Abstract
An image decoding method according to the present invention comprises the steps of: referring to a first flag for indicating whether intra block-based delta pulse code modulation (BDPCM) signaled through a sequence parameter set is permitted, so as to determine whether a second flag for indicating whether the intra BDPCM is applied to a current block is parsed; determining whether the intra BDPCM is applied to the current block on the basis of the second flag; determining an intra BDPCM mode of the current block when it is determined that the intra BDPCM is applied to the current block; and acquiring a residual sample of the current block on the basis of the intra BDPCM mode.

1-10. (canceled)
A video decoding method comprising:
- parsing, from a bitstream representing video content, first index information for a coding block, wherein the first index information signals a first triangle merge candidate from among a plurality of candidate triangle merge candidates;
- decoding, from the bitstream, a first prediction unit of the coding block according to the first triangle merge candidate;
- determining, based on the first index information, a second triangle merge candidate from among the plurality of candidate triangle merge candidates, wherein determining the second triangle merge candidate comprises adding an offset value to the first index information;
- and
- decoding, from the bitstream, a second prediction unit of the coding block according to the second triangle merge candidate.
A system comprising:
- one or more processors;
- and
- one or more non-transitory computer readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- parsing, from a bitstream representing video content, first index information for a coding block, wherein the first index information signals a first triangle merge candidate from among a plurality of candidate triangle merge candidates;
- decoding, from the bitstream, a first prediction unit of the coding block according to the first triangle merge candidate;
- determining, based on the first index information, a second triangle merge candidate from among the plurality of candidate triangle merge candidates, wherein determining the second triangle merge candidate comprises adding an offset value to the first index information;
- and
- decoding, from the bitstream, a second prediction unit of the coding block according to the second triangle merge candidate.
One or more non-transitory computer readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- parsing, from a bitstream representing video content, first index information for a coding block, wherein the first index information signals a first triangle merge candidate from among a plurality of candidate triangle merge candidates;
- decoding, from the bitstream, a first prediction unit of the coding block according to the first triangle merge candidate;
- determining, based on the first index information, a second triangle merge candidate from among the plurality of candidate triangle merge candidates, wherein determining the second triangle merge candidate comprises adding an offset value to the first index information;
- and
- decoding, from the bitstream, a second prediction unit of the coding block according to the second triangle merge candidate.
