【摘要】：随着经济的快速发展以及大众生活水平日益提高，人们对安防产品的需求也越来越高。传统的模拟视频监控系统由于存在安装时间较长、破坏原有家庭装修、视频信息时效性较低等不足，已经逐渐无法满足人们的要求。因此，，流媒体技术和嵌入式技术的不断发展、移动终端尤其是智能手机的不断普及，使得基于无线网络和嵌入式技术的无线监控逐渐取代传统的监控方式，在诸如校园安全、居家安全、城市交通、重要安全部门等各个领域得到广泛的应用。目前，国内外已有很多视频监控系统在投入使用，如全球眼系统、天翼看家等。虽然此类现有的视频监控系统，可以实现用户通过监控终端查看现场视频的功能，但也存在一些不足：市场上监控设备品种繁多，而各厂家都有与自己监控设备SDK相匹配的数据传输协议，没有统一的视频播放系统，导致市场混乱，视频源兼容性差；移动终端尤其是智能手机终端未能自适应地访问多种协议视频源，不能实现移动视频监控或播放。鉴于此，本文通过研究智能移动终端和视频监控的关键技术，提出了一种基于Android平台的视频监控多协议客户端，该客户端为智能手机终端，支持多协议视频源的播放，简化了用户使用多个厂家的视频监控设备（摄像机）必须安装多个视频驱动程序的复杂部署，实现移动终端对多种不同协议的视频源的自适应识别和播放，提高系统的视频播放性能和视频源兼容性。此外，本系统还通过兼容RTMP协议的视频源，解决了现有的Android系统和IOS系统未支持基于RTMP的Flash格式视频播放功能的问题，使得作为优秀的视频播放类型文件Flash除了可以在浏览器网页上播放，同样在安装有Android系统或IOS系统的移动终端上播放。本文中提出的基于Android平台的网络多协议视频监控系统，经实验证明，可以适配不同厂家的视频监控设备，在移动终端上自动播放多协议视频，使得移动视频监控更具便利性，向标准化发展，为人们的生活带来极大的便利。
[Abstract]:With the rapid development of economy and the improvement of people's living standard, people's demand for security products is higher and higher. The traditional analog video surveillance system has been installed for a long time and destroyed the original home decoration. Therefore, with the development of streaming media technology and embedded technology, mobile terminals, especially smart phones, are becoming more and more popular. Wireless monitoring based on wireless network and embedded technology has gradually replaced the traditional monitoring methods, and has been widely used in many fields such as campus security, home security, urban traffic, important security services and so on. At present, many video surveillance systems have been put into use at home and abroad, such as global eye system, skywing housekeeping system and so on. Although this kind of existing video surveillance system can realize the function that users can view live video through monitoring terminal, But there are also some shortcomings: there are many kinds of monitoring equipment in the market, and each manufacturer has the data transmission protocol matching with their own monitoring equipment SDK, there is no unified video playback system, which leads to market confusion and poor compatibility of video source; Mobile terminals, especially smart phone terminals, can not access multiple protocol video sources adaptively and can not monitor or play mobile video. In view of this, by studying the key technologies of intelligent mobile terminal and video surveillance, this paper proposes a multi-protocol client of video surveillance based on Android platform, which is a smart phone terminal and supports the playback of multi-protocol video source. It simplifies the complex deployment of multiple video drivers that the user must install using the video surveillance equipment (camera) of many manufacturers, and realizes the adaptive recognition and playback of video sources of various protocols by mobile terminals. In addition, the system solves the problem that the existing Android system and IOS system do not support the Flash format video playback function based on RTMP through the video source compatible with RTMP protocol. As an excellent video playback type file, Flash can be played on browser pages as well as on mobile terminals with Android system or IOS system. The network multi-protocol video surveillance system based on Android platform proposed in this paper has been proved by experiments that it can adapt to different manufacturers' video monitoring equipment and automatically play multi-protocol video on mobile terminal, which makes mobile video monitoring more convenient. The development of standardization brings great convenience to people's life.
