    摘要: The present invention concerns a transmitter and a receiver and a method thereof for permitting a receiver to reconstruct a stream at a constant bit rate. In particular it concerns a method for transmitting first packets encapsulated in second packets in a transmission system, comprising the steps, at the transmitter, of collecting a predetermined number of the first packets, and triggering transmission of the second packet encapsulating the collected first packets, the second packet comprising a timestamp for each one of the first packets.

    摘要: 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.
