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.

A method of distributing digital video products, comprising:
- generating a main stream and complementary digital information from a digital video sequence comprising coefficients, the generating comprising:
- modifying at least a non-empty subset of the coefficients within the digital video sequence to produce the main stream in a same format as the digital video sequence;
- and
- producing complementary digital information including the non-empty subset of the coefficients of the digital video sequence, information to reverse the modification of the non-empty subset of the coefficients, or both
- wherein attempting to display the main stream without using the complementary digital information results in video content that is incorrect from the standpoint of human perception;
- storing the complementary digital information;
- distributing the main stream to a user on a physical support medium;
- receiving information from a user device upon initiation of viewing the main stream stored on the physical support medium;
- and
- progressively sending portions of the complementary digital information corresponding to the main stream to the device, in response to the information received from the device upon initiation of viewing the main stream at the device, as viewing of the main stream progresses.
A system for distributing digital video sequences comprising:
- a video server, including:
- an analyzer configured to generate a main stream and complementary digital information from a digital video sequence comprising coefficients by:
- modifying at least a non-empty subset of the coefficients within the digital video sequence to produce the main stream in a same format as the digital video sequence;
- and
- producing complementary digital information including the non-empty subset of the coefficients of the digital video sequence, information to reverse the modification of the non-empty subset of the coefficients, or both;
- wherein attempting to display the main stream without using the complementary digital information results in video content that is incorrect from the standpoint of human perception;
- memory configured to store the complementary digital information;
- and
- an interface to provide the main stream for distribution to a user on a physical support medium;
- wherein the video server is configured to receive information from a user device upon initiation of viewing the main stream stored on the physical support medium and to progressively send portions of the complementary digital information corresponding to the main stream to the user device, in response to the information received from the device upon initiation of viewing the main stream at the device, as viewing of the main stream progresses.
