Claim 16:
17. A method according to claim 13,
the method being performed in accordance with a tiered hierarchy having multiple different levels of quality, the tiered hierarchy having at least a relatively high level of quality and a relatively low level of quality, and wherein the first set of data elements is at the relatively high level of quality,
wherein the at least one quantisation parameter comprises a first quantisation parameter and a second quantisation parameter, the first quantisation parameter being useable in performing quantisation on data at the relatively high level of quality and the second quantisation parameter being useable in performing quantisation on data at the relatively low level of quality,
wherein the first set of data elements is based on a set of residual elements, the set of residual elements being useable to reconstruct a first representation of the first time sample of the signal at the relatively high level of quality using a second representation of the first time sample of the signal at the relatively high level of quality, the second representation being based on a representation of the first time sample of the signal at the relatively low level of quality.
