Patent ID: 8619871

Claim:
A method comprising: accessing information from a sequence parameter set (â€œSPSâ€) network abstraction layer (â€œNALâ€) unit, the information describing a parameter for use in decoding a first-layer encoding of an image in a sequence of images; accessing supplemental information from a supplemental SPS NAL unit having an available NAL unit type code that is a different NAL unit type code from that of the SPS NAL unit, and having a different syntax structure than the SPS NAL unit, and the supplemental information from the supplemental SPS NAL unit describing a parameter for use in decoding a second-layer encoding of the image in the sequence of images; and decoding the first-layer encoding, and the second-layer encoding, based on, respectively, the accessed information from the SPS NAL unit, and the accessed supplemental information from the supplemental SPS NAL unit.
