Audio Return Channel (referred to from here as ARC), is the option to send audio from a Display upstream to an Audio Playback Device over a single HDMI cable. This can be done without an external source and audio-transmitted from a Display's internal apps. While ARC may support higher bandwidth audio signals than previously capable via Toslink and Analog transmissions, it cannot transmit uncompressed audio such as Dolby TrueHD. However, hope is not lost for the home theatre enthusiast with an older system as a format of DD+ Atmos can still be transmitted over ARC. Recent revisions to ARC have brought forth Enhanced Audio Return Channel (referred to from here as eARC). eARC allows for uncompressed High Bit Rate Audio Formats, such as Dolby Atmos and DTS:X, to be returned to Audio Playback devices bringing true cinema-grade audio into the home without all the external devices.
 The only issue with eARC? It may require you to buy a new cable. Bullet Train provides a variety of HDMI cables capable of supporting the high bandwidth of uncompressed audio, while supporting video beyond 4k. Still using ARC or Toslink? Bullet Train cables also support ARC. If the need arises to extend Toslink or ARC over distance, AVPro Edge offers solutions to extend either up to 330ft over category.
 This article is a part of a continuing year long series that highlights the people and experience of those that have worked closely with the Imaging Science Foundation for years. We have accomplished much over the years, and I have personally been recognized, awarded and written about for years - that is certainly not the whole story. The untold story is the years of hard work of many other ISF instructors who have made this possible. I have not done this alone, and it is time many of them have been given a voice. This is the first of a year long series where you will hear from some of the top calibrators working alongside ISF, we hope you enjoy. -ISF Founder, Joel Silver This month we will hear from our own Jason Dustal. 
As a young kid I was fascinated by electronics, especially Audio and Video products. My Great Grandfather owned a TV/radio repair business, and my other Grandfather and Father were both into early Hi-Fi and Home Theater. I basically grew up around this stuff which explains my love and passion for the industry.
I can remember my Grandparent’s TV from the late 70s/early 80s…a huge console TV with a record player under the top lid. On the front panel there were a few knobs that would alter the picture, and I was constantly getting into trouble for twisting them and annoying everyone who was trying to watch TV. Unknown to me at the time this would be what I would end up doing for a living! Fast forward about 15 years and I was working at a Florida based high end home electronics store, Sound Advice. One day one of my fellow co-workers brought in a DVD with some test patterns. He explained to me that by using this disc we could make the TVs “look better”. My young mind went into overdrive knowing that there was something that I could do to make it better, and this began my quest for the “perfect picture”. This was also the first time that I ever heard about the ISF. In 2008 I finally had the opportunity to attend an ISF class. The first class that I attended was hosted by the company that I worked for, so unfortunately I wasn’t able to meet Joel. We spoke on the phone a few times and I was constantly emailing him with problems that I was running into in the field. I irritated him enough that when we finally met, he knew me well. This was the beginning of a wonderful friendship and professional relationship. Since then I have assisted Joel in many classes, and in 2012 I started teaching on my own. Since then I have personally certified close to 1000 students. I would have never thought in a million years that I would be teaching alongside Joel, much less teaching the class myself. I have gone to places that I never thought I would get to see and I get to play with systems that I couldn’t afford in multiple lifetimes. I absolutely love my job and can’t imagine doing anything else!  Thinking about getting back into people’s homes to calibrate? This is one calibrator’s experience
I, like most calibrators, have taken a break from visiting people’s homes during the COVID 19 outbreak. The last home I visited was just before lockdown during the first weekend of March, and although I have received a lot of requests I have put them off. Now that new TV models have been hitting the streets the demand for the work is growing, and by taking some precautions I have a plan for myself and my clients going forward that will ensure everyone’s safety. This client originally emailed me about working on his TV, and before finalizing the appointment I was open with him and told him my concerns with working indoors in close quarters with someone. He understood and we came up with a checklist to ensure that everyone was safe and comfortable. It is always good to set expectations with your client about everything, so this may be something that you consider going forward. -No contact with client – This is a hard habit to break, but an important one. If you do shake hands or fist bump be sure to hand sanitize afterwards. -I brought my own remote (or wipe theirs down before touching ). A remote control can be a petri dish full of germs as everyone in the home has access to it. Remotes are often forgotten during cleaning, so bring your own (used remotes are easily found on eBay or in a drawer somewhere in the office). -Don’t touch anything that you don’t have to. There is no reason to unnecessarily expose yourself. Be cautious of leaning on walls, touching light switches, the TV stand, etc. if you do, remember to hand sanitize afterwards. -Shoes outside (or disposable booties) – I prefer disposable booties when entering any home. It shows that you respect the customer’s home, and the booties can protect you from any contaminants that might be on the floor. -Work in a clean area – Before I arrived this client swept, mopped, and disinfected the area that I would be working in. I didn’t ask for this, but I thanked him for the courtesy and thoughtfulness. -No sitting on the couch – Again, eliminate any unnecessary potential contamination. I typically stand for most of the calibration anyway, but if you like to sit you can always bring your own foldable or collapsible chair. -Clean hardware with alcohol wipes - After the calibration, before all of my gear goes back into its case, it gets a thorough wipe down. -Electronic payment – No physical cash means less potential for exposure -Email charts and receipts – Sometimes I