Read it about 6 years ago in the 'Media' pullout section of the Guardian
newspaper. (An interview with a TV vision engineer). Also saw an item on the
'Blue Peter' prog' where the guy demonstrated the colour enhance device
using earlier BP programme material and a film from the 70's.
Presumably therefore applies to PAL video tape recordings and film archive
material. I know from what little video tape I have (8 years old) that even
now, the colours are starting to 'lose it'.
I've no other details. Hoping some one could comment.
