Abstract
Aspects of the disclosure provide a method for video coding in merge mode or skip mode. The method can include receiving a prediction block (PB) of a picture, determining number and positions of merge candidates of the PB according to a size and/or a shape of the PB, and constructing a candidate list including motion data of a subset of the merge candidate positions.
Claims12
A method for video coding, comprising:
- receiving a current block of a picture;
- determining a number of merge candidate positions of the current block according to a size of the current block, wherein the merge candidate positions are positions of spatial or temporal merge candidates, and the step of determining the number of the merge candidate positions comprises:
- when the size of the current block is not larger than a predetermined size, the number of the merge candidate position is determined to be zero;
- identifying the merge candidate positions on sides of the current block in accordance with the number of the merge candidate positions;
- and
- constructing a candidate list for the current block based on motion data associated with the identified merge candidate positions.
