Picture quality problems right at source, not display

Just watched the two rugby games on the BBC, using NTL cable through my old Pio502 - What a difference between them !!

The game from France was only 4:3, with black bars left and right as part of the widescreen BBC source, but the picture quality was superb. Both still frame and fast action was encoded superbly giving an overall great picture.

Then game the Wales/Scotland game. In widescreen this time, the still(ish) frame shots were fine, but as soon as the picture was panning or there was a lot of action in shot, it just turned into a grainy, "boxy" mess !!

Perhaps the BBC need to spend a bit more on the MPEG encoders they use, and it shows that to compare one plasma screen with another, it would have to be at the same time with the same image. No good going from shop to shop when the source - even from the same channel may have changed completely....

That's a really interesting White Paper cybersoga; StooMonster likes data and analysis.

Facinating that "at lower [bit] rates some pictures were better delivered via SD [plasma, than HD one]".
