【摘要】：隨著經(jīng)濟(jì)的快速發(fā)展以及大眾生活水平日益提高，人們對(duì)安防產(chǎn)品的需求也越來(lái)越高。傳統(tǒng)的模擬視頻監(jiān)控系統(tǒng)由于存在安裝時(shí)間較長(zhǎng)、破壞原有家庭裝修、視頻信息時(shí)效性較低等不足，已經(jīng)逐漸無(wú)法滿足人們的要求。因此，，流媒體技術(shù)和嵌入式技術(shù)的不斷發(fā)展、移動(dòng)終端尤其是智能手機(jī)的不斷普及，使得基于無(wú)線網(wǎng)絡(luò)和嵌入式技術(shù)的無(wú)線監(jiān)控逐漸取代傳統(tǒng)的監(jiān)控方式，在諸如校園安全、居家安全、城市交通、重要安全部門(mén)等各個(gè)領(lǐng)域得到廣泛的應(yīng)用。 目前，國(guó)內(nèi)外已有很多視頻監(jiān)控系統(tǒng)在投入使用，如全球眼系統(tǒng)、天翼看家等。雖然此類(lèi)現(xiàn)有的視頻監(jiān)控系統(tǒng)，可以實(shí)現(xiàn)用戶通過(guò)監(jiān)控終端查看現(xiàn)場(chǎng)視頻的功能，但也存在一些不足：市場(chǎng)上監(jiān)控設(shè)備品種繁多，而各廠家都有與自己監(jiān)控設(shè)備SDK相匹配的數(shù)據(jù)傳輸協(xié)議，沒(méi)有統(tǒng)一的視頻播放系統(tǒng)，導(dǎo)致市場(chǎng)混亂，視頻源兼容性差；移動(dòng)終端尤其是智能手機(jī)終端未能自適應(yīng)地訪問(wèn)多種協(xié)議視頻源，不能實(shí)現(xiàn)移動(dòng)視頻監(jiān)控或播放。 鑒于此，本文通過(guò)研究智能移動(dòng)終端和視頻監(jiān)控的關(guān)鍵技術(shù)，提出了一種基于Android平臺(tái)的視頻監(jiān)控多協(xié)議客戶端，該客戶端為智能手機(jī)終端，支持多協(xié)議視頻源的播放，簡(jiǎn)化了用戶使用多個(gè)廠家的視頻監(jiān)控設(shè)備（攝像機(jī)）必須安裝多個(gè)視頻驅(qū)動(dòng)程序的復(fù)雜部署，實(shí)現(xiàn)移動(dòng)終端對(duì)多種不同協(xié)議的視頻源的自適應(yīng)識(shí)別和播放，提高系統(tǒng)的視頻播放性能和視頻源兼容性。此外，本系統(tǒng)還通過(guò)兼容RTMP協(xié)議的視頻源，解決了現(xiàn)有的Android系統(tǒng)和IOS系統(tǒng)未支持基于RTMP的Flash格式視頻播放功能的問(wèn)題，使得作為優(yōu)秀的視頻播放類(lèi)型文件Flash除了可以在瀏覽器網(wǎng)頁(yè)上播放，同樣在安裝有Android系統(tǒng)或IOS系統(tǒng)的移動(dòng)終端上播放。 本文中提出的基于Android平臺(tái)的網(wǎng)絡(luò)多協(xié)議視頻監(jiān)控系統(tǒng)，經(jīng)實(shí)驗(yàn)證明，可以適配不同廠家的視頻監(jiān)控設(shè)備，在移動(dòng)終端上自動(dòng)播放多協(xié)議視頻，使得移動(dòng)視頻監(jiān)控更具便利性，向標(biāo)準(zhǔn)化發(fā)展，為人們的生活帶來(lái)極大的便利。
[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.
