Abstract
A synchronous compression system for compressing input video data and audio data with establishing synchronization therebetween, comprises video data compressing circuit for compressing each of first to nth blocks where n is an integer greater than or equal to two in order of the first block to the nth block, audio data compressing circuit for compressing input audio data for one frame, interruption control circuit for controlling to interrupt video data compression when video data compression process is delayed with respect to audio data compression process with reference to frame numbers of those currently compressed in the video data compressing circuit and the audio data compressing circuit.
