[0070] According to the first embodiment of the present invention, corresponding to the method for the video monitoring system to push content to IPTV in the first case, the "global eye" video monitoring system can access the video resources of IPTV, that is, the video monitoring point is used as the IPTV system The whole process is: physical unit 106 (physics Unit, PU, ​​commonly referred to as front-end unit) → video transfer and distribution unit 102 (Video Transfer and Dispatch Unit, VTDU) → digital matrix 104 → MR 301 → content distribution network 302 (Content Delivery Network, CDN)→STP 303. Among them, the analog video interaction is realized between the video surveillance system and the IPTV system through a digital matrix and a dedicated STP, that is, the first interface device takes the digital matrix 104 as an example, and the second interface device takes the STP 303 as an example. The method is as follows: figure 2 shown, including the following steps:

Abstract

The invention provides a device for realizing intercommunication of a video monitoring system and a video service system, which comprises the video monitoring system, a first interface device, the video service system, a second interface device and a third interface device, wherein the video monitoring system is used for sending digital video to the first interface device and receiving digital video sent by the third interface device; the first interface device is used for receiving the digital video sent by the video monitoring system, restoring the digital video into analog video and transmitting the analog video to the video service system; the video service system is used for receiving the analog video sent by the first interface device and sending the digital video to the second interface device; the second interface device is used for receiving the digital video sent by the video service system, restoring the digital video into analog video and transmitting the analog video to the third interface device; and the third interface device is used for receiving the analog video sent by the second interface device, decoding the analog video into digital video and sending the digital video to the video monitoring system. The device can realize the intercommunication of the video monitoring system and the video service system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for realizing intercommunication between a video surveillance system and a video service system. Background technique [0002] The development of video technology is similar to the development of other communication technologies. It has experienced the trajectory from analog to digital and then to network. The development of optical technology and analog electrical signal technology has led to the birth of video technology. Video technology initially carried video signals in continuous analog signals. Due to the limitations of analog technology, broadcast distance and transmitted video content, analog video technology , have great limitations. With the development of digital technology, digital video technology has also developed greatly, which can transmit rich and colorful video content across long distances. Today, with the rapid development of n...
