Abstract:

In order to solve the problems that video image quality and transmission speed is low through mobile termination,combining the Android system development technology and H.264 video encoding method.At the base of extensive mobile internet technology,a new  video monitoring system is designed and implemented.Firstly,the method to transplant Android operating system to ARM（Advanced Risc Machines） platform and to collect video data based on ARM platform has been raised,then Android system architecture and start principle is analyzed,meanwhile,video encoding way of H.264 is baseline profile,the average PSNR(Peak Signal to Noise Ratio) reaches 38.210 dB,encoding frame rate reaches 136.66 frames/s,compared with main profile and high profile,the baseline profile has much higher encoding frame rate,realtime and stable video monitoring effect is implemented.
