低速率的无线视频监控系统设计与实现

Design and Implementation of Low Bit-rate Wireless Video Surveillance System

随着低速率的视频编码技术与无线通信技术的迅速发展,使得为用户提供移动视频监控业务成为可能。这里,文章实现了一套在移动环境下的实时视频监控系统。该系统融合了H.264视频编码技术,并对H.264核心代码进行了优化,以确保其在处理能力较弱的移动终端上流畅解码。实验表明,即使在低速率的无线网络环境下,也可以获得较高质量的监控图像。

With the rapid development of video coding technology and wireless communication technology of low rate, it is possible to provide users with mobile video surveillance service. In this paper a real-time video surveillance system under mobile environment is designed, the system integrates the H.264 video codec technology, and the H.264 core code is optimized, so as to ensure its smooth decoding in the mobile terminal processing capability being weak. Experiments show that even in low bit-rate wireless network environment, high quality surveillance images.
