A system and method for effectively determining a current physical location of a remote control device includes a television device that is configured to receive television control information over an RC-TV communications link. The remote control device transmits the device control information over the RC-device communications link for controlling various functions of the television device. In situations in which the current physical location of the remote control device is unknown, a system user may initiate a location search procedure with a search trigger event to locate the remote control device. The remote control device then generates one or more location indicators in response to the search trigger event to thereby facilitate determining the current physical location of the remote control device.
