摘要： A video transcoding method is provided for transcoding a first signal stream compressed by a first coding scheme to a second signal stream compressed by a second coding scheme. The method employs an adaptive frame rate and a joint temporal-spatial rate control technique, such that the overall quality of compressed MPEG video can be significantly enhanced when the transcoding is controlled in the joint temporal (picture or frame rate) and spatial (quantization) domains. One embodiment considers transcoding from high bit rate video with larger image size (e.g. 4CIF/4SIF, CIF) coded by one coding technique, e.g., MPEG-2 to a lower bit rate video with smaller image size (e.g. CIF, QCIF) coded by the same or another coding technique, e.g., MPEG-4.

摘要： A method and system process transform blocks according to quantization matrices in a video coding system. Embodiments of the present invention derive one or more derived quantization matrices from one or more initial quantization matrices or from one previously derived quantization matrix. In one embodiment, the initial quantization matrices include a 4×4 and 8×8 quantization matrices, which can be either default or user-defined. All quantization matrices larger than 8×8 can be derived from the 4×4 and 8×8 initial quantization matrices. Non-square quantization matrices can be derived from at least one initial square quantization matrix or at least one derived square quantization matrix. Individual initial quantization matrices may be used to derive respective larger quantization matrices. Furthermore, the individual initial quantization matrices may be derived from larger quantization matrices designed for corresponding transform sizes. Syntax design also enables the quantization matrix representation.

摘要： A method and apparatus for video data processing for video in YUV422 or YUV 444 formats are disclosed. In one embodiment, for a 2N×2N luma coding unit (CU) in YUV422 format, the transform process partitions residue data corresponding to the 2N×2N luma CU and the N×2N chroma CU into square luma and chroma transform units (TUs). The residue data associated with the luma and the chroma CUs are generated by applying prediction process to the luma CU and the chroma CU. The transform process is independent of prediction block size or prediction mode associated with the prediction process. In another embodiment, the prediction process splits the CU into two prediction blocks. Transform process is applied on the chroma residue data corresponding to the chroma CU to form one or more chroma TUs, wherein the transform process is dependent on CU size and prediction block size, or CU size and prediction mode.
