A system and method for a hybrid conditional access to encrypted transmissions

摘要

System for decrypting the encrypted transmission by a transmitting station and a receiver, the receiver comprises a second conditional access module can be removed from the first conditional access module, and the receiver embedded in the receiver. The first conditional access module is decoding the first signal transmitted by the transmitting station, and wherein the second conditional access module to decrypt the second signal transmitted by the transmitting station. It said first and second signals are encoded by a separate conditional access module. It said transmitting station provides a qualification code for causing the receiver decodes the verification during the transmission by the transmitting station is granted eligible receiver to decode the transmission to the receiver. ; The transmitting station, the conditional access module, qualification code, a removable module, the decoding algorithm, a hybrid conditional access
