Calrec Audio Ready to Unveil Technologies for Video-over-IP and Audio-over-IP

By CIOReview | Thursday, March 10, 2016

FREMONT, CA: Calrec Audio is all set to launch multiple technologies at the NAB Show 2016 that will help driving broadcasters to interact with several protocols at the same time. These technologies will provide unique and all-round flexibility to different types of audio and video standards.

Calrec at NAB 2016 will display four new networking interfaces that include an AVB interface, an AES67/Ravenna interface, modular I/O Dante Card with extended AES67 compatibility. A new video interface named as SMPTE 2022-6 will also be launched in the event.

"We're drawing a line in the sand with these products," said Dave Letson, Vice President, Sales, Calrec. "We had held back on publically stating Calrec's formal direction on AoIP until we had properly assessed the market and talked to our customers. We strongly feel that it is not the role of a manufacturer to dictate which route to take, but to facilitate the broadcasters' choices.”

Each signal will be benefited from the management capabilities inherited in the Hydra2. Remote environments with interconnected multiple trucks facilities will specially be benefited from the new capability of Hydra2. Calrec is now capable of controlling multiple units of operation across different formats. Each of the Calrec protocol elements automatically connects to the Hydra2 network and resembles any other I/O resource available on the Hydra2 platform. The management tools in the Hydra2 integral suite provides additional advantages in allowing port protection, virtual Patchbays, alias files, access rights and remote configuration patching.

The AVB and AES67/Ravenna interfaces are 1U box capable of transporting 256 audio channels on an individual connection. The second expansion card adds one of the highest bandwidth of 512 channels. The box inherits the property that allows concurrent operations of different formats.

The modular I/O card, SMPTE 2022 has a port of 10GB that is capable of receiving up to four 3G, SD or HD video streams that de-integrates 16 audio channels from each port. Each of the video stream can be completely retransmitted or can be embedded with new audio. The 10GB secondary port provides SMPTE 2022-7 defined hitless switching.

The current Dante modular I/O card of Calrec, introduced at IBC 2014, employs Brooklyn II card of Audinate and provides AES67 standard support. This partnership offers easy-access of about 64 bi-directional channels in either of the protocol. This latest interface range defines Calrec’s position in the current environment looking for latest audio transport protocols. By this league of solutions, Calrec will support broadcasters with the service to utilize any combination of formats at any given time.
