Getting from here to there digitally
In the past, the most often used method to get the station’s signal to the transmitter was with a microwave transmitter and receiver. Covering distances from 3mi to 30mi was not difficult, but now stations are accomplishing this vital task in various ways...
Converting to digital III
When considering the conversion of an inductive output tube transmitter from analog to digital, many questions arise that need to be resolved. Changing over the transmitter is just half the problem. The RF plumbing to combine or switch the transmitter outputs is just as important. A poorly designed or installed RF transmission system can easily take a station off the air for days no matter how many transmitters the station has. This tutorial will present the challenges facing one station as it plans for the conversion...
Converting to digital II
When considering the conversion of an inductive output tube transmitter from analog to digital, many questions arise that need to be resolved. This series of tutorials aims to lay out the challenges that need to be addressed and present some of the answers one station came up with while planning to carry out its own conversion. In this installment, the challenge of switching between two full-power transmitters as well as frequency changes and control issues will be discussed...

Converting to digital
With the transition to digital-only broadcasting fast approaching, broadcasters are considering what to do with their analog transmitter as well as how to handle redundancy for the DTV transmitter. At the end of the transition, approximately 1300 UHF DTV stations will be on the air, and many of these stations will be using a single IOT amplifier. Other stations will not have a backup transmitter or the budget to pay for one. The stations lucky enough to have an analog UHF transmitter can convert it to digital to provide redundancy. This tutorial will present the challenges such broadcasters face as well as follow one station as it plans for its conversion...
Replacing the CRT III
The replacement for the CRT display is here today in one of the flat-panel display technologies. These monitors come in a wide array of sizes and features. Which one will match or go beyond the capabilities of the CRT is a very important question. Which one gives the most accurate display and what is the new standard for judging color? With CRTs on the way out and with so many choices, it’s hard to know which way to look...

Replacing the CRT II
The LCD display is one of the most popular display technologies available today. It is in wide use in applications from computer monitors and consumer televisions to professional broadcast monitors. But it’s taken the LCD more than 40 years to get to this point, and it still has shortcomings when compared to the CRT. What are these limitations and how are manufacturers overcoming them?...
Replacing the CRT
The cathode ray tube has been an integral part of television since the beginning, but soon it will be obsolete. Today’s display monitors come with a wide array of technologies and capabilities. But with these new technologies come new questions: What are the new display technologies and what new standards are there for judging video images? Not too long ago, the only display was the CRT; but with so many display choices now, it’s difficult to know which to choose...

Fiber-optic basics
Fiber optics has found a place in the broadcast facility, whether it’s providing an HD link between different floors of a building, connecting disparate cameras in a stadium or even connecting an ASI link between the studio and the transmitter. But how much does the average engineer know about this vital link in the broadcast chain? This tutorial will provide a basic understanding and some practical tips on how to install, test and troubleshoot a fiber-optic system...