will give my client a thumb drive with all of the performance charts and settings. Going forward it will all be electronic. There are several good, free file sharing services out there, and for simple things like this I like Google Drive. -Mask may be necessary – In some cases a mask be necessary for the comfort and safety of everyone involved. Masks vary so be sure to chose one that is both effective and as comfortable as possible. I personally have KN95 masks (N95 are also highly recommended but currently harder to find). -Bring your own water bottle – If you are like me and drink a lot of water I recommend bringing your own bottle. I have a large insulated bottle that keeps liquids cold (or hot) for several hours. Bringing your own bottle means less things you have to touch in case you are thirsty. -Find a clever way to remove outer clothing before coming home – My clothes went straight into the laundry when I got home just in case I had any hitchhiking germs -Shower right away – You have already taken plenty of precaution before and during the calibration, this is the final step in ensuring that you have done your part to protect yourself and anyone in your own home. I’ve spoken with a lot of calibrators and integrators who are hesitant to start visiting clients again (myself included), but by following these steps you can ensure the safety and comfortability of yourself, your client, and both yours and your client’s families. I hope this helps! Feel free to reach out with any questions or other suggestions! – jason@avproglobal.com Jason Dustal Training and Education AVPro Global CEDIA Collaborates with Imaging Science Foundation (ISF) to Offer Video Calibration Training6/9/2020  FISHERS, Ind. (June 9, 2020) – Today CEDIA announced a new training collaboration with the Imaging Science Foundation (ISF). This development aligns with CEDIA’s strategic mission to bolster industry education and standards and provides integrators with unparalleled access to ISF’s renowned video calibration curriculum and certification.
CEDIA has worked with ISF Founder and CEDIA Lifetime Achievement Award recipient Joel Silver to create a hybrid version of the ISF training which includes online modules as well as hands-on training. Level I of the ISF class is available now in the new CEDIA Academy online learning platform and includes eleven self-paced modules covering the fundamentals of color science, display standards, and detailed tutorials on the ISF CalMAN workflow calibration software. “CEDIA sees calibration as an essential practice – we teach basic video calibration techniques and encourage all members to follow the recommended practices. It is so important that CEDIA’s Awards program requires that all project entries in the home theater and media room categories include an audio and video calibration report. Calibration has a broad reach throughout the industry — CEDIA is actively working with our fellow association leaders on new standards that include audio and video calibration. All that to say, working with ISF to teach the industry’s most prestigious video calibration certification was a no-brainer,” said Ian Bryant, CEDIA Vice President, Technology Application and Workforce Initiatives. Level I serves as the prerequisite, and ISF Level II and Level III will be hosted as in-person, hands-on training classes with dates to be scheduled later this year. These higher levels will focus on the ISF software-guided solutions for advanced calibration and system parameters including: EDID/HDMI verification, 3D color management, multipoint color balance, and other recent innovations. Joel Silver adds “ I am incredibly proud of how the online modules have turned out — I’ve been told for years that the first day of the ISF training is always the most difficult. Transitioning that first day of content into self-paced online courses is going to serve the attendee well and ensure they have time to really set their foundation to get started in calibration.” “Having members of your team trained in calibration is a business opportunity for integrators — I took the training myself prior to joining the CEDIA team as a way to set my company apart. Many companies underestimate the power that calibration plays in both the equipment performance and the overall customer experience. When the client sees the before and after documentation and quality of the image, they will have more faith in the fact that you have their best interest in mind, and that trust can open up additional sales not only to your client but also in the form of referrals,” said Bryant. This spring CEDIA hosted a webinar on The Business of Calibration presented by Joel Silver and Gerry Lemay for integrators looking to understand how calibration can drive revenue for their businesses. The ISF Level I modules are available online now in the CEDIA Academy; training dates for Level II and Level III will be announced in the next few months. CEDIA members enjoy preferred pricing on all training. To learn more about the ISF training at CEDIA, visit cediaacademy.net.

When someone can show me another way to see the same thing differently, better, count me in. I'm into that moment of discovery and inviting others in. Hence, my history with ISF! We provide references for you to re-view your preferences So, whether it's seeing white buttons appear on a white shirt or dark figures emerge out of a dark background (Game Of Thrones - The Long Night) or to see that everyone has the right skin tone, the joy of discovery that we provide as instructors and calibrators is priceless in its sharing TV and movie watching are shared experiences. If a tailor can make your "off the rack" suit look better on your body An ISF calibrator can tailor your "out of the box" TV to look better in your room -Robert Fucci, Director OF ISF Calibrator Testing & Certification  For over 20 years, Robert Zohn (Value Electronics - 35 Popham Rd, Scarsdale NY) has been at the forefront of audio video sales. Every year this is celebrated with the wildly anticipated “TV Shootout”. In this face-off, all major tv brands are set up and judged by a select panel of display technology experts, and only one tv gets the winner’s title. For the next year, arguments are had by cinephiles and home theater enthusiasts on why “OLED will never lose” and how they can’t believe Panasonic won’t release models stateside. Well, this June is a little different, and while the TV Shootout has been postponed, our own Jason Dustal is going to talk with Robert virtually about all the latest and greatest TV technology. We want to give everyone the chance to join Robert and Jason so please register today.

