A method for control comprises a set top box receiving coordinates from a touch sensing screen. The coordinates are interpreted for controlling the set top box, and in accordance with the interpreted coordinates an action is performed. A further method for control comprises a set top box receiving a signal representative of displacement. A control function is determined from the displacement representative signal and the control function is activated. In accordance with the control function a signal is formed for communication.
Its a 2D/3D input system for a set top box from something like a touch sensitive RCU, or more likely a media device. The trick to the patent seems to be that the video from the set top box is used as the rendering of the user interface for the input device. That is, the touch sensitive input device does not render a user interface itself but takes a video stream and displays it. The video stream from the set top box already has the user interface rendered into it. The user then uses normal touch or stylus input and these co-ordinates are transmitted back to the set top box where some smart software converts those co-ordinate inputs into commands for the set top box (which may have more traditional form of input).
Here is a diagram:
Nice.
