SRT: smooth, stable video streaming in all conditions

Poor network conditions can mean glitchy, stuttering video streams with distorted or frozen pictures. Secure Reliable Transport (SRT) technology addresses the challenges of remote video contribution while maintaining speedy delivery. SRT gives you the assurance of secure, stable, low-latency video streaming with remote cameras – even when Internet quality is less than perfect.

What is SRT?

We’ve never been more reliant on streaming video to help us keep us in touch. Everyone who uses the Internet for meetings with colleagues knows the frustration of jerky, interrupted or frozen video streams caused by poor network conditions.

Secure Reliable Transport (SRT) is an open-source protocol that combines encryption, packet loss recovery and jitter prevention technologies to preserve video stream quality and integrity. SRT harnesses latest developments in real-time IP communications, enhancing conventional network error recovery methods to deliver extremely stable, low-latency media streams.

Stream content securely

SRT also supports the powerful AES encryption standard. That means video content streamed over the public Internet using SRT is immune to unwelcome interception. It’s an extra level of reassurance that your enterprise videos and webinars really are secure at all times.

Examples of flexible workflow with SRT

Switch and mix SRT video content with compatible live streaming software, then upload to media server for distribution to viewers for consumption on different client devices.

Unique Adaptive Rate Control technology

Our latest 4K remote cameras also support Sony’s Adaptive Rate Control (ARC) technology*. If network bandwidth falls for any reason, our cameras compensate by reducing video stream bitrates until conditions improve.
