摘  要

    數字視頻監控系統的客戶端的需求主要來自于遠程視頻監控，面對計算機和移動設備的普及，用戶已經不再滿足于只能在監控室或保安室里觀看查看監控視頻，用戶希望能隨時隨地地通過計算機和移動設備遠程地查看他們關心的監控視頻。為了滿足需求，數字視頻監控系統的客戶端已經成為了數字視頻監控系統中重要的組成部分。
 數字視頻監控系統是以數字視頻處理技術為核心，綜合利用光電傳感器、計算機網絡、自動控制和人工智能等技術的一種新型監控系統。與數字視頻監控系統相關的主要技術有視頻數據壓縮，視頻的分析與理解，視頻流的傳輸與回放和視頻數據的存儲。而數字視頻監控系統中的遠程監控客戶端則是使用現代計算機技術和現代網絡技術實現遠程實時視頻監控。
 本文介紹在HiRay公司基于TI DM365SoC的數字視頻監控系統上，使用Gstreamer框架實現數字視頻監控系統中客戶端軟件。

 Digital Video Surveillance System
Design and Implementation of the client
ABSTRACT
 
  Digital Video Surveillance System client demand mainly comes from the remote video monitoring, the face of the popularity of computers and mobile devices, users are no longer satisfied only in the control room or security room watching view the surveillance video, the user would like to anytime, anywhere computers and mobile devices through the remote to view the surveillance video they care about. To meet demand, digital video monitoring system client digital video surveillance has become an important part of the system.
 Digital video surveillance system is based on digital video processing technology as the core, comprehensive utilization of photoelectric sensors, computer networks, automatic control and artificial intelligence technology, a new monitoring system. Digital Video Surveillance System with the main technologies related to video data compression, video analysis and understanding of video streaming and video transmission and playback of data storage. The digital video surveillance system remote monitoring client is the use of modern computer technology and modern network technology for remote real-time video surveillance.
 This article describes the company based on TI DM365SoC in HiRay digital video surveillance systems, using the Gstreamer framework for digital video monitoring system client software.
Key words：Digital Video Remote Surveillance Gstreamer DM365
