Problems solved by technology

Therefore, in the process of video transmission, it is necessary to wait for the decoder to complete the identification of the idle decoding channel, and then wait for the encoder to complete the video data transmission. The identification work occupies the decoding channel resources of the decoder, and the data transmission work occupies the encoder. Encoding channel resources, which leads to greatly reduced video transmission efficiency

Abstract

The embodiment of the invention discloses a physical isolation method of a video monitoring system and the video monitoring system. The method comprises the following steps: receiving a video-on-demand request of a video source sent by an intranet client through an intranet server, and sending a video-on-demand instruction comprising an identifier of the video source to an extranet gateway; determining an idle decoding channel in a target decoder through an external network gateway, pulling the video source to the idle decoding channel for video decoding, and sending a video source decoding result to an idle encoding channel in a target encoder through the target decoder for video encoding; and determining an idle coding channel corresponding to the idle decoding channel through the intranet server, and providing the identification information of the idle coding channel to the intranet client. According to the technical scheme provided by the embodiment of the invention, channel resources occupied by identifying idle decoding channels for a decoder and transmitting data to intranet equipment for an encoder are released, so that the video transmission efficiency of a physically isolated video monitoring system is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of network video surveillance security, and in particular, to a physical isolation method of a video surveillance system and a video surveillance system. Background technique [0002] Network cameras have great advantages in many aspects such as network construction, construction deployment, clarity, and intelligent analysis applications. At the same time, with the continuous increase of network bandwidth and the reduction of network construction costs, the application of network cameras has become popular rapidly. The application of network cameras and the sharing of camera data between different networks pose a threat to network security. How to share and use network cameras between different networks while ensuring the security isolation between each network is very important. [0003] In the isolation method of the prior art, when the external network device sends video to the inter...
