摘要： A system controls reproduction of a video transmission between a transmitter and a receiver. The system includes an encryptor with an offset generator adapted to receive the encrypted frame key and to generate a sequence, of pseudo-random values for the color component; and an adder coupled to the offset generator and to the color component signal for providing an encoded color component signal. The system also includes a decryptor with a decryptor offset generator adapted to receive the encrypted frame key and to generate a decryptor pseudo-random value for the color component; and a subtractor coupled to the offset generator and to the color component signal for subtracting the offset signal from the color component signal.

摘要： A device (1) for displaying an aggregate image (2) the form of a matrix. Each cell (4) of the matrix (3) enables display of an elementary image (6). The elementary images are carried out on a ribbon (7). In order to vary the aggregate image, the elementary image is varied, the former being selected on the ribbon by causing the ribbon to run off inside the cell. The device enables the creation of very large display panels, particularly those used at airports.
