The ORPHEUS consortium has identified a number of standardisation bodies and contribution areas which are highly relevant for ORPHEUS. The targeted standardisation bodies have in common that they develop standards related to object-based audio. Thus, ORPHEUS is focusing its standards-related efforts to the selected bodies, in order to achieve maximum impact.
The standardisation activities by ORPHEUS so far have been focused mainly on four organisations, including three standardisation bodies – ITU-R, ISO/IEC MPEG, and ETSI-DVB – and the EBU as a standards-related organisation. In Q4/2017, new activities in the AES Standards Committee have started. In respect to these standardisation bodies, ORPHEUS partners performed the standardisation activities summarised in the table below.
|Standardisation body||Contributions||Involved partners||Standard impacted by ORPHEUS|
|ITU-R 6B||Work on updates on ADM Metadata||FHG, BBC, IRT||ITU-R BS.2076, ITU-R BS.2094|
|ITU-R 6B||Contributions on a streamable version of the ADM||FHG, BBC, IRT||Not yet defined, under development|
|ITU-R 6C||Work on the topic of a standardised baseline renderer for object-based audio (RG33)||FHG, BBC, IRT||Not defined|
|ITU-R 6C||Work for standardisation of object-based loudness calculation||FHG, BBC, IRT||ITU-R BS.1770|
|ISO/IEC MPEG||MPEG-H 3D Audio (audio codec)||FHG||ISO/IEC 23008-3|
|ISO/IEC MPEG||MPEG-H, DASH (transport container)||FHG||ISO/IEC 23009-1|
|ISO/IEC MPEG||Contribution to MPEG-I discussions on immersive media formats||b<>com||MPEG-I|
|EBU||Contributions to SP-FAR (Future Audio formats & Renderer) group meetings, planning of “Object Based Audio” workshop||BBC, IRT, FHG, b<>com||Does not apply, as EBU does not define formal standards|
|ETSI-DVB||Work on document ETSI 101154 to get a next generation audio part||FHG, BBC, IRT, b<>com||MPEG-H & AC-4|
|AES Standards Committee||Contributions to drafting will be made, and guidance given, as becomes necessary to ensure compatibility with the ORPHEUS architecture, in particular with ADM (Rec. ITU-R BS.2076).||BBC||AES-X242 (Streaming audio metadata over IP networks)|
