The shifting system comprises a local scrambler (13) on a production site giving the necessary digital data elements to a scrambler (15) shifted to a transmission site. These data elements are inserted, at the image rate, into the compressed television signal transmitted on a low bit rate link to the transmission site. The application relates to systems for the transmission of encrypted television systems.
