摘要： 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.

摘要： The secure audio visual data distribution process has separate transmission channel transmission in the distribution phase. The digital stream is modified by the distribution server and complementary information added. An intermediate server connects to the central server. The complementary information has a nominal structure format with processing units and with the format placed in headers.

摘要： The method involves analyzing an input video flow (2) to generate a main modified flow (5) having an input video flow format, and complementary information (4) permitting a reconstruction of the input video, before transmitting the input video flow to a client equipment. The main modified flow and complementary information are transmitted separately from a server (6) towards the equipment, during a distribution phase. An independent claim is also included for a video flow creating system for implementing a method of secured distribution of video sequences according to a digital flow format based on a discrete cosine transform (DCT).

摘要： The automatic and adaptive visual digital stream scrambling process analyses the stream structure and contents. Scrambling is carried out dependent of decisional motor inferences from a library of scrambling tools and applied to the stream as a function of the analysis using a pre defined rule base scrambling process.

摘要： The MPEG-4 type multimedia and equipment includes a processor which is able to display all MPEG-4 type video stream in real or delayed time. A memory unit holds certain movement vectors in planes, and for the planes themselves on the video stream in each audio-visual portal (12). This enables storage in scrambled format, preventing unauthorised copying. The MPEG-4 type multimedia and video interfacing equipment is used to connect a display to a video source. It includes a processor which is able to display all MPEG-4 type video stream in real or delayed time, to store the video stream, to record the video stream, to send the video stream over a broadcast network (4) or a low bandwidth wide area telecommunications network (10) and to record the video stream on a chip card. The system further comprises a screen interface (7) and a local or wide area network interface (5,9), and a chip card reader. A memory unit holds certain movement vectors in planes, and for the planes themselves on the video stream in each audio-visual portal (12). Interfacing equipment (8) restores the MPEG-4 streams with algorithms originating from information from the hard disc.

摘要： The process involves selecting an original digital video sequence from bank of original digital video sequences by a user, to activate transmission of the video sequence in a nominal format with modified video contents. An information that is personalized for the user and complementary to the selected sequence is registered and provided during viewing of the modified video sequence, in a support medium e.g. DVD. An independent claim is also included for a digital video sequence distribution system.
