<p>The invention relates essentially to a device and a process for the generation of control signals which make it possible to process, on the basis of a single time reference, control signals which for writing (WE^¨B7) and reading (RE^¨B7) information relating to a video line in a storage device (7, 8). In this way, possible time lags in the synchronisation of two successive lines, occuring during transmission, are avoided. The device applies particularly to the processing of writing and reading signals in a storage device (7, 8) which is intended to store a video image line from a common time reference. Said invention is especially relevant for the construction of devices for de-scrambling coded television broadcasts, in particular those for which payment is made.</p> |
