【摘要】：近年來,電子、微電子技術(shù)發(fā)展日新月異,嵌入式設(shè)備越來越多的出現(xiàn)在社會生活的各個領(lǐng)域。隨著嵌入式設(shè)備硬件性能的不斷提升、軟件技術(shù)的不斷發(fā)展、網(wǎng)絡(luò)覆蓋范圍的擴大和建設(shè)成本的降低,人們對電子設(shè)備的需求已不僅僅局限于文字、圖片和聲音,網(wǎng)絡(luò)和視頻已經(jīng)成為現(xiàn)代人生活不可缺少的一部分。因此,具有多功能和高性能的民用消費產(chǎn)品不斷涌現(xiàn)出來。目前視頻技術(shù)已廣泛地應(yīng)用在遠程教育、遠程醫(yī)療、視頻會議、在線直播、視頻電話和航空航天等多個行業(yè),視頻技術(shù)已經(jīng)成為社會發(fā)展不可缺少的推動力。嵌入式視頻服務(wù)器將嵌入式設(shè)備與視頻技術(shù)相結(jié)合,可為各應(yīng)用終端提供實時的視頻服務(wù),同時也降低了設(shè)備成本,擴大了使用范圍。 本文致力于嵌入式視頻服務(wù)器關(guān)鍵技術(shù)的研究。闡述了國內(nèi)及國外視頻監(jiān)控技術(shù)的發(fā)展現(xiàn)況、發(fā)展趨勢以及本課題的研究背景及意義。研究了嵌入式系統(tǒng)硬件開發(fā)平臺、嵌入式Linux開發(fā)環(huán)境、AAC、MP3和H.264等音視頻編碼壓縮算法和RTSP/RTP/RCP等網(wǎng)絡(luò)協(xié)議。提出了嵌入式視頻監(jiān)控服務(wù)器系統(tǒng)的設(shè)計方案,并詳細介紹了交互協(xié)議、音視頻信息的采集、視頻編碼壓縮、音視頻數(shù)據(jù)打包、音視頻數(shù)據(jù)發(fā)送、定時錄像功能和網(wǎng)絡(luò)客戶端音視頻播放組件的設(shè)計與實現(xiàn)等關(guān)鍵技術(shù)。 論文的最后一章,針對嵌入式視頻監(jiān)控服務(wù)器的研究工作進行了總結(jié),并為后續(xù)工作提出了展望和建議。
[Abstract]:In recent years, with the rapid development of electronic and microelectronic technology, embedded devices appear more and more in various fields of social life. With the continuous improvement of hardware performance of embedded devices, the development of software technology. With the expansion of network coverage and the reduction of construction costs, people's demand for electronic devices is not limited to text, pictures and sound, network and video has become an indispensable part of modern life. Currently, video technology has been widely used in distance education, telemedicine, video conferencing, live online. Video technology has become an indispensable driving force for social development in many industries such as video telephony and aerospace. Embedded video server combines embedded devices with video technology. It can provide real-time video service for all application terminals, reduce the cost of equipment and expand the scope of use. This paper is devoted to the research of the key technology of embedded video server, and expounds the current situation of the development of video surveillance technology both at home and abroad. The development trend and the research background and significance of this subject. The embedded system hardware development platform, embedded Linux development environment is studied. MP3 and H.264 audio and video coding compression algorithms and network protocols such as RTSP/RTP/RCP. The design of embedded video surveillance server system is presented, and the interactive protocol is introduced in detail. The key technologies are the acquisition of audio and video information, the compression of video coding, the packaging of audio and video data, the sending of audio and video data, the function of timing video recording and the design and implementation of audio and video playback components of network client. In the last chapter of the paper, the research work of embedded video surveillance server is summarized, and the future work and suggestions are put forward.
