ABSTRACT:
A method for encoding a video signal including a video object plane(VOP) and object information thereof, the VOP having an object therein, divides the VOP into a plurality of blocks and detecting boundary blocks and object blocks, wherein each boundary block includes therein background pixels and object pixels and each object block includes therein object pixels only, the background and the object pixels representing pixels residing outside and inside the object, respectively. Then the object information is converted into a set of object symbols and each object symbol is added to a background pixel included in a boundary block to thereby produce processing blocks, the processing blocks including the object blocks and one or more processed boundary blocks having therein the object symbols and the remaining unprocessed boundary blocks. The processing blocks are encoded to thereby generate an encoded video signal.
