| Along with social progress and innovation in information technology, video surveillance,as a means of protecting public safety has been valued and welcomed by administration.Streaming media technology is gradually applied to video surveillance. Video surveillanceshowing a trend of diversification needs.Given the needs of public safety, local governments are trying to build the safe city. Asthe needs of management, managers would like some information about the camera open tothe public in a timely manner, such as the city’s traffic situation somewhere or someemergency information at someplace. However, most of the current video surveillancesystems use methods of local recording and real-time viewing by minority managers, whichunable to meet the needs of large-scale concurrent access. To solve this problem, this paperhas studied the hotspot information distribution technology in video surveillance. Incombination with results of laboratory studies in recent years, the P2P technology isintegrated into the monitoring information distribution. Real-time media stream conversionand hotspot information published automatically are key problems to be solved. Based on this,combined with video surveillance and research results, this paper designed a system ofreal-time conversion and media information automatically published, which makes it possiblethat hotspot information open to the public. During the study, we found that surveillancevideo media information differs from P2P distribution subsystem requirements. Surveillancevideo streams generate and transmit according with the new national standard, which can’t berecognized and played by ordinary video software. Therefore, we need to parse their videotransmission protocol to obtain video data, and then give it to the corresponding videodecompression module. In addition, when got the converted video stream, we need to publishit to P2P systems automatically. To achieve automatic publication, we must makecommunication and response interfaces with the original system, which complete the transferand dissemination of video stream together.In this paper, the surveillance video hotspot information distribution system does notchange the original system structure while allowing real-time monitoring of video streams open to the public and to meet the needs of large-scale concurrent access. Through the actualexperiment, the system can well meet the needs of current video surveillance application. |
