Video: AMWA NMOS State of Play

Posted on 1st March 2019 by Russell Trafford-Jones

With all the talk of the SMPTE ST 2110 standards suite, it’s sometimes forgotten that it only deals with content. If you want a working system, you’ll need to do a few more things – find new devices on the network, work out what they can do, control them, guarantee the bandwidth and often deal with metadata that arrives separately like tallies.

This is what the AMWA NMOS specifications do. Peter Brightwell and Thomas Edwards have been heavily involved in creating them and in this video lead us through what each one does and how they are used.

Video: Designing and Utilising SMPTE 2110 for Broadcast: Opportunities and Challenges

Posted on 14th February 2019 by Russell Trafford-Jones

A meeting of experienced minds here at the Pittsburgh SMPTE section talking about the opportunities and challenges of ST-2110. Phil Myers from Lawo talks optimistically about the challenges that can and often have been solved in implementing 2110 whether that be network infrastructure or timing, giving a good primer on the whole topic as he starts the session.

Hugo Gaggioni from Sony, talks about NMOS, explaining what AMWA does and the difference between their IS-04,05 and 06 specifications.

Karl Kuhn from Tektronix then discusses packet pacing, PTP and network architectures. He then looks at how to monitor PTP and see it is working well.

With the panel session at the end, joined by Dan Turk from NEP, there is a free-ranging discussion covering some of the following topics:

Control of IP networks
The limits of IP
Multicast traffic
Network Architecture
True non-blocking switches
Break-even points of IP systems
Split essences & dropping blanking
Network planning for UHD
Handling loss of network on PTP implementations
plus much more!

Video: AMWA NMOS IS-04 and IS-05 Scalability and Performance

Posted on 8th January 2019 by Russell Trafford-Jones

AMWA’s discovery and registration protocols IS-04 and IS-05 play a big role in making IP systems usable, allowing the system to easily identify new kit when it’s plugged in and understand its capabilities. However, deploying such systems at scale should give anyone pause for thought – how scalable are they? How does the system recover after a network outage? Clearly we wouldn’t want the system to be brought down by the administrative burden.

Rob Porter, from Sony Europe Ltd., has done the research and presents it here at the VSF’s IP Showcase at the 2018 IBC.

Rob gives a brief overview of the two specifications, describing their APIs and the open source nature of them. He then goes on to explain how he emulated this large number of devices and what he found.

Finally, Rob wraps up the session by explaining how he optimised network-loss recovery times and summarises best practices.
