Abstract

A feasible and novel design and implementation scheme of embedded video surveillance system, which is based on improved H.264 and Wi-Fi, is proposed in this paper. A video server, built on an ARM11 platform with a wide range of peripheral interface, is responsible for capturing image data using Video for Linux Two API, provided by the kernel, with a USB camera. The compressed video data encoded by X264 library is transmitted to clients through RTP protocol and Wi-Fi wireless network. Based on in-depth examination about UMHexagonS, the fast motion estimation algorithm for H.264/AVC, two improvements are proposed and implemented in the X264 used in this system to further improve coding efficiency. On the client side, the encoded data is firstly saved for future use and then decoded using FFmpeg to get the raw data, which should be conducted format conversion in order to be displayed using GTK on the screen. The experimental results indicate that the embedded system runs stably, have higher speed and is cost-effective and small in size, all these merits making it significant in practical use.
