There's a lot of camera and editing techniques employed now, which I think
are the result of arty-farty thinking, and often at least incongruous in a
particular production, if not downright inappropriate. One that seems to
have come in recently, is where a show like for instance "The Hotel
Inspector", has a presenter who needs to present some parts direct to
camera. They used to look at the camera, and the good ones could get the
right 'expression' into their eyes to 'engage' the viewer. You actually felt
like they were talking to you alone. Now, they seem to talk to some unknown
person standing 10 feet behind the camerman's right shoulder. This gives
their eyes a strange 'disconnected' look, and it feels sort of rude of them
to appear to be talking to someone else rather than me.

I also hate the waggling camera shots, the rapid zooms and de-zooms that
leave the focus lagging a couple of seconds behind, and the way that cookery
programmes are shot now, with the camera zooming in on a single tomato seed
in the mixing bowl, before a high speed de-zoom to some arbitrary ingredient
pile or implement, followed by another high speed and defocussed zoom to the
spot on the end of the presenter's nose, followed by a rapid drop back into
the mixing bowl. WTF are they trying to show ? How is that sort of crap
appropriate to that type of programme ?

And now that "The Bill" has got a 9 o'clock slot, they've changed the
shooting medium to something that looks altogether 'wrong', changed the way
it's lit, presumably to try to give it some kind of dark edginess, added the
most inappropriate incidental music, and changed the characters into moody
hard-men. That show had a good format before, and wasn't suffering falling
ratings, so why try to fix what ain't broke ?

And it never starts on time ... :-)

Thanks; as Johnny Carson used to say, "I did not know that".

So how does NTP work in this case? I'm guessing it must contact some
entity over "the network" (meaning something external to my computer) in
order to determine the actual time, no? How does this work? Who does it
contact? (Short answer will be fine.) I do notice that one of the NTP
commands is

[\\computername] /SETSNTP[:ntp server list]

so I assume my computah keeps a list of servers "out there".

(So I guess if my computer is contacting a time server out there
periodically, but my clock was still off by 5 minutes, then the RTCC
must be *really* inaccurate.)

By the way, you can type "net time ?" to see the "help" info.

Are you sure that's what it is ? Any HD that I've seen is just that. A
perfectly 'normal' looking picture, but with a higher resolution. Why should
a higher res camera change the tonal composition of the picture ? (assuming
that it is being shot on video). Looks more like they've changed from film
to video, or the other way round perhaps. Or are maybe using a video mode
that attempts to simulate film, something like that. I saw it before on the

Hmmm. Not what I read, but as you are 'in the trade', probably more
accurate. Still, with what they've done to the programme now, I can't see it
picking up many new viewers, and I think that many of the existing ones
won't stick around long either. It has now lost all of its humour and
'feelgood' factor. It was sort of like a latter day Dixon of Dock Green in
some ways. I think it showed quite nicely that sometimes, an average
copper's day is more about helping old ladies cross the road, than screaming
down that road at 80 mph in the area car to get to some pervert's house
before he has a chance to murder the child he's abducted, and wipe his hard
drive. Every storyline now seems to be about a CID operation, with uniform
backing them up. All of the stories seem 'dark' and 'moody'. They've turned
the head of CID into an arsy, sulky, depressive, and Jack Meadows into a
growling grumpy old sod. If this is what the programme makers think is going
to save the programme, then I think it probably will be pulled by Christmas,
and sadly, not really missed.

What the NTP process does is essentially to monitor the local clock
compared to a reference to understand just what its errors are, and
synthesize a "perfect" clock from it. The synthesized clock can remain
within a few microseconds (or better) of a reference timekeeper all the
time.

Maybe that works if you leave the computer on all the time. I started
the ntpd daemon early in the morning and by late afternoon the time
was, once again, way the hell off. Since I only care one time, one
day a week what the time is I have set up crontab entries to do the
job.

I see the problem, that seems to have been missed by those suggesting a
software kluge that periodically stuffs the clock with the right value.

Here's an idea I haven't seen in this thread yet: If you're really
interested in getting to the bottom of this problem, how about trying to
determine whether it's the actual clock (RTCC hardware) that's off, or
whether the OS is missing interrupts or there's some other software
problem?

How about booting the computah under some other OS, say Windoze or even
DOS, and running a utility that checks the RTCC for accuracy? (Don't
know of any, but I'm ass-uming that there are lots of such utilities out
there. Maybe there's even one for Linux.) That way you could know
whether the clock needs to be tweaked (new crystal as suggested by
others), or whether it's an OS problem.

Just an idea.

As I said earlier, if the local clock (crystal, whatever) is
free-running (not synced to a standard reference using e.g. ntpd), it
*will not* stay accurate because it *cannot* be running at precisely the
proper rate all the time. No matter how often you set it. No matter how
often you tweak that little capacitor (which is very likely *not there*
to tweak in the first place. You can *never* get it "right on". The
question is not whether it is ever "correct", but only how fast it
diverges from "correct" whenever you stop messing with it. The
brilliance and elegance of NTP is that it can take that crappy,
imprecise, piece of temperature-sensitive quartz, and from it synthesize
an amazingly precise timekeeper.

