Abstract
Signal data is processed at an encoder device. A representation of a signal at a first level of quality is obtained. The representation at the first level is upsampled using an upsampler in the encoder device to derive a preliminary representation of the signal at a second, higher level of quality. Adjustment data is derived using the representation at the first level as an input to an upsampling adjuster arranged in parallel with the upsampler in the encoder device. The adjustment data is useable by the encoder device to adjust the preliminary representation. The preliminary representation and the adjustment data are used to derive an adjusted representation of the signal at the second level. Residual data useable by a decoder device is derived, using the adjusted representation, to reconstruct a reference representation of the signal at the second level using the adjusted representation.
