Abstract
An audio/video content receiver configured to receive media content by a broadcast data path, the media content includes a host module having a tuner configured to assign logical channel indices to media channels to allow selection, at the host module, of the media channels for reproduction by selecting the corresponding logical channel index, the host module storing channel association data associating the logical channel indices with the received media channels. A removable conditional access module (CAM) includes an access controller decoding access-controlled encoded broadcast content, the host module and the removable CAM to provide an encrypted communication link for decoded access-controlled encoded broadcast content between the CAM and the host module. The host module includes a detector configured to detect a conflict of logical channel index between the channel association data acquired by the host from the broadcast data path and the channel association data provided by the CAM.
