DIGITAL AUDIO INTERFACE - PART 1: GENERAL (IEC 60958-1:2008, IDT)
MS IEC 60958-1:2011
Status : Original
Format : PDF

This Malaysian Standard describes a serial, uni-directional, self-clocking interface for the interconnection of digital audio equipment for consumer and professional applications.
It provides th ....Read more e basic structure of the interface. Separate documents define items specific to particular applications.

The interface is primarily intended to carry monophonic or stereophonic programmes,
encoded using linear PCM and with a resolution of up to 24 bits per sample.

When used for other purposes, the interface is able to carry audio data coded other than as
linear PCM coded audio samples. Provision is also made to allow the interface to carry data
related to computer software or signals coded using non-linear PCM. The format specification
for these applications is not part of this standard.

The interface is intended for operation at audio sampling frequencies of 32kHz and above.
Auxiliary information is transmitted along with the programme. Close
