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;
- performing motion compensation for the first block based on motion information of the selected merge candidate;
- and
- obtaining a reconstructed value of the first block based on a result of the motion compensation;
- wherein an inter-region merge candidate included in an inter-region motion information list is added to the merge candidate list when the inter-region merge candidate is not the same as at least one merge candidate with an index value smaller than or equal to a threshold value in the merge candidate list.
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;
- performing motion compensation for the first block based on motion information of the selected merge candidate;
- and
- obtaining a residual value of the first block based on a result of the motion compensation;
- wherein an inter-region merge candidate included in an inter-region motion information list is added to the merge candidate list when the inter-region merge candidate is not the same as at least one merge candidate with an index value smaller than or equal to a threshold value in the merge candidate list.