We have accomplished much over the years, and I have personally been recognized, awarded and written about for years - that is certainly not the whole story. The untold story is the years of hard work of many other ISF instructors who have made this possible. I have not done this alone, and it is time many of them have been given a voice. This is the first of a year long series where you will here from some of the top calibrators working alongside ISF, we hope you enjoy. -ISF Founder, Joel Silver This month we will hear from Michael Hamilton... My fondest memory - endearing and everlasting in the ISF's now second decade - continues to be Joel's tireless commitment and personal access to attendees during seminars. His unique charisma never fails to bring people, literally from all over the world, to form a collegial camaraderie during the now three days of classes. Whether prior to a session starting, during a break or at the conclusion of the day, I've never failed to see Joel seek out someone to clarify a point, show something supplemental as an aside to the course topics, or simply allow someone to interpersonally engage him. From my first seminar as an attendee in 1995 at Lansing, MI through my most recent in Anaheim this past November, I am constantly in awe at how selflessly Joel devotes himself the ISF experience. Undoubtedly he has contributed to making my life rewarding beyond my dreams in an industry I love, as well as becoming a deeply treasured friend. And I would be remiss to not mention Jeff Murray's countless time, toiling often behind the scenes, which has richly contributed to the ISF throughout the decades. I hold dearly in my heart, a trove of decades-long memories and experiences we've shared. I am truly blessed. Michael Hamilton  Hunting down HDMI issues just got a lot easier with this handheld or rack-mountable test monitor from Murideo. Sioux Falls, S.D. - Murideo, an AVPro Global Holdings company, is excited to announce a new product, the MUR-MON-SING, an 18Gbps 4K HDR HDMI input field test monitor with analyzer functions. The product features a seven-inch full HD playback screen, EDID management, a built-in signal analyzer, HDCP 2.3 support, battery adaptor, and more. Murideo’s 4K test monitor is a compact device that comes with a battery adapter for working around a job site, but also fits perfectly in a rack with an HDMI loop out port that will pass along any 4K signal. This monitor also offers signal analyzer information such as resolution, color space, HDCP, HDR confidence, and audio type analysis. The ability to view HDMI signals up to 18Gbps (4096x2160P60 4:4:4) allows integrators to use this monitor with every consumer source on the market. As a part of the Murideo testing and troubleshooting family, the standards for this product are of the highest in the industry. Matt Murray, CTO of AVPro Global, stated, “The MU-MON-SING was brought to market by the overwhelming requests of field installers. I would say it was designed by installers based on their feedback and requests. It combines field portability in a lightweight yet large (7 inch) screen with some basic analysis function, including incoming signal information like resolution, frame rate, chroma sub-sampling, HDR, and more! It should become a common tool for field installers to have on the trucks.” For more information or to purchase MUR-MON-SING, please contact Murideo at 605-330-8491 or visit www.Murideo.com. About Murideo Murideo, an AVPro Global Holdings brand, was created to satisfy the need for modern testing tools in the custom A/V market.

Traditional category runs are cheap, easy to use, and can provide Power over Ethernet (PoE) up to 100 Watts. While copper has always been reliable cabling, it suffers from signal interference as well as length and bandwidth limitations. To keep things short, 4K and 8K video signals carry massive amounts of bandwidth, and copper can only carry these signals short distances, even heavily compressed. Now, more than ever, it makes sense to run fiber alongside traditional category runs. Fear not! Many advancements in fiber production technology have made fiber optic cable safer, more resilient, and more cost-effective. Although currently unable to carry power, fiber optics don’t suffer from EMI or RFI signal interference. Running duplex OM3, allows for 40Gbps Video Signal and 100Gigbit Ethernet up to 100 meters. Traditional 10.2Gbps Video Signals and 10Gigabit Ethernet can be extended further at over 300 meters.  In this battle of infrastructure, both is better. Fiber optics help future proof the install for years to come while category cabling can be repurposed for other uses such as lower network signals and PoE solutions. Mastering running both can reduce truck rolls, simplify upgrades, and increase overall job revenue.  This Tech Tip is brought to you by Sam Metiver.

