Consumer audio/video equipment - Digital interface - Part 6: Audio and music data transmission protocol

This part of IEC 61883 describes a protocol for the transmission of audio and music data
employing IEEE 1394 and specifies essential requirements for the application of the protocol.
This protocol can be applied to all modules or devices that have any kind of audio and/or
music data processing, generation and conversion function blocks. This standard deals only
with the transmission of audio and music data. The control, status and machine-readable
description of these modules or devices should be defined outside of this standard according
to each application area.

Audio-Video-Geräte der Unterhaltungselektronik - Digitale Schnittstelle - Teil 6: Übertragungsprotokoll für Ton- und Musikdaten

Matériel audio/video grand public - Interface numérique - Partie 6: Protocole de transmission de données audio et musicales

L'IEC 61883-6:2014 décrit un protocole de transmission de données audio et musicales qui utilise l'IEEE 1394 et spécifie les exigences essentielles pour l'application du protocole.
Ce protocole peut être appliqué à tous les modules ou dispositifs d'un type quelconque de traitement, génération et blocs de fonction de conversion de données audio et/ou musicales. La présente norme ne traite que de la transmission de données audio et musicales. Il convient de définir en dehors de la présente norme le contrôle, l'état ainsi qu'une description lisible par une machine de ces modules ou dispositifs, selon chaque domaine d'application.
L'IEC 61883-6:2014 annule et remplace la deuxième édition, publiée en 2005, dont elle constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) la couche d'adaptation à une séquence AM824 pour l'application du disque Blu-ray a été ajoutée;
b) la méthode de transmission avec blocage est devenue normative;
c) les protocoles précédemment définis ont été inclus à des fins de rétrocompatibilité.

Porabniška avdio/video oprema - Digitalni vmesnik - 6. del: Prenos zvokovnih in glasbenih podatkov

Ta del standarda IEC 61883 opisuje protokol za prenos zvokovnih in glasbenih podatkov, skladnih s standardom IEEE 1394, in določa bistvene zahteve za uporabo protokola. Ta protokol je mogoče uporabiti za vse module ali naprave, ki vključujejo kakršne koli funkcijske bloke za obdelavo, generiranje in pretvorbo zvokovnih in/ali glasbenih podatkov. Ta standard obravnava le prenos zvokovnih in glasbenih podatkov. Nadzor, status in strojno berljiv opis teh modulov ali naprav naj bodo definirani zunaj tega standarda v skladu s posameznim področjem uporabe.
