Video: 2019 Display Trends and Hot Display Apps

Display technology has always been deeply intertwined with broadcasting. After all, when John Logie Baird first demonstrated his working television, he had to invent both the camera and the display device, then known as at the televisor. He himself worked tirelessly on improving television and less than 20 years after his black and white debut was working on a colour television which used two CRT (Cathode Ray Tubes) to produce its picture culminating in the world’s first demonstration of a colour TV in 1944 – incidentally discovering, demonstrating and patenting 3D TV on the way!

So it is today that the displays define what we can show to viewers. Is there any point in mastering a video to show at 10,000 NITs if there is no display that can show something so bright? Pushing all of Europe and the US’s television programmes to 8K resolution is of limited benefit when 8K TVs are in limited supply and in few homes.

This talk looks at the state of the art of display technology seeing where it’s being used and how. Digital Signage is covered and of course this is where the high brightness technology is developed, for signs outside, some of which could influence more conventional TVs on which we want to watch HDR (High Dynamic Range) video.

When OLED technology first came along it was quickly slated as a great option TVs and yet all these years later we see that its adoption in large panels is low. This shows the difficulty, sometimes, in dealing with the technical challenges of great technologies. We now see OLEDs in wearable devices and smaller screens. The number of the screens is quickly increasing as IoT devices, watches and other electronics start to adopt full screens instead of just flashing LEDs. This increase in manufacturing should lead to renewed investment in this field potentially allowing OLEDs to be incorporated in to full-sized, large TVs.

The talk finished with a look at the TV market covering quantum dots and what people really mean when they mention ‘LED TVs’.

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


With the SMPTE 2110 suite of standards largely published and the related AMWA IS-04 and -05 specifications stable, people’s minds are turning to how to implement all these standards bringing them together into a complete working system.

The JT-NM TR-1001-1 is a technical recommendation document which describes a way of documenting how the system will work – for instance how do new devices on the network start up? How do they know what PTP domain is in use on the network?

John Mailhot starts by giving an overview of the standards and documents available, showing which ones are published and which are still in progress. He then looks at each of them in turn to summarise its use on the network and how it fits in to the system as a whole.

Once the groundwork is laid, we see how the JT-NM working group have looked at 5 major behaviours and what they have recommended for making them work in a scalable way. These cover things like DNS discovery, automated multicast address allocation and other considerations.

Video: Blockchain & the Hollywood Supply Chain

At The Broadcast Knowledge, we’re continuing to cut through the hype and get to the bottom of blockchain. Now part of the NAB drinking game along with words like AI and 5G, it’s similarly not going away. The principle of blockchain is useful – just not useful everywhere.

So what can broadcasters do with Blockchain, and – given this is a SMPTE talk – what can film studios do with it? It’s doubtless that blockchain really makes secure, trusted systems possible so the mind immediately jumps to using it to ensure all the files needed to create films are distributed securely and with an audit trail.

Here, Steve Wong looks at this but explores the new possibilities this creates. He starts with the basics on what blockchain is and how it works, but soon moves in to how this could work for Hollywood explaining what could exist and what already does.

Video: Content Production Technology on Hybrid Log-Gamma


‘Better Pixels’ is the continuing refrain from the large number of people who are dissatisfied with simply increasing resolution to 4K or even 8K. Why can’t we have a higher frame-rate instead? Why not give us a wider colour gamut (WCG)? And why not give us a higher dynamic range (HDR)? Often, they would prefer any of these 3 options over higher resolution.

Watch this video explain more, now.

Dynamic Range is the word given to describe how much of a difference there is between the smallest possible signal and the strongest possible signal. In audio, what’s the quietest things that can be heard verses the loudest thing that can be heard (without distortion). In video, what’s the difference between black and white – after all, can your TV fully simulate the brightness and power of our sun? No, what about your car’s headlights? Probably not. Can your TV go as bright as your phone flashlight – well, now that’s realistic.

So let’s say your TV can go from a very dark black to being as bright as a medium-power flashlight, what about the video that you send your TV? When there’s a white frame, do you want your TV blasting as bright as it can? HDR allows producers to control the brightness of your display device so that something that is genuinely very bright, like star, a bright light, an explosion can be represented very brightly, whereas something which is simply white, can have the right colour, but also be medium brightness. With video which is Standard Dynamic Range (SDR), there isn’t this level of control.

For films, HDR is extremely useful, but for sports too – who’s not seen a football game where the sun leaves half the pitch in shadow and half in bright sunlight? With SDR, there’s no choice but to have one half either very dark or very bright (mostly white) so you can’t actually see the game there. HDR enabled the production crew to let HDR TVs show detail in both areas of the pitch.

HLG, which stands for Hybrid Log-Gamma is the name of a way of delivering HDR video. It’s been pioneered, famously, by Japan’s NHK with the UK’s BBC and has been standardised as ARIB STV-B67. In this talk, NHK’s Yuji Nagata helps us navigate working with multiple formats; HDR HLG -> SDR, plus converting from HLG to Dolby’s HDR format called PQ.

The reality of broadcasting is that anyone who is producing a programme in HDR will have to create an SDR version at some point. The question is how to do that and when. For live, some broadcasters may need to fully automate this. In this talk, we look at a semi-automated way of doing this.

