Nevertheless, you indicated effectively that cable companies by way of
having multiple channels will have less concern for the particular
quality of each one. To quote you: "who cares about one channel when you
are distributing
dozens?" =20
I can only presume it is not an issue for you people. Perhaps you do not
get the huge delay (100 to 200ms) that I have experienced. I can get
used to a degree of mismatch but extreme mismatch is very distracting.
What I am trying to say is it was never an issue (that I recall) when
analog recording, transmission and display was the norm. Now the use of
digital technology has apparently made a step backwards in the end
result to the observer. That it does not have to be so does not correct
the problem. The mechanism is there according to you, to correct this,
but is not always implemented for whatever reason.
What then is considered "progress" in TV technology? Surely, getting
synchronization right (automatically) would be a significant
achievement?

I don't believe that I ever said the cable companies were the culprits
in
this: only that they don't pay attention to their multitude of channels.
Indeed, most instances of bad a/v sync I see are the fault of
broadcasters.

Is it a case of apathy that no care is taken with lip synch? Does it
need a huge outcry for people to take notice? It is disappointing that
technology, complex and ever more capable though it is becoming, will
only be used to implement change where there is a decided profit,
whereupon the marketers of innovation will proclaim to the intended
audience that it is for their benefit.
Is there no quality standard that prevents transmission of impaired
sound/vision synch? If it is a simple matter to correct as you say John,
then clearly the cable companies you suggest as the main culprits, have
a lot to answer for.
Also, trying to make any sort of comment to a local broadcaster here
(where there HAS been a problem) is met with a brick wall. I tried to
contact one (TV3), which supposedly has a new all digital studio
facility, about lip synch problems about a year ago. They were very
evassive.
So, your implication about cable companies and their multiple channels
was that they will do the least they can get away with to maintain their
share of the audience. I hope this is not the attitude taken to the
provision of HDTV but I have the feeling it probably is.

It's quite easy to control, from what I've been told. Video encoders
have
adjustable throughput times, as do audio encoders. That it is not
controlled by broadcasters you watch means they're not really
broadcasters.
That it is NOT controlled by cable companies is an indication that they
ARE
cable companies: who cares about one channel when you are distributing
dozens?

I understand it is only those who have perfect pitch hearing (how many
would that be I wonder?)who can find the pitch difference annoying.
What is far more annoying from time to time and is actually quite common
(here anyway), is lip synch. problems. It comes from unusual sources. I
have noticed as much as 150 to 200ms delay. This is extremely annoying.
The local studio can produce it to a slight degree but is far more
prevalent and worse in overseas material. I have noticed that some old
movies received via satellite can have perfect synchronization but that
live and some prerecorded material can be very poor.
Why can't this problem be controlled to an acceptable degree?

Does that mean that "the vast majority of Europeans" don't mind
watching picture and sound at a speed that is 4% higher than the film
acquisition rate?

The 3:2 pull-down that 60Hz demands for showing film looks truly
appalling to the vast majority of Europeans. It's really horrid. NTSC
dvds sold here are rapidly junked in favour of proper ones, not only
sharper but much more regular smooth motion. From time to time, a
purchase deal for a US film-made programme goes wrong and we get a
standards-conversion of the 59.94Hz video instead of a proper rescan
of the film. Phone lines get hot with the public complaints.
