Abstract: An instant wireless touch screen control system for a smart television includes a smart set-top box, a wireless router and a wireless touch screen device. The smart set-top box is electrically connected to the router and the television to fetch an image displayed on the television, and further wirelessly transmits to the wireless touch screen device through the router. The wireless touch screen device transforms the received image from the router into a touch screen image based on some specific algorithm. The user can select and touch one of the icons or items in the touch screen image to generate a touch control signal, transmitted to the smart set-top box through the router. The smart set-top box generates and transfers an image control signal based on the touch control signal to the television, which displays the selected item and performs the preset function corresponding to the image control signal.
