Abstract
Decoding of a merge-predicted block is carried out, for triangular partitions of the block, using a combination of inter-prediction and intra-prediction. The combination of inter-prediction and intra-prediction to be used is signalled on a received bitstream. Combination may be algorithmic, for example arithmetic.
Claims16
A decoder for decoding a block on a bitstream, the decoder being operable to extract triangular prediction configuration information from the bitstream, on the basis of which the decoder is operable to generate a prediction comprising two parts corresponding to a triangular partition of the block, at least one of the parts being predicted using information obtained by intra-prediction.
A method of decoding a block on a bitstream, comprising extracting triangular prediction configuration information from the bitstream, and generating a prediction comprising two parts corresponding to a triangular partition of the block, at least one of the parts being predicted using information obtained by intra-prediction.
An encoder operable to encode a block for dispatch on a bitstream, the encoder being operable to generate a prediction comprising two parts corresponding to a triangular partition of the block, at least one of the parts being predicted using information obtained by intra-prediction, the encoder being operable to place on the bitstream triangular prediction configuration information for used by a decoder in producing a corresponding prediction of the block.
