Abstract:
In a method of video encoding in an encoder, a determination is made as to whether to encode a first scope of coded video data in a bitstream with a second coding tool. The second coding tool is an alternative coding tool to a first coding tool for Rice parameter derivation in residual coding. In response to a determination that the first scope of coded video data is not encoded with the second coding tool, a first syntax element is determined as a first value indicating that the second coding tool is disabled in the first scope of the coded video data and a video bitstream of the first scope of coded video data is encoded without invoking the second coding tool. The first syntax element is associated with the second coding tool.
