The evolution of vision mixers
|
 |
At the heart of any multi-camera production is a vision mixer or production switcher as some people call them. Its core role is the switching of different sources, primarily cameras, often VTs and sometimes incoming external sources such as remote feeds from broadcasters. Even for non-TV types, thats relatively simple enough to get your head round several different incoming video signals can be switched from one to the next. Vision mixers come into their own when you look at their secondary features of keying graphics, transitions and digital effects. |

A credit to whom?
|
 |
Just over 40 years ago I was involved in the formation of the Guild of Television Cameramen as an independent non-profit-making international organisation that cares about television camerawork and the people who make it their craft. The GTC today has over 1,000 members, in the UK, Europe, Australia, Russia, Singapore, South Africa and the USA. The majority work in aspects of television ranging from production through documentary and drama, news and current affairs, sports and light entertainment, to corporate video. |

Commercial break
|
 |
The first commercial to be shown on British television was for Gibbs SR toothpaste, transmitted at 20.12 on 22 September, 1955. Back then, according to Lord Thomson, the founder of Scottish Television, commercial television was a licence to print money. |

So what is Digital Television - Part 1
|
 |
It is tempting to think of digital television as something very scientific and even complex. But when we view the end result, we find something very familiar; something television engineers have sought since the very beginning¦an experience that just keeps getting better and better¦quality video and audio conveying great entertainment, sport, movies, and news to the viewing audience. The only thing new in digital television is the way the message gets from here to there.

Watching Television
|
 |
The pictures on this page give you a small insight into my life. The first is a picture of the television in my living room. At the time of taking the picture I was watching the English cricket team losing in high definition. |
