Abstract
A first variant of the process includes receiving an encrypted stream representing a service, this stream comprising a data channel and an ECM channel; slicing the stream to send it in packets to a mobile receiver; extracting the control message channel of this stream; forming a block containing the data channel, compatible with the diffusion to the receiver; extracting from the sliced stream a control message and introducing the control message into the block, in order to form a packet. A second variant of the process includes receiving an encrypted stream, this stream comprising a data channel and an ECM channel; cutting the stream; forming a block from the stream, comprising the data channel and the ECM channel, compatible with the diffusion to receivers; determining identical messages of the ECM channel repeated in the block and eliminating identical repeated messages, while conserving at least one of the identical messages.
