As facility operations become more complex, automation systems must follow suit

The broadcast industry may take audio almost for granted, but the routing, mixing and monitoring of audio are complex issues with no easy answer

Lens technology may be the first of several enabling technologies that led to the development of television.

Centralized operations are not always the most successful and economically viable because either the labor saved is not sufficient or the interconnection cost is too high.

Video routing is still the hub of all broadcast and production centers. An examination of multi-format, HD and SDI routing techniques and technology

For TV stations and production facilities that make virtually all of their income from SD, implementing HD represents a challenge. John Luff provides an HD roadmap

What should we, the non-cognoscenti, be doing to prepare ourselves

Broadcasters have been infatuated with HDTV since the 70s. In 1987, they asked the FCC to carve out spectrum for HDTV. But, back then, practical hardware

What could be simpler than taking a unidirectional signal in and passing it on unchanged?

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

John Luff explains the process and history of archiving, and the reasons that archiving systems and good “digital librarians” are needed in the industry.

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

Test and measurement equipment is key to installing and operating a television plant. Consultant John Luff discusses what equipment is needed

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

Video servers are not the same. This month's Technology in Transition column reviews the formats used by various manufacturers, key feature differences and best-fit applications.

Increasingly, production personnel expect that any format can be converted to any other

I often have wondered what percentage of all editing done for television, broadcast and non-broadcast, is done for news purposes.

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

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

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

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

The conceptual design of video facilities has begun to move away from the paradigm that has sufficed for the analog facilities and the transitional "digital
