Abstract
A video delivery system includes a tablet computer and one or two detachable projectors. In one embodiment, video files are transferred from the tablet computer to the projectors when they are connected. The tablet computer is used as a remote control that controls an operation of delivering a video portion of the video file through the projectors and an audio portion through the tablet computer in a synchronized manner. In one aspect, the two projectors may be positioned to project two adjacent screens that present different portions of images. In another embodiment, positions of the projectors attached to the tablet computer may be adjusted to deliver desired screens.
