Abstract
Using fewer bits to indicate the prediction mode used for encoding some of the non-frame-edge blocks of a frame. In an embodiment, fewer bits are used in case of boundary blocks of a slice, or slice group. In another embodiment, fewer bits are used when adjacent blocks are encoded using inter-frame coding or switchable intra-frame coding and such adjacent block cannot be used in predicting a block.
