The Design And Implementation Of Video Surveillance System Based On Mobile Terminals

In recent years, with the improvement of technology, the development of Internet bandwidth and the rise of mobile Internet, the Internet media carrier has undergone significant changes. In the past, because of network bandwidth, network media mainly consists of text, still pictures and a few of audio. Now, video is becoming a mainstream form of Internet media carrier. Compared with text, still pictures and audio media, video media is vivid and has large amount of information. Thus, stream video has been widely applied in distance education, telemedicine, video conferencing, online broadcasting, video phones, aerospace and other fields.This thesis proposes a video surveillance system based on mobile terminals. The system uses a Client-Server(C / S) architecture, consisting of a stream server and stream clients. In stream server, a new program of stream server based on embedded Linux operating system is presented after researching embedded Linux platform, H.264 video encoding algorithm and RTP/RTCP, which consists of video capturing subsystem, video encoding subsystem and video transmitting subsystem. And the program run at stream clients based on Android achieves the real-time stream video decoding and playback using JNI supplied by Android.The experiment shows that the proposed video surveillance system based on mobile terminals achieves real-time video stream decoding and playback on mobile devices and lays a foundation of expanding the scope of application in the future.
