摘要： A compressing method consisting of generating a predicted value for the pixel of the digitized image to be compressed based on the values of at least two neighboring pixels is provided. After calculating the difference between the predicted value and the current pixel value, a prediction error is defined by a one-on-one mapping on the difference obtained. According to an advantageous feature of the mapping relationship, the required number of bits for representing the prediction error is less than that required for the difference per se. Afterwards, a parameter K is generated which is in proportion to the difference between the neighboring pixels used in prediction. According to the respective values of the parameter K, the next step is to encode each prediction error by assigning a variable-length Rice code to the prediction error of each pixel. If the Rice code formatted for a prediction error is longer than a predetermined length, the Rice code is disregarded and replaced by predetermined length of leading "1" bits followed by the value of current pixel.

Encoding or decoding a current intra prediction mode is based on the multi-level MPM sets, where one syntax element of the syntax information to be generated or decoded respectively is associated with evaluating the current intra prediction mode using the first-level MPM set. A method and apparatus for chroma intra prediction mode encoding and decoding are also disclosed. The chroma intra prediction mode set includes a Luma-based chroma prediction Mode (LM), a Direct Mode (DM) and four other modes. The codeword set comprises variable-length codewords and fixed-length codewords, and the fixed-length codewords are longer than the variable-length codewords. The variable-length codewords are used for the DM and LM, and the fixed-length codewords are used for the four other modes.

摘要： A method and apparatus of line buffer reduction for context adaptive entropy processing are disclosed. The context formation for context adaptive entropy processing depends on block information associated with one or more neighboring blocks. When the neighboring block is on a different side of a region boundary from the current block, the block information is replaced by replacement block information to reduce or remove line buffer requirement for storing the block information of neighboring blocks on the other side of the region boundaries from the current block. The context adaptive entropy processing is CABAC encoding, CABAC decoding, CAVLC encoding, or CAVLC decoding.

摘要： An apparatus and method for deriving a motion vector predictor are disclosed. A search set comprising of multiple (spatial, or temporal) search MVs with priority is determined, wherein the search MVs for multiple neighboring reference block or one or more co-located reference blocks are configured into multiple search MV groups. In order to improve coding efficiency, embodiments according to the present invention, perform redundancy check every time after a search MV group is searched to determine whether an available search MV found. If an available search MV is found and the available search MV is not the same as a previously derived motion vector predictor (MVP), the available search MV is used as the MVP and the MVP derivation process terminates. Otherwise, the MVP derivation process moves to the next reference block. The search MV group can be configured to include different search MV(s) associated with reference blocks.

摘要： In a block-based motion compensated system, coding noises may arise due to lossy operations such as quantization. Deblocking is often used to alleviate visibility of coding artifacts by applying filtering across block boundaries adaptively. In the recent HEVC development, adaptive loop filtering (ALF) is being adopted to process deblocked reconstruction frames. Adaptive loop filtering is applied to reconstructed video data across multiple frames to reduce visibility of coding artifacts in the temporal domain. In a HEVC system, conventional ALF can be selectively turned ON or OFF for each block in a frame or a slice. The advanced ALF disclosed here allows a choice of multiple filter sets that can be applied to the reconstructed video data adaptively. Furthermore, the advanced ALF adopts a new unit for the filtering process to apply so that more flexible and/or localized processing can be provided. Furthermore, the advanced ALF allows a decoder to derive respective information for applying the filtering process without side information.
