摘要： According to an aspect of the invention there may be provided a method of encoding a stream of data, the method comprising: receiving an input signal; applying a first encoding operation on the input signal using a first codec to generate a first encoded stream; and, applying a second encoding operation on the input signal to generate a second encoded stream, wherein the first and second encoded streams are for combination at a decoder; and wherein the method further comprises exchanging information between the first encoding operation and the second encoding operation. A method of decoding, an encoder, decoder and computer readable medium are also provided.

摘要： First and second pluralities of residual elements useable to reconstruct first and second respective parts of a representation of a signal are obtained. A transformation operation is performed to generate at least one correlation element. The transformation operation involves at least one residual element in the first plurality and at least one residual element in the second plurality. The at least one correlation element is dependent on an extent of correlation between the at least one residual element in the first plurality and the at least one residual element in the second plurality. The transformation operation is performed prior to the at least one correlation element being encoded.

摘要： A set of reconstruction elements useable to reconstruct a representation of a signal at a relatively high level of quality using data based on a representation of the signal at a relatively low level of quality is obtained. The representation at the relatively high level of quality is arranged as an array comprising at least first and second rows of signal elements. A reconstruction element is associated with a respective signal element in the set. A set of data elements is derived based on the set of reconstruction elements. At least one of the data elements is derived from at least two reconstruction elements associated with signal elements from the first row and a different number of reconstruction elements associated with signal elements from the second row.
