In an implementation, a supplemental sequence parameter set ("SPS") structure is provided that has its own network abstraction layer ("NAL") unit type and allows 5 transmission of layer-dependent parameters for non-base layers in a SVC environment. The supplemental SPS structure also may be used for view information in an MVC environment. In a general aspect, a structure is provided that includes (1) information (1410) from an SPS NAL unit, the information describing a parameter for use in decoding a first-layer encoding of a sequence of 10 images, and (2) information (1420) from a supplemental SPS NAL unit having a different structure than the SPS NAL unit, and the information from the supplemental SPS NAL unit describing a parameter for use in decoding a second-layer encoding for the sequence of images. Associated methods and apparatuses are provided on the encoder and decoder sides, as well as for the 15 signal. |
