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.
Claims20
A method comprising:
- initiating an encoding of a video sequence to produce an encoded video sequence, wherein the encoding of the video sequence includes:
- partitioning a coding block into two or more prediction blocks based on a partitioning mode;
- encoding the partitioning mode for the coding block;
- and
- encoding a split transform flag in a transform tree rooted at the coding block, wherein the split transform flag indicates that a size of a transform block associated with the coding block is equal to a size of the coding block, and wherein the transform tree is independent of the partitioning mode for the coding block;
- distributing the encoded video sequence over a communication channel;
- and
- causing a decoding of the encoded video sequence in a decoder device, wherein the causing comprises receiving the encoded video sequence by the decoder device.
