Title:
BITSTREAM CONFORMANCE CONSTRAINTS FOR INTRA BLOCK COPY IN VIDEO CODING
Document Type and Number:
WIPO Patent Application WO/2021/004496
Kind Code:
A1
Abstract:
A method of processing visual media includes performing a conversion between a current video block of a current picture of a visual media data and a bitstream representation of the visual media data using a buffer comprising reference samples from the current picture for derivation of a prediction block of the current video block. The conversion is based according to rule which specifies that, for the bitstream representation to conform the rule, a reference sample in the buffer is to satisfy a bitstream conformance constraint.
