Techniques for constraint flag signaling for range extension with residual rice coding extension

An apparatus for video encoding, comprising

• processing circuitry configured to:
• determining whether to encode a first scope of coded video data in a bitstream with a second coding tool, the second coding tool being an alternative coding tool to a first coding tool for Rice parameter derivation in residual coding;
• and
• in response to a determination that the first scope of coded video data is not encoded with the second coding tool,
• determining a first syntax element as a first value indicating that the second coding tool is disabled in the first scope of the coded video data, the first syntax element being associated with the second coding tool, and
• encoding a video bitstream of the first scope of coded video data without invoking the second coding tool.

A non-transitory computer-readable storage medium storing instructions which when executed by at least one processor cause the at least one processor to perform:

• determining whether to encode a first scope of coded video data in a bitstream with a second coding tool, the second coding tool being an alternative coding tool to a first coding tool for Rice parameter derivation in residual coding;
• and
• in response to a determination that the first scope of coded video data is not encoded with the second coding tool,
• determining a first syntax element as a first value indicating that the second coding tool is disabled in the first scope of the coded video data, the first syntax element being associated with the second coding tool, and
• encoding a video bitstream of the first scope of coded video data without invoking the second coding tool.
