Claim of US Patent No. 10,992,943

1. An apparatus configured to:obtain a set of residual elements, the set of residual elements being useable to reconstruct a first rendition of a first time sample of a signal at a relatively high level of quality in a tiered hierarchy having multiple levels of quality using a second rendition of the first time sample of the signal at the relatively high level of quality, the second rendition being based on a rendition of the first time sample of the signal at a relatively low level of quality in the tiered hierarchy;
generate a set of spatio-temporal correlation elements associated with the first time sample of the signal, the set of spatio-temporal correlation elements being indicative of an extent of spatial correlation between a plurality of residual elements in the set of residual elements and an extent of temporal correlation between first reference data based on the first rendition and second reference data based on a rendition of a second time sample of the signal; and
use the set of spatio-temporal correlation elements to generate first output data,
wherein the rendition at the relatively low level of quality is used to generate second output data, and
wherein the apparatus is configured to generate a first set of spatial correlation elements associated with the first time sample of the signal, the first set of spatial correlation elements being indicative of the extent of spatial correlation between the plurality of residual elements in the set of residual elements.
