Besides RTMP, RTSP, HLS, or MPEG-TS ingests for livestreaming, Castr has recently added SRT streaming protocol to its supported technologies. Castr is proudly being one of the very first platforms that support streaming with SRT, improving its broadcast capabilities and offering even better delivery efficiency than before. 

What is SRT?

SRT, short for Secure Reliable Transport, is developed originally by Haivision. The protocol is relatively new in the market, with many promising advantages for livestreaming demands. SRT shows excellent efficiency in optimizing video streaming performance and delivering it across unstable networks. 

SRT is an open-source protocol with many similarities to FTL and WebRTC in offering sub-second latency for live broadcasting videos. With dreamlike benefits of delivering streams over suboptimal networks and near real-time streaming speed, SRT is considered the substitute to RTMP in the near future. 

How is SRT Compared with RTMP?

An SRT stream is 12 times faster than an RTMP one, with stable delivery over suboptimal networks. As RTMP has been released and matured much longer than SRT, its development has pretty much come to a stop, while SRT is still developing drastically over the years.

Here’s a quick comparison of the two streaming protocols:

How to Start Streaming with SRT from Castr?

Currently, Castr is offering SRT support in the beta version for both livestreaming and multistreaming plans. SRT application will be adopted across all Castr’s products in future updates. 

SRT is supported as an ingest for your stream source to Castr. From that, Castr will deliver your stream to your website and other social media platforms. Note that the majority of streaming platforms have no support for SRT yet. However, rest assured that your stream from Castr will reach the destination in RTMP protocol using a more reliable and stable connection.
