Part 1
Introduction and Overview

What is Next Generation Audio (NGA) and why do we need it? Does ATSC 3.0 really need a new audio standard? Is this just a new way to do an old thing which will only succeed in adding complexity to our lives?

The promise of NGA is to make us more efficient at the thing we already do, while creating a framework which will permit new and exciting capabilities for content creation and distribution. Both things are likely to be crucial in the near-future as the traditional broadcast industry faces increasing downward pressures. This brief overview will provide an introduction to NGA on the basis of “what might be possible” and will serve as a jumping off point for Jeff and Ron’s presentations.

Part 2
Dolby AC-4: A State-of-the-Art Efficient, Flexible and Intelligent Audio System Supporting Immersive & Personalized Experiences

Video entertainment is entering a new era, with viewers increasingly seeking flexibility in what they watch, when they watch it, and how they choose to engage with it. To meet the demands of these new consumption patterns and provide flexibility for continued innovation, a new generation of audio delivery technology is required.

This presentation will provide an overview the technical features and capabilities of the Dolby AC-4 audio delivery system.

  • AC-4 is a new audio format that addresses the current and future needs of next-generation video and audio entertainment services, including those being delivered via broadcast and/or Internet streaming.
  • AC-4 has been standardized with the European Telecommunications Standards Institute (ETSI TS 103 190), adopted for use by Digital Video Broadcasting (DVB) in TS 101 154 and is proposed for use in ATSC 3.0 applications.
  • AC-4 also supports efficient delivery of more lifelike experiences by fully supporting 3D spatial representations (immersive sound) which are the basis for creating new opportunities to enhance the audio experience for consumers from the living room to headphone playback as well as enabling – for the first time – advanced personalization of the user experience.
Part 3
Introducing MPEG-H Audio

With consumers viewing and hearing content on more devices and in more places than ever before, broadcasters are increasingly pressured to meet demands for new and better experiences in a cost-effective manner. Consequently, broadcasters are assessing the capabilities of existing infrastructures and determining how new developments in audio and video technology will affect their ability to deliver enhanced services to a broad array of end-user technologies from high-end home theaters, to tablets and smart phones.

This presentation will show how the MPEG-H Audio standard allows broadcasters to meet these challenges by elevating the sound quality of their offerings beyond 5.1 Surround Sound while incorporating new groundbreaking interactive features in a rapid and cost-effective manner.

Pizza and pop dinner is provided at 6:30 pm.  Meeting starts promptly at 7:00 pm.
