Abstract
A video signal compressing method and a video signal compressing apparatus for compressing a video signal for a system in which for a synchronism between a plurality of compressed signals must be maintained. A presentation time stamp and/or a decode time stamp are multiplexed in a stream for transmission in which a video signal is compressed to generate a compressed signal. The following are generated as access unit information (AUI) for use in multiplexing the compressed data of the video signal: a picture size value, a picture type value, a repeat first field value, and a flag indicating the occurrence of a big picture.
