<p>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.</p> |
