摘　　要：提出了一种基于Android平台的视频监控系统方法。阐述了系统的结构框架,介绍了An-droid操作系统及其应用层的开发,重点描述了PDA端视频处理的实现。系统采用Blackfin533芯片实现对视频的H.264编码,并应用快速模式选择算法优化编码过程,可使通信模块和数据处理模块通过Android平台代码完成。在3G无线网络环境下,实现了后台对远端的实时视频监控。测试表明,延迟可控制在5 s以内。An idea and program of video monitoring system based on Android is presented.This paper introduces the system ar- chitecture and Android operating system and development of application layer.It emphatically discusses the ideas and methods of PDA video processing.It uses Blackfin533 for H.264 data decoding and fast mode selection algorithm for optimal coding, The com- munication module and data processing module are realized through the Android platform code. It achieves the remote real-time video surveillance from backstage in 3G wireless networks.Through testing, the delay is controlled in less than 5 seconds.
