Abstract: A process for secure distribution of original digital audiovisual streams including audio, video components or other data, including packetizing the original stream into packets that can be manipulated and have a flexible size, wherein each packet includes a header containing information about the packet and a useful load including part of the data of the stream, analyzing the packetized stream prior to transmission to client equipment to generate a main stream in conformity with a packetized format of the original stream, modified in that all or part of the packets were substituted by packets of the same structure, but whose content was modified, and generating complementary information with any format suitable to permit reconstruction of the original stream, and separately transmitting the modified main stream and complementary information generated from the server to addressed equipment.

Abstract: A process for secure distribution of digital audiovisual 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 the original stream and complementary information of any format including digital information suitable to permit reconstruction of the original stream, wherein a transmission is made, by separate paths during distribution of the modified main stream from a distribution server and of the complementary information to the equipment of the addressee from a secure central server passing via at least one local server connecting the equipment of the addressee to the local server via at least one access point.
