AC4: The Next Generation ATSC 3.0 Audio Standard

Dolby Laboratories

Guest Speaker: Neal Roberts and Doug Ribordy

It’s hard to believe our existing digital TV standard is more than 20 years old. As of this year’s NAB show, the next generation television broadcast standard, ATSC 3.0, has become omnipresent and mainstream. Mid-2017 will likely see official completion of the ATSC 3.0 standard, with FCC approval to allow broadcasters to use the new system expected later this year. South Korea is starting official broadcasts this month in preparation for live UHD coverage of the 2018 winter Olympics.

The 3.0 standard is built on an IP backbone and offers much more robust modulation for use on tablets and mobile devices in motion at high speed. It can include 4k video resolution, increased visual dynamic range, higher frame rates and wider color gamut; a “magnitude greater” enhanced audio experience, built in audience measurement, improved accessibility, and enhanced emergency alerting. Development of 3.0 is becoming mature, with several standalone and SFN experimental transmitters and arrays around the country, including one here in Washington, DC operated by Sinclair.

This month Neal Roberts, Manager Broadcast Marketing and Licensing, and Doug Ribordy, Director of Technical Sales for Dolby Laboratories will delve into the AC4 broadcast audio standard of the Next Generation ATSC 3.0 system. Highlights include seamless end-to-end workflow from live, through post, to air and streaming. Immersive audio in 3D space, dialog enhancement, intelligent loudness, descriptive services, personalized streams, and more efficient compression are further features.

Perry Priestly, CEO of Anywave Transmission, will start the program with a short timeline and overview of the ATSC 3.0 system.* He will also bring a commercial working exciter and analysis software to show how far along ATSC 3.0 has progressed—literally ready for prime time.

In addition to the in-depth talk, there will be hands-on encode / decode hardware demonstrations.

This month’s meeting is a joint collaboration of SBE Chapter 37, Washington DC Audio Engineering Society, and Washington DC Section of SMPTE. We will keep business for each of SBE / SMPTE / AES organizations brief to accommodate the program in reasonable fashion.

This timely and exciting presentation is of interest to a wide range of production, IT, broadcast, and content creation professionals. Attendees need not be members of respective engineering organizations. We invite any interested folks and guests, and look forward to the cross-promotion of our local engineering chapters.

Neal Roberts offers fifteen years of professional product/project management and integration experience in commercial and residential environments. He holds a U.S. patent, is a member of CEDIA, and worked on the Olympic games at Rio, Sochi, and London. Doug Ribordy has enjoyed 28 years of engineering/technical experience with companies including Dolby, DirecTV, Cisco Systems, General Instruments, and Compression Labs. 

(* This will be a preview for a forthcoming Baltimore SBE Chapter 46 meeting that will discuss testing and measurement of ATSC 3.0 transmission.)

Sandwiches, kindly provided by our friends at Dolby Laboratories, will be served at 6:00 PM. (Note: This is a bit sooner than our regular time!) We'll briefly discuss SBE / SMPTE / AES business about 6:15 PM and begin our presentation about 7:00 PM. Please RSVP by June 13th by dropping an e-mail to meet@sbe37.org and let us know if we should expect you for dinner!
