Abstract
The present disclosure provides a method and apparatus for decoding video data. The method generally includes obtaining a video block of a bitstream, determining a rice parameter value associated with Golomb-Rice encoding for a current sample of the video block, wherein the rice parameter value can be adjusted based on a numerical range associated with sample values of the video block, and obtaining an entropy decoded value for the current sample of the video block based on the rice parameter value.
