Abstract
An audio/video content delivery system having a network content source linked by an internet data connection to a content receiver that receives content from the network content source via the internet data connection, and also receives access-controlled encoded broadcast content from the network content source or another content source via a separate broadcast data path. The network content source requests a client certificate from the content receiver. The content receiver includes a host module to store a network client certificate and send it to the network content source, and a conditional access module (CAM) with an access control unit for decoding the access-controlled encoded broadcast content. The host module and the CAM provide an encrypted communication link for decoded access-controlled encoded broadcast content. The broadcast content source transmits a client certificate to the CAM. The CAM transmits the client certificate to the host module via the encrypted communication link.
