Abstract
A method and apparatus for providing an integrated presentation of existing media program services and secondary media program services is described. The method comprises the steps of receiving and displaying an electronic program guide comprising channels and programs carried by both the primary service and the secondary service, accepting a election of a secondary media program or channel displayed on the electronic program guide but transmitted on a secondary media program channel; accessing a mapping to determine a primary media program channel associated with the selected secondary media program channel; commanding a first tuner module to receive conditional access information associated with the primary media program channel from the primary service provider; evaluating the conditional access information to determine if a second tuner is authorized to receive the secondary media program channel and or evaluating the subscriber access information carried on the electronic program guide; and commanding a second tuner module to receive the secondary media program if the second tuner is authorized to receive the secondary media program channel.
