Secure reliable transport modes

Learn more about Listener, Rendezvous, and Caller modes in the SRT settings of Adobe Premiere Pro.

The SRT protocol involves a handshake between Premiere Pro and the viewing client. Once a valid handshake has been established, the video will be sent from Premiere Pro to the viewing client. A valid SRT connection can be made using three distinct modes:

Listener, Rendezvous, and Caller modes are highlighted in the Adobe SRT Settings dialog box.
Choose Listener, Rendezvous, or Caller mode in Adobe SRT Settings to set up your connection.

Mode

Function

Listener

In this mode, Premiere Pro waits for an active connection of the SRT stream to be sent from the viewing client. This is the default mode.

Caller

Premiere Pro initiates the connection of the SRT stream with the viewing client.

Rendezvous

Premiere Pro or the viewing client can initiate the connection of the SRT stream.

Connections between streaming modes

  • Listener and Caller mode: These modes work together when making SRT streaming connections. To make a connection with these modes, there must always be one caller and one listener. These modes work together as a connection pair.
    The caller will initiate the handshake with a listener and establish the SRT connection regardless of the direction of the video signal.

Premiere Pro can operate as either a caller or a listener, even though Premiere Pro can only stream video and audio out (Premiere cannot receive or ingest an SRT video stream). The mode is just for the establishment of the stream, not for the direction of the content stream. Video will always be sent from Premiere Pro to the viewer. Once the SRT connection is made, the modes are no longer relevant. 

Modes are selected depending on network configuration, viewer configuration, or other streaming configurations, such as connecting Premiere Pro to a dedicated SRT ingest server.

Caller or Listener modes configuration example: Multiple Premiere Pro workstations are being connected to a central SRT Routing server. A possibly efficient way to manage such a configuration is to place the Premiere Pro workstations into Listener mode and set the SRT server to Caller mode so adjustments can be made to the centralized SRT Server.

Conversely, if a set of Premiere Pro workstations isn't regularly set to connect to a central SRT server, the server could be set to Listener mode to receive any connection from a Premiere workstation without having the IP address for each central SRT server. These streams can be identified by the Stream ID parameter to the server.

  • Rendezvous mode: This peer-to-peer SRT handshake method is generally used for simpler, non-IT-managed networks. If Premiere Pro is in Rendezvous mode, the viewing client must also be in the same mode.

Typically, your IT administrator does not need to intervene to traverse a firewall in Rendezvous mode. The firewalls automatically route the UDP data to the correct endpoint. Both endpoints send handshake packets or data on the same port.
