基于IPTV终端的视频监控系统的设计

Design of Video Surveillance System Based on IPTV Terminal

IPTV视频监控技术是未来三网融合最有特色的应用技术之一,同时家庭视频监控正成为监控行业的一个新领域。文中给出了一种基于IPTV终端的家庭视频监控系统的设计方案,该方案是基于C/S模式的构架,视频数据的压缩编码采用达芬奇技术实现,为了保证传输的质量,网络传输采用了RTP协议和基于丢包率的拥塞控制方法。最后,在2 Mb/s的ADSL宽带接入网络下进行测试,结果表明用户可以随时随地登陆到家庭视频监控系统中查看家庭情况。系统的时延控制在0.3 s之内。

IPTV video surveillance technology is one of the most distinctive of applied technologies in future triple play, while home video surveillance is becoming a new area of the monitor industry. In view of this, this paper presents a IPTV terminal-based home video surveillance system design and implementation process. The program is based on C / S model framework , uses the DaVinci technology to achieve the video data compression encoding, In order to ensure the quality of transmission, network transport module uses RTP protocol and packet loss rate-based congestion control method. Finally, the system is tested in the 2Mb / s for ADSL broadband access network, Test results show that users can login to the home video surveillance systems, and view the family situation at any time and any place. The system latency is controlled in 0.3 seconds.
