Hosted by the Video Services Forum (is an annual event that provides an opportunity for television professionals to explore the latest IP media technologies. The timely theme for this year’s event, “Innovations in IP for Media Production” will focus on innovative types of IP networking and video technologies and their application both for long-haul video transport and for the production studio. This year’s VidTrans will be totally virtual and use a highly interactive platform to engage attendees.

Building on his presentation at VidTrans 2020, Dr. Noronha will bring a fresh vision to HDR transport by leveraging quality metrics that better correlate with perceived quality and an industry standard method (BD-rate) for the comparison. This presentation will consider two options for transporting HDR over a communications link using compression, evaluating the required bit rates in both cases.

In addition to technical sessions, Cobalt, a leading member of The Reliable Internet Stream Transport (RIST) Forum, will join other manufacturers in conducting live demonstrations of the latest technologies for transporting video and audio over IP networks on behalf of RIST. Cobalt will demonstrate live transmission from an Android cell phone to a Cobalt Professional Decoder. The output of the decoder will go through an SDI monitor to illustrate how the original video of the cell phone is converted to a broadcast-grade SDI signal. Live real-time statistics will also be provided. The demo will be streamed live to YouTube using a Cobalt encoder.
