Webinar: Building Large SMPTE ST 2110 Systems Using JT-NM TR-1001-1

Posted on 10th January 2019 by Russell Trafford-Jones

When? 10th Jan 2019. 1:00 PM EST / 10:00 AM PST / 18:00 GMT

TR 1001-1 from the JT-NM (Joint Task Force on Networked Media) gives guidance on protocols, configuration and architectures to use when setting up large ST-2110 systems.

John Mailhot and Brad Gilmer, both well trusted industry figures who are in the thick of creating and testing ST-2110 and the surrounding specifications, will lead us through what it is, what it tells us and, ultimately, how we can best go about creating a large ST 2110 system.

[Video]: Video Compression 101

Posted on 9th January 2019 by Russell Trafford-Jones

Jigsaw24’s Chief Engineer, Phil Crawley, explains video codecs from the fundamentals up. Codecs touch every part of the broadcast chain and are a vital part of the industry as much as of day to day life. So it’s worth brushing up or learning the basics to help you to fully understand what’s happening with today’s codecs, whether that be HEVC, AV1, JPEG XS or trusty MPEG4.

Phil covers:

Compressed and Uncompressed video & codecs
DCT Principles
Intra/Inter-frame compression
Acquisition Vs Editing Vs. Transmission codecs
Measuring compression effects
Codecs Vs File Formats & wrappers
Compression concatenation
MPEG4, H.264(AVC) & H.265(HEVC)

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.
