Abstract :
This paper presents an efficient design and implementation of user terminal for Downloadable Conditional Access System (DCAS). The DCAS system enables cable operators to flexibly change and update their Conditional Access Systems (CAS) without hardware changes by downloading CA applications through Hybrid Fiber Coaxial (HFC) network. In order to do this, the DCAS user terminal provides DCAS functionalities including CA client download and update through DCAS protocol. The proposed design and implementation in this paper can be used to develop advanced DCAS user devices such as smart phone supporting broadcasting and communication converged services.
