Dependency Parameter Set for Scalable Video Coding

Abstract

System and methods for video decoding include receiving at least one Dependency Parameter Set (DPS); and determining at least one inter-layer dependency based on the received DPS. Systems and methods for video encoding include selecting a layering structure; encoding at least one Dependency Parameter Set (DPS) including a representation of the layering structure in a binary format; and including the encoded DPS in a bitstream or sending the encoded DPS out of band.

Description

[0001] illustrate [0002] priority claim [0003] This application claims priority to U.S. Provisional Patent Application S / N.61 / 451,454, entitled "DependencyParameterSetForScalableVideoCoding," filed March 10, 2011, the disclosure of which is incorporated by reference in its entirety included here. technical field [0004] The present application relates to video coding, and more particularly to the representation of information related to the hierarchical association of video sequences in parameter sets. Background technique [0005] Scalable video coding refers to the technique of augmenting the base layer through one or more enhancement layers. When the base layer and the enhancement layer are jointly reconstructed, the reproduced video quality can be higher than when the base layer is reconstructed alone. [0006] Multiview (multiview) coding refers to a technology in which more than one "viewpoint" is encoded in its own video sequence and the combined decoding of t...

Problems solved by technology

However, decoding SEI messages requires bit-oriented processing of the video syntax, which routers are often not prepared to do

Furthermore, interpreting SEI messages that are encoded as part of session signaling (as opposed to being encoded in the bitstream) typically requires routers to pass the signaling through, which may not be a sensible, cost-effective choice for some routers
