摘要： A method and apparatus for entropy coding and decoding for source symbols generated in a video coding system are disclosed. According to the present invention, a MSB (most significant bit) index and any refinement bit for the current symbol value are determined first. A first binary string is generated by binarizing a prefix part related to the MSB index of the current symbol value using a unary code or a truncated unary code. Also, a second binary string is generated by binarizing a suffix part corresponding to one or more refinement bits of the current symbol value using a fixed-length code or a truncated binary code if any refinement bit exists. The first binary string is coded using CABAC (context-adaptive binary arithmetic coding) and the second binary string is also coded using the CABAC if the second binary string exists.

摘要： A method and apparatus for signaling or parsing picture partition information are disclosed. The current picture is partitioned into one or more slices and one or more tiles according to the picture partition information. A control syntax is determined, where the control syntax is signaled from the video bitstream at the encoder side or parsed from the video bitstream at the decoder side unless the picture partition information indicates that a rectangular slice mode is selected, each sub picture is allowedto contain more than one rectangular slice, andthe current picture contains only one rectangular slice in the current picture. In-loop filtering is applied across slice boundaries if the picture partition information indicates multiple slices existing in the current picture and the control syntax indicates the in-loop filtering being enabled.

摘要： Methods and apparatus for video coding are disclosed. According to one method, a bitstream is generated or received, where the bitstream includes a first syntax and a second syntax. The first syntax is related to a target number of bits used to represent a set of third syntaxes and each third syntax specifies one subpicture ID for one subpicture in a set of subpictures. The second syntax is related to a total number of subpictures in the set of subpicture, where a first number that can be represented by the target number of bits is equal to or greater than the total number of subpictures. According to another method, the subpicture ID syntaxes have different values for different subpictures.

摘要： A video system that applies constraints on block partitioning is provided. The system receives a partitioning control parameter from a bitstream specifying a maximum block size for enabling ternary-tree split that is constrained to be 64 or smaller(1410). The system receives data from a bitstream for a block of pixels to be decoded as a current block of a current picture of a video(1420). The system splits the current block into one or more partitions recursively(1430), wherein ternary split is disallowed for a partition of the current block unless the partition is less than or equal to the maximum block size(1435). The system reconstructs the one or more partitions of the current block(1440).

摘要： A method for coding the coded block flags of individual transform blocks in a video coding system is provided. The method improves coding efficiency by jointly signaling the CBF values of Cb transform blocks and Cr transform blocks from a transform unit or coding unit. A single syntax element cbf_chroma is used to jointly code the CBF values of a pair of the collocated Cb and Cr transform blocks from a transform unit.

摘要： A method and apparatus for video coding using coding modes including a palette mode are disclosed. In one embodiment, the total number of palette indices in the current block is coded into a binary string using a TR (Truncated Rice) binarization process with the Rice parameter to generate a prefix part and using an EGk (k-th order Exp-Golomb) binary process to generate a suffix part for the binary string, or using the EGk binarization process with the Rice parameter (k). The suffix part is allowed to be empty. In another embodiment, a Rice parameter is determined. If the Rice parameter is equal to or greater than log-base-2 of current block size, the variable related to a total number of palette indices in the current block of video data is binarized into a binary string using a fixed-length code with bit length equal to log-base-2 of current block size.

摘要： A method of modified SAO (sample-adaptive offset) processing for a reconstructed picture in a video coding system to improve the performance is disclosed. In one example, a SAO-sign threshold is introduced to determine the sign of the difference between a current reconstructed pixel and a neighboring reconstructed pixel. A range of difference values greater than the negative SAO-sign threshold and smaller than the positive SAO-sign threshold is assigned to have a sign value of 0. In another example, the SAO-offset value is derived by multiplying the SAO-offset sign with a result from applying left shift by the SAO-bit-shift value to the absolute SAO-offset value. In yet another example, the absolute SAO-offset value is coded by truncated Rice (TR) codes and a maximum TR value is indicated by a syntax element.

摘要： A method and apparatus for coding video data using Inter prediction mode or Merge mode in a video coding system are disclosed, where the video data is configured into a Base Layer (BL) and an Enhancement Layer (EL), and the EL has higher spatial resolution or better video quality than the BL. In one embodiment, at least one information piece of motion information associated with one or more BL blocks in the BL is identified. A motion vector prediction (MVP) candidate list or a Merge candidate list for the selected block in the EL is then determined, where said at least one information piece associated with said one or more BL blocks in the BL is included in the MVP candidate list or the Merge candidate list. The input data associated with the selected block is coded or decoded using the MVP candidate list or the Merge candidate list.
