Abstract
A video signal decoding device comprises a processor which: decodes a general constraint information (GCI) syntax included in a bitstream of a video signal; and decodes the bitstream on the basis of the result of decoding the GCI syntax, wherein the GCI syntax includes a GCI syntax element for configuring the value of an SPS syntax element indicating whether it is possible to use a palette mode included in a sequence parameter set (SPS) raw byte sequence payload (RBSP) syntax.
Claims20
A video signal decoding device comprising a processor
- wherein the processor is configured to:
- decode a general constraint information (GCI) syntax included in a bitstream,
- decode the bitstream on the basis of a result of decoding the GCI syntax,
- wherein the GCI syntax includes a first GCI syntax element that constrains a value of a first sequence parameter set (SPS) syntax element included in a SPS raw byte sequence payload (RBSP) syntax, the first SPS syntax element indicates whether a palette mode is enabled, and
- wherein when a value of the first GCI syntax element is 1, the value of the first SPS syntax element is set to 0, which is a value indicating that the palette mode is disabled.
A video signal encoding device comprising a processor,
- wherein the processor is configured to:
- obtain a general constraint information (GCI) syntax,
- encode a bitstream including the GCI syntax,
- wherein the GCI syntax includes a first GCI syntax element that constrains a value of a first sequence parameter set (SPS) syntax element included in a SPS raw byte sequence payload (RBSP) syntax, the first SPS syntax element indicates whether a palette mode is enabled, and
- wherein when a value of the first GCI syntax element is 1, the value of the first SPS syntax element is set to 0, which is a value indicating that the palette mode is disabled.
A method of obtaining a bitstream, the method comprising:
- obtaining a first general constraint information (GCI) syntax element that constrains a value of a first sequence parameter set (SPS) syntax element included in a SPS raw byte sequence payload (RBSP) syntax, the first SPS syntax element indicates whether a palette mode is enabled,
- wherein the first GCI syntax element is included in general constraint information (GCI) syntax,
- wherein when a value of the first GCI syntax element is 1, the value of the first SPS syntax element is set to 0, which is a value indicating that the palette mode is disabled;
- and
- obtaining the bitstream including the first GCI syntax element and the first SPS syntax element by video signal encoding.
