Abstract

This invention is a Bluetooth-enabled remote control device that uses standard Bluetooth built-in techniques to discover devices around the house. Once a device is detected, its protocol information can be exchanged and registered with the remote. Thus, no manual programming is required. To help ensure that only those in the home can control their Bluetooth-enabled devices via remote, the user can press a button on the device itself to add its protocol information and register it with the remote. This Bluetooth-only method gives the added advantage that one does not need line of sight as with Infrared (IR) to control a device. This is especially useful for controlling devices in other rooms of the house, like an oven, stereo, or thermostat. The remote control would probably also contain the existing IR technology to allow it to control legacy IR devices.

  Universal remote control with Bluetooth-based advanced device detection and control

   In order to add a new device to be controlled by a Bluetooth-enabled remote control device, the user will:

Select the name of the new device that has been discovered by the remote control

(this could be done via either an LCD display on the remote, or a "known" TV set could be used for display to eliminate the need/cost of having an LCD display on the remote). Then simply press a button on the device itself to automatically add this device's

protocol information and register it with the remote. After registration, the remote can control the device.

The remote can now lock the device in a mode that will not allow for another remote

device to register it. This is out of consideration for apartment building dwellers who are in close enough proximity to Bluetooth-detected devices in neighboring apartments.

Once a device is registered, an LCD display on the remote (or TV as mentioned above) will display the list of devices. The user can select a device from the list and the remote would then be used to control the device. In addition to having a simple list of devices, the remote will also provide for a quicker device selection by learning which devices are subordinate to which others. For instance, a set-top box or VCR may be considered to be a subordinate device to a TV, because if the TV is not powered on the other devices are not useful. Once a device is determined to be subordinat...
