This demonstration introduces the use of orchestrated media devices and object-based broadcasting to create immersive spatial audio experiences. Mobile phones, tablets, and laptops are synchronised to a common media timeline and contribute one or more individually delivered audio objects to the overall mix. A rule set for assigning objects to devices was developed through a trial production—a 13-minute audio drama called The Vostok-K Incident.

The same timing model as in HbbTV2.0 media synchronisation is used, and future work could augment linear television broadcasts or create novel interactive audio-visual experiences for multiple users. The demonstration will allow delegates to connect their mobile phones to the system. A unique mix is created based on the number and selected locations of connected devices.
