The Secure Reliable Transport (SRT) protocol is a new open source broadcast protocol, promoted by the SRT Alliance of which Clevercast is a member. It includes mechanisms for packet recovery while maintaining low latency between encoder and ingest server. It is therefore particularly suited for long-distance and high-quality broadcasting across unreliable and unpredictable networks like the public internet. Because of its reliability over long distances, we recommend it for broadcasts from outside of Europe.
Unlike RTMP, the SRT protocol has built-in mechanisms for authentication and encryption. SRT can also be used for single-language broadcasts, but the ability to add multiple (stereo) audio tracks to a single video broadcast makes it very suitable for multilingual live streaming.
Clevercast allows live streaming of tracks as separate languages. With a stereo track you can choose in Clevercast to stream the L+R channels as two separate languages, or to stream each language in stereo. The available number of languages depends on the SRT encoder you use (audio tracks supported by the encoder).
