AB512 7 msec Delay, Broadcast Quality, Wireless Video Link with 3 KM / 2 Miles range. Learn how the system works in this recorded webinar. https://www.vidovation.com/product/7-msec-delay-2-mile-range-broadcast-wireless-video-camera-mount-system-intercom-paint-camera-control-ab512/
Wireless video systems used to have quite a bit of latency, as much as 2-6 frames, causing all sorts of audio lip-sync and video delay issues. But now, the newest wireless video systems have just 7 milliseconds latency (much less than a frame!) and use industry-standard H.264 encoding – which means lip sync issues are solved and switching between various cameras and sources is seamless.
We've had a lot of questions about this new technology from "Just 7 milliseconds, is that for real?!" to "How can I solve the lip-sync issues we are dealing with at live events?" See how it works, ask your questions live, get a feel for the latest wireless camera systems and how they could help you. Learn about:

ABonAir’s AB512™ systems deliver video in an unexpected 7 msec delay without compromising ABonAir’s reputation for superior video quality. In addition to the 7mSec delay, the AB500™ product family includes a proven H.264 CODEC that was explicitly designed to reduce latency and increase picture quality in wireless video systems. The range increased to a fantastic 3 KM or 2 Miles by CODEC-Wireless optimization. The system features an automatic RF spectrum analyzer which automatically selects and hop to the best RF channel without dropping a single bit. The manual channel selection option is ideal for frequency coordination. Based on RF link conditions the system features Adaptive Modulation and Adaptive Bitrate.
AB512 – ABonAir Best Wireless Video Link
The most comprehensive, feature-rich solution with all upgrade option.
ABonAir’s AB512™ wireless video system enables camera teams to transmit video directly from cameras to media centers or OB trucks wirelessly. Built on a bi-directional radio channel between transmitter and receiver, ABonAir’s systems acknowledge the correct acceptance of each group of pixels, thus provides exceptionally robust and reliable transmission. The AB512™ supports ABonAir’s Fiber Coverage Extension (FCE), which enables connection of a single receiver to multiple FCEs in various venue locations (e.g. Horse Race Track – racetrack, stables and the winning circle) or even on completely separate sites (e.g. football stadium, basketball arena and swimming pool) all via fiber cables with unlimited range.

Until a few years ago, only large networks could use wireless equipment because it required purchasing expensive frequency licenses from the regulator. In recent years, however, governments and regulators around the world provide unlicensed frequencies for public use for any purpose – including video transmission – allowing even smaller productions to use wireless links easily and free of charge. To answer this demand, manufacturers started to develop unlicensed solutions. Unlicensed systems’ volume grew and drove cost down, motivating big networks also to use them even though they own frequencies.

Transcript:
Speaker 1: Good morning my name is Jim Jachetta I'm one of the co founders and CTO of VidOvation. VidOvation is a transmission contribution and distribution company. We help customers transport their video through the public Internet over bonded cellular, over wireless on the network, over fiber. We basically help folks move their their video content and it's usually live. Live is a common denominator with what we do. Today we're going to talk about some of the latest developments in wireless technology. One of the biggest pain points customers have when doing live video over a wireless transmission is having as low as possible latency as possible. So I'll give you an example if you're shooting video inside of a sports arena and you're wirelessly shooting the person singing the National Anthem, and you're going up on the big screen. Even if there's a frame of latency. A lot of systems have several frames of latency. But even a single frame of latency is noticeable on this on the big screen. And when the action on the field or the national anthem is being sang.
Speaker 1: There are systems that have low latency on the market. But these systems use very aggressive encoding and VidOvation offers systems like this. They're at a lower price point. But I don't consider them broadcast because they're not using sophisticated compression techniques. They're actually using aggressive encoding where bits are thrown out, rather aggressively, unintelligently. And there is a market for those types of products, maybe for video assist, where they're not so concerned about the quality, but they need to see the image with as little latency as possible.
Speaker 1: But what we're going to talk about today is broadcast application, broadcast quality and the system we're going to talk about today is the only broadcast quality system with latency this low, as low as seven milliseconds. So we're going to get into that today. Before we get started, though, let me ask you guys a question. Are any of you folks out there using a wireless system today? Is that something you're using? Just curious kind of where the audience is at in their pursuit of technology, et cetera. I can show you guys the results. It looks like it's pretty much 50/50 that's interesting. Oh, no, wait, it's changing. Wait, wait, here let me, I'll stop it, and then I'll share it. So you guys should be able to see, I'll just read it to you, 64% of you are using some sort of a wireless system right now. And 36% of you are not. So maybe you'll learn something new today, contrary into what you're using. We'd love to talk with you either way about your wireless needs.
Speaker 1: Let me jump in. Let's see. There we go. Again, the biggest, the number one attribute or the number one complaint or issue is this latency. And as I said before, our partner ABonAir is the only one that does a sub frame or less than a frame or seven milliseconds, which is quite extraordinary. Any kind of application, live application, sports, cinema drone, we're working on a couple of, you know, large larger type drone projects, and they'll be flying the drone with the image, with the camera image. And if there's even a smallest amount of latency they might crash the drone. Camera control if the video engineer is painting the image through the system. ABonAir has extremely low latency when it comes to painting the camera. The ABonAir system is designed from the ground up to support not only video but intercom and paint. There are different radios or different subsystems or a bunch of different subsystems combined to make the different functions.
Speaker 1: Some of our competitors will have a radio for the video, a radio for the intercom, a radio for the camera control. ABonAir is built from the ground up with a bidirectional radio to support everything and has up to 50 megabits per second throughput. But I'll get to some of these features. Again camera control I mentioned pulling focus. So if you're controlling a camera, the iris focusing the camera, if there's a tiny ... You'll be focusing an image from a few frames ago. So there'll be this lag which will drive your director crazy that the camera won't be shaded right. Or there will always be these lag, it'll appear as if the video engineer is asleep. Why is the video engineer always falling behind? And it's not really the video engineers fault, it's the wireless camera system, is delays in the radio.
Speaker 1: So all RF radios, all microwave radios have some sort of modulation scheme. So what does that mean? Well, in simple terms, if we send one bit through the system at a time, like high low, on off, on off, that would be a very rudimentary kind of AM type of transmission scheme. And we would be very limited in the bandwidth that we could use or the throughput that we would get. So in modulation schemes, there's techniques that will send more than one bit per symbol. Or as you can see here in the slide, QPSK, Quadrature Phase-shift Keying is actually two bits per symbol, or there's for actual states. You can see here to the right there's a diagram of that. So it's two bits 00, 01, 10, 11. So there's actually four states in a given word, or a given symbol. You could think of it as, like a data bus, in a computer.
Speaker 1: A rudimentary microwave system would have a one bit bus. So by doing some modulation techniques, Quadrature Phase-shift, or 16 QAM, higher order modulation, allows us to put more bits through so in hence we're making a wider bus. So in a given bandwidth, say we have an eight megabits bandwidth to deal
