Abstract: A system is provided for determining a binary codeword for a symbol representing a transform coefficient within transform units (TUs) that divide up coding units (CUs) in a High Efficiency Video Coding (HEVC) system. The system determines a truncated rice prefix and, when a parameter variable is greater than zero, determines a truncated rice suffix for the symbol. The system determines a main prefix either from the truncated rice prefix alone, or from a combination of the truncated rice prefix and the truncated rice suffix. When the main prefix is the same as a comparison string, the system also determines a main suffix. The system determines the final binary codeword for the symbol either from the main prefix alone, or from a combination of the main prefix and the main suffix.

Abstract: 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.
