Abstract

Various embodiments of systems, methods and apparatus are provided for changing an operational mode of a remote control for a controlled device. A remote control queries a controlled device to determine the operating state of the controlled device. Responsive to determining the operating state of the controlled device, the remote control determines whether to enter an active mode state and/or limited power mode state. Components of the remote control may then be commanded to enter a selected operating mode state depending on whether the components are utilized by the present operational state of the controlled device.
