Abstract
A video decoding method according to the present invention may comprise: a step for determining whether to divide a current block into a plurality of sub-blocks; a step for determining an intra prediction mode for the current block; and a step for performing intra prediction for each sub-block on the basis of the intra prediction mode, when the current block is divided into the plurality of sub-blocks.
Claims9
A method of encoding a video, the method comprising:
- determining a partitioning type of a coding block associated with the video, wherein the partitioning type is selected from among a plurality of partitioning type candidates;
- encoding index information representing the partitioning type;
- separating the coding block into a first prediction unit and a second prediction unit based on the determined partitioning type;
- determining motion information of each of the first prediction unit and the second prediction unit;
- determining prediction samples for the first prediction unit and the second prediction unit based on the motion information;
- and
- encoding the video based on the prediction samples.
A system comprising:
- one or more processors;
- and
- memory storing instructions that when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- determining a partitioning type of a coding block associated with a video, wherein the partitioning type is selected from among a plurality of partitioning type candidates;
- encoding index information representing the partitioning type;
- separating the coding block into a first prediction unit and a second prediction unit based on the determined partitioning type;
- determining motion information of each of the first prediction unit and the second prediction unit;
- determining prediction samples for the first prediction unit and the second prediction unit based on the motion information;
- and
- encoding the video based on the prediction samples.
One or more non-transitory, computer-readable storage media having instructions stored thereon, that when executed by one or more processors, cause the one or more processors to perform operations comprising:
- determining a partitioning type of a coding block associated with a video, wherein the partitioning type is selected from among a plurality of partitioning type candidates;
- encoding index information representing the partitioning type;
- separating the coding block into a first prediction unit and a second prediction unit based on the determined partitioning type;
- determining motion information of each of the first prediction unit and the second prediction unit;
- determining prediction samples for the first prediction unit and the second prediction unit based on the motion information;
- and
- encoding the video based on the prediction samples.
