METHOD AND APPARATUS FOR PROCESSING VIDEO SIGNALS USING BOUNDARY INTRA CODING

摘要

A boundary intra coding flag is obtained according to a current macroblock type. When the boundary intra coding flag indicates that the current macroblock is coded in an intra prediction mode using boundary intra coding, boundary coding information is obtained, and a boundary in the current macroblock is induced based on the boundary coding information. Therefore, the regions divided by the boundary can be coded in the intra prediction mode. The accuracy of a predicted pixel value can be improved by performing the intra prediction for the regions divided by the boundary. Accordingly, the residual data transmitted to a decoder can be reduced.
