Digital audio interface - Part 1: General

IEC 60958-1:2021 is available as IEC 60958-1:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60958-1:2021 describes a serial, uni-directional, self-clocking interface for the interconnection of digital audio equipment for consumer and professional applications. It provides the 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, multimedia technologies, or signals coded using non linear PCM. The format specification for these applications is not part of this document. The interface is intended for operation at audio sampling frequencies of 32 kHz and above. Auxiliary information is transmitted along with the programme. IEC 60958-1:2021c ancels and replaces the third edition published in 2008, and Amendment 1:2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The relevant part of IEC 60958-5 is supported.

Digitalton-Schnittstelle - Teil 1: Allgemeines

Interface audionumérique - Partie 1: Généralités

IEC 60958-1:2021 est disponible sous forme de IEC 60958-1:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. L'IEC 60958-1:2021 décrit une interface série unidirectionnelle et autosynchronisante pour l'interconnexion des appareils audionumériques destinés aux applications grand public et professionnelles. Elle fournit la structure de base de l'interface. Les points spécifiques à des applications particulières sont définis dans des documents distincts. Cette interface est essentiellement destinée à acheminer des programmes monophoniques ou stéréophoniques, qui utilisent un codage MIC linéaire et une résolution jusqu'à 24 bits par échantillon. Lorsqu'elle est utilisée à d'autres fins, cette interface est capable d'acheminer des données audio codées autres que des échantillons audio à codage MIC linéaire. Des dispositions ont également été prises pour permettre à l'interface d'acheminer des données relatives à des logiciels, des technologies multimédias ou des signaux à codage MIC non linéaire. La spécification du format de ces applications ne relève pas du présent document. L'interface est destinée à fonctionner à des fréquences d'échantillonnage audio supérieures ou égales à 32 kHz. Des informations auxiliaires sont transmises avec le programme. L'IEC 60958-1:2021 annule et remplace la troisième édition parue en 2008, et l'Amendement 1:2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) la partie pertinente de l'IEC 60958-5 est prise en compte.

Digitalni zvokovni vmesnik - 1. del: Splošno (IEC 60958-1:2021)

Ta del standarda IEC 60958 opisuje serijski, enosmerni vmesnik s samodejno sinhronizacijo za povezovanje digitalne avdio opreme za profesionalno in potrošniško uporabo.
Podaja osnovno strukturo vmesnika. V ločenih dokumentih so opredeljene postavke, značilne za posamezno vrsto uporabe.
Vmesnik je v prvi vrsti namenjen prenašanju enokanalnih ali večkanalnih programov, kodiranih prek linearnega zvoka PCM in ločljivostjo z največ 24 biti na vzorec.
Kadar se vmesnik uporablja za druge namene, lahko prenaša zvočne podatke, kodirane v drugi obliki, kot so zvočni vzorci z linearnim kodiranjem PCM. Predvideno je tudi, da se vmesniku omogoči prenašanje podatkov, povezanih z računalniško programsko opremo, večpredstavnostnih tehnologij ali signalov, kodiranih prek nelinearnega zvoka PCM.
Specifikacija oblik zapisa za tovrstne načine uporabe ni del tega dokumenta.
Vmesnik je namenjen delovanju pri frekvencah vzorčenja zvoka 32 kHz in višjih. Pomožne informacije se prenesejo skupaj s programom.
