Problems solved by technology

However, on the one hand, it is impossible to realize the transmission of data streams across regions. On the other hand, if there are multiple third-party media servers requesting the data stream, it will cause network congestion in the data stream transmission of the camera.

Abstract

The invention relates to the technical field of media transmission, and provides a cascade media transmission link management method and device, and the method comprises the steps that a downlink platform receives request information which is transmitted by a third-party uplink platform and is used for requesting a data stream of a camera, and transmits the request information to the uplink platform; if the uplink platform determines that the request information is the first request of the data stream of the camera, a session module is created, and the session module provides a request cache list; after determining that the session invitation of the camera is successful, the uplink platform sends a data stream forwarding request to the media server based on each piece of request information in the request cache list, and sends a stream pushing message to the target camera; and the media server allocates corresponding ports to the request information according to the data stream forwarding request, determines corresponding third-party media servers, and distributes the data streams to the corresponding third-party media servers through the ports. Therefore, cross-regional transmission of the data stream of the camera is realized, and the problem of network congestion in data stream transmission of the camera is 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 cascaded media transmission link management method and device. Background technique [0002] The security monitoring industry generally applies GB / T28181. For example, the equipment in the existing security monitoring system uses the Session initiation Protocol (SIP) in GB / T28181 to communicate, so that when a third-party media server requests security monitoring When the data stream of the camera in the system, the camera can transmit the data stream to the third-party server. However, on the one hand, the transmission of data streams across regions cannot be realized; on the other hand, if there are multiple third-party media servers requesting the data streams, network congestion will occur in the data stream transmission of the camera. Contents of the invention [0003] The embodiment of the present application provides a casca...
