Once again Technology over Content...
"But don't underestimate the appeal of O-O transmission to two groups of people. One is BBC middle management, who will form "a metadata working group" at the drop of hat, and spend years having meetings which typically achieve nothing - but consume a lot of license fee money.
The other group is TV manufacturers, who are facing a grim future as undifferentiated, commoditised floggers of flat panels. O-O might allow them to sell more expensive sets.
And with 3D flopping, they need some magic marketing woo from somewhere
I suggest that, for once, the brains at the BBC would think about the content they broadcast rather than the technical methods that accomplish the that aspect of delivery.
Technically, HD video and sound is all well and good but it does NOTHING to the diet of food-orientated, the shambling housing-orientated and the hard-hammered auction-orientated rubbish, much of which is badly upscaled SD, repeated Ad Nauseam.
This time, please, consider new and exciting, challenging and educational content before, once more, going down some technological cul-de-sac.
