Your Practical Guide to AES67—Part 2

 

The AES67 standard is sometimes misunderstood as the specifications on how all professional digital audio gear is supposed to work and interconnect. Not exactly. In fact, AES67 simply defines the requirements for high-performance AoIP (Audio-over-IP) interoperability. A manufacturer can implement AES67 anyway it wants, and there’s the rub.

Review: Genelec 8430A IP SAM

Nigel Palmer heads down to Scrub’s new demo facility to have a play around with this monitoring ‘world first.’

 

When a set of loudspeakers is sent to me for review, testing usually takes place in my purpose-built space at Lowland Masters. In its natural state the room is one of the better ones I’ve heard, but in recent years I’ve been able to improve on that with the addition of a DSP-based Trinnov loudspeaker and room optimiser system

Audio networking: AES67 and AES70 on the rise

Although AES67 adoption is set to accelerate during 2016, the focus of the standards discussion is bound to shift towards AES70 – the forthcoming control protocol architecture that went out for public comment in November and became a published standard early in the new year. The extent to which AES70 will complement AES67 has been a matter of some debate, so a concise clarification – from Andreas Hildebrand, senior product manager at RAVENNA technology developer ALC NetworX – is very welcome.

GatesAir Strengthens IP Networking Strategy for Connected Studios

 

VMXpress IP launch establishes a foundation to extend robust GatesAir networking architectures into a true interoperable Audio over IP environment

Cincinnati, OH, March 09, 2015

 

GatesAir, a global leader in wireless, over-the-air content delivery solutions for radio and TV broadcasters, is extending the networking capabilities of its VistaMax™ portfolio with VMXpress IP, an AES67-compliant audio and logic device that establishes a standards based Audio over IP gateway for radio studios.  Leveraging the non-proprietary nature of ALC NetworX’s Ravenna networking technology, VMXpress IP drives interoperability across the studio and signal transport architecture through its open, standards-based foundation. GatesAir will introduce VMXpress at the 2015 NAB Show, taking place April 13-16 at the Las Vegas Convention Center (Booth C3107).

 

VMXpress IP evolves the robust networking architecture of GatesAir audio distribution and consoles, seamlessly integrating with existing and emerging AES67-compliant devices to help broadcasters build the optimal connected studio facility. Using the tremendous flexibility of open-standards IP networking, VMXpress IP simplifies connectivity with audio processors, satellite receivers, phone systems and studio support equipment, including program delays, among other key systems. With GatesAir’s existing network-based, minimally-wired studio networking architecture at the core, Ravenna’s networking technology fortifies the overall infrastructure through low-latency distribution and full signal transparency. Overall, broadcasters will enjoy a highly reliable and flexible network to move audio and data facility-wide.

 

Beyond the studio, VMXpress IP extends networking to leading IP transport solutions, including GatesAir Intraplex® IP Link codecs, for low-latency audio contribution and distribution. This expands connectivity to transmitter facilities (STL), live remote broadcast sites, and the internet for streaming content to other studios and the web. Therefore, the limitations of AES and analog connectivity are eliminated, instead leveraging intelligent networking with IP transport systems by using AES67 over the local Ethernet.

 

“With thousands of stations relying on GatesAir’s robust studio networking solutions, including seven of the top 10 billing stations in the US, adopting a standards-based approach to the rapidly evolving transition to IP is critical,” said Rich Redmond, chief product officer, GatesAir. “VMXpress IP represents our extension of GatesAir’s robust studio networking into this greater, highly flexible and interoperable Audio over IP environment, simplifying how our customers create, operate, scale and drive revenue within digital studio facilities.”

 

VMXpress IP continues GatesAir’s market leading strategy of using single network-based connections (Cat5/6) to move hundreds of audio and data signals across a multipoint network, ensuring a clean studio design that is easy to deploy, operate and scale as requirements evolve.

Back from NAB

RAVENNA's appearance @ this year's NAB has been another big success! RAVENNA was perceptible from practically anywhere within the Broadcast audio section of the Central hall - the RAVENNA booth was clearly visible, shining in bright white, and numerous RAVENNA flags identifying RAVENNA partners were prominently placed throughout the aisles. The RAVENNA booth was worth a visit as all currently available RAVENNA-enabled products were on display. Needless to say that all products were in fully networked operation, demonstrating the RAVENNA capabilities.


Amongst already available RAVENNA-enabled products from Axia, DirectOut, Lawo & Merging Technologies, NAB visitors could witness a world premiere: SOUND4 introduced the first RAVENNA PCIe sound card for Windows! Also, on preview: Digigram's multi-network PCIe card supporting RAVENNA, Livewire and EtherSound, AETA's Scoop5 with RAVENNA option and the RAVENNA Virtual Sound Card Driver for Windows by ALC NetworX, which will be released for free download soon!


Another focus was on X192: While AES X192 Task Group chair Kevin Gross was present on the RAVENNA booth, ready to to answer all questions on X192 and how RAVENNA relates to it, ALC NetworX' Andreas Hildebrand gave a well-received presentation on the activities and status of X192 work during NAB's Broadcast Engineering Conference. For those who missed this opportunity, here's a quick overview on X192 and its relation to RAVENNA.
