Video is a good communication tool, and a video broadcasting system can deliver some screen contents to some computers to show. There are currently many video broadcasting products and applications, such as projectors, video learning systems, and video streaming systems, but they are either hardware implementations or non real-time implementations. Additionally, almost all of them do not well support a one-to-many model. To solve above problems, a novel software-based approach capable of rendering full screen 20 frames per second under 800×600×16 resolution to one or two more computers is proposed in this paper. Different methods are investigated and the most suitable one chosen to achieve this goal. In addition, this system is currently applied to wireless projector systems and video learning systems.
