Abstract: In this paper, an architecture of the controlled access system for GA is discussed. It is different from the original analog conditional access system in many aspects. Three main blocks of the system are discussed here. Control center operation in transmitter end is discussed in detail because it is the core of the system. Much information like ECMs and EMMs has to be processed here, so that the multiplexer can place the information correctly in the Transport layer. It's suggested the ECMs and EMMs be transmitted safely to the subscripted user decoder by means of some syntactical fields in the Transport Stream packet, sometimes they are adaptation field and private data field. In this paper, other tools are used, that is, the descriptors in PSI tables. Two methods used in the block of scramble & descramble which performed at MPEG-2 Transport Stream level or PES level are proposed here. And the entitlement message decode is simplified.