With the introduction of the first practical projectors and the laser disc, my career with AV installation started. I learned the hard job of installing a CRT projector. Not only the convergence, but also the colors and more give me a headache sometimes. At InfoComm 2001, I learned Mark Hunter's colorfacts system and I was thrilled. This was the first tool in my eyes for better color, not only the test pattern. In 2006 I got my first contact to ISF by a Belgian instructor. In a closer cooperation with a former German instructor, I learned more and more about calibration and used this for my own dealer training also. In Amsterdam in 2008 I met Joel Silver. He was running an ISF class. What a big difference. I got flashed. Here, I learned so much about calibration, which I could use successfully in my dealer training. Since this time Joel and I always meet in Amsterdam or other places in Europe. Either helping him to run the ISF class in Amsterdam or running over the show. Also working together with AVPro team members Jeff, Matt and Loel. In this time, a family of AV enthusiasts was built up and is still working today.  In those days, I was working for a well known European projector supplier and doing training in Europe, Russia, China, and South Asia. Over this whole time I had been in contact with Joel discussing some bigger projects like laser projectors and more. When I left the projector supplier in October 2012 Joel appointed me as an ISF instructor. Wow, I was so so proud about this honor. Now, beneath my normal work, I'm doing ISF training with focus in the German speaking area. Here I'm working together also with Roland Seibt (test chief of the biggest German magazine in the area, Video), a well known specialist on HDR. Working together with bigger suppliers like LG, Samsung or Optoma and broadcasters is a smart advantage and allows us to stay updated on new technology. And last but not least always being in contact with Joel and the team of AVPro, discussing the latest development and trends. Best regards, Hartmut   The Murideo SIX G and SIX A Field Test Suite I first became aware of Murideo products during an ISF Level II Training class several years ago. That was where I was first introduced to the Murideo SIX G Signal/Pattern Generator - and its companion - the Murideo SIX A Signal Analyzer. I quickly learned that if I wanted to calibrate a display device accurately and efficiently or effectively troubleshoot a problematic 18Gbps connection chain, the Murideo SIX G and SIX A tandem was the preeminent and indispensable tools to have on hand. To this day, I still use both regularly for performing a variety of test-and-measurement procedures, including signal integrity/verification, troubleshooting - and of course - display calibration. However, I recently started using a new and extraordinarily powerful test-and-measurement tool; and as the saying goes: “There’s a new sheriff in town.”  The Murideo SEVEN Generator Working closely and in conjunction with major format originators, A/V manufacturers, and standards associations - the SEVEN Generator represents the culmination of intense R&D and unparalleled design excellence. The SEVEN is a formidable, quantum-leap behemoth that packs an amazing array of tools and capabilities. These tools and features warp the SEVEN G into an entirely new universe of A/V Test and Measurement. It literally creates a new market category, and it accomplishes it all without breaking the bank, your bank. The SEVEN Generator is the A/V Test & Measurement Appliance that everyone has been clamoring for, so let’s take a closer look. Below is just a sample of the tools and tests available. ALL IN ONE BOX!

 The Murideo SEVEN G is truly GROUNDBREAKING. Whether you are an A/V equipment manufacturer, an OEM, an electrical engineer, a professional calibrator, or an integrator/installer/dealer, you will discover a plethora of features and functions that will:
Finally, the SEVEN G is designed to be FUTURE RESISTANT (it already supports HDMI 2.1 standards and requirements), and it’s not stopping there. This marvel will ultimately play a key role in creating a better future for the A/V industry with vastly improved and more capable and stable products rolling off the assembly line. I hope you will take a closer look at this impressive and powerful A/V Test & Measurement machine and pick one up for yourself! For more in-depth information regarding the capabilities for the SEVEN G, please download the User Manual at www.murideo.com/SEVEN-G. This product review was submitted by industry veteran John Tumbleson. Learn more about John's experience in A/V and what drives his enthusiasm for the industry below.  Before starting my career in the high-tech industry; i.e. Apple, Iomega, Claris etc., I worked in the high-end audio industry where I manufactured my own private label speakers and studio monitors. This was the early to mid 70’s, and I subsequently became involved in the design and installation of discotheques at various restaurants and bars all over the country. A seminal moment for me came in the early 80’s when Sony introduced the Beta HiFi VCR system; and the world of video began to merge with the world of high-end audio. This became the genesis of what we now call “Home Theater” and at that point, I became bitten by the Home Theater “bug”. For many years Home Theater was a “hobby” for me, as my career at Apple and other companies was basically my day job. Then in 2012, I started on a new career path which incorporated A/V system control with residential and commercial projects, but I also became heavily involved with audio and video distribution and calibration. In 2014, while designing a commercial control project, I was introduced to AVPro. At that point - as it is said, our paths crossed, and a few years later, I officially joined AVPro. And as they say: “The rest is history”. My hobby is now my day job. But, I doesn’t really feel like a job, because it’s just too much fun!
Tech Tips are written directly by the Murideo's Tech Support Team. With years of experience seeing every HDMI signal available and working with hundreds of different products, the support team picks up helpful knowledge talking to Integrators, calibrators and electronics manufacturers around the world. This series is aimed to share that knowledge. Here is this month tech tip:
Uncompressed Video distribution can be hard; Passive Copper HDMI cables falter with distance and HDMI extension methods suffer from bandwidth limitations. The Answer? Active Optical Cables of course! What are Active Optical Cables (AOC)? AOC HDMI Cables are uncompressed HDMI Cables capable of running 100 Meters due to 4 Strands of Fiber over the TMDS Lanes which carry Audio and Video signals. BUT not all AOC cables are made the same, just like anything some manufactures will take short cuts in the engineering and development areas. Many AOC cables require external power or worse, use Plastic Optical Fiber used in TosLink cables, a known poor quality fiber type not ready for high bandwidth signaling. These lower quality products will take up space with extra power supplies and often are unable to reach 18Gbps bandwidths, which is need for HDR and high frame rate video. The Solution! The Bullet Train 10K AOC HDMI Ultra High Speed Cable is capable of uncompressed 48Gbps signaling and requires no external power supply. Bullet Train 10K AOC cables use Cleerline SSF OM2 Glass Fiber, and high quality fiber that is safe to terminate in the field. This means if we ever move past HDMI as a delivery method you can always cut off the heads of the cable and easily terminate the 4 individual fiber runs located inside the cable shielding. Not only future proofing your runs but allowing them to serve multiple distribution purposes.

