Abstract
Methods, apparatuses, and non-transitory computer-readable storage mediums are provided for video coding. In response to a transform skip is disabled, an encoder does not signal a syntax element related to a rice parameter for transform skip residual coding. The encoder may control of a syntax element a presence sps_ts_residual_coding_rice_present_in_sh_flag based on a transform-skip enable flag sps_transform_skip_enabled_flag.
Claims20
A method for video encoding, comprising:
- when transform skip is disabled, an encoder not signaling a syntax element related to a rice parameter for transform skip residual coding;
- and
- adopting a flag of transform skip, sps_transform_skip_enabled_flag, to condition a presence of sps_ts_residual_coding_rice_present_in_sh_flag.
A method for video decoding, comprising:
- in response to determining that transform skip is disabled, not receiving, by a decoder, a control flag for indicating whether a syntax element to be used for determining a rice parameter for transform skip residual coding is present or not.
A non-transitory computer-readable storage medium storing a bitstream generated by an encoding method, wherein the encoding method comprises:
- when transform skip is disabled, an encoder not signaling a syntax element related to a rice parameter for transform skip residual coding;
- and
- adopting a flag of transform skip, sps_transform_skip_enabled_flag, to condition a presence of sps_ts_residual_coding_rice_present_in_sh_flag.
