VNC (virtual network computing) is a popular tool for sharing an application, allowing users to access graphic displays remotely. In mobile VNC systems, it has been challenging to increase screen update rate by fast screen image encoding. In this paper, we implement a prototype system for mobile VNC, and several works are done for improving screen update rate. At first, a number of video encoders are integrated into a prototype system, and we investigate what is the most suitable codec for mobile VNC. The existing RFB protocol is extended straightforwardly to integrate video codecs. Next, the overall system architecture is modified from serial operation to parallel. Finally, we propose a modified region coding to further reduce the encoding time of screen images. The proposed methods are implemented into our prototype mobile VNC system, and practical performances are widely evaluated. We report that JPEG is the most suitable for mobile VNC in terms of both complexity and compression ratio. In addition, the proposed modified region coding can decrease encoding time, and consequently increase screen update rate 1 .

We present an automatic embedded projector player system with wireless network. Embedded system substitutes for the personal computer system, the latter usually plays role of player for projector nowadays. The player system solves the problem of cable complex layout of projector by using the wireless network. We also recommend a new remote control handle with wireless network and USB storage port, which can read files from flash disk and upload these files to player system, and can operate the player system of projector completely. It has advantages of no PC, low cost, low power consumption, and high convenient. This paper gives the hardware and software architecture of the player system, and discusses the design in detail. At last, we show a prototype, and experiments were demonstrated the validity of the proposed system.
