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

摘要

A method for decoding a scalable bitstream comprising a base layer and at least one enhancement layer, the method comprising obtaining information regarding a set of tiles in an enhancement layer picture; obtaining information regarding a set of tiles in a base layer picture; obtaining coding constraints for said set of tiles in the enhancement layer picture, the coding constraints comprising at least inter-layer prediction constraints in with respect to the base layer picture; and decoding said set of tiles in the enhancement layer picture according to the coding constraints as an independently decodable region.
