[net.tv] TV & VCR standards

misha@daisy.UUCP (Mike Umansky) (01/10/86)

Hi.
This is a question for anyone who knows about TV and VCR standards.

First, a story:

A friend of mine in Germany has sent me couple of video cassettes
with movies that he recorded over there with (I think) PAL standard.
When played on our NTSC VCRs, there is nothing but snow on the tube
and sound is completely garbled.  Then I sent him couple of tapes
I bought locally.  He recorded couple of movies on his machine, but
when he played the cassettes back he got nothing but snow on the screen
and garbled sound.  Then he sent the cassettes back to me.  When I
play them on my vcr then sound comes out ok except it is a little faster
(I guess maybe tape transport speed difference - Is it AC freq dependent?)
and I could see the picture except that it was vertically unstable.
So, I got myself an old tv and changed the vertical hold capacitor.
Now I have it stable but like I said it is a little faster than normal.

Now the question is,  are the VCR tapes made for USA different from
the ones made for Europe???  Would it be too hard to create a translator
that would go between an European and an American VCR, probably at the
composite video/audio level???

Thanks in advance for any information!

You are a victim of non-standard television.  You will NOT be able to send
tapes to your buddy or vice-versa.  The PAL standrard implies that it is
different from our NTSC standard, which it is.  The European VHS machines
even record at a slower speed.  Our T-120 tape is the same as their E-180.
So, they get 50% more recording time per tape.

The tape is not different.  I sent tapes to my mother-in-law for her to
record the last season of Dr. Who.  I couldn't play them here, but I did
get them digitally converted.  That job cost me about $1700.00.

As for building a standards converter, forget it.  Professionally built
units cost $20,000.00+.

Your only hope is if the world decides upon a standard HDTV format,
until that time comes, either of you will need to buy a vcr/tv combination
that will play the other person's tapes.

I too have a problem with US/European standards.
We had our wedding ceremony and reception video taped (VHS).
My wife has relatives in Norway who have a beta system.
They had asked for us to copy our tape from VHS to beta
and send them the tape for those people who could not attent
the wedding. This sounded good to me. I went to my local
video store who had quoted me a price over the phone for
$25 to copy a 2 hour tape from VHS to beta. When I got there
with the tape we spoke about about what I was doing and he
informed me that the copy would not work due to the different
standard. He told me it could be copied digitally for about
$175 for a two hour tape. He said the quality of the tape
would suffer however. I should expect colors to wash-out
and at times could lose verticle hold.

My wife and I are debating whether to go ahead now with the
copy now that it will cost us $150 more than we origionally
planned especially when the quality of the copy will be poor.

My question is: first, is all of Europe on the same standard?
Secondly, has anyone had an experience with such a copy effort?
Will the quality be worthwhile? I would hate to tell our relatives
that the tape is on the way and have them let down with a trashy
copy job. Does anyone know of a firm that would do such a copy
for me (I live in central NJ, but would be willing to send it away)
my local video store would have to send it out himself.

Any advice would be greatly appreciated, both here and abroad.
If there are sufficient interest and/or responses I would be
glad to post a summary to the net.

Boy, is that guy full of shit.  A digitally converted copy will actually
give a more stable copy, as the converter also has built into it a time-
base corrector.  The TBC generates new vertical and horizontal sync.
Most of the newer digital converters use frame store, so if the original
picture drops out, glitches, etc., the copy will continue w/o any glitches
in the vertical or horizontal sync.

I have converted Dr Who tapes, that were VHS PAL, and I got excellent copies.
So, don't let that guy fool you.

Most of Europe is PAL.  France & Russia use SECAM.

I hope this helps you out a little bit.

There are three video standards in the world.
(1)  National Television Standards Committee (NTSC).  This is the
     standard used in North America, most of South and Central
     America, Japan, and a few other countries.
(2)  PAL.  This is used in "Free" Europe and the Third World countries
     that they developed.
(3)  SECAM.  This standard is used primarily in Communist counties
     and the Third World countries that they developed.  One exception
     is that France uses SECAM.

Quality of copying NTSC to PAL comes down to how much you are willing
to pay for.

