In the world of audio-visual systems, the design, installation, and troubleshooting of today's distributed AV setups are nothing short of a technological labyrinth. At the heart of this complexity stands HDMI® – the unsung hero of seamless AV experiences. HDMI, with its multitude of concurrent protocols, handles everything from system initialization and configuration to video transmission, audio exchange, and even the passage of essential metadata, enabling advanced features like High Dynamic Range (HDR).

Yet, for professional AV integrators and installers, mastering the intricate dance of HDMI can be akin to navigating a maze blindfolded. The lack of visibility into the inner workings of HDMI systems often leads to frustration, costly troubleshooting endeavors, and unforeseen project delays. However, there's a beacon of hope in the form of knowledge and processes that can illuminate the path forward.
​
In this article, we unveil the secrets that can transform the way AV professionals approach their craft. By delving into the nuances of HDMI technology and understanding how to verify its various functions, integrators gain newfound visibility. This newfound insight empowers them to create more predictable, robust AV systems, paving the way for smoother installations and improved performance. Most importantly, it dramatically reduces troubleshooting time, allowing installers to take their work to new heights of efficiency and effectiveness. Join us on a journey through the world of HDMI, and discover how it can be a game-changer for AV installers.

The Imaging Science Foundation (ISF) was created in 1994 as an effort to educate television sellers as well as consumers about video standards and adjustment methods that have come to be known as display calibration. In the formative years of color television and in many circumstances still true today, consumer sets were incapable of producing images considered accurate to knowledgeable, careful viewers. Circuit designs for televisions and the few video projectors present during this era lacked the controls necessary to make meaningful adjustments to the image that might result in a more lifelike image. The detail in dark shadows and in the brightest areas of today’s images, along with natural-looking colors including accurate skin tones were not the objective for commodity-priced televisions that dominated the days of promotional big-box retailers. Poor parts selection led to pictures that were often blurry and marketing departments turned to antics such as demanding the sharpness circuit be overly exaggerated to compensate for the inability to produce a well-defined picture. 

Meanwhile, in legendary film centers such as Hollywood and London, talented artists toiled feverishly, spending countless hours over the most minute details of a film or television production to accurately convey the director’s intentions. What looked fabulous on the sound stage was scarcely conveyed by the broadcast networks. Not even live-action sports closely resembled the actual event. Recognizing this disparity, the ISF embarked on dual missions. One was designed to assist TV and projector manufacturers to commit to producing products capable of delivering as accurate of an image as the prevailing technology was capable of. Advancing the technology and advocating for a change in standards were also included in the ambitions of the project. Second was to provide education to the Consumer Electronics industry on current standards, how to prepare as standards evolved, how to influence manufacturers into developing products to comply with the standards by refusing to sell models that failed to meet them, and ultimately, train a legion of specialists, called Calibrators, to properly adjust televisions and projectors to faithfully reproduce the incoming signal.

Those eager to attain this proficiency included installation personnel from Audio/Video installation companies, now known as “Integrators”, media professionals, interested enthusiasts who became calibrators, enthusiast magazine reviewers, and even engineers and key personnel from the television manufacturers themselves. AVPro Global, in conjunction with ISF President Joel Silver, conducts ISF seminars throughout the year around the globe. The seminars are often timed around industry tradeshows to make attendance easier with a dual-purpose trip. The major shows are ISE, InfoComm, and CEDIA. The ISF has partnered with CEDIA to provide education based on the standards established by the International Telecommunications Union (ITU) and the Society Of Motion Picture and Television Engineers (SMPTE) which are rigidly followed by the film and broadcasting industries and for which the calibrations methods are adapted in accordance with these industry standards. These educational opportunities are available through a combination of online and in-person seminars.
