METHOD AND APPARATUS FOR VIDEO ENCODING WITH INTER PREDICTION USING COLLOCATED PICTURE, METHOD AND APPARATUS FOR VIDEO DECODING WITH INTER PREDICTION USING COLLOCATED PICTURE

摘要

Provided is an inter-prediction method including the steps of: determining a collocated block for a current block of a current image among blocks of an image restored prior to the current image; checking whether a first reference list is preferentially referred to in reference lists of the collocated block; checking whether a second reference list is selectively referred to according to whether the first reference list is referred to; determining a single collocated reference list; and performing inter-prediction for the current block using the reference block of the current block determined according to motion information of the collocated reference list.
