<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 or of a second type that is transmitted by fewer than all of the 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.</p> |
