Digital Video Broadcasting (DVB); DVB SimulCrypt Parts 1 and 2 address the requirements for interoperability between two or more conditional access systems at a head-end. Part 1 Specifies the system architecture, timing relationships and mes saging structures. Part 2 Specifies extended interoperability and control. The components within the system architecture represent functional uni ts. The boundaries between physical equipments units are not required to match exactly the boundaries between functional units. It is possib le that the SCS could be in the MUX or the SCS and MUX could be built independently. Neither architecture is mandated.
