If this is the "Drama" channel on UK Freeview, my

It is often woefully out of sync, but sound was
late (it's easier to spot sound leading usually).
Inspector Lynley(?) was about 8-10 frames this
last week. I don't think there is anybody
technically competent involved in the TX process.
It is obviously a technical issue as the entire
shows have been massively off all the way through.
They're shot on film too, so there would be a sync
plop on the leader for telecine to check (and they
would have done that).
Note that nowadays there are few points in the TX
chan in where a human can accurately tell sync.
Paul R. will confirm that there were two CRT
displays still used in regional news here, one for
the Sound Super and one for the TM, to assess sync
on stuff leaving the studio (and in preview,
obviously), but that's it, and the studio in
question does exclusively NCA.
If something pre-recorded (i.e. all drama, for
example) gets 'ingested' wildly out, there is no
magic way it will be spotted before transmission.
