Abstract
An apparatus for generating compressed signals, which can serve to record data with high efficiency, to manage data easily, to reproduce programs in a special manner, to search for data at high speed, and to achieve accurate image-speech synchronization. The apparatus comprises a video-data grouping device for processing video data into groups, each consisting of a predetermined number of video data items corresponding to image frames; a video-data compressing device for compressing and encoding the video data items of each group; an audio-data grouping device for processing audio data corresponding to the video data into groups, each group consisting of audio data items; an audio-data compressing device for compressing and encoding the audio data items of each group; a sub-video data grouping device for processing sub-video data into groups, each group consisting of sub-video data items; a sub-video data compressing device for compressing and encoding the sub-video data items of each group; a formatter for combining the groups of compressed video data items, the groups of compressed audio data items and the groups of compressed sub-video data items thereby generating a data unit.
