摘要： A method and apparatus for deblocking of reconstructed video are disclosed. In one embodiment, the method divides a block boundary into two sub-boundaries and separates lines or column across the sub-boundaries into two groups. The deblocking filter decision for each group is determined based on the lines or columns in the respective group. In another embodiment, the method divides block edges of blocks in the LCUs into two edge groups, where the first edge group corresponds to horizontal block edges between two LCUs and the second edge group corresponds to remaining block edges not included in the first edge group. The number of lines processed by a vertical filter in the first edge group is less than the number of lines processed by a vertical filter in the second edge group. Accordingly, a system embodying the present invention has reduced storage requirement.

摘要： A method and apparatus for determining a motion vector predictor (MVP) or a MVP candidate based on a MVP set are disclosed. In video coding systems, the spatial and temporal redundancy is exploited using spatial and temporal prediction to reduce the video data to be transmitted or stored. Motion vector prediction has been used to further conserve the bitrate associated with motion vector coding. Motion vector prediction technique being developed for the current high efficiency video coding (HEVC) only uses a MVP candidate set including spatial MVP candidates and a temporal candidate corresponding to the co-located block. In the current disclosure, the spatial and temporal motion vector predictor set is extended to include at least one spatially neighboring block associated with list 0 reference pictures and list 1 reference pictures, and co-located block and its neighboring block associated with list 0 reference pictures and list 1 reference pictures.

The chroma intra predictor is derived from reconstructed luma pixels of a current luma block using a model with parameters.

The inter prediction block performs prediction on a current frame, the transform and quantization block performs transform and quantization processes on prediction residues, and the reconstruction loop reconstructs the current frame to generate the restored reconstructed samples. The adaptive restoration block performs restoration on processed data by considering a plurality of candidate restoration methods, selects one of the candidate restoration methods as a final restoration method, and generates adaptive restoration information corresponding to the final restoration method.

摘要： A method and apparatus for deriving a temporal motion vector predictor (MVP) are disclosed. The MVP is derived for a current block of a current picture in Inter, or Merge, or Skip mode based on co-located reference blocks of a co-located block. The co-located reference blocks comprise an above-left reference block of the bottom-right neighboring block of the co-located block. The reference motion vectors associated with the co-located reference blocks are received and used to derive the temporal MVP. Various configurations of co-located reference blocks can be used to practice the present invention. If the MVP cannot be found based on the above-left reference block, search for the MVP can be continued based on other co-located reference blocks. When an MVP is found, the MVP is checked against the previously found MVP. If the MVP is the same as the previously found MVP, the search for MVP continues.
