IEC EN 60958-4-2 Digital Audio Interface - Part 4-2: Professional Applications - Metadata and Subcode

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60958-4-2 testing. IEC EN 60958-4-2 specifies the format of encoding metadata or subcodes related to and carried with audio content. This part of IEC EN 60958 together with IEC EN 1-60958, IEC EN 4-1-60958 and IEC EN 4-4-60958 is for serial digital transmission of two channels of periodically sampled and linearly represented digital audio data from a transmitter. specifies an interface.

The two-channel digital audio interface is widely used in a variety of professional audio applications that go beyond the vision of the original standard. It is mainly used for applications using increased sampling frequencies and alternative physical media.

Breaking down the standard into independently maintainable parts allows for the introduction of additional transmission medium in the future, for example by revising IEC EN 60958-4-60958 without affecting other parts of the IEC EN 4-4 series.

It includes the following important technical changes according to IEC EN 60958-4:

• Support for a wider range of physical media;
• Support for a wider range of audio sampling frequencies;
• Deprecation of the "minimum practice" of channel state data.
