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 system comprising:

at least one server configured to receive signals from at least one remote control device and including a radiofrequency identification (RFID) transceiver and at least one non-RFID transceiver for communicating with the respective RFID and non-RFID elements of a component, the server;

receiving a key and device configuration information from the component by RFID;

sending a message to the component requesting a response;

receiving a response from the component;

establishing a non-RFID link with the component;

receiving an encrypted message from the component over the non-RFID link, the encrypted message including at least the same device configuration information received from the component by RFID;

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

in response to determining that the device configuration information received from the component by RFID is identical to the device configuration information received over the non-RFID link, registering the component with a network; and

in response to determining that the device configuration information received from the component by RFID is not identical to the device configuration information received over the non-RFID link, refusing registration of the component with the network.

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

3. The system 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 system of claim 1, wherein component information from the component necessary for the remote control device to control the component is provided to the remote control device automatically over at least one network path associated with the system to eliminate the need to manually program the remote control device with the component information and at least a portion of the network path is an RFID path, the 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 system of claim 1, wherein at least a portion of the network path is an RFID path, the 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 the remote control device.

6. The system of claim 1, wherein the 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 the remote control device.
