摘要： The present invention improves residue prediction by using MI even when the base layer MB is encoded in intra mode such as copying intra 4×4 mode of one 4×4 block in the base layer to multiple neighboring 4×4 blocks in the enhancement layer if the base layer resolution is lower than the enhancement layer resolution, using the intra 4×4 mode as intra 8×8 mode if the base layer resolution is lower than the enhancement layer resolution and the base layer resolution is half of the enhancement layer resolution in both dimensions, carrying out direct calculation of the base layer prediction residue used in RP, clipping of prediction residue for reducing memory requirement and tunneling of prediction residue in BLTP mode; and conditional coding of RP flag to save flag bits and reduce implementation complexity

摘要： A scalable video coding method and apparatus for coding a video sequence, wherein the coefficients in the enhancement layer is classified as belonging to a significant pass when the corresponding coefficient in the base layer is zero, and classified as belonging to a refinement pass when the corresponding coefficient in the base layer is non-zero. For coefficients classified as belonging to the significance pass, an indication is coded to indicate whether the coefficient is zero or non-zero, and if the coefficient is non-zero, coding an indication of the sign of the coefficient. A last_significant_coeff_flag is used to indicate the coding of remaining coefficients in the scanning order can be skipped. For coefficients classified as belonging to the refinement pass, a value to refine the magnitude of the corresponding coefficient in the base layer is coded, and if the coefficient is non-zero, a sign bit may be coded.

摘要： This disclosure describes techniques for coding transform coefficients for a block of video data. According to some aspects of this disclosure, a coder (e.g., an encoder or decoder) may map between a code number cn and level_ID and run values associated with a first transform coefficient of the block of video data according to a first technique (e.g., a structured mapping), and map between a code number cn and level_ID and run values associated with a second coefficient of the block using a second technique. According to other aspects of this disclosure, the coder may map between a code number cn and level_ID and run syntax elements using different mathematical relationships, depending on a determined value of the code number cn or the level_ID syntax element. For example, the coder may access a mapping table of a plurality of mapping tables differently, dependent on the determined value.

摘要： A computing device determines whether a prediction unit (PU) in a B slice is restricted to uni-directional inter prediction. In addition, the computing device generates a merge candidate list for the PU and determines a selected merge candidate in the merge candidate list. If the PU is restricted to uni-directional inter prediction, the computing device generates a predictive video block for the PU based on no more than one reference block associated with motion information specified by the selected merge candidate. If the PU is not restricted to uni-directional inter prediction, the computing device generates the predictive video block for the PU based on one or more reference blocks associated with the motion information specified by the selected merge candidate.

摘要： For a block of video data, a video encoder can signal to a video decoder, using a context-based adaptive binary arithmetic coding (CABAC) process, a selected intra-prediction mode using a codeword that is mapped to a modified intra-prediction mode index. The video decoder can perform a context-based adaptive binary arithmetic coding (CABAC) process to determine the codeword signaled by the video encoder, determine the modified intra-prediction mode index corresponding to the codeword, determine most probable modes based on a context, map the modified intra-prediction mode index to an intra-prediction mode index by comparing the modified intra-prediction mode index to the mode indexes of the most probable modes, and determine the selected intra-prediction mode used to encode the block of video data based on the intra-prediction mode index.

摘要： A video encoder can maintain, by generating, storing, adjusting, altering, and/or updating, one or more variable length coding (VLC) tables that represent a mapping of prediction modes to codewords. One or more codewords representing a selected prediction mode can be communicated to the decoder for a CU of a frame. The decoder maintains one or more VLC tables that match the VLC tables maintained by the video encoder. Thus, based on the one or more codewords received from the video encoder, the video decoder can determine the prediction mode used to encode a CU.

摘要： This disclosure describes techniques for coding transform coefficients for a block of video data. According to some aspects of this disclosure, a video coder (e.g., encoder, decoder) may code a first coefficient of a leaf-level unit of video data using a run encoding mode. The coder may code a second coefficient of the leaf-level unit of video data using a level encoding mode. After coding at least one coefficient using the level coding mode, the coder may use the run coding mode to code a third other coefficient of the leaf-level unit of video data. According to other aspects, an encoder may signal, to a decoder, at least one indication of a transition between level and run coding modes. According to still other aspects, a coder may automatically determine when to transition between the level and run coding modes.
