METHOD FOR PREDICTING DISPARITY VECTOR BASED ON BLOCKS FOR APPARATUS AND METHOD FOR INTER-LAYER ENCODING AND DECODING VIDEO

摘要

Provided is an inter-layer video decoding method including: searching for a neighboring block candidate having a motion vector in an inter-layer direction from among a spatial neighboring block candidate located at the left of a current block, a spatial neighboring block candidate located at the top of the current block, and temporal neighboring block candidates at co-located locations; predicting a motion vector in an inter-layer direction of a found neighboring block candidate as a disparity vector of the current block; when the neighboring block candidate having the motion vector in the inter-layer direction is not found, searching for a neighboring block candidate having disparity vector information from among the spatial neighboring block candidates; and predicting a disparity vector of the current block by using disparity vector information of a found neighboring block candidate.
