Techniques for constraint flag signaling for range extension with residual rice coding extension
Abstract:
Aspects of the disclosure provide methods and apparatuses for video data processing. In some examples, an apparatus for video data processing includes processing circuitry. For example, the processing circuitry determines a first syntax element for coding control in a first scope of coded video data in a bitstream. The first syntax element is associated with a second coding tool that is alternative to a first coding tool for Rice parameter derivation in a residual coding. In response to the first syntax element being a first value indicative of disabling of the second coding tool in the first scope, the processing circuitry decodes the first scope of coded video data that includes one or more second scopes of coded video data without invoking the second coding tool.
