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

IEC 61883-6:2014(E) 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. This third edition cancels and replaces the second edition, published in 2005, and constitutes a technical revision. This edition includes the following changes: - AM824 sequence adaptation layer for Blu-ray Disc application is added. - Blocking transmission method becomes normative. - Previously defined protocols have been included for the sake of backwards compatibility.

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.

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.

Overview

EN 61883-6:2014 (IEC 61883-6:2014) defines an audio and music data transmission protocol for consumer audio/video equipment using the IEEE 1394 (FireWire) digital interface. The standard describes essential requirements for transporting audio/music data between modules or devices that perform audio processing, generation or conversion. It addresses only data transmission - control, status and machine‑readable device descriptions are intentionally out of scope and left to application‑specific specifications.

This third edition (2014) is a technical revision of the 2005 edition and: adds an AM824 sequence adaptation layer for Blu‑ray Disc, makes the blocking transmission method normative, and retains previously defined protocols for backwards compatibility.

Key topics and technical requirements

• Transport over IEEE 1394: Uses IEEE 1394 isochronous packet mechanisms for time‑sensitive audio streams.
• Protocol layers: Defines a reference model including application, adaptation, and packetization layers, plus CIP (common isochronous packet) headers.
• Packetization & timing: Specifies packet header formats, packet transmission methods, timestamp processing and transmission control (blocking and non‑blocking modes).
• Event types and formats: Covers AM824 generic format and specific payloads such as IEC 60958 bitstreams, multi‑bit linear audio (MBLA), one‑bit audio (e.g., SACD), MIDI, SMPTE time code, sample count, high‑precision floating point and ancillary/application data.
• FDF / SFC definitions: Frame and format descriptor (FDF) definitions, supplemental SFC tables, clock‑based and command‑based rate control modes.
• Adaptation layers: Includes sequence adaptation layers for DVD‑Audio, SACD, Blu‑ray Disc, MBLA and other application‑specific mappings.
• Backward compatibility: Previously defined protocols are included to support legacy devices.

Applications and who uses it

• Consumer audio/video device manufacturers implementing FireWire audio transport (e.g., Blu‑ray players, DVD‑Audio devices, SACD players, AV receivers, audio interfaces).
• Firmware and DSP engineers designing packetization, timestamping and adaptation layers for digital audio streaming.
• System integrators and OEMs requiring reliable isochronous audio transport and interoperability across IEEE 1394 networks.
• Test labs and compliance teams validating implementations against EN 61883‑6 requirements.
• Practical use cases: multichannel audio distribution, high‑resolution digital audio transfer, professional/consumer device interoperability, and media‑format specific streaming (Blu‑ray, SACD, DVD‑Audio).

Related standards

• IEC 61883‑1 (general reference model)
• IEC 60958 series (digital audio interface / PCM and consumer bitstreams)
• IEEE 1394 / IEEE 1394a (high‑performance serial bus)
• Previous edition EN 61883‑6:2005 (for historical compatibility)
