FIELD: radio engineering, communication.SUBSTANCE: disclosed is a method and a system for decoding a data stream which includes a series of data frames, where the method includes a step of generating a cryptographic value for a block of N consecutive data frames and configuration information, characterised by that the configuration information includes information for rendering the data stream; the method then inserts the cryptographic value into the data stream, following the N consecutive data frames.EFFECT: enabling to make a distinction between a data stream, or a bit stream, or a bit stream generated by a corresponding Dolby Pulse encoder and a data stream, or a bit stream, generated by any arbitrary encoder compatible with HE-AACv2.38 cl, 8 dwg |
