A one-to-many access networking code stream distribution method and system

Abstract

The invention discloses a one-to-many access network code flow distribution method and system. The front-end equipment receives the stream request message from the first back-end platform, and when its own capability reaches the upper limit, it transmits data streams from other back-ends in the network with the front-end equipment. Select a back-end platform with remaining capacity in the platform as the second back-end platform; then the front-end device carries the information of the second back-end platform to respond to the flow request message of the first back-end platform; the first back-end platform sends the second back-end platform The end platform sends a stream request message, and receives the code stream from the second back-end platform. The present invention forwards media streams through other back-end platforms that have established media stream connections with front-end devices, without configuring a media stream forwarding server, and each back-end platform does not need additional configuration in the process of requesting streams, and still requests streams to the destination. Based on the forwarding of the back-end platform, it can ensure that all devices in the network can request the corresponding real-time code stream, avoiding the occurrence of no code stream, so as to ensure the normal operation of the overall business and reduce risks.

Description

technical field [0001] The invention belongs to the technical field of video surveillance code stream distribution, and in particular relates to a one-to-many access networking code stream distribution method and system. Background technique [0002] Video surveillance is an important part of the security system. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. In recent years, with the rapid development of computer, network, image processing and transmission technology, the popularization trend of video surveillance has become more and more obvious. [0003] Based on the development of the current protocol (such as the ONVIF protocol), the one-to-many networking method is becoming more and more common. The more common way is that the front-end equipment such as the network camera IPC is connected to multiple back-end platforms at the same time. This networking method can explore IPC functions a...

Problems solved by technology

However, the root cause of this problem is that the capabilities of the front-end equipment itself have reached the upper limit. If there is no business change, re-requesting streams or going online and offline still cannot solve the problem of no streams

For forwarding through the media stream forwarding server, an additional media stream forwarding server needs to be configured, and all code streams will pass through the media stream forwarding server. For the entire system, the media stream forwarding server will become a performance bottleneck and not efficient enough
