We’ve been
talking a lot in Radio World about networked audio lately; and it’s a topic that also
will take a prominent role at the upcoming AES convention in San
Francisco.
A new track of workshops will focus on
networked audio. They were organized by Track Chair Tim Shuttleworth in collaboration
with Nathan Brock, who passed away recently.
Audio Network Device Connection and Control — Chair, Richard Foss, Rhodes University; Panel: Jeff
Koftinoff: MeyerSound; Robby Gurdan, UMAN; Andreas Hildebrand, ALC NetworX;
Kieran Walsh, Audinate. Panelists will demonstrate “how they have enabled the
discovery of audio devices on local area networks, their connection management and
control over their various parameters. Issues related to streaming audio, such
as bandwidth management and synchronization, and connection management and
control protocols will be discussed.”
The Unified AV Network — Chair
Rob Silfvast, AVID. This panel is an overview of the AVnu Alliance, a consortium of audio and
video product makers and core technology companies. “Committed to delivering an interoperable open standard for
audio/video, networked connectivity, AVnu offers a logo-testing program that
allows products to become certified for interoperability,”
according to organizers. Representatives from member companies will provide insights about AVB technology
and participation.
Interoperability Issues
in Audio Transport Over IP-Based Networks — Chair, Tim
Shuttleworth; Panel: Lee Minich, Lab X Technologies/AVnu Alliance; Kevin Gross,
AVA Networks/AES X-192; Sonja Langhans, IRT Munich; Greg Shay, Telos/Axia. This workshop will focus on two key areas of audio/media
transport over IP based networks: Multichannel Audio distribution over Ethernet
LANs for low-latency, high-reliability interconnections in home, automobile and
commercial environments; and the interoperability of audio
contribution, over Internet Protocol (ACIP and ACIP2). “These issues will be
addressed from both the European and U.S. perspectives. Issues include
challenges and solutions in achieving reliable content distribution.”
Audio
Networks, a Paradigm
Shift for Broadcasters — Chair, Stefan Ledergerber, Lawo, Germany; Panel: Sonja
Langhans, IRT Munich; Andreas Hildebrand, ALC Networx; Lee Minich, Lab X
Technologies/AVnu alliance; Greg Shay, Telos/Axia; Kevin Gross, AVA
Networks/AES X-192.
With the emergence of a variety of audio networking technologies, many
broadcast organization workflow-related questions remain unanswered. This panel
will address a number of these hot topics e.g. Will traditional cross-point,
matrix switches (routers) be replaced by networks? Which component will deal
with signal processing, currently accomplished within audio routers?Which department is best equipped for handling
audio networks: audio or IT? And, how do we educate personnel to deal with
audio networks?
Error-Tolerant Audio Coding — Chair, David Trainor,
CSR; Panelists: Gary Spittle, Dolby; Deepen Sinha, ATC Labs (tbc) and Juergen
Herre, Fraunhofer IIS (tbc). Organizers cite key trends: “The increasing delivery of
real-time audio services over the Internet or cellular networks; and, the
variable capacity and reliability of these networks for real-time audio
streaming. This workshop will discuss the capabilities of error-tolerant audio
coding algorithms and, recent advances in the state of the art.”
Open IP Protocols for
Audio Networking — Chair, Kevin
Gross, CobraNet, QSC. The session is a tutorial to “address the conundrum
resulting from the networking and telecommunication
industry’s multiplicity of protocols for carriage of audio and video over IP
networks. These protocols have been widely deployed for telephony and
teleconferencing applications, Internet streaming and cable television. A
variety of these protocols and their capabilities and limitations will be
addressed.” They include IP, VoIP, IPTV, HTTP streaming, Real-time transport
protocol (RTP), RTCP and RTSP, and IEEE-1588 Precision time protocol (PTP).
Gross will also provide an overview of AES standards work, X192.
