摘要： Essential data elements, particularly entitlement control messages (ECMs), are inserted in a manner that reduces the overhead bit rate without effecting overall tuning time at the customer receiver or security in satellite, cable or other programming networks. ECMs are inserted into the transport stream by detecting random access points (RAPS) in the encoded programming and inserting the ECM packets in a window just ahead of the RAP.

摘要： A method and apparatus for storing and retrieving program material for subsequent replay is disclosed. In summary, the present invention describes a system and method for storing and retrieving program material for subsequent replay. The method comprises the steps of accepting encrypted access control information and the program material encrypted according to a first encryption key, the access control information including a first encryption key and control data; decrypting the received access control information to produce the first encryption key; decrypting the program material using the first encryption key; re-encrypting the program material using according to a second encryption key; encrypting the second encryption key according to a third encryption key to produce a fourth encryption key; and providing the re-encrypted program material and a fourth encryption key for storage. The apparatus comprises a conditional access module, for accepting encrypted access control information and the program material encrypted according to a first encryption key, the encrypted access control information including the first encryption key and temporally-variant control data, the control access module comprising a first decryption module, for decrypting the access control information to produce the first encryption key; a first encryption module, for encrypting a second encryption key with a third encryption key to produce a fourth encryption key; and a second decryption module for decrypting the fourth encryption key to produce the second encryption key.

摘要： A communication system 10 includes a head end 12. The head end communicates with a system gateway 26. A plurality of user devices 28 is coupled to the gateway 26. The gateway receives the plurality of first encrypted signals, decrypts the plurality of first encrypted signals to form unencrypted signals and encrypts the unencrypted signals with a second encryption to form a plurality of second encrypted signals and communicates the second encrypted signals to the plurality of user devices. The signals may also be super-encrypted signals. That is, rather than un-encrypting at the gateway, the first encrypted signals may be again encrypted.
摘要翻译：通信系统10包括头端12.头端与系统网关26通信。多个用户设备28耦合到网关26.网关接收多个第一加密信号，对多个第一加密信号进行解密以形成未加密的信号并用第二加密来加密未加密的信号，以形成多个第二加密信号，并将第二加密信号传送到多个用户设备。信号也可以是超加密信号。也就是说，不是在网关处解密，而是可以再次加密第一加密信号。
