Problems solved by technology

In the existing media transmission link management solution, if a service terminal wants to invite a camera’s video, two links need to be maintained, one is the session initiation protocol (Session initiation Protocol, SIP) uplink to initiate a session invitation to the camera The established SIP communication link, the other is the media link between the camera and the media server (used to send video to the media server), but the process of establishing the SIP communication link takes a long time, if there are other services in this process The terminal requests the video of the camera, which will cause network congestion in the data stream transmission of the camera

Abstract

The embodiment of the invention relates to the technical field of media transmission, and provides a media transmission link management method and device, and the method comprises the steps that a transcoding server receives request information which is transmitted by a service terminal and is used for requesting a data stream of a target camera; if the transcoding server determines that the request information is the first request of the data stream of the target camera, the transcoding server creates a target transcoding session module based on the target camera, the scheduling server creates a target scheduling session module based on the target camera, and the media server creates a media session module based on the target camera; wherein the target transcoding session module provides a request cache list; and a transmission channel between the target camera and the service terminal is established based on the target transcoding session module, the target scheduling session module and the media session module, so as to distribute the data stream to all the service terminals in the request cache list. According to the embodiment of the invention, the problem of network congestion in data stream transmission of the camera can be effectively avoided.

Description

technical field [0001] The embodiments of the present application relate to the technical field of media transmission, and in particular, to a method and device for managing a media transmission link. Background technique [0002] With the continuous acceleration of the networking process of the security industry, the advantages of Internet video relying on big data and artificial intelligence over traditional security monitoring are constantly showing. Therefore, how to integrate HD network cameras and network video recorders (Network Video Recorde, NVR) and other GB / T28181 output devices, and building a bridge between traditional security surveillance video and Internet video is an urgent problem to be solved. In the existing media transmission link management solution, if a service terminal wants to invite a camera’s video, two links need to be maintained, one is the session initiation protocol (Session initiation Protocol, SIP) uplink to initiate a session invitation to ...
