Definitions
- the present invention relates to interfaces in a system using integrated circuit (IC) cards. More particularly, the invention relates to a method and apparatus for supporting two different IC card standards using a single IC card connector.
- IC integrated circuit
- Integrated circuit (IC) cards such as smart cards, are used in a variety of consumer electronics devices, including pay TV systems, set top cable television boxes, terrestrial television receivers, satellite television receivers and the like.
- Two types of IC card are based upon the ISO/781 6 standard for conventional IC cards and the NRSS standard for IC cards having high-speed data transfer ports.
- the current IC card systems comprise a connector that is capable of supporting (or operating as an interface to) only one type of IC card.
- a connector capable of supporting an ISO/781 6 card cannot support a NRSS card, and vice versa.
- the IC card system would require an additional IC card connector. Therefore, a need exists for an IC card interface capable of supporting ISO/781 6 and NRSS cards with a single connector.
- the invention overcomes the disadvantages associated with the prior art by providing a method and apparatus capable of receiving ISO/781 6 and NRSS cards with a single connector.
- the apparatus is a computer-controlled device comprising a card reader that further comprises an interface controller and a connector.
- the connector which comprises eight pins, forms an interface between the computer controlled device and eight corresponding contacts of the IC card, i.e., contacts C1 through C8.
- the interface controller determines whether the IC card inserted into the card reader is an ISO/781 6 or NRSS card and provides the correct interface for the IC card.
- an interface controller sends a test signal to the input/output contact (C7) of the IC card and detects this contact (C7) to determine whether the IC card sends a reply or answer signal in response to the test signal.
- the test signal is selected such that one type of IC card replies to the test signal, while the other type of IC card responds differently, e.g., is non-responsive, to the test signal.
- the interface controller implements the correct interface for the detected IC card.
- the interface may comprise buffers and pull-up resistors. Buffers block selected signals in the connectors (associated with contacts C4, C6 and C8) unless enabled by the interface controller.
- the interface controller detects the IC card as a NRSS card, then the interface controller sends a "buffer enable" signal to the buffers.
- Pull-up resistors are coupled to connectors associated with selected contacts (C4, C6 and C8) on the IC card, in case the IC card is a NRSS card.
- the inventive method comprises the steps of determining whether an IC card is an ISO/781 6 or NRSS card and implementing an interface for the identified IC card.
- the determining step further includes the steps of applying a test signal to the IC card and identifying whether the IC card transmits a reply signal in response to the test signal.
- the implementing step may include blocking or enabling a buffer such that signals are transmitted to selected contacts of one type of IC card (i.e., a NRSS card) and blocked to selected contacts of the other type of IC card (i.e., an ISO/781 6 card) .
- FIG . 1 depicts a block diagram of an integrated circuit (IC) card system including a IC card interface that operates in accordance with the present invention
- FIG. 2 depicts an assignment of signal contacts on a IC card
- FIG. 3 depicts a flow diagram showing the operation of the present invention.
- FIG. 1 depicts an integrated circuit (IC) card system 1 00 comprising an IC card 1 02 and a computer controlled device 1 04.
- the IC card 1 02 is typically a smart card, an access card or a memory card for enabling the computer- controlled device 1 04 to operate a computer controlled system 1 06.
- the IC card 1 02 comprises a card controller 1 08 and a card memory 1 1 0.
- the card controller 1 08 coordinates signal and data transfer between the card memory 1 1 0 and the computer controlled device 104.
- the IC card 1 02 includes an arrangement of contacts that generally comply with either the conventional ISO/781 6 standard or the NRSS standard for high-speed data transfer. Variations of the ISO/781 6 and NRSS cards are contemplated within the scope of the invention.
- the computer-controlled device 1 04 generally includes any device that operates a computer-controlled system 1 06 upon receipt of the IC card 1 02. Examples of such computer-controlled devices 1 04 include a direct broadcast satellite television system, set top cable television boxes for cable and video-on- demand systems, high definition television system, terrestrial television receivers, satellite television receivers and other similar devices.
- the computer-controlled device 1 04 comprises a computer-controlled system 1 06, a microcontroller 1 1 2, a memory 1 1 4 and a card reader 1 1 6.
- the microcontroller 1 1 0 is a processor that retrieves and executes a card reading software or routine 300 from the memory 1 1 4, instructs the card reader 1 1 6 to detect the IC card 1 02 received therein, and activates the computer controlled system 106 upon an acknowledgement from the card reader 1 1 6.
- the computer-controlled system 1 06 is a system or module that operates the IC card system 1 00 in response to a signal from the microcontroller 1 1 2.
- the memory 1 14 stores the card reading routine 300 or method, as well as other applications for implementing the IC card system 1 00.
