The ORPHEUS Project – Building the Workflow for End-to-End Object-Based Audio Broadcasting
Driven by the technological challenges of the media landscape, as well as new user expectations and demands, the so-called ‘object-based’ audio technology has been developed. Object-based media is a revolutionary approach for creating and deploying interactive, personalised, scalable and immersive content.
ORPHEUS is a H2020-funded EU project involving ten European major players – broadcasters, manufacturers and research institutions – sharing the common vision to make the best use of this technology for both broadcasters and end users. During a 30-month run-time, the consortium develops, implements and validates an object-based end-to-end media chain for audio content in a real-life broadcast environment. ORPHEUS is driven by two pilots to demonstrate both linear and non-linear audio experiences using an IP-based custom-built broadcast chain.
This article presents an overview of the basic architecture, explains the challenges in developing this system and outlines the innovative tools that were created for recording, mixing, monitoring, storing, distributing, playing-out and rendering of object-based audio.
