Abstract
According to aspects of the invention there is provided a method of modifying sets of residuals data where residual data can be used to correct or enhance data of a base stream, for example a frame of a video encoded using a different video coding technology. There may be provided a method of encoding an input signal, the method comprising: receiving an input signal; generating one or more sets of residuals based on a difference between the input signal and one or more reconstructed signals at one or more respective resolutions; modifying the one or more sets of residuals based on a selected residual mode; and encoding the one or more sets of modified residuals to generate one or more respective encoded streams, wherein the encoding includes transforming the one or more sets of modified residuals, and wherein the modifying includes selecting a subset of residuals not to encode based on the selected residual mode. An encoder may also be provided.
