Claim 0:
1. A method for encoding a picture, the method comprising:
encoding a step-wise temporal sub-layer access (STSA) sample grouping that allows 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 grouped in a sample group description box (SGDP), the SGDP including 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.
