Cobalt Digital’s Ciro Noronha to Present Paper: “A Study of Protocols for Low-Latency Video Transport Over the Internet” at 2018 NAB Show (April 12, 9:20 a.m.)


As part of the Broadcast Engineering and Information Technology Conference, Cobalt Digital Director of Technology Ciro Noronha will present a paper titled “A Study of Protocols for Low-Latency Video Transport Over the Internet.”

The session will be most useful for broadcasters that are considering the internet as a low-cost contribution link but are concerned with latency and reliability. The paper investigates Selective Retransmission (also known as ARQ) and SMPTE-2022 FEC, two common protocols for dealing with the issue of packet loss and the tradeoff between latency and reliability. Using an encoder/decoder pair, Noronha will present results of lab tests using a network simulator specifically designed to analyze the two protocols, as well as results from an internet link between locations in California and Illinois. Noronha will also offer guidelines for implementation.

The 20-minute presentation will take place in North Hall Meeting Room N256.
