摘要 |
A radio frequency controlled system (10,20,30) is described in which a user's remote control (30) having a unique identifier is only accepted by a device (10, 40a) to enable remote control if authenticated. The authentication process causes the device (10, 40a) to generate and issue a key sequence which the user must input. Commands from a remote control unit (30) having the identifier are only accepted if the key sequence has been previously, and correctly input. The key sequence is issued so that only a user in close proximity of the device with direct line of sight/hearing can input it on the device. Hence, inadvertent control by a neighbours' radio frequency remote control unit is eliminated. The invention is described employing the ZigBee radio standard. |
