THE PRESENTATIONS & SPEAKERS

10:00 Welcome / Ralf Neudel (IRT)

10:05 The Future of Audio is Object-based – Results of ORPHEUS / Andreas Silzle (FHG IIS)

Slides of presentation

The ORPHEUS project, funded under the HORIZON 2020 program by the European Commission, united ten major players of the European media industry.

In the past 30-month ORPHEUS has developed, implemented and validated a complete object-based media chain for audio content. We were running two successful pilots to demonstrate the key features and benefits of object-based broadcasting, including immersive sound, foreground/background control, language selection, and enhanced program services. Pilot 1 was the first ever object-based live interactive radio drama. In pilot 2 we introduced the variable-length feature in non-linear playback that offers users to adapt content in time or depth.

ORPHEUS’ technical coordinator Andreas Silzle explains the basic principles, gives an overview and outlines the specific challenges of the project.

10:35 The ORPHEUS Reference Architecture / Michael Weitnauer (IRT)

Slides of presentation

The object‑based approach to media gives the most fundamental opportunity to re‑imagine the creation, management and enjoyment of media since the invention of audio recording and broadcasting. This change, however, requires certain adaptations within the existing technical workflow of broadcasters. This talk presents an example of an end‑to‑end object‑based audio architecture which is based on open standards, defined by the ORPHEUS project consortium. The final reference architecture specification of ORPHEUS has been shaped by taking into account typical channel‑based broadcast workflows but, more importantly, by also including the knowledge and lessons learned during the pilot phases and stages.

14 Media Device Orchestration: ad-hoc arrays for spatrial audio / S3A

Immersive audio experiences usually need complex spatial audio systems. But our homes have many loudspeakers (smart assistants, laptops, mobiles, etc) that can form ad-hoc arrays. This demo of “Media device orchestration” (MDO) will use synchronised wireless connections to allow a radio drama to be reproduced on an ad-hoc array formed from a laptop and two mobiles.

15 User evaluation results from Josephs / BR & FHG IIS

Based upon the ORPHEUS project’s main pillars, the user requests and use cases, the pilot architecture and the pilots themselves, we have developed a basic model for practical examination and evaluation of user experience within an object-based media eco-system as a holistic model. This model is comprised of three main dimensions:

  • audio experience
  • usability experience
  • information experience

In this poster demo we explain the methodology, the setting at JOSEPHS® and the gained results.
