Abstract
A system for decrypting multiple transport streams is disclosed. The system includes: a Multiple Transport stream Multiplexer (M-Mux), for receiving at least a first transport stream and a second transport stream, and outputting a resultant transport stream; a multiple transport stream decryption card for decrypting the resultant transport stream to output a decrypted transport stream; a Source Multiplexer (S-Mux) for receiving the decrypted transport stream from the multiple transport stream decryption card and the resultant transport stream, and outputting a final resultant transport stream; and a Multiple Transport Stream Processor (M-Processor) for receiving the final resultant transport stream, and sending the final resultant transport stream to a corresponding framer.
