Audio-over IP Transport Tool To Arrive From GatesAir


For those who attended the 2018 IBC Conference, a preview demonstration of “a scalable, multichannel audio over IP transport solution that addresses the convergence of broadcast operations with IT infrastructure” was part of the vendor offerings.

At the 2019 NAB Show, this tool will get its official introduction to the broadcast media industry.

Introducing Intraplex Ascent from GatesAir. It offers a direct connection to traditional digital and analog audio interfaces, and is compliant with both the AES67 standard and today’s leading AoIP networking solutions (Ravenna, LiveWire+ and Dante).

Ascent is available in two form factors: a 1RU server, with configurable options for physical and AES67 channels; and a software-only solution that operates in a virtualized container. Both versions support up to 32 audio channels (AES3, AES67, analog) and are interoperable with most Intraplex Audio over IP codecs.

GatesAir will demonstrate each at its NAB booth (N3303) from April 8-11 at the Las Vegas Convention Center.


The software-defined innovation is GatesAir’s first Intraplex system to live on a COTS x86 server, and provides broadcasters with a highly scalable, redundant and cloud-based transport platform for multichannel contribution and distribution. The platform streamlines installation and management by removing the need for many separate codecs and auxiliary hardware components, freeing multiple equipment racks in enterprise-level facilities.

Ascent adds further value by allowing users to manage many Secure Reliable Transport (SRT) streams on a centralized platform. SRT is a low-latency open source media streaming protocol which provides packet encryption and re-transmission capabilities for reliability and security. To further strengthen stream robustness and reliability, Ascent integrates Dynamic Stream Splicing (DSS), an Intraplex technology that diversifies SRT data across redundant networks. The addition of DSS to SRT will add protection against certain types of packet losses and complete network failures.

“Audio over IP has become a widely accepted technology, with a growing number of hardware and software solutions for broadcasters to choose from,” said Keyur Parikh, VP/GM for the Intraplex Product Line. “As an early innovator of Audio over IP codecs and networking solutions for broadcasters, GatesAir is taking the next logical step for our customers with direct integrationinto the IT infrastructure. With our Dynamic Stream Splicing application and SRT capability to fortify stream security and reliability, our customers now have a simple platform to manage many channels coming in and out of the studio or headend – all on a single, highly-redundant, multi-core server.”
