Patent ID: 7957530

Claim:
A process for distribution of a stream having a format, the stream including multi-dimensional, animated vector visual sequences, the sequences including a succession of frames representing at least one multidimensional geometric object to be displayed on addressee equipment, the at least one multidimensional geometric object comprising at least one predefined shape that includes at least one parameter or being at least partially defined by a mathematical formula that includes at least one parameter, the process comprising: modifying the stream by substituting information in at least one of the frames, to provide at least one modified frame that is included in a modified stream, the modified stream having a format the same as the format of the stream, wherein said substituting comprises substituting at least one value for at least one parameter of at least one predefined shape or mathematical formula in at least one of the frames; generating complementary information of any format, wherein the complementary information includes digital information relative to original elements of the modified stream that were substituted, the complementary information being suitable for reconstructing the stream from the modified stream; transmitting the modified stream and the complementary information separately to the addressee equipment, to enable reconstruction of the stream on the addressee equipment as a function of the modified stream and the complementary information.
