Universal serial bus interfaces for data and power - Part 1-8: Common components - USB Audio 3.0 device class definition terminal types

IEC 62680-1-8:2019 is to describe in detail all the Terminal Types that are supported by the Audio Device Class. This document is considered an integral part of the Audio Device Class Specification, although subsequent revisions of this document are independent of the revision evolution of the main Audio Device Class Specification. This is to easily accommodate the addition of new Terminal Types without impeding the core Audio Device Class Specification.
The Audio Device Class Definition applies to all devices or functions embedded in composite devices. All audio signals inside an audio function start at an Input Terminal, pass through some Units, and leave the function through an Output Terminal. Units can manipulate the signal in various ways. Terminals represent the connections of the function to the outside world.
As part of the Terminal descriptor, the wTerminalType field specifies the vendor’s suggested use of the Terminal. For example, a pair of speakers is a more suitable target for music output than a telephone line. This feature allows a vendor to ensure that applications use the device in a consistent and meaningful way.

Interfaces de bus universel en série pour les données et l'alimentation électrique - Partie 1-8: Composants communs - Définition de classes de dispositifs USB Audio 3.0 pour types de terminaux

L'IEC 62680-1-8:2019 a pour objectif de décrire en détail tous les types de terminaux pris en charge par la classe des dispositifs audio. Le présent document est vu comme faisant partie intégrante de la Spécification de classe de dispositifs audio, bien que les révisions ultérieures du présent document soient indépendantes de l'évolution des révisions de la Spécification de classe de dispositifs audio principale. L'objectif est de faciliter la prise en compte de l'ajout de nouveaux types de terminaux sans affecter la Spécification de classe de dispositifs audio de base.
La définition de classes de dispositifs audio s'applique à tous les dispositifs ou fonctions intégrés dans des dispositifs composites. Tous les signaux audio au sein d'une fonction audio partent d'un terminal d'entrée, passent par des unités, puis quittent la fonction par un terminal de sortie. Les unités peuvent manipuler le signal de différentes façons. Les terminaux représentent les connexions de la fonction au monde extérieur.
Le champ wTerminalType, qui fait partie du descripteur de terminal, indique l'utilisation suggérée par le fournisseur du terminal. Par exemple, une paire de haut-parleurs est une cible plus appropriée pour une sortie musicale qu'une ligne téléphonique. Cette fonctionnalité permet à un fournisseur de s'assurer que les applications utilisent le dispositif de manière cohérente et pertinente.
