Abstract
A control device signals user inputs to an audio-video display. The control device may be configured as a pillow speaker and include a speaker for reproducing audio from the audio-video display. The control device is coupled to the audio-video display by wiring. Shared signals in the wiring are used to provide power to operate the control device and are used to signal the user inputs to the audio-video display. A touch panel is used to sense user inputs. The touch panel may be transparent with an underlay containing indicia of user-selectable commands located below the touch panel. The arrangement and selection of commands available to the user may be modified by changing the underlay.
