摘要：
For a given image in a set of images, residual data is obtained and is useable by a decoder to reconstruct a first representation of the given image at a first level of quality using a second representation of the given image at the first level of quality. The second representation is based on a representation of the given image at a second, lower level of quality. Configuration data relating to processing of the residual data is generated and output for processing by the decoder. The configuration data comprises a temporal processing parameter that specifies an extent of temporal processing associated with reconstructing, for the given image, the first representation using the second representation and the residual data, wherein performing temporal processing comprises using data based on multiple images in the set of images.
