This recommendation formalises the EBU's position that the renderer and codec, including bit stream and associated technical and descriptive metadata be specified and standardized as part of Next Generation Audio systems based on audio-objects.
The EBU perceives risks in not specifying a renderer as part of a Next Generation Audio system based on audio objects; in particular:
- The support of content providers for NGA may be lost because the practical and cost implications will outweigh the benefits of using this new technology.
- Content providers will be bound to specific vendors and both the archive and contemporary productions will rely on formats that cannot be reproduced without vendor-specific technology.
- Programme exchange will be severely compromised if broadcasters use different systems; exchange will rely on the willingness of the vendors to allow and build interfaces between systems.
The EBU therefore recommends that the renderer and codec, including bit stream and associated technical and descriptive metadata be specified and standardized as part of Next Generation Audio systems based on audio-objects.
Please note that on 25/05/2016, a footnote stating that the ITU-R has published Report ITU-R BS.2266 describing object-based, scene-based and channel based options for NGA systems was added for clarification. The text of the document is unaltered.
