Abstract

A process for distributing digital video products with a restriction of at least certain rights of representation and reproduction, including an initial stage of forming a bank of original digital video sequences on a publicly inaccessible server for each request made by a user, and a stage of selection by the user of one or several sequences of the video bank, which selection stage activates a modification stage producing 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 that cannot be used on standard reading equipment, and a smaller part that is retained in the server within complementary digital information personalized for each user and complementary to the modified main stream, a stage for transmitting the main stream modified at a distribution site, a stage for recording the modified main stream at the distribution site on a standardized support material, and a stage of sending complementary digital information to the user during viewing of the modified main stream sent to the user on the material support supplied by the distributor.

Claims

1-20. -20. (canceled)

21. A process for distributing digital video products with a restriction of at least certain rights of representation and reproduction, comprising:

an initial stage of forming a bank of original digital video sequences on a publicly inaccessible server for each request made by a user, and

a stage of selection by the user of one or several sequences of the video bank, which selection stage activates

a modification stage producing 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 that cannot be used on standard reading equipment, and a smaller part that is retained in the server within complementary digital information personalized for each user and complementary to the modified main stream,

a stage for transmitting the main stream modified at a distribution site,

a stage for recording the modified main stream at the distribution site on a standardized support material, and

a stage of sending complementary digital information to the user during viewing of the modified main stream sent to the user on the material support supplied by the distributor.

22. The process according to claim 21, wherein the transmission stage of the modified main stream further comprises a stage of storing digital information that identifies the distributor.

23. The process according to claim 22, wherein the modified main stream contains digital information identifying the distributor.

24. The process according to claim 21, wherein the support is a DVD disk.

25. The process according to claim 21, further comprising a stage of reading the support with an apparatus comprising a user identifier.

26. The process according to claim 21, wherein the selection stage is realized by the user from a personal terminal of the user communicating with the video server by a public telecommunication network.

27. The process according to claim 21, wherein the stage of recording the modified main stream at the distribution site is conditioned by transmission by the user of identifying information.

28. The process according to claim 21, wherein the stage for modifying the original video sequence corresponds to a processing specific to the distributor designated by the user during the selection stage.

29. The process according to claim 28, wherein the server is connected to a database in which each specific processing is associated with an identifier of the distributor to which a resulting modified main stream is transmitted.

30. The process according to claim 21, wherein during use of the physical support obtained from the distributor, the user establishes a connection with the server, which sends the complementary digital information as viewing of the video stream progresses, which portion of complementary digital information is stored temporarily in an input memory that is a volatile memory.

31. The process according to claim 30, wherein the synthesis device receives the complementary digital information stored in a buffer and the modified main stream stored on a disk inserted in the equipment via a reading buffer, and the synthesis device uses information contained in the complementary digital information to modify the modified main stream to reconstitute a video stream identical to the original stream.

32. The process according to claim 21, wherein the stage of modifying the original video sequence corresponds to a processing specific for each user identified during the selection stage.

33. The process according to claim 32, wherein the server is connected to a database in which each specific processing is associated with a user.

34. The process according to claim 21, wherein the device records on a portable storage the complementary digital information that permits recomposition of the original stream by equipment without the equipment necessarily being connected to a transmission network, and a physical support is then connected to an interface of a module for reconstitution of the original stream.

35. The process according to claim 21, wherein the client equipment comprises a counter of a number of possible representations.

36. A system for distributing digital video sequences comprising:

a video server that carries out the process according to claim 21, at least one piece of distribution equipment comprising a video sequence recorder transmitted by the server on a physical support, and a user identifier by the video server and the distribution equipment.

37. The system according to claim 36, wherein the distribution equipment comprises an automaton/device comprising a DVD burner and conditional means of accessing the burned DVD by the user who selected a corresponding video sequence from the video server.

38. The system according to claim 36, wherein the distribution equipment and the server are locally interconnected without a link via a telecommunication network.

39. The system according to claim 36, wherein the distribution equipment comprises a printer to print an information product.

40. The system according to claim 36, wherein the distribution equipment comprises an automaton/device for distribution of recording supports.