Sounds OK to me, except that I just checked and reset my computah's
clock (I use a little Windoze utility called "NIStime" that gets the
time from NIST); it was off by about 5 minutes. Haven't synched it up
for at least 6 months, so I know my RTCC is at least that accurate.
(Running W2K, so I assume that no software process is adjusting my
clock.) Shouldn't most PC clocks be about that accurate? (Older MB,
forget exactly what, can find out if you're interested.)

Most crystals used in computers are within ten or 20 parts per million
of the frequency stamped on the case (you can get a lot more accurate
ones, but computers don't need it). AFAIR, those little cylindrical
"clock" crystals that run at 32,768 Hz are at least ten times poorer,
and far more temperature sensitive to boot. I think the *best* you could
expect from one of those without special treatment would be about a
minute a month.

Ah, yes. That's it I think. I was trying to figure just what they had done.
I always try to shoot photos where possible with available light, and always
have both with 35mm film, and latterly, digital. Personally, I think it
gives a more 'natural' look. So in the case of The Bill, it's probably a
two-way thing. Different lighting directors who believe in artificially
lighting the scene, and a desire by the writers / producers / directors (??)
to try to make it look 'edgier' to go with their new post 9pm dark
storylines ...

Hope I'm not belaboring the point here. I just ran "net time" again and
got the error message "Could not locate a time-server". So I assume that
even if that process is running on my computer, as someone else here
asserted, it's not doing anything to my RTC, as there are no
time-servers to query (that it knows about). Therefore, the time my
computer displays is the actual RTC value. Therefore, it seems to be at
least as accurate as you've stated (about a minute a month), which
actually seems pretty damn good to me. If it gets off by 12 minutes a
year, resetting the thing once annually would yield a clock that should
be close enough for most folks' purposes.

Don't remember that one - do remember a Columbo movie where a VCR is used to

to give the murderer a witness to prove that he was at home at the time of
the murder. Quite a new idea at the time - the movie was made before launch

I reckon that TV companies must now use these laptops with very rough RTCs
! Have you noticed that now programme material is not networked from one
region into some or all of the others, and adverts are no longer 'local',
there is not any need for accurate cueing points around the network, so
advertised starting times are not even nodded at ? I checked the starting
times of about half a dozen programmes tonight, using the teletext clock,
which I believe to be accurate, and not a single one started within 1
minute of the correct time, and a couple of them were off by several
minutes. Just another manifestation of declining standards throughout the
civilised world ... :-\

It's not just between broadcasters, the BBC does it between their channels
as well. Their 'Points Of View' viewer complaints show have done a few
reports on viewers complaining about different times on BBC1 and BBC2, at
least one of which had one of their presenters switching between the 2
channels at programme change to demonstrate the problem.

The problem (which they actually proved was real - surprised they were
allowed to show that on BBC1) is that BBC1 often runs 2 minutes early and
BBC2 is 2 minutes late. Switch one way and you have to wait 4 mins for
programme start, switch the other and you miss the start.

But then the BBC don't seem to care about viewers anymore - the recent
Wimbledon problems where the schedules for the 2 channels were suddenly
switched at the last second for 2 evenings (causing people recording the
last episode of Robin Hood to miss it, needing it to be rebroadcast a few
weeks later - they switched schedules too late for PVR's to catch the
move).

Quite how they thought that helped anyone is a mystery - anyone recording
Wimbledon would have missed it and had BBC1's normal schedule recorded and
anyone recording the normal BBC1 schedule who would have got home to find a
tape / DVD of wimbledon (or in the case of PVR's nothing at all - the
change made recordings just cancel).

No - The Bill has never used that. Or rather not in general - it may have

The current ones are shot HD using progressive scan.

Depends - the actual ad break times are pretty accurate between some of
the companies - the idea being to prevent channel hopping when the ads
come on. You'll just see ads on the others. Hence the way they crash into
the break on progs not made with this schedule in mind. And most of ITV
comes from just one playout centre, so should be synchronised across the
country.
Start times for progs have never been accurately published. They've always
been approximate - apart from on some data points in the evening.


Here in Australia I got documentary proof that a station was
deliberately running late. See

http://groups.google.com/group/aus.t...a580334e9ff9f2

I had recorded that channel that evening, on a PC that has its clock
synchronized to an accurate clock, and the times given in that schedule
were to within one second of when the material was actually broadcast.

They just weren't the times that had been advertised.

BBC's apparent inability to keep to its published schedules back in the
early 1980s. This is nothing new.

Australia's counterpart, the government funded ABC which also doesn't
carry advertisements, is also apparently unable, or unwilling, to
broadcast things when they say they will.

I suspect that, as with the commercial stations, it's deliberate. I'm
just less than clear what the motivation would be for a non-commercial
station.

If you give it some thought, it's near impossible to make a prog run 'to
the second', as some seem to want. You could, of course, always make it
shorter and fill the gaps with trails etc - allowing the next one to start
on the second. But that would bring even more complaints. ;-)

Maybe not with live shows but when shows are pre-recorded the broadcaster
knows the exact length of each show long before broadcast so should be able
to make the published schedule fit what is actually broadcast - like if you
broadcast a pre-recorded show at 8pm and you know the recording is exactly
60 mins long then advertise the next one as 9:02 to allow for trailers not
9:00 and run late.

