    摘要: In a video processing system, a method and system for applying transforms larger than 8×8 and non-rectangular transforms, and generating transform size syntax elements indicative of the transforms for video decoding are provided. The transform size syntax element may be generated by an encoder based on a prediction block size of a video block and the contents of the video block. Further, the transform size syntax element may be generated according to a set of rules to select from 4×4, 8×8, and larger transform sizes during an encoding process. A decoder may perform an inverse transform based on the transform size syntax element and the rules used by the encoder. The transform size syntax element may be transmitted to the decoder as part of the encoded video bitstream.

    摘要: This disclosure describes techniques for coding video data. In particular, this disclosure describes techniques for entropy coding of residual transform coefficients generated by a video coding process. In one example, a method selects a bin 2 context for coding a bin 2 level of one or more transform coefficients in the vector according to the entropy coding process. The method further codes the bin 2 level of one or more transform coefficients in the vector according to the selected bin 2 context. Selecting the bin 2 context comprises selecting the bin 2 context for a current transform coefficient in the vector based on the bin 2 level of one or more previously coded transform coefficients in the vector.

    摘要: This disclosure describes techniques for coding a video block based on an unclipped version of a motion vector predictor candidate. The techniques include determining a motion vector predictor candidate list including motion vector predictor candidates from neighboring video blocks without clipping the motion vector predictor candidates. More specifically, if one of the motion vector predictor candidates points to a prediction block located outside of a reference picture boundary relative to the current video block, the techniques allow an unclipped version of the motion vector predictor candidate to be included in the candidate list. The current video block is then coded based on a determined unclipped motion vector predictor candidate of the candidate list. Elimination of the motion vector predictor candidate clipping process reduces complexity at both the video encoder and the video decoder.

    摘要: For each prediction unit (PU) belonging to a coding unit (CU), a video coder generates a candidate list. The video coder generates the candidate list such that each candidate in the candidate list that is generated based on motion information of at least one other PU is generated without using motion information of any of the PUs belonging to the CU. After generating the candidate list for a PU, the video coder generates a predictive video block for the PU based on one or more reference blocks indicated by motion information of the PU. The motion information of the PU is determinable based on motion information indicated by a selected candidate in the candidate list for the PU.
