Working With Audio Signals

For most of the past century, working with audio signals was a very straightforward process. The audio information was converted to electrical signals in the form of a varying voltage between the two conductors in a pair (balanced) or between a conductor and the ground reference (unbalanced). The bandwidth, frequency response, distortion and noise...

Post Production Ask The Experts

IntroductionIt’s a familiar scenario: A client calls with an urgent transfer request. It may be a movie sourced at 23.98PsF that needs conversion for broadcast, and the client needs an HD version at 1080 50i with Dolby E audio and an SD program at 625 50i with PCM audio, as well.

Eye to Eye: Video Post-production

My first direct experience of video post-production involved hauling a heavy Sony U-Matic tape machine up a flight of stairs before going back for an equally heavy playback deck, a bulky CRT monitor and a large box of interface giblets. That was in 1978. 33 years on, an Apple Mac does the whole editing job a great deal better, faster and more econo...

DVB-3DTV: A Milestone

In 1822, George Stephenson set his Standard Gauge for the world’s first steam railway at 4 foot 8 inches (1.44m), to match a nearby wagonway that worked well at Killingworth Colliery. Despite Isambard Kingdom Brunel building the London-to-Bristol line (1838) on what he considered to a better 2.2m ‘Board Gauge’ (he was right!), the Gauge Act of 1846...

BVE 2011 retrospect

BVE 2011 had much of the buoyancy and buzz of an IBC. The organisers claimed an attendance of over 15,500 visitors and 240 exhibiting companies.

Eye to eye: The changing face of video displays

Video display technology is progressing so fast that the phrase 'More revolutions than a banana republic' inevitably comes to mind. No offence intended if you have just taken over as president. From the 1930s to the present century, television display was dominated almost entirely by cathode ray tubes. Competition then arrived in the form of plasma...

Deskilling or reskilling

I recently went to a demonstration of some really terrific new technology. This is not a technology column so I do not propose to go into too much detail about why I was impressed.
