Patent ID: 11871014
Assignee: DOLBY INTERNATIONAL AB
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A non-transitory computer-readable medium having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
receiving an audio-visual bitstream;
obtaining a step-wise temporal sublayer access (STSA) sample grouping;
decoding the STSA sample grouping; and
determining when to switch to a new temporal layer based on the STSA sample grouping,
wherein the STSA sample grouping is a group of STSA samples sent in a sample group description box (SGDP), and wherein the SGDP includes a next STSA upswitching distance parameter and a next STSA sample distance parameter, wherein the next STSA upswitching distance parameter is different from the next STSA sample distance parameter, and wherein the next STSA sample distance parameter indicates a distance of a next temporal layer switching point in a current temporal layer, and wherein the next STSA upswitching distance parameter indicates a distance of a next temporal layer up switching point in a temporal layer higher than the current temporal layer.
