Title:
METHODS OF PALETTE CODING WITH INTER-PREDICTION IN VIDEO CODING
Document Type and Number:
WIPO Patent Application WO/2016/150343
Kind Code:
A1
Abstract:
Method and apparatus for video coding using palette coding modes including a copy inter mode are disclosed. When the copy inter mode is selected, one or more consecutive current samples or indices of the current block are predicted by one or more consecutive reference samples or indices of a reference block at corresponding locations. Motion vector (MV) information for locating the reference block can be signalled in a bitstream for the current block. The motion vector information may be related to MV for the reference block corresponding to an Inter-prediction coding unit (CU) or a block vector (BV) for an Intra Block Copy (IntraBC) coded block. The location of the reference block can be determined implicitly without position information of the reference block signalled in a bitstream for the current block.
