CPC H04N 19/573 (2014.11) [H04N 19/105 (2014.11); H04N 19/136 (2014.11); H04N 19/436 (2014.11); H04N 19/52 (2014.11); H04N 19/593 (2014.11); H04N 19/61 (2014.11)] | 3 Claims |
1. A video decoding method, comprising:
deriving information for block availability of a neighboring block for a current block;
deriving information for motion information availability of the neighboring block of the current block based on the information for block availability of the neighboring block;
constructing a merge candidate list for the current block based on the derived information for motion information availability of the neighboring block;
determining motion information of the current block based on the merge candidate list; and
obtaining prediction samples of the current block by using the motion information of the current block,
wherein the deriving information for block availability of the neighboring block comprises:
in a block availability derivation process of the neighboring block, deriving the information for block availability of the neighboring block based on whether slice information and tile information of the neighboring block are equal to slice information and tile information of the current block and whether a prediction mode of the neighboring block is an inter prediction mode or not; and
in a step of setting merge candidate from neighboring blocks of the current block, resetting the derived information for block availability of the neighboring block based on parallel merge level information indicating a size of a block in which a parallel merge processing is applicable,
wherein the information for block availability indicates whether a corresponding neighboring block is usable for an inter prediction of the current block and the information for motion information availability indicates whether motion information of the corresponding neighboring block is included in the merge candidate list.
