Claims
- 1. An apparatus comprising an adapter, said adapter comprising:a slot that receives a smart card; a connector; a passive router that routes signals from the smart card to the connector; a first converter to convert a scrambled data stream in a parallel format into a serial signal for output via the connector to the adapter; and a second converter to receive a descrambled serial data stream from the adapter through the connector and to convert the descrambled serial data stream into a descrambled parallel data stream.
- 2. The apparatus of claim 1 further comprising a host conditional access module coupled to the adapter through the connector.
- 3. The apparatus of claim 2 wherein the host conditional access module further comprises an outgoing converter to convert an outgoing signal from a first format to a second format.
- 4. The apparatus of claim 3, wherein the first format of the signal is parallel, and the second format of the signal is serial.
- 5. The apparatus of claim 2 wherein the host conditional access module further comprises an incoming converter to convert an incoming signal from a second format to a first format.
- 6. The apparatus of claim 5 wherein the second format is serial and the first format is parallel.
- 7. An adapter comprising:a slot to receive a smart card; a connector to connect to a conditional access module; a first converter to convert a scrambled data stream in a parallel format from the conditional access module into a serial signal for output to the smart card; and a second converter to receive a descrambled serial data stream from the smart card and to convert the descrambled serial data stream into a descrambled parallel data stream for output to the conditional access module.
- 8. A connector comprising:a PCMCIA connector to form a connection between a PCMCIA card and a conditional access module being further adapted with a first converter to convert a scrambled data stream in a parallel format into a serial signal for output over a first selected pin of the PCMCIA connector and a second converter to receive a descrambled serial data stream from a smart card and to convert the descrambled serial data stream into a descrambled parallel data stream for output to the conditional access module; and a smart card reader to form a connection between the smart card and the conditional access module.
- 9. The converter of claim 8 further comprising a smart card slot to hold the smart card.
- 10. The converter of claim 9, further comprising a plastic insert that can be inserted into the smart card slot so that the connection between the smart card and the smart card reader is maintained.
- 11. An apparatus comprising:a first slot; a PCMCIA connector positioned substantially at a rear of the first slot; an adapter configured for insertion into the first slot, the adapter comprises a second slot configured to receive a smart card, a connector positioned at the adapter for coupling to the PCMCIA connector, and a passive router that routes signals from the smart card to the connector; a first converter to convert a scrambled data stream in a parallel format into a serial signal for output over a first selected pin of the PCMCIA connector to the adapter; and a second converter to receive a descrambled serial data stream from the adapter over a second selected pin of the PCMCIA connector and to convert the descrambled serial data stream into a descrambled parallel data stream.
- 12. The apparatus of claim 11, wherein the passive router of the adapter establishes an electrical connection with ISO contacts of the smart card and routes information from the smart card to the connector.
- 13. The apparatus of claim 11, wherein the adapter is separate and removable from the first slot.
- 14. The apparatus of claim 11, wherein the first slot is a PCMCIA Type 2 slot.
- 15. The apparatus of claim 11 further comprising:a first switch coupled to the first converter to receive the scrambled data stream and to provide the scrambled data stream to the first converter when the adapter is inserted into the first slot and coupled to the PCMCIA connector.
- 16. The apparatus of claim 15 further comprising a second switch coupled to the first switch and the first converter, the first switch to provide the scrambled data stream, excluding data destined for the first selected pin of the PCMCIA connector, directly to the PCMCIA connector if a PCMCIA card is inserted into the slot and is coupled to the PCMCIA connector in lieu of the adapter and the smart card, the second switch selectively routing the data destined for the first selected pin therethrough in lieu of the serial signal.
- 17. The apparatus of claim 15, wherein the first switch to provide the scrambled data stream directly to the PCMCIA connector if a PCMCIA card is inserted into the slot and is coupled to the PCMCIA connector in lieu of the adapter and the smart card.
- 18. The apparatus of claim 15 further comprising:a second switch coupled to the second converter to receive either the descrambled serial data stream from the second converter when the adapter is inserted into the first slot and coupled to the PCMCIA connector or the descrambled serial data stream directly from the PCMCIA connector when a PCMCIA card is inserted into the first slot.
- 19. An adapter adapted for insertion into a card slot associated with a conditional access module, comprising:a slot located at a first end, the slot being adapted to receive a smart card for establishing an electrical connection with the inserted smart card; a converter to convert a serial signal from the smart card to a parallel signal; a connector located at a second end of the adapter, the connector to connect the smart card to the conditional access module; and a smart card interface to convert an incoming parallel signal from the conditional access module into a serial signal corresponding to the incoming parallel signal.
- 20. The adapter of claim 19, wherein the connector is a PCMCIA connector.
- 21. The adapter of claim 20, wherein the smart card supporting a NRSS-A communication protocol.
- 22. The adapter of claim 19, wherein the electrical connection is achieved via at least one ISO contact of the inserted smart card.