- the card reader 1 1 6 couples the IC card 1 02 to the computer-controlled device 1 04 at an interface 1 1 8.
- the card reader 1 1 6 comprises a connector 1 20 and an interface controller 1 22.
- the connector 1 20 comprises eight pins that form the interface 1 1 8 between the interface controller 1 22 and the IC card 1 02. If the pins are coupled to the contacts of the IC card 1 02, then these pins form conductive paths for transmitting or receiving signals and data through the interface 1 1 8.
- the card reader 1 1 6 comprises a buffer 1 24 and a resistor 1 26 for further defining the interface 1 1 8.
- the signals and data at the interface 1 1 8 are typically assigned to the contacts of the ISO/781 6 and NRSS cards as depicted in FIG. 2.
- Five of the contacts have the same assigned signals for the two types of IC cards 1 02 depicted, namely: supply voltage, reset signal, clock signal, ground and data input/output.
- Another contact typically the sixth contact (C6) of the IC card 102, is assigned to a programming signal for the ISO/781 6 card and a NRSS clock signal for the NRSS card.
- the two remaining contacts, typically the fourth and eighth contacts (C4 and C8) on the IC card 102, are undefined for ISO/781 6 cards, but represent high speed data input and output paths on NRSS cards.
- the buffer 1 24 is coupled to the interface controller 1 22 and the pins of the connector associated with contacts C4, C6 and C8 of the IC card 1 02. Specifically, the buffer 1 24 may block or disable the conductive path to and from the contacts C4, C6 and C8. If the buffer 1 24 receives a "buffer enable" signal from the interface controller 1 22, then the buffer 1 24 enables the conductive path between the interface controller 1 22 and contacts C4, C6 and C8 of the IC card 1 02.
- the resistor 1 26 is coupled to a supply voltage, typically 5 volts, as well as to the pins of the connector associated with contacts C4, C6 and C8 of the IC card 1 02. If the buffer 1 24 blocks the conductive path to and from these contacts C4, C6 and C8, the pins associated with these connector are "pulled up” to the supply voltage. In this case, the supply voltage drives the contacts C4, C6 and C8.
- the pull up resistor 1 26 is generally of high resistance, such that the effect on the conductive path is minimal when the buffer 1 24 is enabled, i.e., a "weak" pull-up.
- the interface controller 1 22 is a processor that determines whether the IC card 1 02 is an ISO/781 6 or NRSS card. The interface controller 1 22 performs this determination while the microcontroller executes the routine or method 300. Once the correct IC card 1 02 is determined, the interface controller 1 22 implements the correct interface 1 1 8 for the ISO/781 6 or NRSS card 1 02. The steps for determining the type of IC card 1 02 and implementing the correct interface for the IC card 1 02 are described with respect to FIG. 3.
- FIG. 3 depicts a flow diagram of the routine or method 300 used in the present invention. Specifically, the microcontroller 1 1 2 executes the method 300 and the interface controller 1 22 implements the method 300 for determining whether the received IC card 1 02 is an ISO 781 6 or NRSS card. Once the IC card 1 02 is inserted into the card reader 1 1 6, the method
- step 302. the method 300 assumes that the received IC card 1 02 is an ISO/781 6 card.
- the buffers 1 24 are disabled for blocking the conductive path to and from contacts C4, C6 and C8 of the IC card 1 02.
- the pins associated with these contacts are pulled up to the supply voltage.
- the method 300 instructs the interface controller 1 22 to apply a test signal or a reset signal to contact C7 on the IC card 1 02.
- the test signal is selected such that the card controller 108 in one type of IC card 1 02 responds to the test signal, whereas the card controller 1 08 in the other type of IC card 1 02 responds differently, e.g., is non-responsive, to the test signal.
- the test signal or reset signal may elicit a response from the ISO/781 6 card and no response from the NRSS card.
- the interface controller 1 22 determines whether the received
- IC card 1 02 is a NRSS card. Specifically, the interface controller 1 22 determines whether the card controller 1 08 of the IC card 1 02 transmits a reply signal on contact C7. If the selected test or reset signal elicits a response from only an ISO/781 6 card, the interface controller 1 22 checks for the absence of a reply signal from the IC card 1 02.
- step 31 0 the interface controller 1 22 implements an interface 1 1 8 for the NRSS card.
- the interface controller 1 22 sends buffer enable signals to the buffers 1 24.
- the interface controller 1 22 may transmit NRSS input data and NRSS clock signals to contacts C4 and C6, and receive NRSS output data from contact C8 of the NRSS card.
- step 31 2 the interface controller 1 22 implements an interface 1 1 8 for the ISO/781 6 card.
- the buffers 1 24 continue to disable the conductive paths to and from contacts C4, C6 and C8 of the ISO/781 6 card.