	You dont need to spend thousands of dollars to convert from
	tapes in one system to another system. A much cheaper alternative
	is to buy multi system TV and VCR if you plan to see lot of
	tapes in other system.
	I recently purchased
		1) SONY trinitron 20" colour TV, KV2062-AEB for $480
		2) Panasonic VCR, NV 630PX  for $480
	Both were purchased from New York city.
	They work on NTSC, Euro PAL and UK PAL.
	Both have remote control and built-in converters(cable ready).
	They can work on 110 and 220 volts.
	(Actually I purchased them so that I can use them while I am
	 here and take home to India when I go back, India uses PAL, 220volts)

   For a lot less than that I bought a multi-system TV set and a 
multi-system VCR.  I can watch television in the US where we use
the NTSC system, record US shows and play US tapes.  I flip a switch
and I can play PAL tapes that my father sends me from Italy.

   The fact is that conversion from one of the european systems (PAL or
SECAM) to the american system is difficult due to the different frame
and horizontal scan rates.  But making a TV set or VCR that works with
both simply requires retuning of the various oscillators, and minor
differences in the signal-processing schemes.   As a result, multi-system
TV sets and VCR's cost little more their NTSC-only counterparts.

   Using a multi-system TV and VCR you can do a home-made conversion by
placing an NTSC camera in front of the TV screen where you play a PAL
tape (the sound can be transferred directly through a cable, as there
is no incompatibility there).   The quality is surprisingly good,
especially when you compare prices !!!

I don't know about Beta format, but we recorded some tapes on our VHS
machine (both from TV and with our camera), and they work fine on our
friends' machines in the Netherlands.  So there's some compatibility
between US and Netherlands in VHS, anyway.

No: Europe does not use a single standard. There are 3 major systems
in use:

    NTSC:  The US standard
    SECAM: developed by France
    PAL:   developed by West Germany.

The are several derived 'standards' that differ in the audio carrier
frequency, color carrier frequency, number of lines and/or number of
frames per second. So there are a total of about a dozent different
systems, all of them incompatible to various degrees. As mentioned
earlier, conversion is expensive, because you need a digital frame
buffer to do it.

You don't have to convert if your VCR can handle multiple systems
(and your monitor...). The following VHS recorders can all handle
most of the standerds mentioned above and are only slightly more
expansive than a normal VCR:

   National NV-330	   Panasonic NV-630PX
   Sharp    VC-477	   Akai      ???
   Hitachi  VT-39EM

Sony has a nice high resolution monitor (computer grade) that
can handle all these systems.

Are there such things as multiple-standard TV's (that is, TV's where you can
change the standard by flipping a switch)?  If so, are they expensive?
I imagine that such TV's would be useful for people who travel and, for
whatever reason, have to take their TV's.

Yes, on all counts.

Two examples lying about here are:

Sony PVM1271Q - 3 standards plus composite and analog rgb
Mitsubushi CT1051QFM - 3 (8?) standards plus composite

Both are 13" units with remote control, etc, probably pretty expensive.  The
best place to get one would probably be a NYC/LA type electronics house, or
have a local dealer special order on for you.

Flame me to death, but note that there are 3 systems (NSTC, PAL, SECAM), which
define the basic method of color transmision, but actually about 13 different
standards which have been implemented to suit local tastes, power and politics.

The Mitsubishi unit claims to handle 8 systems, and has a tri-color map showing
where it can be used.  About half the world, including the USSR, China, and
half of Africa and South America is in white - no TV or no compatibility...

In Switzerland (Geneva) I have used a TV set that could receive either PAL
or SECAM.  It was a Japanese brand, Hitachi I believe,  the system selection
was programmed by switches for each channel.  Once set up all that had to be
done was to select the channel and the appropriate (pre-programmed) system was
also selected.
There is another standard in England that has coarser resolution than the US
standard (fewer lines per frame).  I have heard of sets that could select that
system, but I don't think it is/was a color system.

    Whoooooooaaaaaa, there, Mr. Consumer Video... You just 
might recall that the EBU broadcast primaries are different from the NTSC
broadcast primaries.  The two colour gamuts (particularly with respect to
gamma precompensation) are not directly compatible, although it is possible
to get a pleasing aesthetic result.  Colour correction is an extremely
expensive proposition which * no one * does for $175/2hr tape.

