- Abstract
- Recommendation ITU-T J.1027 specifies a system architecture for a one-way downloadable conditional access system (DCAS) for unidirectional networks. A one-way DCAS protects broadcast content or services and controls consumer entitlements like traditional conditional access (CA) systems, and enables a terminal, such as a set top box , to adapt to a new CA system by downloading and installing the new client of a CA system without changing the hardware. In particular, a one-way DCAS can fully work in unidirectional cable television (TV) networks and other unidirectional networks such as satellite TV networks.
