Eye-to-eye: 2011 highlights

“Broadcasters must climb up the ladder into high definition or they’ll get their ankles chewed by the computer industry”. Memorable quote from a manufacturer of video standards converters nearly 30 years ago when NHK was trying to establish its original 1125-line (1080-active) 5:3 aspect-ratio ‘Hi-Vision’.

Storage and archiving

Anyone looking closely at a helical scan video tape mechanism, particularly the miniature variety, might be forgiven for wondering how such an elaborate technology ever came to be invented. The first experimental video tape recorders were essentially audio recorders running at very high speed to achieve the bandwidth needed for television signals....

THE RISE AND FALL AND RISE AND FALL OF POST PRODUCTION

I was sitting in the pub the other day and met an old editor mate of mine. We started chewing the cud about post-production and, inevitably, the glory days. When I first met him, in the early 80s, I hadn’t even started my career in broadcast leasing. He, meanwhile, had a money clip full of £50 notes and was the talk of the town. He didn’t have enou...
