Abstract

This paper proposes a conditional access system (CAS) that is appropriated in T-DMB and based on an effective multiplexing method for providing a variety of encrypted T-DMB services. The developed CAS in T-DMB is designed to encrypt selected services of all T-DMB services according to the CA modes. Transmitting T-DMB transport stream encrypted by the proposed ensemble multiplexer, we verified their performance by de-scrambling and decoding according to CA mode at the receiver platform.
