摘要： A block based sampling (BBS) encoding system to process an incoming video signal into a compressed video bitstream. The BBS encoding system includes a processor to determine anchor blocks in a picture from the incoming video signal. The processor is also to encode the anchor blocks in the picture, and may also encode interpolated blocks in the picture using at least one of the encoded anchor blocks. There is also a block based sampling (BBS) decoding system to decode pictures from an incoming compressed video bitstream. The BBS decoding system includes a processor to receive the incoming compressed video bitstream including anchor block coding decisions about anchor blocks in a pattern in a picture, and decode the received anchor block coding decisions to form the anchor blocks in the pattern in the picture.

摘要： There is a coding including-preparing coding units based on source pictures. The coding units are associated with largest coding tree units (LCTUs) which are polygons of source pictures. A tree format is utilized in processing the LCTUs into coding units. The preparing includes calculating an efficiency measure associated with a source picture position in a coordinate system based on fitting the coordinate system and the source picture with respect to each other. The preparing includes determining the source picture position based on a coding efficiency goal. The preparing includes determining padding areas. The source picture and padding areas are divided into LCTUs based on the coordinate system and the determined source picture position. The LCTUs are partitioned into coding units based on the tree format and a homogeneity rule. There is also a decoding including processing video compression data which is generated based on the coding units.

摘要： A 3D video coding apparatus and method which selectively codes video data from a plurality of video sources to include depth information. Coding may be performed by combining depth information with view information, such as RGB, YCrCb, or YUV, and coded together with the view information as, RGBD, YCrCbD or YUVD. An apparatus may selectively code the depth information based on a depth format flag to include no depth information (e.g. a 2D format) or include depth information as a chroma channel. The depth information may be coded separately or together with YCrCb based on a coding cost or rate distortion estimate to encode the video information to obtain the highest quality.

摘要： A method and system of encoding and decoding possible outcomes of events of digital video content. The digital video content comprises a stream of pictures, slices, or macroblocks which can each be intra, predicted or bi-predicted pictures, slices, or macroblocks. The method comprises generating and decoding a stream of bits that represent the outcomes using entries in a lookup table that are periodically rearranged based on historical probabilities of the possible outcomes. The historical probabilities of the possible outcomes are computed by counting occurrences of each of the encoded and decoded outcomes in the stream of pictures, slices, or macroblocks. The periodic rearrangement of the entries in the lookup tables used by the encoder and the decoder is synchronized so that the stream of bits representing the encoded outcomes can be correctly decoded.

摘要： Methods and apparatus are provided to produce a plurality of different rate output bitstreams from a common input bit stream. Overhead data (30) is extracted from the input bit stream. The input bit stream is partially decoded (62). Thereafter, the at least partially decoded bit stream is re-encoded at different rates (64A, 64B... 64N), to produce multiple re-encoded bit streams (STREAM 1, STREAM 2... STREAM N) having different rates. The overhead data (30) is combined (60) with each re-encoded bit stream, thereby providing multiple versions of said encoded bit stream at different rates.

摘要： A system is provided for creating binary codewords for transform coefficients used for relating transform units (TUs) divided into coding units (CUs) in a High Efficiency Video Coding (HEVC) system. The system provides binarization of the codewords and removes unnecessary operations to reduce system complexity and increase compression performance. The system generates transform coefficients that relate the TUs and begins by providing a parameter variable (cRiceParam) set to an initial value of zero. Significant transform coefficients are converted into binary codewords based on the current value of the parameter variable, and the parameter variable is then updated with a new current value after each transform coefficient has been converted. Updating can be provided with reference to table values or the values can be provided from combination logic.
