摘要: An apparatus for receiving motion pictures is disclosed. The present invention reduces an external memory in an MPEG-2 decoding chip, which is a standard device in the field of digital video transmission. Particularly, a data processing structure is disclosed for compressing video-decoded data in an ADPCM method and storing the same in an external memory so as to ease compensation for motion in a macro-block unit of the MPEG-2 standard device as well as to maintain motion pictures of high definition.
