Introduction

Imagine you could adapt the length of a radio documentary as you require or listen to a radio drama from the positions of different protagonists in the play. These and many more personalised, immersive listener experiences become possible due to a novel technological concept called object-based media, which will fundamentally change the production and user experience of radio broadcasts and multimedia productions.

Key toolsand apps for implementing object-based media for audio content have been developed by ORPHEUS, an EU-funded research project performed by ten major European media industry players. Broadcasting architectures and infrastructures have been developed, refined and optimised over the last 100 years. Up to now, the final product delivered to the audience, was assembled, edited,mixed and configured as an unchangeable entity, leaving little or no options for adjustments according to the reception conditions and the personal preferences of the recipient. The object-based media approach fundamentally changes this principle: A production is now a collection of media assets, so-called ‘objects’, along with parameters, or ‘metadata’, describing their attributes and relationship.

This package is delivered to an end-user device, where it gets optimally ‘rendered’ according to the capabilities of the device, environmental conditions and user preferences. On 15th May 2018, the ORPHEUS consortium presented their results at a workshop in Munich to about 120 representatives of the global media industry. The event was hosted by IRT, the research institute ofthe public broadcasters of Germany, Austria, and Switzerland. Below, we provide an overview on the final results and the demonstrations presented at the workshop.F or a more in-depth description of the project see [1, 2].
