Abstract

A device and method for multiple access cards to interface to at least one integrated receiver/decoder (IRD) and methods for using the device. The interface device of the present invention contains multiple access card readers and houses multiple access cards. The device can switch between access cards based on pre-configured software that rotates the cards according to various conditions. In another embodiment, the device can simultaneously operate all the cards. The device can select one card for the IRD based on responses acquired for the various conditions. In addition, the present invention allows monitoring access card authorizations and blackout states in multiple IRDs. A single access card can be applied to more than one IRD simultaneously, and the IRDs can be different versions. In addition, the present invention provides a satellite broadcast center with the capability of testing multiple access cards in real time either sequentially, or in parallel, through multiple IRDs.

Claims

1. A system for interfacing at least one access card with at least one integrated receiver decoder, said system comprising:

a housing;

at least one card reader in the housing;

an electrical interface in the housing, the electrical interface being between the at least one card reader and the at least one integrated receiver decoder;

a plurality of slots for holding a plurality of access cards, each of the plurality of slots in selective electrical communication with said at least one card reader through an electrical interface;

a processor for controlling a selection of only one of the plurality of access cards to provide information to the at least one integrated receiver decoder to allow access to programming, wherein said processor further comprises predetermined access conditions programmed therein that determine the selection of an access card, whereby upon the predetermined access conditions being met by the one of the plurality of access cards, the removal of an existing access card from the integrated receiver decoder and the insertion of another access card into the integrated receiver decoder is automatically simulated.

2. The system as claimed in claim 1 wherein the electrical interface is a tongue member that is inserted in the at least one integrated receiver decoder, the tongue member being movable between the housing and the at least one integrated receiver decoder.

3. The system as claimed in claim 1 wherein said plurality of slots comprises a rack member for holding the at least one access card.

4. The system as claimed in claim 1 wherein said plurality of slots comprises a carousel member for holding the at least one access card.

5. The system as claimed in claim 1 wherein said predetermined access conditions are set by a broadcast provider.

6. The system as claimed in claim 1 further comprising a display interfaced to the processor.

7. The system as claimed in claim 6 wherein the display further comprises an operator interface for inputting parameters to the processor, whereby the parameters affect the predetermined access conditions.

8. The system as claimed in claim 1 further comprising a personal computer interfaced with the processor.

9. A method for interfacing more than one access card to a plurality of integrated receiver/decoders, each having a card reader comprising the steps of:

simultaneously interfacing with a plurality of access cards with an interface device to sense predetermined conditions that determine the selection of an access card from a plurality of access cards;

directing the interface device to simulate the insertion of the selected access card to the at least one integrated receiver/decoder;

electrically interfacing the selected access card to a card reader in the at least one integrated receiver/decoder; and

sliding a tongue of the interface device in and out of the card reader of each integrated receiver/decoder as a plurality of integrated receiver/decoders are cycled by to sense predetermined conditions that determine the selection of an access card, thereby interfacing more than one access card to more than one integrated receiver/decoders.
