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.

摘要： A system is provided for creating level parameter updating codewords for transform coefficients used for relating transform units (TUs) that divide up 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. The parameter variable is then converted into a binary codeword based on the current value of the parameter variable and the value of a symbol and then updated with a new current value after each symbol has been converted. Updating can be provided with reference to table values or the values can be provided from combination logic.

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.
