DIN EN 61937-1:2012-08

This part of IEC 61937 applies to the digital audio interface using the IEC 60958 series for the conveying of non-linear PCM encoded audio bitstreams. It describes a way in which this digital interface can be used in consumer applications. The IEC 60958 interface format consists of a series of IEC 60958 subframes. Each IEC 60958 subframe is usually used to transfer a linear PCM sample value; it can also be used to convey data words. The non-linear PCM encoded audio bitstreams to be transferred via this interface are arranged in data bursts. Each data burst consists of a 64 bit burst-preamble, followed by the burst payload. The burst-preamble consists of a sync-word, information about the burst payload and the bitstream number. The interface can transfer one or several bitstreams. Each type of bitstream can place special requirements on the repetition period of the data-burst forming the bitstream. The professional mode (AES/EBU) is not considered within the scope of this standard. The responsible committee is K 742 "Audio-, Video- und Multimediasysteme, -geräte und -komponenten" ("Audio, video and multimedia systems, equipment and components") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
