Successful case of different map transmission (remote video return) with millisecond delay
Recently, many customers have inquired about the transmission of different maps, and today I will bring you a successful case description of this solution. In this case, I used the ENCSHvideo transmission equipment. Now the live broadcast industry refers to the video broadcast as video transmission, and we will get used to the term in the future. , We just treat him as an Internet celebrity word, haha, it's actually video transmission. ENCSHThere are many kinds of protocols for video transmission: HTTP、RTSP、RTMP、SRT、NDIetc. Today we will be talking about the use SRTof remote video backhaul (referred to as different map transmission) as a transmission protocol. Please see the picture below:
First, we need to rent a public network server (Tencent or Alibaba Cloud), because SRTone end needs to have a public network IP, but now there are too few public network IPs, so we need to use the public network server to do it. Through, ensuring that the device has a public IP. For SRTspecific configuration, please refer to the following link: https://blog.csdn.net/weixin_41486034/article/details/106939264
Through the above picture, we have completed the mutual transfer of pictures from user A to user B, or user B to user A:
Camera A ----> ENCSH(A ground) -----> SRT@公网FRP (Low latency in milliseconds, the better the server performance, the lower the delay) -----> ENCSH(B ground) - ---> RTSP/NDI(RTSP second delay, NDI millisecond delay) -----> VMIXswitch
Camera B ----> ENCSH(B ground) -----> SRT@公网FRP (Low latency in milliseconds, the better the server performance, the lower the delay) -----> ENCSH(A ground) - ---> RTSP/NDI(RTSP second-level delay, NDI millisecond-level delay) -----> VMIX switch
And it can also be VMIXused for dialogue, but this solution is limited to point-to-point communication, if you want to have a meeting, it is recommended ZOOM. It ZOOMis currently supported NDI. Just replace the above picture VMIXwith ZOOM, if you use it ZOOM, you don't need to FRPpenetrate. ZOOMIts functions are video conference, web conference, web seminar, screen sharing. This requires you who are engaged in the live broadcast industry to dig.
Thank you, everyone, please leave a message to correct me if there is something wrong.
