Title:
METHOD AND APPARATUS FOR VIDEO CODING
Document Type and Number:
WIPO Patent Application WO/2019/209444
Kind Code:
A3
Abstract:
Aspects of the disclosure provide methods and apparatuses for video decoding. In some examples, an apparatus includes processing circuitry. The processing circuitry decodes prediction information of a current block from a coded video bitstream. The prediction information is indicative of an intra block copy mode. Then, the processing circuitry determines, according to the intra block copy mode, a first portion of a resolution syntax. The resolution syntax is unified of a same semantic for block vectors in the intra block copy mode and motion vectors in an inter picture merge mode. Further, the processing circuitry decodes a second portion of the resolution syntax from the coded video bitstream, and determines a block vector according to a resolution that is indicated by a combination of the first portion and the second portion. Then, the processing circuitry reconstructs at least one sample of the current block according the block vector.
