Abstract
The present invention is related to processing a video signal. A method for decoding a video according to the present invention may comprise checking a merge coding unit which is generated by merging a plurality of coding units neighboring each other based on an encoded syntax element, and decoding the checked merge coding unit, wherein a same motion vector is shared in the merge coding unit.
Claims8
A method of decoding an image, comprising:
- dividing, based on a tree-based division, a coding block to determine a current block, the tree-based division including at least one of a quad division, a binary division, or a triple division;
- and
- decoding the current block based on intra prediction or inter prediction,
- wherein the triple division is a division type of dividing a first coding block into three second coding blocks,
- wherein one of the three second coding blocks has a size greater than a size of the other two of the three second coding blocks,
- wherein the largest second coding block is located between the other two of the three second coding blocks,
- wherein, with respect to the binary division for the at least one of the three second coding blocks, it is restricted so as not to be divided in a same division direction as a division direction of the triple division for the first coding block, and
- wherein the restriction is applied only to the largest second coding block among the three second coding blocks.

A method of encoding an image, comprising:
- dividing, based on a tree-based division, a coding block to determine a current block, the tree-based division including at least one of a quad division, a binary division, or a triple division;
- and
- encoding the current block based on intra prediction or inter prediction,
- wherein the triple division is a division type of dividing a first coding block into three second coding blocks,
- wherein one of the three second coding blocks has a size greater than a size of the other two of the three second coding blocks,
- wherein the largest second coding block is located between the other two of the three second coding blocks,
- wherein, with respect to the binary division for the at least one of the three second coding blocks, it is restricted so as not to be divided in a same division direction as a division direction of the triple division for the first coding block, and
- wherein the restriction is applied only to the largest second coding block among the three second coding blocks.
5 more elements
A non-transitory computer-readable medium for storing data associated with an image signal, comprising:
- a data stream stored in the non-transitory computer-readable medium, the data stream being encoded by an encoding method comprising:
- dividing, based on a tree-based division, a coding block to determine a current block, the tree-based division including at least one of a quad division, a binary division, or a triple division;
- and
- encoding the current block based on intra prediction or inter prediction,
- wherein the triple division is a division type of dividing a first coding block into three second coding blocks,
- wherein one of the three second coding blocks has a size greater than a size of the other two of the three second coding blocks,
- wherein the largest second coding block is located between the other two of the three second coding blocks,
- wherein, with respect to the binary division for the at least one of the three second coding blocks, it is restricted so as not to be divided in a same division direction as a division direction of the triple division for the first coding block, and
- wherein the restriction is applied only to the largest second coding block among the three second coding blocks.
