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

This application relates to the field of media transmission technology, and provides a cascaded media transmission link management method and device, including: the downlink platform receives the request information for requesting the data stream of the camera sent by the third-party uplink platform, and sends the request information to Go to the Shanglian platform; if the Shanglian platform determines that the request information is the first request of the camera's data stream, it will create a session module, which provides a request cache list; after the Shanglian platform determines that the session invitation of the camera is successful, based on the request cache list Each request information sends a data stream forwarding request to the media server, and sends a push message to the target camera; the media server allocates a corresponding port for each request information according to the data stream forwarding request, and determines the corresponding third-party media server. Distribute the data stream to the corresponding third-party media server. In this way, the cross-regional transmission of the data stream of the camera is realized, and the problem of network congestion in the transmission of the data stream 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...
