ANALOG AND DIGITAL VIDEO MONITORING FUSION SYSTEM AND FUSION METHOD THEREOF

摘要

The present invention discloses an analog and digital video surveillance combination system and method. The system comprises an analog video surveillance system, a digital video surveillance system and a digital-analog virtual matrix, wherein the digital-analog virtual matrix, connected between the analog video surveillance system and the digital video surveillance system, is configured to realize a conversion of signaling protocols between the analog video surveillance system and the digital video surveillance system; acquire a video signal from the analog video surveillance system, convert the video signal into a digital video stream and send the digital video stream to the digital video surveillance system; acquire a digital video stream from the digital video surveillance system, decode the digital video stream and output a decoding result to the analog video surveillance system. The present invention realizes that the digital video surveillance system can access and control a video source of the analog video surveillance system, and meanwhile, the analog video surveillance system can also control and access a video source of the digital video surveillance system, so that two types of video surveillance systems together existing in the related art can be in seamless butt joint; and resource sharing can be realized, thereby avoiding resource waste caused by updating technology and reducing the updating cost of the system.
