Abstract :
This paper presents is a downloadable conditional access system (CAS) for advanced satellite broadcasting with 4K/8K UHDTV. This CAS can perform secure access control and has security functions such as key data processing and encryption processing that can be securely updated through broadcasting or communications functions. A prototype TV receiver with the downloadable CAS was developed in order to evaluate feasibility of the proposed system.
