Abstract
A system (100) and method (200) for delivering conditional access information to a conditional access controlled device (120) incompatible with the conditional access transmission protocol. The conditional access information is delivered through a conditional access controlled device (110) compatible with the conditional access transmission protocol via a home network connection (130) between the conditional access controlled devices and according to a home network transmission protocol with which both conditional access controlled devices are compatible. The device (110) compatible with the conditional access transmission protocol receives the conditional access information on behalf of the device (120) incompatible with the conditional access transmission protocol, reformats the received conditional access information according to the home network transmission protocol, and transmits the reformatted information to the device (120) incompatible with the conditional access transmission protocol according to the home network transmission protocol and via the home network connection (130).
