Err - not quite. The SMG and Carlton London feeds were displaying a nasty fault when they were actively aspect switching - really nasty glitches during aspect ratio changes... This was unacceptable for non-test transmissions.
The feed carried on Digital Satellite is not technically the analogue feed - although it may look identical.
It is derived from the digital feed - but with the aspect ratio converters (ARCs) permanently set to output in 4:3 only - whatever the aspect ratio of the programme in the network feed - outputting 4:3 full frame when the show is 4:3 and 14:9 when the show is 16:9.
This is not the same as the analogue feed, as the ARC for Sky digital is at NTL, and the ARC for the local analogue service is not.
(Apparently INTERNALLY ITV are using the same system as the BBC now - the feed from presentation is now permanently widescreen -with 4:3 shows run as 12P16 12:9 pillarbox in a 16:9 frame... This cannot be run on Sky (Sky need either full frame 4:3 or full frame 16:9) - and the ARC required to convert this 16:9 feed to either 4:3 full frame or 16:9 full frame ALONG WITH the correct data header indicating the aspect ratio to Sky doesn't work properly yet... UTV are fed differently - hence they work...)

Of course, SMG's system was also compatible, as was London's when it was made available to NTL (the other ITV stations' system is currently incompatible).
SMG and Carlton have resorted to sending the analogue feed to NTL because of the glitching problem, no doubt being caused by some nasty hard-switching somewhere. As I understand it the UTV feed is not routeable to the analogue feed for whatever reason and hence the channel is in widescreen when in fact it acually shouldn't be until NTL get the problem sorted out...

) a 14:9-compatible feed is not possible from UTV's transmission centre hence they are not able to switch to 14:9. So the glitching will have to remain in the coming weeks until NTL sort out their end and fix UTV's feed in the same way as the other channels.