     As for "jitters", there are good and bad line + frame interpolation schemes.
The first frame store PAL-B to NTSC-M converters suffer from severe motion
artifacts, such as the "jerky" tennis ball we've all seen during Wimbledon
matches of days gone by.  Early "Muppet Show" tapes are also subject to
severe temporal jitter.  The converter at my spouse's former employer was
horrendous in this respect.

     Yes, I agree that any digital frame store converter (which is not even
slightly the same thing as a TBC) should reinsert the sync and burst in
precise SC-H relationship for NTSC.  However, the ability of the digital
frame store converter to follow the original input signal is compromised
by a consumer VTR recording.  These are typically subject to gyroscopic
errors, long time constants in the servo loop controlling headwheel speed
and phase (done presumably to minimise "breakup" on cheap TV sets) and
very high amounts of subcarrier frequency modulation from line to line
due to stiction around the headwheel, etc....The input frame store has
to recover a sampling clock from all this crud, and it also has to determine
* which field is which * from trashy input synchronising information. 
Thus, a marginal PAL-B home videotape may actually *appear to roll*
because the input converter has lost genlock.  The image would still
* be fully framed * at the output.

     I don't think the guy was full of BS at all. When you start with a
trashy, timebase/frequency modulated signal that comes from consumer junk,
the possibility of successful conversions are fairly low.  I might add
that professional equipment assumes (in many cases) a priori that there
isn't a lot of IFPM on the timebase or colour subcarrier signals, so that
the correction loop bandwidth is small where the write clock and timing are
recovered. Thus, most professional video equipment has a very hard time
genlocking to trash like VHS and Beta.

    One can only hope that a uniform digital videotape standard will finally
filter down to consumers so that they can see what they've been missing.
I've given up on the public demanding 4.2 mHz luminance bandwidth for
now (but, yessirreee, they'll buy HDTV.)

     WRONG. There are 10 colour television systems in the world today:

     System      Luma BW    Chroma F-Sc     Countrie(s)

     "A"            ?           no          England       405 lines, obsolete

     Note that PAL-M uses the nominal values of colour subcarrier and
H scan/V scan (15750 Hz H, 60.00 Hz V) rather than the RCA "adjusted"
values in American NTSC.  Presumably, this was done to encourage a local
TV industry in Brasil??

The old 405 line B&W service has been taken out of service.  It was kept alive
until a majority of Great Britain was covered by the 625 line service.

I believe last year was the last year of 405 line.

Yes, the two color schemes are different.  The results that I have gotton
from the tapes I had converted are indeed just fine.  If I had my druthers,
I would rather watch PAL stuff on PAL equipment.  But, that makes it hard
to make copies.  I have had VHS PAL converted to 3/4" Umatic NTSC for less
than $175/2hr.  It was also done on a Digital frame-store converter.
The price: $80/hr.  This was a little private operation that was not big
company run and he is not out to make millions.

The Sony 3/4" decks that I have at home don't have any trouble locking onto
the output of any of the VHS tapes I have recorded.  I prefer to record them
on 3/4" first.  But sometimes something goes wrong (me) and I have to use
the VHS backup tape.

Sure, I'll buy HDTV.  It is the only standard (or hope to be standard) that is
wide screen and looks like it will have digital recorders from the beginning.

If you would like I could find out the exact model number of the converter
that he is using.

But, the proof is on the pudding.  I have 13 45 minute tapes that were
converted from VHS PAL to 3/4", like I said, that are some of the best
copies that I have seen, from VHS PAL.  There aren't any vertical problems.
I guess I shouldn't say that.  A couple of times the picture would jerk.
Why, cause I saw that the original master tape had a problem in it.
The digital converter just gave a minor hick-up and went on converting.
No sync loss, etc.  But, a couple of times out of 13 45 minute tapes is
excellent.  None of this vertical roll that the other person said would
happen.