HDR is usually delivered in a Wide Colour Gamut signal such as the ITU’s BT.2020. Converting between this colour space and the more common BT.709 colour space which is part of the HD video standards, is also needed on top of the dynamic range conversion. So listen to Yugi Nagata’s talk to find out NHK’s approach to this.

NHK has pushed very hard for many years to make 8K broadcasts feasible and has in recent times focussed on tooling up in time for the the 2020 Olympics. This talk was given at the SMPTE 2017 technical conference, but is all the more relevant now as NHK up the number of 8K broadcasts approaching the opening ceremony. This work on HDR and WCG is part of making sure that the 8K format really delivers an impressive and immersive experience for those that are lucky enough to experience it. This work on the video goes hand in hand with their tireless work with audio which can deliver 22.2 multichannel surround.

Video: Beyond SMPTE Time Code – the TLX Project

SMPTE Time Code started off in the 1970s and has evolved yet in some ways remained unchanged. It is key to electronic video editing, and has found application in many other fields and industries including live events. This is Armin Van Buren explaining how he uses SMPTE timecode in his live DJ sets.

The more we push technology, the more we demand form timecode, so now there is the TLX project (Time Label, eXtensible) which seeks to define a new labelling system.

The webinar will provide an overview of the emerging design, and is intended to provide a preview for potential users, and to encourage participation by those with expertise to offer.

Peter Symes, the host, covers:

  • The history of timing
  • What SMPTE ST 12 is and its evolution
  • The concept of TLX
  • Use of PTP & provision for extensibility
  • What types of data can TLX convey
  • Q&A!

Watch now to hone your knowledge of the SMPTE timecode that already exists and to get ready to understand TLX.

Webinar: Women in Technology: Now and in the Future

Date: Wednesday 27th February 2019
12:30 PM EST / 9:30 AM PST / 17:30 GMT

Ofcom recently surveyed the 5 main UK broadcasters and found that women held only 25% of technical roles and so the report shines more light on a problem we all live with in this and many other industries. Pleasingly there are noticeable and increasing steps of late to actively counter the gender imbalance when it comes to workplace diversity.

More can always be done, but recent, successful, steps by IBC to even out male/female representation in the conference speakers is one example of taking concrete steps to ensure that the women who are in the industry are heard and seen. Fortunately IBC is not alone in this and many trade shows across industries have taken positive steps and, at the very least, included Women in Technology sessions in their agenda.

This webcast brought to you by SMPTE and SID, the Society for Information Display, looks at:
• Why Women in Technology activities are becoming more important in the high tech industry;
• How the display industry does in terms of diversity;
• What is next for the industry and how can women contribute to its success.

Video: Enhanced Redundancy of ST 2059-2 Time Transfer over ST 2022-7 Redundant Networks

We’re all starting to get the hang of the basics: that PTP is the new Black and Burst, that we still need sync to make studios work and that PTP (IEEE1588) is standardised under ST 2059 for use in the broadcast industry. So given its importance, how can we make it redundant?

Thomas Kernen from Mellanox and Chair within the STMPE standards community takes about his real-lift work on implementing PTP with an eye on redundancy methods

Thomas covers the following and more:

  • Whether 2022-7 works for PTP
  • BMCA Redundancy Model
  • Multiple Grand master use
  • Adjusting to dynamic variations in timing feeds
  • IEEE 1588 v2.1
  • Timing Differences in basic networks

On-Demand Webinar: Human Perception Fundamentals – Colour, Contrast & Motion


Thursday February 7th, 10am PST / 1pm EST / 18:00 GMT
Now available on-demand!

There is so much talk about HDR, wide colour gamut (WCG), ‘Better Pixels’ and all the TVs seem to interpolate motion up to 100Hz or above, that it’s good to stop and check we know why all of this matters – and crucially when it doesn’t.

SMPTE’s new ‘Essential Technology Concepts Webcasts’ are here to help and for the first webcast, David Long will look at the fundamentals of colour, contrast and motion in terms of what we actually see.

This promises to be a great talk and, the chances are, even people who ‘know it already’ will be reminded of a thing or two!

Video: Where are the Women? The importance of visibility in achieving inclusivity

 

“If she can see it, she can be it,” is the catch phrase of the Geena Davis Institute on Gender in Media. The issue being if she’s not seeing it, it’s almost impossible to convince a young woman that a career in STEM is even fathomable.

For us in the broadcast industry, it’s clear there is a lot to do and this is work that needs to be done at all ages.
Please, take it upon yourself do to something this year, however small, to address the gender imbalance in broadcast.

A recent study related to me by a science teach fresh back from a conference found that if girls hadn’t become interested in science by the age of 6, then when they come to choose their exam choices at 14 and beyond, they were vastly less likely to choose STEM topics. However, many are interested yet put off by all sorts of factors later on – many of which can be addressed.

When women feature in film and TV, this directly influences real people. The Hunger Games’s Katniss Everdeen was “the major cause of waiting lists for archery lessons from coast to coast.” a few years ago. In 2018 a study was released on ‘The Scully Effect’, about the real world effect of Dana Scully from The X-Files:
Of the women surveyed, “63% say Scully increased their confidence that they could excel in a male-dominated profession.”

In this talk at the SMPTE ATC, Krystle Penhall, takes us through these studies, examines the problems in STEM today and how IBM and the aerospace industry have tried to counteract the problems they face.
