METHOD AND APPARATUS FOR NON-BINARY PROFILE CONSTRAINT SIGNALING FOR VIDEO CODING

摘要

A method, apparatus and computer program product provide non-binary profile constraints in image or video bitstreams such that a decoder is able to determine whether the decoder can decode the bitstream without completely decoding the bitstream. The method, apparatus and computer program product encode one or more source pictures into a bitstream. The encoding characterized by one or more coding properties (20). The method, apparatus and computer program product further encode a syntax structure indicating the one or more coding properties of the bitstream into or along the bitstream (22). The syntax structure includes a first portion including one or more fixed syntax elements with one or more pre-defined lengths in bits at one or more pre-defined bit positions and a second portion comprising one or more conditional syntax elements. Presence of the conditional syntax element(s) is conditioned based on one or more values associated with the one or more fixed elements.
