Abstract:
A process for secure distribution of digital audio streams according to a standard, normalized or proprietary format, on which streams a separation of the stream into two parts is made prior to transmission to equipment of an addressee to generate a modified main stream having a format of an original stream and complementary information including digital information suitable for permitting reconstruction of the original stream including: transmitting, by separate paths during a distribution phase, the modified main stream from a distribution server and the complementary information to the equipment of the addressee from a secure central server passing via at least one intermediate server connecting the equipment of the addressee to the central server, wherein the complementary information is defined according to a nominal structured format containing processing units which comprise logical entities with a modulatable size and wherein each of the processing units is prefixed by a heading containing information relative to the processing unit and a useful load containing data and references about the modified main stream, and packetizing the units prior to the transmission.
