Abstract:
The invention concerns a method for transmitting a flow of digital data and of controlled messages associated with said flow addressed to mobile terminals. The flow comprises successive bursts of data of encrypted contents with control words included in the control messages transmitted in parallel with said flow. The method is characterized in that it consists in inserting a control message in each transmitted burst of contents, said message containing at least one control word designed to decrypt the contents of said burst.
