- Abstract
- A new television audio system based on the MPEG-H Audio standard is being designed and tested to offer interactive and immersive sound, employing the standard’s audio objects, height channels, and higher order Ambisonics features. Object-based interactive audio offers users the ability to personalize their listening experience, setting their preferred language and dialogue level, or selecting elements to hear their home team or listen to their favorite race driver’s radio. A four-stage process is introduced for implementing the complete system in TV networks. Additionally, the plant design, creative, and operational implications of producing content are discussed, based on the design and field testing of the system. Consumer reproduction implications are also presented, such as a 3D Soundbar prototype, the control of loudness in the system, and rendering for playback on both traditional and new media devices.

bio
Robert Bleidt is division general manager of Fraunhofer USA Digital Media Technologies. He is the inventor of the award-winning Sonnox/Fraunhofer codec plug-in, widely used in music mastering, led the extension of Fraunhofer’s codec business to a open-source model by inclusion in Android, and developed Fraunhofer’s Symphoria automotive audio business. Before joining Fraunhofer, he was president of Streamcrest Associates, a product and business strategy consulting firm in new media technologies. Previously, he was director of product management and business strategy for the MPEG-4 business of Philips Digital Networks and managed the development of Philips’ Emmy-winning asset management system for television broadcasting. Prior to joining Philips, Bleidt served as director of marketing and new business development for Sarnoff Real Time Corporation, a video-on-demand venture of Sarnoff Labs. Previously, he was director of mass storage technology and inventor of SRTC’s Carousel algorithm. Before joining Sarnoff, Bleidt was President of Image Circuits, a consulting engineering firm and manufacturer of HDTV research equipment.Arne Borsumbio
Arne Borsum studied media technologies at the Ilmenau Technical University, Germany, before starting as a research engineer at Fraunhofer in 2004. After a short engagement at the Fraunhofer IDMT in Ilmenau, he joined the Audio and Multimedia division of the Fraunhofer IIS in Erlangen, Germany. Borsum worked on various projects in the field of digital audio processing, audio coding, software development and DSP implementation. His speciality became downmixing technologies, loudness, dynamic range control and related metadata solutions. As a technical expert in the field of audio for broadcasting, his focus of work evolved into application engineering for TV and the workflow in broadcast infrastructures in order to establish Fraunhofer audio technologies in these services. Further, he represented the Audio and Multimedia division of Fraunhofer IIS in standardization bodies and committee groups such as EBU, IEC, HDMI Forum and AES. In 2013, Borsum was appointed senior engineer. From April 2014, he worked as independent contractor for Fraunhofer IIS, acting as business development manager for audio production. In this role, he continued his work in application engineering and committee work with focus on the integration of MPEG-H Audio into broadcast infrastructures. Since February 2015, Borsum works for Innovationszentrum für Telekommunikationstechnik (IZT) in Erlangen, Germany, as product manager for Digital Audio Broadcasting.Harald Fuchsbio
Harald Fuchs received his diploma in electrical engineering from the University of Erlangen, Germany in 1997 and joined Fraunhofer IIS in the same year. From 1997 to 2002 he was a software developer for video codecs and multimedia streaming systems. From 2002 onwards he concentrated on multimedia systems aspects and standardization. He actively contributed to several standardization organizations (including MPEG, DVB and HbbTV), and was author or co-author of several standards documents and IEEE papers. Since 2009 he focused on audio technologies for broadcasting and broadband streaming applications. Since 2011 he has been senior business development manager, audio for TV Broadcast.S. Merrill Weissbio
S. Merrill Weiss is a consultant in electronic media technology and technology management with over 48 years of experience in broadcast operations and in designing facilities for radio and television stations, television networks, major studios, and similar organizations. He has spent more than 38 years in developing technology for digital audio and video and in helping to write standards for its implementation, having produced the SMPTE/EBU tests that led to the first digital television standard, upon which practically all subsequent digital video standards are based. He is a SMPTE Fellow, received the SMPTE David Sarnoff Gold Medal Award and the SMPTE Progress Medal, received the NAB Television Engineering Achievement Award and the ATSC Bernard J. Lechner Outstanding Contributor Award, received the IEEE Broadcast Technology Society Matti S. Siukola Award twice, and is recognized by the Society of Broadcast Engineers as a Certified Professional Broadcast Engineer. Weiss holds six patents for broadcast transmission technology and is a graduate of the Wharton School of the University of Pennsylvania. - Keyword(s)
