Reliable Internet Streaming Transport

RIST support in Nimble Streamer

What is RIST

Reliable Internet Streaming Transport (RIST) is a UDP-based transport technology with advanced streaming performance in un-reliable networks.

RIST all about the combination of interoperability and innovation. Developed jointly by a group of experts using a standards-based approach, RIST provides an open, interoperable and technically robust solution for low-latency live video over unmanaged networks. With RIST, interoperability is achieved through clear specifications, while vendors remain free to innovate within their own implementations.
