This paper describes a compact display system with a network interface to receive video signals from a server. This system has been built on a small digital circuit board with an integrated DSP&CPU chip and embedded in our prototype portable projector. The network interface is made detachable by using a network adaptor on a USB port. This architecture makes it highly configurable and easy to change its functions according to customers' needs.
