Then there is SRT (Secure Reliable Transport) developed by Haivision and made open-source (non-proprietary)in April 2017, subsequently endorsed by over 50 companies spanning internet streaming (Wowza, Limelight, etc.) and broadcast contribution (Harmonic, Eurovision, etc.) markets and applications.
It is currently used in two distinct use cases: Streamers who want to solve the first-mile challenges associated with RTMP; and broadcasters requiring low latency contribution and who want to mitigate the costs of private fibre networks or satellite. “To satisfy these challenges, SRTis a very compelling alternative to costly proprietary solutions,” says Haivision CMO Peter Maag. “SRT far surpasses RTMP with regard to latency, security, and bandwidth utilization.