Why is BBC1's 'ONE SHOW' always broadcast 2 minutes early (both start and
end times) - I know it's live but showing just 1 trailer before the show
would make it run to schedule, surely showing extra trailers would bring in
less complaints than viewers missing the first 2 minutes of every episode.

Do people really switch on at the exact minute? More of a problem with VHS
recorders where you're swapping channels to record two progs. Luckily PVRs
get round this - to some extent. But the one thing you can be sure of is
programme companies not cooperating with one another just for the viewer.

Because it's difficult. The right way to have done it would have been
to do a function call from an RTC (real time clock) every time some
application needs the actual time. IBM or MS, in their infinite
wisdom, elected to install an RTC on the mainboard, copy its contents
to the operating system, and then let the OS have the time available
without having to read it from the RTC chip. Great idea in the days
of 4.77MHz CPU's, which don't have too many operations per second. Not
so great an idea with 3GHz processors, where the much larger number of
operations per second will produce far more lost interrupts per
second. The result is clock drift, always in the form of losing time.
Most apps that require accurate time (i.e. SMTPE time code
synchronized NLS editor, SONET, etc) will usually get the time from an
external source, rather than use the OS or even the RTC.

If you use the NIST SNTP server you'll be as accurate as how
frequently your SNTP client updates.

Of course, it would be nice to know one's computer would maintain
accurate time even if, god forbid, it was somehow disconnected from The
Network ...

There are internal GPS receivers that will supply accurate bus timing.
http://www.symmetricom.com/products/gps-solutions/bus-level-timing/

If your worried about losing sync when the internet hickups, you can
go cheap and just use the NMEA-182 time data from the GPS or the 1pps
time ticks. Last resort is a WWVB time receiver, which works quite
well in the middle of the night, when you probably don't need it.

Incidentally, I had an odd experience back in the stone age of PC's. I
was doing work for a local PC dealer. I wrote my first, and almost
last, Turbo Pascal program that displayed an analog clock on the CGA
screen, and planted it on a PC in the window of the store. I knew it
wasn't terribly accurate, but it was tolerable (at about 5 minutes per
day). Shoppers would walk up to the window, look at the computer
screen, and then reset their wrist watches using the PC as a
reference. Of course, the computer MUST be more accurate. I
eventually had to put a sign in the window warning that this was a bad
idea.

Yup. Most of these computers use motherboards which are manufactured

You should stay away from NIST (and all other stratum one servers) to
avoid overloading their server unless you have a real need for high
precision -- REALLY high. Otherwise, find a good stratum two server to
connect to; you'll never know the difference. There are a lot; just

Functionally impossible. By adding money, you can reduce the drift rate

Because it's difficult. The right way to have done it would have been

I don't agree. NO CLOCK, running alone, can be really accurate over the
long term. A much better way is to take the output from a crummy,
inaccurate *but low cost* clock and using an external time reference,
synthesize from it a local clock of simply amazing accuracy.

NTP solves the problem completely, and at a very low cost (processing
cycles instead of expen$ive hardware). NTP works even if the computer
it's running on has *no RTC* (in the hardware sense) at all. All it
needs is some sort of interrupt generated every N cycles of the
processor clock (N is any integer that produces regular interrupts a few
times a second; the actual interval is not important).

Live or recorded, it is perfectly possible for broadcasters to maintain
program timing to the nearest second; we used to do it back in the
sixties, when nationwide network switching was synchronized by people
watching Western Union clocks on the walls of broadcast stations all
over the country. What has happened is that broadcasters either don't
care any more, or there is some commercial advantage to playing fast and
loose with the timing. My bet is on the latter.

Yes, they do. Timing is based on the number of frames in the entire

million from any major network. You can use the frame rate, line rate,

And so much is automated these days, playout wise.

That just makes the switching times more precise -- IF the operator

program timing to the nearest second; we used to do it back in the
sixties, when nationwide network switching was synchronized by people
watching Western Union clocks on the walls of broadcast stations all
over the country. What has happened is that broadcasters either don't
care any more, or there is some commercial advantage to playing fast and
loose with the timing. My bet is on the latter.

That's my feeling too. It definitely used to be much better here in the UK,
than it is now. If a programme was billed to start at 8pm, then it pretty
much did. Now, it is often several minutes late, after they have finished
showing genuine commercials, and then long trailers for forthcoming
programmes. Even the BBC is now poor, and they only have their own trailers
to factor into the equation. I really don't think that they care too much
these days, as the 'networks' are no longer formed from independant regional
stations, each with their own control centre, which had to synchronise, and
jump on and off the network, as the programming and commercial breaks
dictated. It probably is just a combination of 'no need', someone's
smart-arsed thinking about channel surfing, and the general 'don't really
care' attitude that's pervading everything we do now ...

Pretty much sums it up. But in those days few had dead accurate clocks
which are so common now.

If you'd said 9 o'clock you'd have been right - that was one data point
for the network, the 9 o'clock news.
