Signaling for addition or removal of layers in scalable video
First Claim
1. A method of signaling individual layers in a transport stream, in response to a request from a decoder, the method comprising:
- (a) determining a plurality of layers in a transport stream, wherein each layer includes a respective transport stream parameter setting, wherein said plurality of layers and respective transport stream parameter settings are pre-encoded video in said transport stream;
(b) determining an additional layer not included in said pre-encoded video in said transport stream for the plurality of layers in the transport stream, wherein the additional layer enhances one or more of the plurality of layers including a base layer and the respective layer parameter settings for the plurality of layers do not take into account the additional layer;
(c) determining an additional transport stream parameter setting for the additional layer in response to said request from said decoder indicating whether said additional layer is supported by said decoder, the additional transport stream parameter setting specifying a relationship between the additional layer and at least a portion of the plurality of layers, wherein the additional transport stream parameter setting is used to decode the additional layer;
(d) signaling in at least one descriptor carrying syntax elements in said transport stream a transport stream parameters setting for each of said plurality of layers including said additional layer;
(e) signaling in said at least one descriptor an operation point that identifies said additional layer;
(f) signaling in an extension descriptor to said at least one descriptor at least one additional transport stream setting for said additional layer, said at least one additional layer transport stream setting including a hierarchy parameter indexing a dependency between said additional layer and at least a portion of said plurality of layers.

Abstract
In one embodiment, a method of signaling individual layers in a transport stream includes: determining a plurality of layers in a transport stream, wherein each layer includes a respective transport stream parameter setting; determining an additional layer for the plurality of layers in the transport stream, wherein the additional layer enhances one or more of the plurality of layers including a base layer and the respective layer parameter settings for the plurality of layers do not take into account the additional layer; and determining an additional transport stream parameter setting for the additional layer, the additional transport stream parameter setting specifying a relationship between the additional layer and at least a portion of the plurality of layers, wherein the additional transport stream parameter setting is used to decode the additional layer and the at least a portion of the plurality of layers.