When asked to write up my experiences and memories with ISF, two things came up, one humorous and then something I consider very important, let’s explore both. First Humorous During the very first ISF class I gave in Paris back in 2006, one of my journalist friends noticed that I often wear black clothes. Now this has nothing to do with the fact that Joel always wears black clothes as well. I have always been this way since I was a teenager. I replied that day and still do ever since that it is a very convenient way to ensure a good contrast ratio and black level for the systems I am dealing with. No interferences. It is also a way to advocate dark environment to improve the viewing experience.
Now Important
In 2008, I managed to secure an actual movie theater like screening room for the class since I happened to calibrate it in a regular basis. While it might have seemed overkill given the number of attendees, it gave quite an impression with an added bonus of a guided tour of the facility. Nowadays, my class are hosted at the French Sony facilities witch gives me access to professional products in addition to the consumer ones. It has been a great satisfaction and privilege to be able to give a glimpse of the movie making process to people typically associated with the other end of the spectrum, namely the residential AV installers. As the years came by, I also had the opportunity to train tech guys from post production facilities and even movie theater projectionists. The next class shall bring those different kind of people together for the benefit of everyone through exchange of views and experiences. You are able to sign up for my next class today, here are the details, and don’t hesitate to contact me with any questions you might have: Paris France Hosted by Sony France 07/06/2020 –07/08/2020 9am-6pm Julien Berry Website - http://hdvc.fr/ Email - info@hdvc.fr
Metadata - A set of data that describes and gives information about other data How could that little word (metadata) cause havoc for so many Audio/Video manufactures and integrators trying to line up the audio and video signal? Why? Because our industry has gone beyond traditional 2 channel, or 6 channel, or even 8 channels of audio. Dolby Atmos and DTS HD are perfect examples of audio signals that rely on metadata to distribute audio to through many channels. There is this invisible code running along side the audio signal that tells your audio products to distribute the specific sound to a specific channel; this code is metadata. Why would metadata cause lip sync issues? When dealing with metadata it takes time to decode the signal, this can cause delays in your audio delivery. You may find your audio signal is coming in after your video. This is a new problem as integrators have always had the opposite problem, audio coming before the video and needing to delay the audio to line it up. How many of the tools you use to line up that audio have a video delay option? Almost none! Testing your products to see how they react with different types of audio and video combinations will allow you to deliver a superior installation or product to your customer. The Murideo method allows you to test these signals via HDMI, ARC or even the HDMI 2.1 specification feature eARC.
The Murideo SEVEN Generator is a scientifically accurate audio video testing device that allows you to select thousands of combinations of audio video signals including Dolby Atmos audio and HDR resolutions. As you test your product with various signals you can measure the lip sync down to the millisecond. Allowing you to make adjustments as needed. If you would like more information on the SEVEN Generator give us a call at 605-274-6055 or email us a info@murideo.com. Product Webage for SEVEN Generator By Jason Dustal The first AVPro Academy class of 2020 is officially in the books! Thanks to Andy Spolar at the AWA reps showroom in Chicago, IL where we not only host the class, but also have our brand new AVPro Edge Experience Center. The AVPro Edge Experience center is a great place to visit to see live demos of AVPro Edge and Murideo products such as the Multi-Viewer, the 16x16 matrix switch, extenders, Murideo HDMI test equipment, and more. If you are in the area feel free to stop by and meet Andy. He can give you a live demo of AVPro Edge products and discuss with you about what AVPro can do for you and your customers. AVPro Academy consists of 2 days day of learning the fundamentals of Audio and Video in residential and commercial environments. During day 1 we cover everything from system design to troubleshooting. We dissect HDMI and learn how to troubleshoot small to large distributed A/V systems. Day 2 is all about display calibration and learning the core fundamentals on how to make a display look it’s best. My favorite part of AVPro Academy is always the hands-on activities. The students in this class learned how to use the Murideo tools to test the bandwidth on various HDMI cables, test devices for HDCP compliance, read and emulate EDID, and some valuable troubleshooting skills. Steve from Cleerline stopped by and gave a great demo on fiber optics. The class learned about the great benefits of using fiber as the A/V backbone, and by the end of the class some of the students themselves were terminating fiber in less than a minute. For the rest of the hands on activities we had some great tools and displays to practice with, including LG and Sony OLEDs, a Sony Z9 LED/LCD, JVC projector, a 2x2 video wall, and light meters from Xrite, Klein, Portrait Displays, and Jeti, and of course AVPro Edge distribution and Murideo HDMI testing products. This particular AVPro Academy class had a wide variety of students…some who were brand new to the A/V industry, and some with as much as 30 years experience. We even had a Home Theater enthusiast who wanted to learn about calibrating his displays at his own home. It is not uncommon to meet students in class with all kinds of different backgrounds. Broadcasters, manufacturers, post production, colorists, writers, and TV reviewers are just some examples. Most of the students stayed for the second day to learn about display calibration. This is a service very near and dear to my heart as I am a videophile who is always chasing the perfect picture. Learning this skill as an integrator is valuable and can set you apart from your competitors. Consumers want to maximize the potential of their system, and learning this skill will help with that. Integrators use the skills they learn to sell better systems and to maximize customer service, which in turn maximizes profits. Everyone who attends day 2 of class gets to learn the basics of ISF calibration, including an introduction to different display technologies, hands on with the tools that are used for calibration, and a temporary CalMAN license so they can go home and practice calibrating. Everyone who attends class and takes the ISF Level 1 exam earns a certificate and is listed on the ISF website as a certified dealer (imagingscience.com/dealers). CEDIA and AVIXA members are also awarded CEUs for attending AVPro Academy. One class down and several more to go in 2020!

