General A/V Articles & White Papers
Understanding Cables in the AV Industry In today's AV industry, source signal rates are continuing to increase as the ceiling is being raised by the display manufacturer's ability to faithfully reproduce higher and higher computer resolutions. It is not uncommon to see laptop presentations shown at 1024 x 768, not to mention the workstation-based presentations that reach even higher resolutions. What does all of this mean?...  Read moreCables: The Missing Link By Steve Somers, Vice President of Engineering In designing a system every product is carefully selected and has as much importance as another. Being caught up in all this, there is one important product that is sometimes overlooked. While you think about that, let's take a look at some of the important factors in putting an RGB system together. How will the product interact with the system? Is the bandwidth specification suitable, and does the product have universality?....Read moreSelecting the Right Cable Selecting the right cable for an A/V application, from the many different types available, can be a daunting task. Fortunately, although cable varies greatly in size, performance, quality, and capability, most of the cables used in the A/V industry fall within five main groups: individual conductor, twisted-pair, coaxial, fiber optic, and custom bundles....Read moreLecture Hall System This lecture hall is a large room capable of seating approximately 80 students with stadium-style seating, providing clear and unobstructed views of a large screen at the front of the room, along with two large projection screens. A large lectern is located in front of the room, serving as the central point for content delivery and control....Read moreThermal Management Part 1: How Hot Is Too Hot? By Steve Somers, Vice President of Engineering Thinking about the topic of thermal management brought back memories of old round table discussions at college with an old ham radio buddy named Don. Don found it quite challenging to build radio transmitters from scratch; but, not the regular types of projects you would see in do-it-yourself articles....Read moreThermal Management Part 2: How Hot Is Too Hot?

I think I see a couple of bandaged fingers out there. I'm sure that many of you have some interesting stories about overheated equipment and systems....Read moreRecognizing Poor Video Imaging and What to Do About It By Steve Somers, Vice President of Engineering Good video imagery is a relative term…relative to what you are used to. Most people have yet to witness, much less realize, the image quality our NTSC system can deliver. It should be no surprise that, in many instances, the same will be said about our new digital television system, ATSC. Why?...Read moreSystems Integration: What's the Plan? By Steve Somers, Vice President of Engineering Do you have a five-year plan? Five years seems to be the most typical time span for planning ahead… fairly close in, but still far enough out to make the job of planning fairly difficult....Read moreLumens and Lumenaries By Steve Somers, Vice President of Engineering There's often talk about standards and standards organizations in the electronics industry, but at INFOCOMM this year, we plan to see them in action. The action I'm referring to is the lumens measurement project taking place within the 1998 Projection Shoot-Out®....Read more
