N2 - Wireless video transmission on smart phone platform like Android is facing difficulties as lack of real-time program mechanism, inconsistent quality of the wireless network, and etc. To improve video transmission quality on Android, this paper proposes a viable video QoS scheme with a system level realization. To reduce the response time, we did the optimizations on Linux operating system level without using Android video system, and the interfaces were provided to upper-layer applications. To reduce the time delay of capturing and playing video, we sped up interrupt response, decompressed the captured video data in user space. To reduce the influences of unstable wireless network and minimize the end-to-end delay, we adapted dynamic video encoding rates control, and to control packet loss ratio, we used a buffer management policy. We had conducted a series of experiments to validate this scheme. The results show that the response time and the quality of video transmission have been significantly improved.