 Joel Silver - ISF Founder, accepting the Lifetime Achievement Award from CEDIA in 2018 I started the ISF with a simple but radical idea at the time. I wanted to build a network of professionals that would adjust home TVs to accurately display the intent of creative artists and film directors. The initial focus was high-end residential integrators. Our success in that market was the result of meeting business owners with wonderful relationships with affluent clients. They were driven to install systems that would sound better and look better than anything their clients had ever seen before. We met most early ISF dealers through CEDIA and found many like-minded supporters there. Their clients saw vastly superior TV pictures and had the ability to afford them, and we were launched. We soon discovered volumes of manufacturer’s technical staff that understood what we were doing and would support our efforts. With them we were able to design TVs that could be easily calibrated in the field. That brought ISF features to millions of mainstream TVs. I never thought that could be possible for a radical idea. Studios were using consumer TVs as “client monitors”, and I soon found volumes of content creation professionals becoming ISF calibrators. That brought the concept full circle. There are now many thousands of professionals whose everyday work is faithful to the intent of artists and directors. -Joel Silver, Founder of the Imaging Science Foundation  If you want to be a consumer electronics professional, where is your sphere of influence? Let’s explore the entire process. You will see where you fit in and how critical to the industry your role has become. The entire artistic process is a series of optical and electronic “Transfer Functions”. Think of a digital signal coming into your TV, and then light comes out. That’s one kind of transfer function. Let’s follow the steps that deliver the intent of the director to viewers.
 We have accomplished much over the years, and I have personally been recognized, awarded and written about for years - that is certainly not the whole story. The untold story is the years of hard work of many other ISF instructors who have made this possible. I have not done this alone, and it is time many of them have been given a voice. This is the first of a year long series where you will here from some of the top calibrators working alongside ISF, we hope you enjoy. This month we will hear from Kevin Miller...   Kevin Miller - ISFTV I was involved in the creation of the ISF with Joel Silver dating back to the spring of 1993 when working at The Perfect Vision as the Publisher and CEO. The idea that Joel so eloquently described was spawned over cocktails one evening at an InfoComm show in New Orleans. A little over a year later, in February of 1994, Joel launched his company with the first ever ISF seminar at the Waldorf Astoria hotel in New York City. I was at that seminar as a student with my Philips color analyzer in hand.
I started my company, ISFTV, in February of 2001. Later that year, I co-instructed a seminar with Joel that followed the CEDIA show in Indianapolis. Day two of the seminar, as fate would have it, was on 9/11/2001. We had a very large group of nearly 60 students who were all quite shaken by the morning’s events. Our great friend Stu Kobak, who ran a DVD review web site of his own called Filmsondisc.com, got Joel on the phone and encouraged him to have us finish that seminar even in the face of the horrific events of that day. We did persevere and got the class to the finish line. Following that 2001 seminar, I spent many years co-instructing ISF seminars with Joel all over North America, which was a great learning experience. Joel helped launch my company as he has done for many small businesses all over the world. I am proud to have been a part of the creation of the Imaging Science Foundation, and continue to work closely with Joel and a number of talented technicians all over the country, furthering the goal of delivering the artist’s (Director’s) intent to consumer’s television screens. I have also been heavily involved for many years on the professional side of our industry, now supporting over 60 Post Production facilities with my professional calibration services and technical consulting in the New York Tri-state area. I have also been providing technical and product development consulting to TV and video source manufacturers since 2003. Kevin Miller ISFTV Email: kevin@isftv.com Web site: www.isftv.com They say a craftsman is only as good as his tools, and that couldn't be more true when it comes to calibrating displays. The whole point of calibrating a display is to test it against a known standard with extreme precision and accuracy. In some cases (such as post-production) an inaccurate display can disrupt the workflow of the project. This ultimately costs time, money, and frustration amongst the people who are doing everything they can to finish the project on time.
