Patent attributes
Combining intra-frame and inter-frame prediction is described. A first combined prediction block for a first block is formed by combining weighted pixel values of a first inter prediction block and a first intra prediction block. A second combined prediction block is formed by combining pixel values of a second intra prediction block and a second inter prediction block. The first intra prediction block and the second intra prediction block have pixel dimensions corresponding to the first block. The pixel values of the second inter prediction block have pixel locations corresponding to a first partitioned area formed by an oblique line extending across the first block, and the pixel values of the second intra prediction block used in forming the second combined prediction block have pixel locations corresponding to a second partitioned area formed by the oblique line. One of the combined prediction blocks is selected to encode the first block.
