The video decoder which possesses the buffer in order it accompanies open-ended compression and at the same time remembers the standard frame data and to collect

摘要

The present invention relates to a video decoder having means for compressing reference frame data ( 6 ) using a scalable compression method. The video decoder further having buffer means ( 8 ) for intermediate storing of at least the vertical aperture (range) of motion vectors plus one row (slice) of macro blocks in lines of video per reference frame. Further it includes means for decompressing reference frame data ( 7 ) for enabling means for motion compensation ( 10 ) of said decoder to reconstruct vector predicted pictures and macro blocks utilizing said decompressed reference frame data. The present invention also relates to a method to be implemented by such a video decoder.
