Yan Ze-qiu

Abstract

The design of a wireless video transmission system based on S3C2440A and embedded Linux OS is presented,it mainly introduces structure of the system and functions of the key modules,such as hardware design of video capturing and wireless video transmission modules,implement of the driver transplantation based on Linux,MPEG-4 digital video software encode and the application program software.The video transmission based on WLAN and this system has been realized,real-time monitoring network data flow and congestion conditions,controlling the video compression ratio automatically,improving the network transmission quality,ensuring the fluency of video playing.High reliability and convenient usage are achieved.
