The present invention provides a data stream transmission method and device, the method comprising: when the video management server determines that the access device needs to copy the data stream for the target client, the access device receives the copied data stream from the video management server Redirection policy; if the access device receives a data flow that matches the copy redirection policy, the access device sends the data flow according to the destination address of the data flow, and uses the copy redirection The policy copies the new data flow for the destination client, and sends the new data flow to the destination client. Through the technical solution of the present invention, the working pressure of the streaming media server can be reduced, the processing resources of the streaming media server can be saved, the network bandwidth can be saved, and the duplication and distribution of the data stream can be completed in time, and the data stream can be transmitted to the client in real time. Moreover, under the premise of ensuring network security, the transmission path of the data flow can be made more reasonable and the transmission path can be simplified as much as possible.
Description
technical field [0001] The present invention relates to the technical field of video surveillance, in particular to a data stream transmission method and device. Background technique [0002] Streaming media refers to a media form that transmits data streams (such as audio data, video data, and multimedia files, etc.) in a network in a streaming manner. Compared with the online broadcasting form of downloading and watching, the typical characteristics of streaming media are: users can watch while downloading, without having to wait for the entire file to be downloaded. Due to the superiority of streaming media technology, this streaming media technology is widely used in video on demand, video conferencing, distance education, telemedicine and online live broadcasting systems. Among them, the streaming media server is the core equipment of the streaming media application and the key platform for the operator to provide services to the users. The main function of the stream...
