Mapping visual display screen to portable touch screen

摘要

A content player transmits a screen image to a display. The screen image includes an active region, which may be a portion that may be manipulated. The player determines active region information for the active region and transmits such to a portable device. The portable device receives the active region information as well as information regarding any inactive regions, which may be portions that may not be manipulated. The portable device utilizes the information to present a simulated version of the screen image on a touch screen. The portable device may then receive manipulation information via the touch screen and transmit such to the player. In response, the player may generate and present an updated version of the screen image, determine updated information, and transmit such to the portable device. The portable device may utilize the updated information to present a simulated updated version of the screen image.
