Abstract
A video decoding method includes the steps of: generating a merge candidate list for a first block; selecting one among merge candidates included in the merge candidate list; and performing motion compensation for the first block based on motion information of the selected merge candidate. At this point, an inter-region merge candidate included in an inter-region motion information list may be added to the merge candidate list based on the number of spatial merge candidates and temporal merge candidates included in the merge candidate list.
Claims19
A video decoding method, comprising:
- generating a merge candidate list for a first block;
- selecting one among merge candidates included in the merge candidate list;
- and
- performing motion compensation for the first block based on motion information of the selected merge candidate;
- wherein
- the merge candidates comprise a first merge candidate and a second merge candidate, and a prediction block for the first block is generated based on the first merge candidate and the second merge candidate;
- index information merge_idx of the first merge candidate and index information merge_2nd_idx of the second merge candidate are obtained by analyzing a bitstream;
- and when a value of index information merge_2nd_idx is equal to or greater than a value of index information merge_idx, a value of an index of the second merge candidate is obtained by adding 1 to the value of index information merge_2nd_idx.
A video encoding method, comprising:
- generating a merge candidate list for a first block;
- selecting one among merge candidates included in the merge candidate list;
- and
- performing motion compensation for the first block based on motion information of the selected merge candidate;
- wherein
- the merge candidates comprise a first merge candidate and a second merge candidate, and a prediction block for the first block is generated based on the first merge candidate and the second merge candidate;
- index information merge_idx of the first merge candidate and index information merge_2nd_idx of the second merge candidate are signaled through a bitstream, respectively, and when a value of index information merge_2nd_idx is equal to or greater than a value of index information merge_idx, a value of an index of the second merge candidate is obtained by adding 1 to the value of index information merge_2nd_idx.
