Abstract:
A method and apparatus for video coding using coding modes including a palette mode are disclosed. In one embodiment, the total number of palette indices in the current block is coded into a binary string using a TR (Truncated Rice) binarization process with the Rice parameter to generate a prefix part and using an EGk (k-th order Exp-Golomb) binary process to generate a suffix part for the binary string, or using the EGk binarization process with the Rice parameter (k). The suffix part is allowed to be empty. In another embodiment, a Rice parameter is determined. If the Rice parameter is equal to or greater than log-base-2 of current block size, the variable related to a total number of palette indices in the current block of video data is binarized into a binary string using a fixed-length code with bit length equal to log-base-2 of current block size.

Claim (Index 10):
The method of  claim 7 , wherein the Rice parameter, cRiceParam, for the current block of the video data is derived according to cRiceParam=(a*(log 2(CUSize)>>1)+n+((MaxPaletteIndex+c)>>m)), and wherein log 2( ) is a log-base-2 function, CUSize corresponds to the block size of the current block of the video data, MaxPaletteIndex specifies a maximum possible value for any palette index in the current block of the video data, a is a non-zero integer, and n, c and m are integers.
