AC4: The Next Generation ATSC3.0 Audio Standard

Perry Priestly, CEO, Anywave Transmission
Special thanks to Fred Willard of Univision for conceiving of, and doing the bulk of arrangements for, this meeting!
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's presentations 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 ATSC3.0 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 section 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.
(* This will be a preview for an upcoming Baltimore SBE Chapter 46 meeting that will discuss testing and measurement of ATSC 3.0 transmission. Perry will bring a commercial working exciter and analysis software to the June 15 meeting at WETA to show how far along ATSC 3.0 has progressed—literally ready for prime time.)
