摘要：Methods and apparatus are provided for efficient video encoding and decoding of intra prediction mode. An apparatus includes a video encoder for encoding picture data for at least a block in a picture by determining a spatial pattern for a decoded intra prediction mode residue used to reconstruct the picture at the video encoder. The decoded intra prediction mode residue is obtained by inverse quantizing and inverse transforming a transformed and quantized difference between an original version of the block and at least one reference block. The spatial pattern is used to determine an intra prediction mode for encoding the block.
