Classification: CPC H | IPC H

Claim 0:
1. An encoder comprising:
memory; and
circuitry coupled to the memory and configured to:
for each of temporal sub-layers for temporal scalability different from spatial scalability, store first parameters into buffering period supplemental enhancement information (SEI) and encode the first parameters, the first parameters presenting initial delays in timing to extract data from a coded picture buffer (CPB); and
store a second parameter into the buffering period SEI and encode the second parameter, the second parameter indicating a total number of the temporal sub-layers, wherein

a value of the second parameter is equal to a value of a third parameter that is encoded into a sequence parameter set and indicates a total number of the temporal sub-layers.
