What is this BS EN 60958-4-2 - Professional applications for digital audio about ?
BS EN 60958-4-2 discusses digital audio interface with a focus on professional applications. BS EN 60958-4-2 is the fourth part of the BS EN 60958 multi-series on the digital audio interface that specifies the format for coding metadata, or subcode, that relates to the audio content and is carried with it.
BS EN 60958-4-2 provides a fundamental level of implementation that should prove sufficient for general applications in professional audio or broadcasting. BS EN 60958-4-2 defines two implementations that are standard and enhanced. These terms are used to communicate in a simple manner the level of implementation of the interface transmitter involving the many features of channel status.
Who is BS EN 60958-4-2 - Professional applications for digital audio for ?
BS EN 60958-4-2 on professional applications for digital audio is useful for:
- Manufacturers of products that provide audio output (televisions, phones)
- Audio equipment manufactures
- Audio programmers
- Sound technicians
- Recording and dubbing studios
Why should you use BS EN 60958-4-2 - Professional applications for digital audio ?
The two-channel digital audio interface has been widely used in a variety of professional audio applications that have reached beyond the vision of the original standard. In particular, applications using increased sampling frequencies and alternative physical media. BS EN 60958-4-2 specifies the format for information, metadata, or subcode transmitted with the audio data principally the "channel status" but also user data and the auxiliary bits. Implementors will note that the current implementation options ("Standard" and "Enhanced") both require that status data be implemented correctly in compliant equipment.
Together with IEC 60958-1, IEC 60958-4-2, and IEC 60958-4-4, BS EN 60958-4-2 specifies an interface for serial digital transmission of two channels of periodically sampled and linearly represented digital audio data from one transmitter to one receiver.
What’s changed since the last update?
BS EN 60958-4-2:2016 supersedes IEC 60958-4:2003, which is withdrawn. BS EN 60958-4-2:2016 includes some technical changes with respect to IEC 60958-4:2003.
These include:
- Support for a wider range of physical media
- Support for a wider range of audio sampling frequencies
- Deprecation of “minimum implementation” of channel status data
