Abstract
A method and apparatus for a low complexity transform unit partitioning structure for High Efficiency Video Coding (HEVC). The method includes determining prediction unit size of a coding unit, and setting the size of transform unit size of Y, U and V according to the prediction unit size of the coding unit.
Claims15
A method comprising:
- decoding, by a decoder, a first split transform flag syntax element associated with a component coding block;
- decoding, by a decoder, a partitioning mode of the component coding block for a prediction block;
- partitioning the prediction block based on the decoded partitioning mode of the component coding block for the prediction block;
- determining whether to decode a first coding block flag based on the decoded partitioning mode of the component coding block for the prediction block;
- decoding, by the decoder, the first coding block flag associated with the coding block based on the decoding partitioning mode of the component coding block for the prediction block;
- splitting, by the decoder, the coding block into a first transform block when the first split transform flag syntax element specifies that the chrominance component coding block is split;
- and
- decoding, by the decoder, a coding block flag when the first chrominance component coding block flag specifies that the chrominance component coding block contains one or more non-zero transform coefficient levels.
