DEPENDENCY PARAMETER SET FOR SCALABLE VIDEO CODING
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.
1 . A method for video decoding, comprising:
receiving at least one Dependency Parameter Set (DPS); and
determining at least one inter-layer dependency based on the received DPS.
2 . The method of claim 1 , wherein the DPS further includes a representation of a layering structure in binary form.
3 . The method of claim 1 , wherein the DPS further includes a flag indicating a presence of a layering structure in binary form.
4 . The method of claim 1 , wherein the DPS further includes a flag indicating the presence of a multiview structure.
5 . The method of claim 1 , wherein the DPS further includes a flag indicating the presence of Visual Usability Information pertaining to a plurality of layers.
6 . The method of claim 1 , wherein the DPS further includes a flag indicating the presence of an extension of the DPS.
7 . The method of claim 1 wherein the DPS further includes a value indicating a number of layer descriptions.
8 . The method of claim 2 , wherein the representation of the layering structure comprises two or more of layer descriptions corresponding to two or more layers.
9 . The method of claim 8 , wherein at least one of the two or more layer descriptions includes a flag indicating that the layer depends, through inter-layer prediction, on another layer.
10 . The method of claim 8 , wherein a layer description pertaining to a first layer of the two or more layers includes an identification of a second layer of the two or more layers, and wherein the first layer depends on the second layer through inter-layer prediction.
11 . The method of claim 8 , wherein the two or more layer descriptions comprise spatial layer descriptions.
12 . The method of claim 11 , wherein the layer description pertaining to a first layer of the two or more layers includes information about at least a second layer of the two or more layers which depends on the first layer.
13 . The method of claim 12 , wherein the first layer is a spatial layer, and the information is a number of quality layers of the two or more layers depending on the spatial layer.
14 . The method of claim 9 , wherein in at least two of the two or more layer descriptions, the flag indicating that the layer depends, through inter-layer prediction, on another layer, indicates no inter-layer prediction.
15 . A method for video encoding, comprising:
selecting a layering structure;
encoding at least one Dependency Parameter Set (DPS) including a representation of the layering structure in a binary fauna; and
performing one of: including the encoded DPS in a bitstream, or sending the encoded DPS out of band
