¿µ¹® ³»¿ë¿ä¾à This standard specifies the requirements for interoperability between two or more conditional access systems at the head-end of terrestrial digital multimedia broadcasting to be constructed for pay-service. It specifies the system architecture, timing relationships, messaging structures, extended interoperability and control. This standard specifies the interfaces between Entitlement Control Message Generator (ECMG) and Multiplexer, between Entitlement Management Message Generator (EMMG) and Multiplexer, between multiplexer and synchronizer, between multiplexer and scrambler. And this standard specifies the interface of individual equipment to be use TCP/IP. The standard is only effective when the equipments are located physically separate.
