Video: A Basic Guide For Real-Time IP Video

There are a lot of videos looking into the details of uncompressed video over IP, but not many for those still starting out – and let’s face it, there are a lot of people who are only just embarking on this journey. Here, Andy Jones takes us through the real basics do prove very useful as a building block for understanding today’s IP technologies.

Andy Jones is well known by many broadcast engineers in the UK having spent many many years working in The BBC’s Training and Development department and subsequently running training for the IABM. The news that he passed away on Saturday is very saddening and I’m posting this video in recognition of the immense amount he has contributed to the industry through his years of tireless work. You can see from this video from NAB 2018 his passion, energy and ability to make complicated things simple.

In this talk, Andy looks at the different layers that networks operate on, including the physical layer i.e. the cables. This is because the different ways in which traffic gets from A to B in networking are interdependent and need to be considered as such. He looks at an example network which shows all the different standards in use in an IP network and talks about their relevance.

Andy briefly looks at IP addresses and the protocol that makes them work. This underpins much of what happens on most networks before looking at the Real-time Transport Protocol (RTP) which is heavily used for sending audio and video streams.

After looking at how timing is done in IP (as opposed to black and burst) he has laid enough foundations to look at SMPTE ST 2110 – the suite of standards which show how different media (essences) are sent in networks delivering uncompressed streams. AES67 for the audio is also looked at before how to control the whole kit and caboodle.

A great primer for those starting out, watch now!

Video: AMWA NMOS State of Play

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

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

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.

Video: ST 2110 over WAN

Andy Rayner from Nevion looks at using SMPTE ST 2110 on a Wide Area Network (WAN).

While using ST 2110 is a much discussed topic in the studio or within a building, there are extra difficulties in putting it between buildings, cities and countries with some saying it shouldn’t even be done. Here, Andy examines how you can do it whilst acknowledging the industry still has some decisions to make.

Topics discussed include:

  • SMPTE ST 2022-7 – dual flows
  • FEC use on ST 2110
  • Flow Trunking
  • Conversions to and from 2110 and 2022-6
  • Light/Mezzanine Compression
  • PTP Trunking and GPS-locked PTP
  • Multiple Timing Domains
  • Discovery & Control between buildings

Video: Uncompressed IP Video Basics

Top training here from Ed Calverly on the basics needed to understand uncompressed video. Presented at the IBC 2018 IP Showcase courtesy of the VSF.

Ed delves just far enough into the detail to tease out the important points of video over IP:

  • The need for timing
  • The legacy of blanking
  • Carrying data (VANC, HANC, Embedded audio etc.)
  • Benefits of splitting essences
  • TCP Vs UDP
  • Subnets and Routing
  • Multicast (i.e. IGMPv2 & v3)
  • PTP & SMPTE 2059
  • 2022-6, 2110, NMOS
  • Traffic Shaping: Narrow & Wide senders

Webinar: Control and Monitoring in an IP Infrastructure

Date: Monday 19th November 2018, 08:00 GMT and again at 16:00 GMT

Axon’s back with their 5th webinar in the Broadcast IP 101 series. Previously they have covered preparing for IP, the basics, Transport Formats and uncompressed vs compressed video. Now they are back to talk about control and monitoring.

The well-known 2022 and 2110 standards define transportation of video (and other essences). Like SDI-related standards, they don’t describe how to control the path of signals or monitor them. Unlike SDI, however, we expect to know what’s plugged in to our networks (AKA discovery) and then to control the data flow. There are proprietary and open specifications for doing this, including AMWA IS-04, IS-05 and IS-06 which deal with discovery, control and connection management.

In this webinar, CTO Peter Schut describes the lay of the land and how you can implement control and monitoring in an IP infrastructure.

The webinar happens twice. Once at 08:00 GMT (Midnight PT) and once at 16:00 GMT (11am ET).

Register now! Early, Late

Video: Full Stack 2110 with John Mailhot



John Mailhot from Imagine Communications discusses what ‘Full Stack’ means for video over IP. The SMPTE 2110 suite of standards is mainly about the transport of essences – but how to you simply plug in some equipment and get going? You need standards which discover and register the new device, you need timing to synchronise devices. It’s a whole ecosystem.

John walks us through the data flows (and workflows) necessary when you plug new 2110 kit in and we quickly discover there is more depth than we imagined.

John also discusses how DHCP can give you more than just IP addresses.

Covering IS-04, IS-05, PTP/SMPTE 2059, ST 2110 and IEE 802.1AB (LLDP). This is a very practical video. Why? Because understanding all this is key to diagnosis and troubleshooting.
