Emerging Technology Trends Report Dante Q-LAN EBU N/ACIP
Emerging Technology Trends Report AES Technical Committee on Network Audio Systems November 2011 Editor, Tim Shuttleworth; [email protected] This document is a compilation of contributions from numerous members of the Technical Committee on Networked Audio Systems. The committee has identified the following important topics related to emerging audio networking technologies. Technologies which have emerged since the last published Emerging Trends Report from the committee in 2007 are included. To provide structure to the report items are discussed in order of their maturity; commercialized technologies implemented in products available for purchase being discussed first and embryonic concepts in early development come up last. Other categorizations referred to in this document are consumer market orientation versus professional market focus, as well as media transport methods versus command and control protocols. Dante Dante is a media networking solution developed by Audinate. In addition to providing basic synchronization and transport protocols Dante provides simple plug and play operation, PC sound card interfacing via software or hardware, glitch free redundancy, support for AVB and support for routed IP networks. The first Dante product arrived in 2008 via a firmware upgrade for the Dolby Lake Processor and since then many professional audio and broadcast manufacturers have adopted Dante. From the beginning Dante implementations have been fully IP based, using the IEEE 1588-2002 standard for synchronization, UDP/IP for audio transport and are designed to exploit standard gigabit Ethernet switches and VoIP-style QoS technology (e.g. Diffserv). Dante is evolving with new networking standards. Audinate has produced versions of Dante that use the new Ethernet Audio Video Bridging (AVB) protocols, including IEEE 802.1AS for synchronization and RTP transport protocols. -

AES67 Standard and What It Means for the AV Industry
TECH TALK 78 Systems Integration Asia August - September 2015 About AES67 Standard And What It Means For The AV Industry AES67 is not intended to replace existing solutions, but to offer means for interoperability among them Many of you would have heard about the AES67 standard that was developed by the Audio Engineering Society and published in September 2013. To promote the adoption of AES67, The Media Networking Alliance (MNA) was formed in October 2014. SI Asia speaks to Andreas Hildebrand,Senior Product Manager at ALC NetworX GmbH, the company that is responsible for RAVENNA networking technologies and also a member of MNA, to know more about AES67.

Audio Sur Ip : Problématiques Et Perspectives D'évolution
ÉCOLE NATIONALE SUPÉRIEURE LOUIS LUMIÈRE Mémoire de fin d'études AUDIO SUR IP : PROBLÉMATIQUES ET PERSPECTIVES D'ÉVOLUTION Partie Pratique : Projet d'Ingénierie d'un studio polyvalent en audio sur IP Marie-Angélique MENNECIER Directeur interne : Jean ROUCHOUSE Directeur externe : Jean-Marc CHOUVEL Rapporteur : Franck JOUANNY 19 juin 2015 RÉSUMÉ : À l'heure où les réseaux audio sur IP professionnels se développent, une normalisation a été effectuée par le groupe de travail AES X192 afin de permettre leur interopérabilité. L'AES67 pose les bases nécessaires pour un fonctionnement commun, et les principales solutions existant sur le marché de l'audio sur IP professionnel s'y sont conformées depuis. La problématique de ce mémoire est l'analyse des implications techniques de l'audio sur IP et des mécanismes nécessaires à une interopérabilité concrète, tout en proposant une ouverture sur les possibilités de développements futurs de cette technologie protéiforme. Dans un premier temps, nous formulerons quelques rappels sur les réseaux IP qui nous serviront de socle technique pour analyser les protocoles existants, puis comprendre les fondations nécessaires à leur fonctionnement commun. Nous pourrons enfin dégager quels écueils peuvent entraver de futurs développements. mots clés : AoIP, audio sur IP, AES67, Dante, Ravenna, Livewire, interopérabilité, AVB ABSTRACT : At times when audio over IP networks have started growing and thriving, a standardization has been discussed by the AES X192 workgroup to insure that they would be interoperable. In 2013, AES67 defined such rules, and the main audio over IP professional networks have since complied. This dissertation analyzes the technical details of such a technology, how interoperability can be effectively achieved, and how audio over IP may evolve, in the future, from its current protean form. -
