Classification: CPC H | IPC H

Claim 0:
1. A video decoding method comprising:
obtaining a first triangular prediction unit and a second triangular prediction unit according to a coding block;
deriving a merge candidate list for the coding block;
deriving first motion information for the first triangular prediction unit from a merge candidate, and deriving second motion information for the second triangular prediction unit from another merge candidate; wherein the merge candidate is determined based on first index information and a first merge candidate in the merge candidate list, and the another merge candidate is determined based on second index information and a second merge candidate in the merge candidate list, and the second merge candidate is different from the first merge candidate; wherein the first index information and the second index information are decoded from a bitstream, and when a value of the second index information is equal to or greater than a value of the first index information, the value of the second index information is obtained by adding 1 to the value of the second index information; and
obtaining a prediction sample in the coding block based on the first motion information and the second motion information,
wherein a maximum number of merge candidates that the merge candidate list includes is determined based on whether the first triangular prediction unit and the second triangular prediction unit are obtained.
