Claim 13:
14. An apparatus comprising:
at least one processor; and
non-transitory system memory having stored thereon computer-executable instructions which, when executed by the at least one processor, cause the apparatus to perform the following:
perform at least one transformation operation involving a plurality of correlation elements to generate at least one residual element in a first plurality of residual elements and at least one residual element in a second plurality of residual elements, the plurality of correlation elements being dependent on an extent of correlation between the first plurality of residual elements and the second plurality of residual elements, the first plurality of residual elements being useable to reconstruct a first part of a first representation of a signal at a relatively high level of quality using a first part of a second representation of the signal at the relatively high level of quality, the second plurality of residual elements being useable to reconstruct a second, different part of the first representation of the signal using a second, different part of the second representation of the signal;
derive the first part of the second representation from a first set of one or more signal elements in a representation of the signal at a relatively low level of quality;
derive the second part of the second representation from a second, different set of one or more signal elements in the representation of the signal at the relatively low level of quality; and
use at least the first plurality of residual elements, the second plurality of residual elements, the first part of the second representation and the second part of the second representation to generate output data,
wherein the at least one transformation operation is performed following the plurality of correlation elements being decoded,
wherein the at least one transformation operation implements at least one matrix multiplication, and
wherein the at least one matrix multiplication implements a first transformation operation applied to the plurality of correlation elements and a second transformation operation applied to a result of the first transformation.
