Conditional Access System for Digital Satellite Broadcasting Services

摘要

A conditional access system is a system that allows broadcasters to restrict their services so that they can be accessed only by their subscribers. There is strong demand from digital satellite broadcasters for such systems in order to provide pay-TV services, so that their services can be distinguished from various other services.Toshiba has developed the Conditional Access System for Digital Satellite Broadcasting (D-CAS), based on the experience accumulated in developing conditional access systems for analog broadcasters. The system is designed to flexibly meet the different requirements of each customer, with minor modification of the application software and without changing the hardware components of D-CAS.
