Following is a rundown of the day's topics and presentations.

Morning

Imaging Update Tutorial - Changing Images for Changing Times
9:00 a.m. - 10:00 a.m.
Display technology has changed rapidly since being released from the constraints of the CRT that dominated TV displays from the birth of television, and IP networks are coming of age to ship the bits and bytes around in the middle, but what does this mean for the images we will capture for our new TV sets and displays? This tutorial will cover the front-end technology for television, colorimetry and what the larger color triangle of wide color gamut primaries implies for image capture. Next up is the high dynamic range, through Human vision and NITs, color volume in WCG, what scene-referenced vs display-referenced systems offer in feeding the "better pixels" of new displays. Along the way we'll touch on some features of real world UHD & 4K cameras and capturing immersive images for VR.

SBE Executive Director's Remarks
10:00 a.m. - 10:15 a.m.
Presenter: John Poray; Executive Director; Society of Broadcast Engineers

Sinclair's 3.0 Vision - The Future of Broadcasting
10:15 a.m. - 10:55 a.m.
Spectrum is in demand, and wireless carriers claim they need what we have. Reverse auction, forward auction, back and forth like an exciting ping-pong match. Channel of allocations. Repack. 39-months. Sound familiar? Well, forget it! Soon the only important question will be, "What are we doing when we restart broadcasting with nextgen?" This discussion will bring an understanding of how we will wield the new tools and assumptions that shape QoS realities for nextgen broadcasting, unlocking the unique resources we offer. We must turn our coverage contours into areas of services with SFN deployments, and understand the impact this will have on our business assumptions and new opportunities. What does the broadcast network of the future look like? Sinclair, ONE Media and others are turning from contemplation to consummation.
Presenter: Mark Aiken; Vice President, Advanced Technology; Sinclair Broadcast Group, Inc.

Tutorial: IP - Are we ready for it? - And it for us?
10:55 a.m. - 11:35 a.m.
Video over IP is crossing the threshold of dream into reality. Proof of this is can been seen at the 2017 NAB Interoperability Zone in the North Hall jointly sponsored by IABM and AIMS. We will explore the pieces, software and hardware as well as the architecture to take full advantage of video on IP. Entire facilities can now be built without or with a minimum of SDI to accommodate legacy equipment. In a world where once key pieces of infrastructure, even the sync-generator and the once separate control layer are virtualized and routers are software defined, one needs to know how to integrate video into the IP Environment, and plan for the clear future of a format agnostic facility regardless if SD, HD or UHD.
Presenter: Stan Moote; CTO; IABM

The Origins of Our Digital Universe
11:35 a.m. - 12:10 p.m.
This paper explores the history of digital technology, and the contributions of the great inventors that led to modern digital media. Audio compression started in 1938, with the VOCODER [sic], Homer Dudley's landmark speech encoder. Dudley invented electronic speech analysis and synthesis, and achieved ten times speech compression. The onset of World War II created an urgent need for speech encryption of strategic conferences via shortwave radio links. In just six months, the unbreakable top-secret speech scrambler SIGSALY, was designed at Bell Telephone Laboratories. Brilliant engineers including Claude Shannon, Henry Nyquist, and Homer Dudley, invented and implemented eleven fundamental breakthroughs, including PCM, flash A/D conversion and spread spectrum. VOCODER and SIGSALY block diagrams are discussed, with their links to modern codecs. Dudley and Shannon's work on SIGSALY, Hedy Lamarr's spread spectrum, and Turing's scrambler are detailed. A reconstruction of the first PCM codec using vintage tubes is described. The presentation includes unusual photos, vintage music, early VOCODER speech and very rare SIGSALY-decrypted speech.

Lunch Break
12:10 p.m. - 1:10 p.m.

Afternoon

12 GHz Cable
1:10 p.m. - 1:50 p.m.
When will copper fail us? From the beginnings of electronic media, broadcast engineers have struggled with the bandwidth limitations of interconnecting cable. When 4K and other high data rate services first appeared, it seemed only fiber could handle the bandwidth. But we thought the same when SDI was introduced. Belden first introduced 4794R and now 4855R. Will these be the new 8281 and 9209? Have we reached the limit of electrons in cable, or are there new technologies that will extend the convenience of cable and connectors into the next generation of broadcast? With each advance in interconnection, new methods for installation and use come with new limitations along with the improvements in bandwidth. This tutorial covers interconnection in the 12GHz world, and what is likely to be the technology for the next generation.
Presenter: Steve Lampen; Multimedia Technology Manager; Belden

Four Fundamental Frameworks for Professional Media Facilities –
Key Foundations for Interoperability
1:50 p.m. - 2:20 p.m.
The Joint Task Force on Networked Media (JT-NM), sponsored by the AMWA, EBU, SMPTE and VSF, has published a document called Reference Architecture v1.0 (RA) with the intention that this captures best practices, relevant standards, and key frameworks for the transition from SDI to IP. While the RA includes a lot of useful information, perhaps the most important concepts have to do with the four fundamental frameworks – identity, timing, discovery and registration and connection management. Attendees of this session will be introduced to the JT-NM Reference Architecture. They will learn about the four fundamental frameworks, and they will understand why these specific frameworks were identified as being critical to establishing interoperability in networked professional media facilities. They will learn about activities in the industry that are based on these frameworks, and they will be in a better position to interact with vendors and colleagues when discussing these topics.

Graceful Evolution Beyond HDTV
2:50 p.m. - 3:20 p.m.
For the past several years, the consumer electronics industry has been providing exciting new technology that goes beyond high definition. The evolution began with higher resolution (4K) and is now seeing the addition of high dynamic range (HDR), higher frame rates, and extended color space. The graceful evolution into enhanced HD content has the potential to bring forth an ecosystem that delivers a compelling and unambiguous value to the consumer. An important element in this evolution is making high value content widely available over the full range of delivery systems (broadcast, cable, OTT, etc.). There is a significant belief that 4K-HDR is the inevitable next step in content delivery; but is that the best next step for entertainment content? If we separate the two (4K and HDR) and proceed with high definition plus HDR, consumer acceptance for both 4K and HDR may in fact be accelerated.
Presenter: Geoffrey Tully; President; Geoffrey A. Tully Inc.

On the Verge: How Innovation Threatens the Future of Broadcast
3:20 p.m. - 3:55 p.m.
UHD, EDR, HDR, HFR, WCG, 8K… As the alphabet soup keeps getting thicker, it may be less clear which technological innovations will have the biggest impact on the future of broadcast. The dominance of on-demand viewing and the frequent advances in display technologies have shifted the balance of power from distributors to consumers. Traditional broadcast and cable companies are now in a race against OTT distributors such as Netflix and Amazon, who already have a clear lead on harnessing innovation to win more and more of viewers' time. Ultimately, the winning innovations are being chosen by a new generation of content creators, those redefining media to cross platforms freely and eschew the conventions of format and distribution that have defined our past.

The Evolution of Playout: Virtualization and the Cloud
3:55 p.m. - 4:25 p.m.
From hardware chains to products built on commodity technology, there has been a continuous evolution as broadcasters take advantage of new technology. Most recently, there has been an increasingly active discussion regarding the use of the cloud and virtualization technology for television playout. Will this be a significant development for television broadcasters? Under what circumstances does cloud and virtualization technology make sense for today broadcasters? There has been an increasingly active discussion regarding the use of the cloud and virtualization technology for television playout.
