Presenting RIST at NAB

The RIST Forum recently took part in the IP Showcase at NAB.  RIST members and Directors were part of multiple discussions demonstrating the interoperable standard for transporting live video across unmanaged networks and various real-life use cases for RIST.

To gain insight into the IP Showcase and learn more about RIST, have a look at some of the presentations from the event.

Introduction to RIST Advance profile: 

The Video Services Forum recently published TR-06-3, RIST Advanced Profile.

This new Specification includes features such as a tunnelling mode for legacy protocols, as well as new additional security features.

In this presentation, our President, Ciro Noronha of Cobalt Digital, gives an overview of RIST Advanced Profile.

New RIST source adaptation: 

The RIST AG is currently working on a new and exciting feature: source adaption that will be a part of the RIST TR-06-04 specification. Source adaptation is a set of messages between the receiver and sender to provide valuable information with emphasis on link (or multi-link) metrics.

In this presentation, Adi Rozenberg of AlvaLinks highlights how these metrics can be used to adapt the use of the available links between sender and receiver (and even Sender to multitude of receivers) and adapt the stream over each link or the source itself (reduce bitrate in case of trouble or increase when conditions are favorable).

Getting your Feet Wet with LibRist: 

Content delivery from source to destination platform(s) via IP networks requires both speed and faithful reproduction of the packets sent.

RIST is a relatively recent, now nearing maturity, specification for error-corrected transport with an emphasis on interoperability.

In this presentation, Sergio Ammirata of SipRadius introduces libRIST, a popular FOSS implementation of RIST.

Integrating Broadcast-Grade IP and Satellite:

By exploring potential hybrid IP and satellite workflows, Cerberus is tackling the challenges of moving broadcast feeds around the world and keeping the costs to rights for content owners.

This presentation illustrates the limits and costs of current live feeds using satellite and how Cerberus is meeting the growing demand for live content.

Ground-Cloud Integration and GCCG: 

Cloud usage is at an all-time hight after the past two years; however, most live broadcast productions are still single Vendor Monolithic applications. Ground-Cloud-Cloud-Ground is recommending that the industry creates common practices to make ground and cloud and wants to see multivendor cloud production, uncompressed exchange between cloud instances and agreed GCCG mechanisms.

In this presentation, Kieran Kunhya from Open Broadcast Systems and John Mailhot from Imagine Communications, present their recommendations on how to integrate GCCG into live broadcasting to avoid issues such as latency.
