Live Cloud Ingest Using Open Alternatives RIST & SRT

As cloud production becomes an integral part of broadcasters' live workflows, the corresponding cloud infrastructure becomes an integral part of the media transport network. Cloud infrastructure providers, often public in nature, are accessible either through the public Internet or through leased lines. Regardless if public or private, experience shows these connections are not up to the quality standards required for low latency live streaming media, making quality enhancing technologies, such as retransmission or ARQ, an imperative part of the network infrastructure to deliver on the requirements for broadcast quality transmission. Two solutions have emerged as front runners on the quest for being the next de-facto standard for broadcast retransmission - RIST (Reliable Internet Stream Transport), and SRT (Secure Reliable Transport). This report compares these two alternatives from a theoretical and performance perspective and compares them to a commercial reference alternative.
