Digital TV Conditional Access System 3DES / AES Encryption Algorithm CAS Software

Gospell Conditional Access System

Security Enhanced Pay TV Solution for Operators

The GOSPELL Conditional Access System (CAS) is a security enhanced pay TV solution, and was designed to provide a completely secure media environment for operator content. with GOSPELL CAS, service providers can be sure that they can offer security enhanced content protection, allow them to increase Average Revenue Per User (ARPU) from subscribers, but with a low cost of ownership.It can encrypt control words and user authorization information within a stable and highly secured environment, and fully compatible with DVB Simul-Crypt standard.

In order to cater to the needs of ever-expanding digital television network, GOSPELL’s CAS enables TV operators to deploy a small or medium-size initial deployment and to be able to expand this to a large scale deployment, regardless of if this is cable, satellite or terrestrial. Furthermore, GOSPELL’s CAS supports a number of mechanisms of content protection enabling better operator investment, such as 3DES and AES encryption algorithm, smart card & STB binding, zone control, fingerprint, dual-level encryption and smart card distribution and so on.
