CONTROL OF LARGE SCREEN DISPLAY USING WIRELESS PORTABLE COMPUTER TO PAN AND ZOOM ON LARGE SCREEN DISPLAY

摘要

A multi-window user interface (UI) on a control device such as a tablet computer communicates commands to a display controller, which may be implemented by a game console. The controller controls presentation on a large screen display according to the commands. The control device may always present a multi-window UI which the control device can command to have mimicked on the display, with the UI also being configured to cause a single video to be presented whole screen on the display while the multi-window UI remains presented on the control device. The video feeds that populate the multi-window UI are of the same content but of lower resolution than those which are presented on the display. A movable window on the control device can be dragged and dropped to cause a corresponding magnifying focus on the display over the corresponding portion of video in focus on the control device.
