METHOD AND DEVICE FOR SHARING A CANDIDATE LIST

摘要

The present invention relates to a method and device for sharing a candidate list. A method of generating a merging candidate list for a predictive block may include: producing, on the basis of a coding block including a predictive block on which a parallel merging process is performed, at least one of a spatial merging candidate and a temporal merging candidate of the predictive block; and generating a single merging candidate list for the coding block on the basis of the produced merging candidate. Thus, it is possible to increase processing speeds for coding and decoding by performing inter-picture prediction in parallel on a plurality of predictive blocks.

1. A method for decoding a video signal comprising:
deriving, based on a position and a size of a first prediction block, at least one merging candidate relating to the first prediction block, wherein when a size of a block indicated by parallel merge level information is equal to or greater than a first size and a size of a coding block which comprising the first prediction unit is equal to a second size, the position of the first prediction block is set equal to a position of the coding block and the size of the first prediction block is set equal to a size of the coding block; generating a merging candidate list for the first prediction block based on the at least one merging candidate; determining motion prediction information of the first prediction unit based on the merging candidate list, the motion prediction information comprising a motion vector and a reference picture index; and obtaining prediction samples of the first prediction unit based on the motion vector and a reference picture of the first prediction block, the reference picture of the first prediction block being determined by the reference picture index.
