- Abstract
- Personalized, immersive audio provides the next wave of enhancement to the broadcast experience. Next-generation audio broadcast systems let content owners create and deliver more audio than can be sent through a traditional broadcast channel. Consumers can tailor their broadcast audio through interactive control of additional sound elements such as alternate dialogue, ambience, and effects. Next-generation audio can also provide an improved experience by rendering to an extended range of playback systems including an overhead surround dimension. This article provides a technical overview of the technology, tools, and workflow developed for a next-generation broadcast audio system.

bio
Sripal Mehta is principal architect, broadcast at Dolby Laboratories. His focus is the innovation, development and deployment of next-generation audio. Mehta has spent 15 years at Dolby working in the areas of professional audio, digital cinema security, and playback, and most recently, object-based immersive and personalized audio for the cinema and home. As a member of SMPTE, he has authored two digital cinema standards and has chaired the digital cinema security subcommittee. Mehta holds bachelor’s and master’s degrees in electrical and computer engineering from Carnegie Mellon University.Thomas Zieglerbio
Thomas Ziegler received a Ph.D. in electrical engineering for his research on the optimization of digital signal processor architectures with respect to audio coding. After his academic career, he worked at the Fraunhofer Gesellschaft, FhG, in the field of hardware close development of high-efficiency audio codecs. In 2000, he joined Coding Technologies—the inventors of HE-AAC—where he led the implementation of HE-AAC playback for satellite-based and terrestrial digital radio as well as for mobile applications. Since the acquisition of Coding Technologies by Dolby in late 2007, Ziegler coordinated Dolby’s embedded strategy as director embedded engineering. Today, he is driving the playback side of Dolby’s Personalized Audio offerings in the broadcast space. Ziegler has contributed to many publications as principal or co-author, and for many years, he gave lectures at the University of Fulda on source coding for multimedia. - Keyword(s)
