Pearl-2 User Guide
About streaming using SRT
Up to six of the video inputs configured for Pearl-2 can come from SRT sources (or one 4K SRT input) and
Pearl-2 can stream up to six SRT streams.
Before content is streamed between the SRT source and destination, a communication link must be
established between them for SRT control and recovery packets. Any firewalls blocking the path must be
traversed.
SRT streaming modes and firewalls
Streaming through firewalls can be a challenge. With SRT you get easy firewall traversal with little to no IT
involvement.
SRT offers three modes to simplify the process: Rendezvous, Caller, and Listener.
l
Rendezvous mode is the easiest to setup and usually doesn't need any intervention from your IT
administrator for the SRT stream from the source to traverse the firewall to the destination. The SRT
source and destination devices must use the same SRT port value, see
l
Caller and Listener modes work together to establish the SRT connection between your source and
destination devices when traversing the firewall is difficult. In this case, your IT network administrator
must configure the network to allow traffic that comes in on the port configured for SRT streaming and
forward the traffic to the destination device, see
