    摘要: A process for the distribution of digital audiovisual sequences. An analysis is made prior to transmission to a dynamic group of receivers to generate a first modified main stream and complementary information. A synthesis of a stream in the original format is calculated on the receiver as a function of the modified main stream and the complementary information. Generation of the complementary information is constituted of the following steps: extraction of at least one original piece of data of the original stream, storage of the original data in the complementary information, formatting the complementary information in segments with each segment corresponding to at least one entire audiovisual element of the modified main stream, and encapsulation of at least one segment with at least one piece of access information in at least one data block to generate at least one access ticket for the corresponding audiovisual elements.
