Abstract
Examples described herein relate to decoding and encoding signals. A method of performing signal enhancement operations on one or more portions of a signal is described, wherein the performing is based at least in part on information embedded in one or more values received in one or more encoded data layers transmitted within a stream of encoded data, and wherein said values are associated with transformed coefficients intended to be processed by a decoder for deriving elements of the signal, wherein the information indicates an impairment associated with a portion of the signal.
