Why did you decide to create a new platform for T&M?

There's a lot of talk about hybrid in the industry and we recognised early on that there were some big changes in the pipeline to do with SDI, IP, uncompressed and compressed signals and we had a lot of our own end users asking for something specific for UHDTV. The need for compliance testing to SMPTE standards for 4K was not addressed by anything in the market specific to broadcast so we looked to provide this much needed facility for manufacturers developing both 4K and 8K products. IP is also important so that too needed the technology to support it to provide a single instrument for T&M. Out of all this came the Qx - a radical new platform.

How long has the Qx been in development?

The reality is we have been working on it for over 2.5 years, a relatively short term for such a leap in technology and there have been significant challenges. The biggest decision was early on when we had to decide the key silicon suppliers, those who would deliver class leading product to meet our tight timescales. In addition with so many new UHDTV formats supported by SMPTE meant there are now over a thousand standards - excluding 24 and 48 Gbps payloads. Of course there is also the requirement for the Qx to be IP compliant and even here you have new developments it seems monthly with variants such as 2022-5,6,7, ASPEN, VSF TR03, AES67, TICO, AIMs- all formats the Qx is able to support as development continues. So the true answer is it is constantly in development and upgrades to the core software will be on going for at least the next 3-5 years as requirements evolve.

Can you tell us a little about the hardware?

The Qx is built on cutting edge technology. In essence the Qx has uniquely 4 separate 12 Gbps capable multi-rate inputs and outputs supporting payloads up to 48Gbps. It has over 30 GHz (5th harmonic of the 6GHz fundamental for 12G-SDI) analogue bandwidth on its front end making it the most powerful solution for T&M both now and going forward. It has 2 x SFP+ cages each supporting 12 Gbps optical or coaxial SDI and supporting 10 Gbps Ethernet for IP developments as the technology becomes available beyond the 'bleeding-edge'. We definitely needed the Qx to support both SDI and IP - a true hybrid solution, so the CPU combines technologies from both FPGA and a processor to enable such a flexible solution. It also has a clever client/server capability which we will be developing, but more on that later in the year.

What are the Qx's USPs?

The main USP of the Qx is its toolset in support of compliance testing. If you're a manufacturer working with UHDTV signals, particularly up to 12Gbps, then in theory you can't release a product unless it has been compliance tested. The SMPTE standards require the signal to be analysed with reference to the physical layer and here we have a show stopper. The eye and jitter technology on the Qx is such that it can support rise time, fall time, overshoot, undershoot, timing and alignment jitter due to its RTE technology. RTE stands for Real-Time-Eye which provides instantaneous presentation of the eye pattern with its associated automatic SMPTE compliance measurements. You need the technology present in the Qx for testing PCB layout, SDI driver design and driver pre- emphasis settings - key requirements for test before and during manufacturing. This is linked to PCB FR4 types, layout, correct register settings in the chipsets and quality of assembly. All this will have an effect on performance. We believe the Qx is the only product available other than a very expensive high bandwidth scope that can do this. It's also the reason we have such a large order book - there are no other contenders within the price range of the Qx and our manufacturing customers all need to do compliance testing!

I mentioned standards earlier and here too the Qx has some USP's. We have always been known for our GUI design making it easy to select standards under test. Our preset Sx range already supports over 300 however the need for the Qx to support standards that in some cases require 4 separate inputs has meant the interface has had to work a lot harder to 'un-complicate' this process. We have spent considerable time on the new design and the response at BVE 2016, the UK's main broadcast show, proved the elegance of the solution.

The Qx is also a combined generator and analyser solution -

a real must for closed loop testing and able to generate and analyse at the same time - a PHABRIX feature across all products. Crosstalk is usually the problem when developing products that do both functions however with the Qx we have developed a very low noise generator that works completely independently of the analysis circuitry so eliminating crosstalk.

What will you be showing at NAB?

The Qx will of course be centre stage. In fact visitors to our stand N4219 will be surprised to see we have two dedicated 'offices' on the stand to cope with the Qx interest. We also have a new software release for our Rx series and the Sx TAG hand held.

Interestingly more and more broadcasters are looking for cost effective solutions for test and measurement and of our products the Rx rack mount Rx2000, Rx1000 and Rx500 I am sure will be popular at the show. Quality control has come to the fore recently and in this application the Rx rack mount series offers a combination of both video and importantly audio toolsets in one single unit, basically making the whole process more affordable. At the show you will see new closed caption functionality and CC line detect. Loudness too has been enhanced so lots to see.

What about the future for the Qx?

The Qx has definitely been built with plenty of room for future development. One of the feature sets we will be adding shortly to the Qx is focused on stress testing SDI interfaces - arbitary waveform jitter insertion, eye amplitude control (800 mV +/- 10%) and jitter spectrum analysis. The platform is very versatile and we have been asked to include HDR and colour space toolsets for post. All I can say is watch this space. At NAB we will be looking to discuss the future development of the Qx with our customers.

How much does the Qx cost and when is it available?

Our sales director Martin Mulligan would be your best person to answer that question. Come and talk to us at NAB, we are more than happy to discuss and share pricing and availability information with you depending on your needs. The Qx is shipping in April.

