Abstract
Examples described herein relate to decoding and encoding signals. A method of performing signal decoding operations on one or more portions of a signal is presented. 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, wherein said values are associated with transformed coefficients intended to be processed by a decoder for deriving elements of the signal, and wherein said information comprises an indication of watermarking information associated with the signal.
