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.