 Today there are hundreds and hundreds of test patterns available to set up and calibrate displays. The SEVEN Generator is packed full of test patterns from the best in the business. We included patterns from ISF, Digital Video Solutions, the Professional Video Alliance, Spears and Munsil, Bill Wetzel, and some of our own Murideo patterns as well. You will never run out of test patterns with the SEVEN! If you have custom test patterns, reference images, or videos that you like to use, feel free to upload custom material with our Uploader Software.
 Lip sync errors are painfully apparent in any A/V system. These issues have plagued integrators and calibrators for years, and until now, there has not been a calibration tool that allows you to measure lip sync. Now with the SEVEN Generator, you can not only calibrate the audio and the video but also easily measure for lip sync. These issues are hard to track down and are notorious for causing troubleshooting calls and truck rolls. Adding lip sync testing to your calibration ensures these issues don't show up after you leave the job site, and puts you ahead of your competitors.  HFR (High Frame Rate) is right around the corner and will make video look smoother than we've ever seen before. Sports fans and gamers are very excited about this, and calibrators need to be able to set the display up correctly for this new, highly anticipated feature. The SEVEN comes stock with native 120fps video material, which makes testing for HFR a breeze. HFR, along with other features, is part of the brand new HDMI 2.1 spec. There is a lot of talk about HDMI 2.1 right now, and we are seeing products coming with these new high bandwidth connections. Not only does bandwidth increase to 48Gbps with HDMI 2.1, but it also comes with some pretty cool features like eARC. eARC provides much more bandwidth for audio to travel from a display back to an audio source such as an AVR or soundbar. This will allow for fully uncompressed audio, including Dolby Atmos, over the eARC channel which is something the industry has not seen before. As a calibrator, it will be essential to test for these signals to ensure that your customer is getting the highest possible quality audio signal for their system. Easily use the Seven Generator to test for these signals and configure the audio in your customer's system the best way possible.  Speaking of HDMI 2.1, the SEVEN was built with this new standard in mind. It will come stock with an HDMI 2.0 output, and once available, you will be able to send in your unit and Murideo can upgrade it to HDMI 2.1. Again, something that's the first of its kind and only available from Murideo. This generator is packed full of features that will make a calibrator's life much easier. This highly advanced tool will ensure that your jobs are completed efficiently and at the highest possible level of quality. Increase customer satisfaction and outshine your competition!

Integrators have been hanging flat panel TVs and installing projectors for decades, but how many of those are calibrated? There is no doubt that every year TVs and projectors get better and better, and with HDMI 2.1 already here, we are about to see some truly unbelievable images. As great as these displays are, we are (and will always be) dealing with the same old dilemma: the display manufacturers have no idea what type of room the display will be in. They also can't predict every lighting condition, seating positions, what type of content the customer will be watching, nor what other gear may be in the system.  So, how do you ensure that the picture quality is optimized for each and every one of your clients? The answer is calibration. Calibration is a 100% custom service based on the client's unique environment and situation. No two rooms, systems, or people are the same, so why treat them as such? As I travel around and teach people about displays and calibration, I have been bringing up the infamous Game of Thrones episode that was "too dark" (read my take on the episode here). Every time the topic comes up, everyone in the room winces and has a nice chuckle about the amount of controversy this caused. Multiple integrators have told me that their customers were calling in, claiming that their new TV was broken! Here is my question: if the display the customer was watching had been calibrated, would there have even been a controversy? Or phone calls? Or truck rolls?  I have a personal client of mine who was unfortunately going through chemotherapy treatments. Her vision was severely sensitive and any bright light gave her a massive migraine. As a film buff, watching movies is one of her favorite hobbies, but because her TV was so bright she could not enjoy her favorite pastime. As a last-ditch effort before returning the TV to the retailer, she hired me to come over and check things out. During the calibration, we looked the test patterns together so I could tune the TV to her room and her vision. Two hours later, she was hugging me and crying because she could finally enjoy her movies without the migraines. Since then, she has referred me to at least five new clients. I love sharing this story because it really shows how important it is to understand not only a display's capabilities, but also the level of customer service you can potentially provide to your clients. These days most displays are pretty easy to calibrate. Just a few basic adjustments to a display can make a major difference in picture quality. Now that we have Autocal with CalMAN (a calibration software package by Portrait Displays), a full calibration can be done quickly and accurately. If you consider yourself a custom integrator, this a great way to separate yourself from your competitors!  My challenge to you is to find out if your competition offers calibration. Visit imagingscience.com/dealers, enter your city and see what is happening around you. You might be surprised by what you find. I recently hosted a webinar on this topic and had the founder of the ISF Joel Silver, HDTVTest's Vincent Teoh, and Portrait Displays Tyler Pruitt as guests. We had a great discussion about the industry and what we are excited to see over the next few years. Feel free to check that out here.  We host AVPro Academy and ISF courses all over the world several times throughout the year. Here you can learn more, in great detail, about this custom service and what you need to get started. If you have been before, but it has been a few years, maybe it's time for a refresher. Check out the dates and locations for these classes here.
