摘要： A partial dual encryption encoder, consistent with certain embodiments of the present invention receives video from a source of an unencrypted digital video signal. A first segment of the unencrypted digital video signal is selected for transmission over a first channel. A first encrypter encrypts a second segment of the unencrypted digital video signal under a first encryption method to produce a first encrypted segment and a second encrypter that encrypts the second segment of the unencrypted digital video signal under a second encryption to produce a second encrypted segment. A multiplexer combines the unencrypted digital video signal with the first and second encrypted segments for transmission, so that the first segment is transmitted over a first channel, the first encrypted segment is transmitted over the first channel and the second encrypted segment is transmitted over a second channel. A trigger message generator generates a trigger message indicating that the second encrypted segment of the digital video signal will be encrypted and will be transmitted on a second channel. The multiplexer further combines the trigger message with the first segment, the first encrypted segment and second encrypted segment.

摘要： An encryption arrangement for multiple encryption of television programs. A system according to embodiments of the present invention multiple encrypts only a portion of the data required for full presentation of a television program to permit coexistence of multiple conditional access encryption systems associated with multiple manufacturer's set-top boxes within a single system. In one embodiment, a time slicing technique is used to encrypt portions of a program on a time allocated basis. By only encrypting a portion of the program, dramatically less bandwidth is consumed than the alternative of multiple encryption of all program data, thus permitting a larger number of programs to be carried over the same bandwidth while permitting coexistence of multiple conditional access systems in a single cable television system.
