<p>A method and apparatus for receiving conditional access information (CAI) on one or more of a plurality of tuners receiving the CAI from a first tuner of the plurality of tuners is disclosed. The method comprises the steps of determining if the CAI is of a first type that is transmitted by all of a plurality of transponders; passing, to a conditional access module, only CAI from the first tuner and rejecting CAI from any other tuner if the CAI is of a type that is transmitted by all transponders; and passing, to the conditional access module, all CAI from any of the plurality of tuners if the CAI is of a type that is transmitted by fewer than all transponders. A method of processing CAI is also disclosed which comprises the steps of identifying the channel transmitting the CAI from the channel information, determining if any of the plurality of tuners are tuned to the identified channel, and passing the CAI to the conditional access module only if at least one of the plurality of tuners is tuned to the identified channel.</p> |
