Synchronized Multi-Stream Transport Using RIST

By Ciro A. Noronha, Ph.D.

Many broadcast contribution applications require synchronized content decoding. In such applications, there are several video sources (typically cameras), whose content needs to be transported using encoders to an equivalent number of remote decoders. At the decoders, the playback needs to be synchronized – frames that arrive together in the encoders are required to come out together in the decoders. Typical applications are sports and worship, where multiple...

Bit-Rate Evaluation of Compressed HDR Using SL-HDR1

By Ciro Noronha, Kyle Wilken, and Ryan Wallenberg

In this white paper, we attempt to answer the question of whether or not there is a bit rate penalty when one uses SL-HDR1 to transport HDR over a compressed video link. We do that by establishing a baseline with native HDR video, and then switch to SL-HDR1 and determine at what bit rate the quality is the same as the native HDR.

Affordable HDR Conversion with SL-HDR1 Metadata

By Ciro A. Noronha, Ph.D.

High Dynamic Range (HDR) is an emerging technology that delivers noticeably better image quality than standard dynamic range (SDR) content with minimal bandwidth increase. However, while HDR continues to gain popularity, SDR needs to be preserved – at least for the near future...

An Overview of Compressed Video Transport Protocols over IP

“The nice thing about standards is that you have so many to choose from.”
Andrew Tanenbaum, Computer Networks, 2nded., p 254

•There are many protocol options in use today for transporting compressed video over an IP network
•We will present an overview of these options, and discuss where they are best applied

A Performance Measurement Study of the Reliable Internet Stream Transport Protocol

The speed and reliability of the Internet has made it possible for broadcasters to use it as a cost-effective low-latency contribution link. Many companies have commercial products providing this functionality, and all of these products are implemented as a variation of the ARQ (Automatic Repeat reQuest) protocol. The Video Services Forum (VSF) has published the TR-06-1 Reliable Internet Stream Transport protocol specification to provide interoperability between such products. The first...

White Paper — A Study of Protocols for Low-Latency Video Transport over the Internet

This scholarly paper investigates and presents, in full detail and analysis, a comparison between SMPTE-2022 FEC (Forward Error Correction) and new Selective Retransmission techniques such as ARQ (Automatic Repeat reQuest) . The analysis here demonstrates the superiority of ARQ vs SMPTE-2022 in terms of packet recovery capabilities while achieving this with much lower overhead and latency.

The paper is co-written by Dr. Ciro Noronha, Ph. D. of Cobalt Digital. The paper is to be...
