An Object-Based Audio System for Interactive Broadcasting

This paper describes audio recording, delivery, and rendering for an end-to-end broadcast system allowing users free navigation of panoramic video content with matching interactive audio. The system is based on one developed as part of the EU FP7 funded project, FascinatE. The premise of the system was to allow users free navigation of an ultra-high definition 180 degree video panorama for a customizable viewing experience. From an audio perspective the complete audio scene is recorded and broadcast so the rendered sound scene at the user end may be customized to match the view point. The approach described here uses an object-based audio paradigm. This paper presents an overview of the system and describes how such a system is useful for facilitating an interactive broadcast.
