摘要： In various embodiments, a significance map of a matrix of video data coefficients is encoded or decoded using context-based adaptive binary arithmetic coding (CABAC). The significance map scanned line-by-line along a scanning pattern. Each line may be a vertical, horizontal, or diagonal section of the scanning pattern. Context models for each element processed in a particular line are chosen based on values of neighboring elements that are not in the line. The neighboring elements may be limited to those contained within one or two other scanning lines. Avoiding reliance on neighbors that are in the same scanning line facilitates parallel processing.

摘要： Embodiments for high efficiency low complexity interpolation filters for High Efficiency Video Coding are disclosed herein, specifically novel techniques for a video compression system. In order to estimate and compensate sub-pel displacements, the image signal on these sub-pel positions is generated by an interpolation process. In HEVC, sub-pel pixel interpolation is performed using filters. Generally, the filter may have 8 taps to determine the sub-pel pixel values for sub-pel pixel positions, such as half-pel and quarter-pel positions. The taps of an interpolation filter weight the integer pixels with coefficient values to generate the sub-pel signals. Different coefficients may produce different compression performance in signal distortion and noise.

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.
