Abstract: 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.

Abstract: An apparatus and method for video coding and decoding with constrained PU partition are disclosed. In the High Efficient Video Coding (HEVC) system, rate-distortion function or other performance criterion usually is evaluated for various CU partition and PU partition during the encoding process in order to select a configuration with best possible performance. The PU design in the current HEVC development results in some redundancy that causes rate-distortion function or other performance criterion repeatedly evaluated for same PU configuration. Accordingly, constrained PU partition is developed to eliminate or reduce the redundancy in processing. Furthermore, necessary syntax to convey the information related to constrained PU partition between an encoder and a decoder is developed. Systems embodying the present invention has been shown to result in sizeable reduction in encoding and decoding time while the performance in terms of RD-rate remains approximately the same or slightly higher than a conventional HEVC system.

Abstract: 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.
