ABSTRACT:
In video/audio compression, a video signal is separated into luminance and a color difference. The color difference is partially subsampled. An interframe difference is compression-coded by an encoding unit. At that time, particular subsampling information corresponding to a designated reproducing rate is extracted from subsampling information. The particular subsampling information is inserted into compressed video data. On the other hand, in video/audio reproduction, the color difference of the video, which has partially been subsampled, are interpolated by a decoding unit with reference to the subsampling information inserted into the compressed video data.
