Truth Lies and LEDs

As an emergent technology within film and broadcast over the last six years, LEDs have generated strong opinions for and against, adjudging their capabilities and relative merits, when compared to traditional light sources. Development has seen them grow from the small coloured pinpoints of light on your stereo or TV, to a level where they can prod...

Television has proved the most popular and efficient form of human communication since the evolution of speech and the development of the written word. The industry has come a long way in a short time and still has a huge future, whatever the delivery route or the receiving platform.

Eye to Eye: Whats even newer in test and measurement 2010

A year is a long time in broadcast test & measurement, which is just as well because that is when this column previously focused on it. Given the current push to establish 3D as a permanent feature of the broadcast landscape, one might reasonably expect T&M kit designers to be heading along the same road. Hamlet and Omnitek certainly are but it see...

Frame Rates and HD

Much has changed since the 25 Hz and 30 Hz frame rates for television were defined over 60 years ago. In Part 1, last month we noted how the USA (followed by others) adopted the 1000/1001 frequency offset to produce the 29.97 Hz rate and the resulting drop-frame timecode. Of course at that time, 1953, they could not imagine the consequences of thei...

Eye to Eye: Acquisition and Production

Back in the days of the Audio Fair which annually graced London's Russell Hotel, my co-hack Frank Jones of Hi-Fi News put his head into the KEF Electronics demonstration room and bellowed the time-honoured question "What's new?"KEF was showing established products that year so its founder, the avuncular Raymond Cooke, responded with his own questio...

Film Affect

As shooting on film for TV applications is increasingly being replaced with HD, there is a growing tendency for people to wish to apply film tools and methods to origination when using the electronic medium. However, unless aiming for a specific look that cannot be achieved any other way, it can prove more time consuming and costly to work this way...

Pushing Air- the art of acoustic design

Acoustics is usually regarded (or often disregarded) as a black art that is practiced with no discernable science involved, with a great reliance on ears for measurement and blind faith as a method statement. Nothing could be further from the truth in the professional study of sound, with many practitioners furnished with several degrees and a weal...

Eye to Eye: Whats new in audio 2009

Part of my day at SATIS recently was sent discussing with Neutrik the dodgy issue of sexual compatibility, a subject not mentioned in my report from the show for TV-Bay last month. I had recently invested in a Roland Edirol R-44 solid-state audio recorder. Used in conjunction with four Rode phantom-powered capacitor microphones, it makes an excelle...

Eye to Eye: Content Protection 2009

In the early days of audio and video recording, the limitations of analogue devices provided a fairly high level of content protection by ensuring that any captured signal was either inferior to the original or fairly soon became so. Optical digital media changed all that, allowing practically perfect copies of speech, music, still images and movin...

NAB 2009 report

By general consensus, this year's NAB Spring Convention, or 'NABshow' as it styles itself, was one of the best ever. Wider aisles and a respectable rather than manic level of attendance made the event, in the words of one exhibitor, 'Business Class'. NAB was always the prototype show where you could sense the directions in which manufacturers were...
