Abstract: A method of binarizing an input symbol using a hybrid Truncated Rice/k-th order exp-Golomb binarization scheme with a Rice Parameter includes: determining a threshold; comparing the input symbol with the threshold; constructing a codeword using a Truncated Rice (TR) binarization process for the input symbol when a comparison result belongs to a first type of comparison result; and constructing a codeword with an initial prefix and a suffix for the input symbol when the comparison result belongs to a second type of comparison result; wherein the suffix is constructed using an exp-Golomb binarization process.

Abstract: A method and apparatus for video encoding to generate a partitioned bitstream without buffering transform coefficient and/or prediction data for subsequent coding units are disclosed. An encoder incorporating an embodiment according to the present invention receives first video parameters associated with a current coding unit, wherein no first video parameters associated with subsequent coding units are buffered. The encoder then encodes the first video parameters to generate a current first compressed data corresponding to the current coding unit. A first memory address in the first logic unit is determined and the encoder provides the current first compressed data at the first memory address in the first logic unit.
