AN APPARATUS, A METHOD AND A COMPUTER PROGRAM FOR VIDEO CODING AND DECODING

摘要

A method for decoding an encoded video representation from a bitstream, the method comprising decoding an identifier indicating that all samples within a scope of the bitstream have been coded with a prediction restriction; determining that the scope covers a region of interest within a picture; decoding at least a first coding unit preceding said region of interest in decoding order in a parse mode such that syntax elements belonging to said at least first coding unit are parsed, but a sample reconstruction process of said syntax elements is omitted; and decoding at least a second coding unit belonging to said region of interest such that syntax elements belonging to said at least second coding unit are parsed and a sample reconstruction process is performed to said syntax elements.