The only problems that I had with the tapes was with the 3/4" tape.
It tended to lose tracking around the vertical sync, causing the recorder,
when editing, to lose sync on the copy.  I have a NTSC sync generator chip
that I put together years ago, but when connected to the Sony recorder,
wouldn't work.  Well, after enough of this problem (after all of the
editing was finished) I decided to open the Sony deck and find out why
the chip wouldn't work.  As it turned out, the input circuit loaded down
the TTL signal that I was supplying it, so that it couldn't trip the
internal circuitry.  With that fixed, I don't have to worry about bad
tape messing up the recorder.  I digress, but the main point is that
you shouldn't put down digital converters until you have seen them all.
In your job, you probably have seen most of them.  Also, if you were to
see these tapes, you would probably find something wrong with them.
But, for the original poster, a tape converted by my source would
probably work out just fine, which was what he was after.  I think that
the person who told the poster that he would have lots of problems was
indeed full of BS.

In your job, you are looking for perfection.  I too would love perfect
copies.  I would love to spend $250,000 for a full 1"C editing suite,
but don't have the money, so I stick with 3/4" for editing.  I would
love to have my mother-in-law have 3/4" equipment to record stuff for
me (in England), but that is out the question too.  I work with what I
have and that is all the original poster wanted to do.

I feel that he was scared off for no real reason.  True, the results
will not look as good as if it was recorded on VHS PAL, but it won't
be as bad as the guy told the poster.

I think that I have said enough.

In 1983 I was married in Scotland, and had my wedding videotaped. The UK
uses PAL, so when I got back here I had to find a way to get it translated.
I finally had it done somewhere in New Jersey - I can't remember where, but
I got the name of the place from an ad in some Video magazine I found at
the local B. Dalton's.
	If I recall correctly, the price was something like $100-$120 for
the 60-minute tape (they supplied the new tape). I had it done VHS to VHS,
but I don't suppose there should be any problem going to Beta. The quality
was excellent and it was done quickly (about 1 week through the mail). There
was a little degradation, but that's to be expected when dubbing any tape.

That's the old 405 line B&W system.  The first TV system in the
world.  Broadcasts started in 1936 from Ally Pally (Alexandria Palace)
in North London.  It has been phased out.  When colour was widely introduced
in 1968 plans were to leave the old transmitters running for (I think)
25 years to let all the old televisions die out.  I think they
actually pulled the plug last year because they decided that all
the old sets had finally died.

The scanning stardards differ too.  This would affect monochrome as well as
color.

Sorry, that won't work either.  On VHS machines, the actual rrecording speed
is even different.  Europes highest speed is about halfway between our SP
and LP speeds.  B&W would work if the speeds were the same.  I don't know what
the Beta machines do in Europe, so I can't talk about them.

No there are several standards, and several incompatable national versions
of those, the rumor is that the Swiss have multistandard TV's so they can
watch programs in German and French on the same set.  I'd just say TV
standards are all indo-european in root...

Only because your friends happen to have NTSC (never twice the same color)
decks to play them on, or they have a multi-standard deck. If you ask them
to make tapes from local TV and send them back, you'll run into trouble.
Conversion is possible but costs upwards of $100...

	Yes, there are tv's and vcr's available that support all three
systems(plus a voltage range of 110 - 240V). Sony has models for both.
I have also seen a Panasonic multi-system vcr.
Each should cost about $800-$1000 approx. I have come across
people from Asia/Europe staying temporarily for a couple of years in
North America buying these systems so that they can carry tapes from here
when they go back or vice versa.

It's not a rumor, it's true that you can buy in Switzerland TV sets that
would work for PAL(german standard) and SECAM (french standard). I think
it's due to our special situation in the middle of Europe.

   I have a question which relates to this matter of Euro-American VCR
operations.  I will be in England for several months this year; I am
taking a "camcorder" with me which doubles as a VCR w/out a tuner.
Is it possible to dub from an English VCR to one designed for the USA
market?  I have heard that it may not be.  If this is so, why?  I
would appreciate a reply.  Thanks.

hrs@homxb.UUCP (H.SILBIGER) (02/05/86)

While there are three basic TV standards in the world, NTSC (Never
Twice the Same Color), PAL and SECAM, there are many variations on these
in different countries, and the total is about 12!

Many VCR's available in Europe  are multisystem. These are usually
made in Japan, where they are also available.  Ihave also seen them
in some New York stores.

I read that the new digital TV set have conversion programming
built in, which doesn't necessarily mean it will be accessible here.

It seems probable that the new high-definition TV standard will
be uniform around the world.
