Item Notes
Protocol UDP, RTP or SRT.
Note : When using SRT, the SRT settings will need to be configured, see
Section 6.4.3 .

The multicast address range is 224.0.0.0 to 239.255.255.255. For more
guidance on multicast addressing, see Table 6-1 .
Port Port numbers are used to identify IP address connections.
