Embodiment Construction

[0041]The disclosed subject matter provides a Dependency Parameter Set (DPS) that captures information associated with a scalable bitstream including a binary representation of the layer structure; Visual Usability Information (VUI) associated with all scalable bitstream layers; and allows Extensibility An extension mechanism for use by future video encoding mechanisms. DPS may share features of other parameter sets; for example it may be sent in-band or out-of-band, and may be directly retrieved from other parameter sets, slice headers, or other appropriate syntax elements such as access unit qualifiers or access unit / graphic headers. or indirectly quoted.

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.
