Assembly for broadcasting scrambled digital video streams via an IP network to IP terminals connected directly to said network

摘要

The assembly has a private subscriber network part with a terminal (18) uniquely identified by a network operator using Internet Protocol (IP) address. A stage (42) of the terminal establishes a connection with an entitlement control message (ECM) decoding server (34) via an IP interface (30) of a subscriber network and a gateway (14) of the operator. A transmission unit transmits ECMs of a transport stream to the server. A receiving unit receives respective control words from the server. A cryptographic unit of the terminal secures a data exchange protocol between the terminal and the server.
