PRESENTATION AND ABSTRACT: Telco service providers face significant new challenges for audio delivery in next generation broadcast systems such as IPTV. These include the capability to deliver soundtracks from mono to 5.1-channels and beyond with greater efficiency than current systems. The session will discuss the requirements for an audio coding scheme to address both near- and long-term technology challenges of IPTV broadcasting, such as delivering HDTV over IP. Attendees will understand the various factors to be considered in determining the characteristics of a suitable audio coding scheme. Participants will learn how to maintain full control over the listening experience for all consumer environments through comprehensive metadata control and standardized connectivity. Attendees will also understand how to deal with the many requirements posed by multichannel audio, how to facilitate the integration of a new audio codec with a broadcast production environment, and how to offer performance improvements for the consumer, while ensuring simple integration into the consumer listening environment. ADDITIONAL INFORMATION: The session will cover the factors to be considered in determining the characteristics of a suitable audio coding scheme, including requirements for new IPTV and broadcast services such as HDTV and services using advanced video codec such as H.264 or VC-1; opportunities for improving the audio performance of current IPTV broadcast services; the impact of a new audio coding scheme on broadcast production practices; the impact of a new audio coding scheme on consumer hardware and listening environments; and differentiation between IPTV and competitive TV services. For example, the discussion about how providers can prepare for the demands of future broadcast services will include an overview of requirements such as the ability to deliver audio quality improvements to match video quality improvements of high-definition IPTV broadcasting; fl
