Title:
COMBINED SCREEN CONTENT CODING MODE
Document Type and Number:
WIPO Patent Application WO/2020/182113
Kind Code:
A1
Abstract:
A method of visual media processing video, includes determining that palette mode is to be used for processing a first portion of a video block and intra block copy (IBC) mode is to be used for processing a second portion of the video block, and performing further processing of the first portion of the video block using the palette mode and the second portion of the video using the IBC mode, wherein indications of the first portion of the video block processed using the palette mode and indications of the second portion of the video block processed using the IBC mode are included in a palette index identifying the first portion of the video block and the second portion of the video block.