If you are not calibrating the TVs and projectors that you install, I'd be interested in hearing why. What is holding you back? Written by Jason Dustal, AVPro Head of Training and Education  Today’s digital age has resulted in a greater need for homeowners, bars, airports, and sports arenas to distribute audio and video over long distances. Previously, coax cable was used to transmit these analog signals but, as resolution has increased, so has bandwidth. This created a need for infrastructures that can distribute higher bandwidth digital signals over a long distance. The use of Category cable and the introduction of HDBaseT came to the rescue. Using CAT cable, we can extend HDMI signals over 10x the distance of HDMI’s 10-meter specification. However, HDBaseT doesn’t use a traditional digital signal to transmit audio and video. While connection speeds for networks are measured in Mbps (Digital measurement of bits), HDBaseT signals are measured in MHz (Analog measurement of waveforms).  So, what does this mean?
Traditional ways of testing CAT cable using category testers does not determine whether or not the CAT cable can handle an HDBaseT signal. Most testing equipment made for category cables will check that the pinouts match on both ends of the cable, and sometimes the distance; more expensive units can even test for network speeds. Unfortunately, even if they can test data rates, it’s done in Mbps, and HDBaseT is measured in MHz. This renders the device inadequate for audio/video signals. While both can fall victim to EMI and attenuation from length, HDBaseT signals are more susceptible to both. So, how do I test HDBaseT signals? While there are a few solutions that test CAT cable for HDBaseT signals, they are expensive and few and far between. Don’t worry, hope is not lost. Tests can be run using a few simple tools you may already have:
Together these tools are only a proving ground for category and better results can be achieved by following both the HDBaseT Gold Standard and the HDBaseT Do’s and Don’ts. Checking category runs prevents frustration during installation and helps prevent additional truck rolls costing you money. So you want HDR, but it's not displaying on your TV or Projector? This guide will walk you though troubleshooting this issue.
One of the most common issues that integrators have today is not being able to trigger HDR on a display. This can be frustrating, especially when it seems like all of the stars are aligned and everything in the system is HDR capable. Here are some tips on system setup and troubleshooting that will help you in case you run into this issue. In the following scenario we are looking at this system: UHD Blu-ray Player --> AVPro Edge Matrix Switch --> AVR --> Display Some tips before you start troubleshooting:
How to troubleshoot for "No HDR": NOTE: Conduct these troubleshooting tests with either the Murideo SIX A and G or the Fox & Hound Kit. This guide is written for the SIX A & G Test Suite, but the process is almost exactly the same with the Fox & Hound Kit. Always have a known good 18Gbps HDMI cable in your kit. You will use this for testing different components in the system. Testing the source:
Testing the matrix switch:
If the source is outputting an HDR signal, the HDMI cable connecting the blu-ray player to the matrix switch tests out, and the matrix switch’s EDID is correct, then the problem should be solved. If not, confirm that the HDMI cable that connects the matrix switch to the AVR is passing 18Gbps. If it is not, replace the cable. If the cable tests out and shows zero errors, it’s time to move to the next component downstream. In this case that would be the AVR. Testing the AVR: Since the AVR has an input and an output you will have to test both.
At this point you have tested every other component and every HDMI cable in the system. If you are still not able to get HDR to the TV, follow these steps to test it:
In some cases, you may be dealing with an HDBaseT Matrix Switch. Here are some tips from HDBaseT that will endure a successful installation:
There are many ways to troubleshoot a system, and with the proper tools and methodology you can track down problems in a minimal amount of time. Come up with a plan, take things one step at a time, keep track of what you have and haven’t tested, and if problems continue to persist you can always call our tech support department at 877-886-5112 or +1 605 274 6055 (Int'l).
 For years televisions have been plug-and-play. From the introduction of color television, to component, to the early years of HDMI, everything just worked. Today, we live in a world of catching up. Our legacy set top boxes struggle to produce 4K while advanced 4K displays sometimes resist the change to new formats. But hope is not lost, understanding common issues in today’s mixed resolution world can decrease the amount of time spent troubleshooting.  Bullet Train 18Gbps HDMI Cables with Ethernet 4K and HDR have taken the world by storm. Next-Gen gaming consoles and premium streaming devices have made this possible within the home but not all displays are as accepting as others. You may find a host of problems while simply trying to connect your device. Problem:
 Distributed systems are a perfect way to deliver all sources to any part of the home; but what about HDR sources on legacy displays that do not support it? While scaling to the resolution of the display may show picture, you might find an issue with the image displayed. Problem:
 Dolby Vision is the cream of the crop in terms of HDR. The ability to adjust brightness levels frame by frame attracts many consumers to buy displays capable of doing it. Unfortunately, not everyone can agree on how to process Dolby Vision leaving us with different profiles used in the market. If the source plugs directly into the display, this is not an issue. However, in a distributed system with multiple displays capable of Dolby Vision, they might not be processing it the same.
Problem:
As displays continue to move from 4K to 8K and beyond it is almost guaranteed that new issues will arise. Being able to diagnose these problems now will help your ability to address them in the future.
