Even as moving AV signals (even industrial-strength video) over IP has moved from bleeding edge to mainstream, the industry still has a long way to go. Depending on your perspective, that involves either A) wringing out even more latency and other image quality glitches, and improving security features for a better final package delivered to the user, and/or B) educating both the AV integrator and the end user that sure, we need to do more of A, but we now have some robust solutions that solve a lot of our challenges today, with today’s gear.

David Shamir of Atlona demoed their new OmniStream system for AV over IP, showing the similarity of source material to the video delivered at the receiving end. 
Silicon Valley—home of Netflix, Google, and any number of companies that have mastered the art of moving squilabytes of data through digital pipe with astounding speed and efficiency—is a good place to launch a discussion on the state of AV over IP for the commercial AV world, and last Friday it was the place I got a personal demo of some interesting new solutions from a serious contender in that world. That contender is Atlona, which has been on the scene a while, and are some pretty eloquent spokesmen for both what’s available today for AV over IP for the commercial AV market as well as for the need to push the envelope to make it all even better. Atlona, with headquarters in San Jose, CA, has just this week announced a new solution, its OmniStream product family for AV over IP, that I saw in San Jose, and that InfoComm 2016 attendees will get to see in Las Vegas. Atlona believes its industry-exclusive features include the ability to supply redundant AV networks with independent data streams with cost-efficiency breakthroughs, and enterprise-grade network-error resilience and video compression with extremely low latency not achieved with previous technology. I had a chance to meet with David Shamir, director of product management at Atlona on Friday, and Shamir did a great job of putting not just Atlona's offerings but the larger issues in context.

“What we see as our goal,” said David Shamir, “are two things: to address the integrators that are already doing AV over IP; and to explain why the traditional circuit-based integrator may want to consider AV over IP. What are the issues for AV over IP today? As a system integrator, it’s not really about 'moving video over IP' as many people say. At InfoComm, you’ll see some 40-50 vendors all claiming to move video over IP. I say, it’s not about moving the video over IP. When you immerse yourself in packet-based switching, which is what IP is, there is more that you as a systems integrator need to take into consideration than just moving video over IP. In fact, that is the easy part. But when you as a system integrator approach IT guys, they speak a different language. Their religion is different. So if we want to go with IP trends, we need to speak their language.”

Having heard many technology industry analyses over the years, few people have offered a view as broad-ranging as Shamir’s, who spent less time explaining Atlona’s offering than explaining why the world is changing and who is at the forefront of the IP revolution. In fact, Shamir outlined specific changes going on inside the tech giants' offices in the Bay area, including a recent AV/IT makeover at eBay corporate headquarters where it transitioned everything to IP.

20-30 or more milliseconds of latency, depending on the application, results in poor delivery of high bandwidth video across an enterprise or across the country. So the need is obviously as little latency as possible, as Atlona demoed.

But I was down the street from eBay, at Atlona’s offices, to get a peek at what Atlona will be showing at InfoComm in June. In a refreshing break from usual product pitches, David Shamir virtually built with me an enterprise AV over IP system, where we populated each part with ideal solutions based on current demands from users. We built out the system, and the needs analysis. In a way, it was like reverse-engineering an ideal product, rather than starting with a product and then shoe-horning it into needs real or imagined.

With the luxury of more time than I’d ever have at a trade show like InfoComm, we were able to deconstruct a network, using as our model a corporate campus, with multiple buildings, with a need for delivery of sophisticated data and video to displays in:

• Meeting rooms

• Training rooms
• Internal TV
• Digital Signage

That’s the need. To build out the system, think not first of what gear you can sell in there; think first of what the customer needs:
• 4K/UHD capability
• Need for multichannel, not just a single channel network
• Redundancy for each network (not the strength of circuit-based systems)
• Security. Content, and encryption.
• PoE. Power over ethernet. With a 10G network? Can’t do it, today, with any switch. (Will AV over IP do it?)
• Error resilience. This is a purely technical term that addresses how and how quickly the system can rebuild lost bits of data on the receiving end of a network. The problem of error resilience is compounded with more need for scalability. The more machines on a network, the more error, based on the LAN’s inherent weaknesses as burst data from each device clogged things up.
• Related to error resilience is the tardiness of data transmission: latency. This of course is more important with video. Anyone reading this knows the issues: 20-100 milliseconds of latency, depending on the application, results in poor delivery of high-bandwidth video across an enterprise or across the country. So the need is obviously as little latency as possible.

Only after all that deconstruction did the engineers at Atlona explain how their new OmniStream solution addresses all those needs. But my take-away is that where their solution makes breakthroughs that we can most easily assess, at a demo at InfoComm say, is in the following:
• The Atlona OmniStream encoding/decoding can, according to the company, deliver 1080p, 60Hz, with only 9ms of latency, at 4:2:0. (UHD, 30Hz, with 18ms, but at 4:4:4). Atlona said that its new system for getting latency down to negligible levels is based on algorithms developed by the BBC for broadcast TV, over which it has layered its own technology that eliminates the need for frame buffers and so spends fewer frames to get the resulting full data-packages delivered to the customer’s porch.
• Atlona will intro also their Dante product for audio transmission over IP. Dante is part of OmniStream family. “We don’t want to do the audio DSP,” said David Shamir, “but just move the audio over IP to deal with latency.”
• Up to two channels per box, not just one. This is important for what it enables, but also for the cost savings of just needing one box.
• All of the above three, at an attractive price point.

You don’t have to take Atlona’s word for all that. You can see it in action at InfoComm in June, and bring your golden video eyes and your integrator’s tough questions. It should be well worth the visit.

This is the full press release from Atlona, just sent out today:



OmniStream AV over IP Product Family

OmniStream is an all-new AV-over-IP product family from Atlona for distributing 4K video, audio, and control over a standard gigabit network. It delivers the performance and dependability of traditional AV distribution with the added advantages of scalability, security, and cost efficiency associated with IP networks.

OmniStream was engineered from the ground up at Atlona and features several industry-exclusive capabilities, including:

•Redundant AV networks with independent data streams
•Secure content distribution
•High density encoding and decoding
•Enterprise-grade network error resilience

InfoComm 2016: The AV Over IP Show

The resounding echo from the AV punditry following InfoComm last year was about evolution versus revolution, and ultimately how that should be viewed positively, drowning out the naysayers that came looking for little else than the next earth-shattering gadget.
