Abstract: A process for distributing digital video products with a restriction of at least certain rights of representation and reproduction may include selection by a user of one or several video sequences, modification of the video to produce a modified main stream in a nominal format of a selected original video sequence, but whose content was modified by cutting into two parts, a larger part of which is recorded in the modified main stream and a smaller part that is retained in the server within complementary digital information, transmitting the modified main stream to the user, and sending complementary digital information to the user during viewing of the modified main stream.

Abstract: A method for distributing a digital image content, including a modification stage of an original digital image content by modifying at least a part of digital image data, the modification producing a modified digital image content of the same nominal format as the original digital image content, transmitting the modified digital image content, and a reconstruction stage implemented within a decoder for obtaining a reconstituted digital image content, wherein the reconstruction is adaptive and progressive as a function of information coming from a digital profile of the recipient.

Abstract: A process for distributing digital audio sequences according to a nominal stream format that include a succession of frames, each of which includes at least one digital audio block grouping a plurality of coefficients corresponding to digitally coded audio elements, including modifying at least one block of an original stream of sequences, in an adaptive manner on the original stream as a function of at least a part of characteristics representative of the structure, content and parameters of the original stream, a target profile and external events.

Abstract: Methods and systems are disclosed for distributing video sequences in a coded stream. The methods and systems include analyzing an original coded stream, generating at least one modified coded sub-frame, generating, based upon the analysis, a modified stream and a second stream by replacing an original coded sub-frame by the modified coded sub-frame, so that the modification from the original coded sub-frame results in a visually altered video sequence, transmitting the first and the second generated streams, and reconstructing the original stream using the modified coded sub-frame contained in the second stream.

Abstract: A process for secure distribution of video sequences coded in accordance with a nominal stream format including visual data and data for configuration of decoding of the stream that does not represent the visual data, wherein, prior to transmission to client equipment, an analysis is made of the stream for generating a modified main stream having a format of the nominal stream and having pictures/images modified by modification of the data for configuration of decoding, and complementary digital information of any format including digital information suitable to permit reconstruction of modified pictures, then, for separately transmitting the modified main stream and complementary digital information generated from a server to the client equipment, and wherein a synthesis of a stream in the nominal format is calculated on the client equipment as a function of the modified main stream and the complementary information.

Abstract: Embodiments of the invention may relate to the distribution of digital audiovisual sequences. The distribution of such sequences may involve generating and transmitting modified sequences and complementary information. The complementary information may allow reconstruction of the original sequences from the modified sequences.

Abstract: A method of distributing digital video sequences in the form of a stream including sequences of data containing digital images, including a modification stage of an original stream by modifying at least a part of the sequences, the modification producing a modified stream of the same nominal format as the original stream, transmitting the modified stream, and a reconstruction stage implemented with a decoder, wherein the reconstruction is adaptive and progressive in function of information coming from a digital profile of the recipient.

Abstract: A process for secured distribution of video sequences according to a digital stream format stemming from an encoding based on a processing by wavelets including frames including blocks containing coefficients of wavelets describing the visual elements, including analyzing the stream prior to transmission to client equipment to generate a modified main stream by deletion and replacement of selected information coding the original stream and having the format of the original stream, and complementary information of any format comprising the digital information coding the original stream and suitable for permitting reconstruction of the modified frames; and transmitting the modified main stream and the complementary information separately from a server to addressed equipment.

Abstract: A method of distributing video sequences according to a nominal flow format including a succession of frames each including at least one I block corresponding to a complete digital I image and at least one N block corresponding to differences between a digital N image and at least one other image including analyzing the flow of sequences to generate a first modified flow having a format of a nominal flow and having modified N blocks and a second flow of any format including digital information required to reconstruct the modified blocks; and transmitting the first and second flows from a server to destination equipment, and calculating on the destination equipment a synthesis of a flow in a nominal format as a function of the first flow and the second flow.

Abstract: A process for distributing audiovisual sequences may involve generating a modified main stream from an audiovisual sequence as well as complementary information that may enable equipment receiving the modified main stream and the complementary information to synthesize the audiovisual sequence. The modified main stream and the complementary information may be separately transmitted to the equipment.
