Overview of Secure Reliable Transport

Learn how you can stream video and audio content to different viewers using SRT.

SRT, a video streaming protocol based on User Datagram Protocol (UDP), facilitates users to stream video and audio packets of information from Premiere Pro to different viewers. As the viewer receives the stream, acknowledgment information about its reliability is exchanged between Premiere Pro and the viewer.

The SRT stream always operates at the same video stream parameters as the Transit Output (Frame Size, Frame Rate, Sample Rate, Mix track Channelization, and more).

Reliable and Secure Streaming with SRT

• More secure: SRT has optional Advanced Encryption Standard (AES) Encryption, so the video and audio stream is secure. This makes SRT more secure than some other network streaming protocols.
• Less data loss: The data sent from Premiere Pro is broken into discrete packets of information and transmitted sequentially to the viewing client application. If there is any data loss (due to network congestion or poor network performance), the viewing client can request that the packet be sent again, maintaining the continuity of the stream.
• Better performance on slow networks: SRT is better able to send video data without interruptions on poor or slow networks. A certain amount of latency is always added to the SRT stream, allowing time for the two SRT endpoints to receive, acknowledge, and then resend packets of data lost over the network.

The end result of the packet verification system is less video and audio loss when transmitting over the network, at the expense of some level of latency between the sender and the receiver.
