1.RTSP multicast allows AVC-2K to push streams in a multicast manner. Compare with unicast, the difference is that when there are multiple clients that need to receive streaming media, unicast mode needs to process and push multiple video streams. But multicast mode can copy and push a video stream to multiple clients, which improves the performance of the AVC-2K push video stream and greatly reduces the network bandwidth occupancy.
2.How to configure: Enter the AVC-2K web control interface, check RTSP in Misc Steam, and select “Multicast” as Enabled, then enter the Multicast IP address (range 188.8.131.52 ~ 184.108.40.206) or use the default value (220.127.116.11), fill in the Multicast Port (range 2000-65531) or use the default value (8540), and click "Apply" after filling in,shown as in Figure 1.
4.1 In the latest firmware AVC2K-V18.104.22.168,the maximum video bit rate has been increased to 16M.
4.2 When you use RTSP protocol but do not enable Multicast for streaming, you could push 8 video streams to up to 8 clients, but the total bit rate does not exceed 16M. For example, you can push a 16M video stream to one client, or eight 2M video streams to 8 clients.
4.3 When you use RTSP Multicast mode to push stream, you can push video streams to up to 200 clients, each video stream supports a maximum of 16M bit rate, the total bit rate is unlimited
The above is an introduction on how to use the RTSP Multicast. The RTSP Multicast has better performance. We recommend that you use this mode.
