Abstract
A device and to a method for generating control signals is set forth. The device according to the present invention allows the generation, from a single time reference, of the write control (WE) and read control (RE) signals for the information relating to a video line in a storage device (7, 8, 17, 18, 20). In this way, possible shifts between the synchronization of two successive lines due in particular to the transmission are overcome. The device according to the present invention is applied in particular to the generation, from a common time reference, of write signals and of read signals for a storage device (7, 8, 17, 18, 20) intended for storing a video image line. The invention applies principally to the production of devices for unscrambling scrambled television transmissions, particularly pay television transmissions.
