The number of notebooks built-in wireless devices and the number of meeting rooms equipped with projectors are increasing rapidly. However, a notebook wanting to show its screen by a projector has to be interconnected with the projector by a VGA cable. If there are two more presenters in a meeting, switching the VGA cable among them is a tedious work. Thus, the authors propose a wireless presentation system which uses wireless network instead of VGA cable to cut down the switching time. Although a large number of products have been made on this concept, little is known about having a good performance and quality. The aim of this paper is to design and implement a real time wireless presentation system capable of rendering full screen 20 times per second with resolution 800x600x16. In order to achieve the goal, the authors investigate into different methods and choose the most suitable one.
