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.

摘要： A decoder device receives data useable to generate data for representing a data signal at a first level of quality. The decoder device receives enhancement data useable to generate data for representing the data signal at a second, higher level of quality based on the data for representing the data signal at the first level of quality. The decoder device generates data for representing a target region of the data signal at a target level of quality using a selected portion of the received enhancement data. The selected portion is associated with the target region. The target level of quality is higher than the first level of quality. The decoder device generates data for representing a further region of the data signal at a level of quality that is lower than the target level of quality.
