V codec separates, compresses and decodes the converted video signal, wherein the pre-compression processing unit comprises: a 3-dimensional(3D) Y/C separator which compares pixel by pixel the predetermined number of consecutive frames among frames of the converted digital video signal and separates the luminance and color components based on the comparison; and a time base corrector (TBC) which stabilizes synchronization of the digital video signal having the separated luminance and color components.
