Summary

Recommendation ITU-T J.1028 specifies a terminal for a one-way downloadable conditional access system (DCAS) for unidirectional networks. 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 (STB), to adapt to a new CA system by downloading and installing the new client of the CA system without changing hardware. In particular, one-way DCAS can fully work in unidirectional cable TV networks and other unidirectional networks such as satellite TV networks.
