A look at the past, present and future of video storage. Which storage strategy fits your needs?

For the next four months this column will focus on four interrelated and interdependent areas of television technology: automation software, data archive

Since the invention of the hard disk there have been predictions that linear media, including video tape, will eventually disappear. Not even a decade

Just when everything is going well in a production, the audio operator often becomes the center of unwanted attention. One moment the singer on stage

Television engineers tend to think of the world as entirely digital these days. CCDs for image acquisition (digital capture), digital video recorders,

The broadcast engineer of today spends his time worrying about software, video servers, DTV and the continual upgrade of the facilities he manages. His

Controlling reality is always expensive, and creating illusions is sometimes nearly as expensive. Entire motion pictures are being created in computers,

In the second installment of four related to automation and asset management, this month we consider data archive systems.

HD broadcasts over DTV channels hold the promise of delivering vastly improved pictures and sound, along with data that can augment the linear video medium in an age of hypermedia.

Compressed video has enabled businesses that were only dreams at one time.

Broadcast stations used to be largely autonomous. Some still are.

A decade ago, would any of us have guessed that today we would see a rapidly expanding market for HDTV programming and a demand for HDTV hardware? Perhaps

The picture is not improved by upconverting a 525 signal to HDTV for DTV transmission. For many years consultants, equipment designers, production professionals

My fascination with science, and physics in particular, made playing with light even more interesting.

As the number of inputs and outputs grows the total count of crosspoints grows. Though complexity is high with virtual crosspoints, the relative cost

It is clear from the compression ratios that must be achieved that every opportunity to make the job easier ought to be taken. In the early 1970s I remember

JPEG 2000 offers advantages, but at high bit rates.

Master control is undergoing dramatic changes. How will they affect you

In 1939, when General Sarnoff broadcast the first live television show at the World's Fair in New York, synchronization was critical to the ability to