KitPlus KitPlus recently took delivery of an interesting piece of equipment for review. We like our iPhone gadgets here. For us, useful iPhone gadgets started when the Olloclip lens gave us a wide angle adaptor. This was a good start, finally evolving into a proper tool when Ziess produced the Exolens system for the 5,6 & 7 series iPhones. Around the same time as the Olloclip came out we were testing the Fostex AR4i which was a very exciting development at the time. You have a portable device, that you carry everywhere with you, connected to the world but with very limited audio capabilities. A stereo interface with decent microphones was a real boon!

Meet the experts: Six steps for award winning sound design
Chris Turner Few can argue that great sound design is one of the most important elements to any moving picture. Mute most horrors, and the difference in fear factor will be enormous. Visualize Jaws or Star Wars, and John Williams’s iconic score will instantly come to mind.

TV Futures, Tales on Location
Georgia Thirtle If I think back to last May, I was just finishing my second year at the University of Portsmouth, studying Television and Broadcasting, and winding down for the summer. Then out of the blue I got a message from my course leader, saying I might be getting a call from someone who was a location manager working for Raider productions, you know, the production company behind the upcoming Tomb Raider film, I mean, what!?

VR and the importance of tracking
KitPlus I would like to begin this article by clarifying what we at Shotoku mean when we talk about VR in live production. It’s not the production of immersive, 360 content where you need to wear a headset; we are talking about virtual studio (VS) and augmented reality (AR) work, such as placing graphics into a green screen environment or physical set. The technology used for this work is entirely different, though equally specialist – therefore it is important to understand the challenges of this kind of production in order to make informed kit choices.

State of the Nation
Dick Hobbs - new

On the most recent occasion I was trimmed, my hairdresser had just returned from a holiday in Hawaii.

Where she thought she was going to die. She thought this because the state’s emergency alert system was triggered, sending messages across all available platforms, for 38 minutes, that a ballistic missile was about to strike. That, I suspect, is the sort of thing that casts a pall across your holiday.

Why did it happen? Essentially it happened because an operator selected the wrong menu item. “I feel very badly from what’s happened,” he is quoted as saying, in a somewhat mangled version of English which may at least in part explain his difficulties with menu items.

How IP-based KVM can improve workflow in broadcast control rooms

Out of the box: Sennheiser Ambeo VR microphone
Jon Pratchett 2 The use of 360 video, especially on platforms like Facebook and YouTube is really starting to take off.

Now players like Insta360 and even GoPro with their fusion 360 camera are providing single camera, high quality solutions, enabling the masses to put out reasonable quality, certainly watchable, 360 video.

2018: A Changing of the Guard
Peter Savage 2 The guys at KitPlus asked me if I could write about what I think is going to happen in 2018 – a feel, or mood, piece of what we might see this year. I’m not sure why they asked me but perhaps it’s because I’ve been around the industry a long time. Anyway, to look forward I think sometimes it’s best to look back as history has a habit of repeating itself.

TVFutures: Learning is the key
Abbie Neill If you asked me the question ‘where do you see yourself after you graduate’ three years ago I would have probably answered  ‘in a lot of debt, but if you don't think about it, it doesn't exist because three years is a long time right ?’. WRONG! These three years studying Television and Broadcasting at the University of Portsmouth have been the quickest three years of my life. Back when I started I didn't really have any idea what I wanted to specialise in and the dreaded four letter word AVID used to be my biggest enemy. However I persevered through the 3792871 hours of lectures learning how to use the software, how it functions, neither did I think I'd be a one woman match of the day by graduation'.

IP for everyone and 4k everywhere - that will be 2018
John Smith -new My first prediction for the coming year is that the use of IP to move broadcast content will increase dramatically.  Ultimately, it will become the commonplace, just as the use of IP has become part of our everyday, consumer lives.  Live sports are closely linked to this growth, as conversion of broadcast signals for transportation across established telecos networks enables content to be viewed in real-time, regardless if it’s in the next room or across the globe.

A new AEON in Wireless 4k
JP Delport Whatever production companies are doing right here, right now, today, with wireless HD production tools, they want to do right here, right now, today with 4K UHD. That’s great, but common wisdom would share a host of challenges around 4k UHD, not least, the fact that 4K UHD requires 8x the processing power to transmit, then demands additional horsepower (and bandwidth) to accommodate the data and controls, wireless or otherwise, and of course, when you ramp up processing power, you ramp up heat generation, which needs to be efficiently evacuated.

A Bluffers Guide to Batteries

Speed in a Changing Media Landscape
Mike Nash We are living in the video era - the staggering statistics on video growth make that abundantly clear. According to Cisco’s Visual Networking Index: Forecast and Methodology 2016–2021, video will make up 82 percent of all consumer internet traffic by 2021, an increase from 73 percent in 2016. To put this in perspective, “it would take an individual more than five million years to watch the amount of video that will be crossing global IP networks each month in 2021.”

IP will change the way that people interact with video, making it more flexible, more accessible, more scalable and will provide more opportunities for content delivery

The dangers of live streaming without a license
Joseph Adamson The entertainment industry is visual and sound driven. Without these two elements there would be no such a thing as entertainment. Its obvious that there are people who create sound/s and visuals. Copyright laws were created to protect the industry and these artists. Many organisations have been created to look after musician, writers, poets and filmmakers. For example there are a number of bodies especially the MCPS [Mechanical-Copyright Protection Society], which is responsible for collecting royalties and licensing of music on behalf of musicians and music producers.
