Abstract

Control information is exchanged between a component and a remote control device or a server using RFID or using network discovery procedures. The control information if gathered by the server is provided to the remote. In this way, the need to manually program the remote with component code information is eliminated.

Claims

1. A method comprising:

receiving configuration information from a home network component by radiofrequency identification (RFID);

establishing a non-RFID link with the component;

receiving the configuration information from the component over the non-RFID link;

comparing the configuration information received by RFID with the configuration information received over the non-RFID link;

in response to determining that the configuration information received by RFID matches the configuration information received over the non-RFID link, permitting the component to communicate with at least one node in a network; and

in response to determining that the configuration information received by RFID does not match the configuration information received over the non-RFID link, not permitting the component to communicate with the at least one node in the network.

2. The method of claim 1, wherein the component is a camera.

3. The method of claim 1, wherein the component is a DVD player or PVR or set-top box or personal computer or CD/MD player/recorder.

4. The method of claim 1, wherein at least a portion of the communications path is an RFID path, a remote control device having a remote RFID reader/writer and the component having a component RFID assembly carrying the component information for reading thereof by the remote control device.

5. The method of claim 1, wherein at least a portion of the communications path is an RFID path, a server having a server RFID reader/writer and the component having a component RFID assembly carrying the component information for reading thereof by the server, the server sending the component information to a remote control device.

6. The method of claim 1, wherein a server communicates with the component over a home network, the server obtaining the component information automatically by means of network discovery protocol and providing the component information to a remote control device.

7. A home network, comprising:

at least one server having at least one radiofrequency identification (RFID) element;

at least one remote control device wirelessly inputting signals to the server using RFID received by the RFID element of the server;

the server comparing the signals received from the remote control device through the RFID element with signals received over a non-RFID communication link and responsive to the comparison determining whether to grant a component access to the home network.

8. The network of claim 7, wherein the component is a camera.

9. The network of claim 7, wherein the component is a DVD player or PVR or set-top box or computer or CD/MD player.

10. The network of claim 7, wherein the remote control device has a remote RFID reader/writer and the component has a component RFID assembly carrying the component information for reading thereof by the remote control device to establish the means for automatically providing.

11. The network of claim 7, wherein the server communicates with the component over a home network path, the server obtaining the component information automatically by means of network discovery protocol and providing the component information to the remote control device to establish the means for automatically providing.

12. A system comprising:

at least one server having a server RFID component; and

at least one component having a component RFID component, the server and component exchanging an encryption key and/or information necessary to generate the encryption key using a RFID link between the RFID components and subsequently encrypting at least some communication using the encryption key for transmission of the communication over a non-RFID link at least in part responsive to a comparison of information received over the RFID link with information received over the non-RFID link.
