SCAN VELOCITY MODULATION is a good thing?

[John Massachusetts Pigye]

I was at the local electronics store looking at the new televisions. I talked to the salesman and asked him about Scan Velocity Modulation and he
said that there's nothing wrong with it and he told me that If I tried to disable it I would void my warranty and
might even my homeowner's insurance (he must have been being naive).

I told him that ppl on USENET say that it's a bad thing and should be disabled. He told me that SVM is fine and that people on the internet have no lives and just spend all th eir time thinking up things to cry about.

Should I listen to this crackheads advice?

Velocity modulation is a Bad Thing. It makes text too "loud",
obscures detail, and results in an unnatural picture. For a more
photographic or film-like picture you DON'T want any sort of edge
enhancement like this. Faroudja processing is OK, it improves edges
without ringing or boosting detail whites; - and a slightly rising
frequency response can be useful. I turn Velocity Modulation off (in
the service menu if necessary) or clip the wire on every set I've had
with this "feature."

Is there a list of sets with this feature anywhere? Or is it generally
listed on the set or in the manual?

No. The guy obviously has no experience with it and is talking
about something that he knows nothing about. No warranties will
be voided as long as the disabling of VM only involves
configuration settings--possibly from a service menu (obviously
if hardware changes to the set are necessary to turn off VM, that
would void a warranty) I am no expert either but I do know the
following from personal experience:

1) Velocity Modulation is an artificial way of increasing
contrast along edges of verticle lines. Although complex in
function, the result effectively stretches dark areas and
shortens light ones which creates a distortion along edges that
is not in the original signal. For example, if you have a
perfectly proportioned "+" symbol on the screen, with VM turned
on, the vertical section will appear narrower than the
horizontal. However, there appears to be an increased contrast
along the vertical edges.

2) I have a Sony XBR 36" set. In all modes except "Movie" VM is
on (and can't be turned off). For all of these modes, you can't
get the sharpness down far enough to eliminate the ghosting
artifacts unless you turn the sharpness off completely, in which
case you lose much more definition than necessary (useful only
for watching broadcast stations with lots of "snow"). In the
Movie mode (VM off), it is very easy to adjust the sharpness for
best definition without the ghosting effect typical when the
sharpness is too high. I have gotten to the point that I can't
stand watching any of the other modes which is aggravating since
I'd like to have more than one mode available to me (e.g. a
subdued mode for watching at night with all the lights turned
off, etc.)


IMHO VM was added to sets for the same reason several have red
boost--simply to sell sets by what appears to be a very "sharp"
picture in the store (i.e., take a good attribute and magnify it
beyond normal). However, like anyone experienced in buying audio
equipment knows, the initial impression is often deceiving. A
bright sounding system may seem to have a lot of great "detail"
and yet when you get it home and listen for an hour or so, it
starts grating on your nerves and making your ears bleed as you
realize it's not balanced, there's too much hash, and no amount
of adjusting of tone controls can really get it fixed.

The picture produced with VM may be acceptable and even
desireable by many people. However,
a) The picture shows detail that is not in the signal and
b) Some people find the artificial high contrast edges offensive.

BTW, if you go back to that store, get a different salseman.

Hope this helps some.

The SVM settings are defeatable in the main user menu, and the user
instructions that come with the TV will even tell you how to disable it. (Or,
at least this is true with most sets that have SVM.) Since this is typically a
user-adjustable option, setting the SVM off will not void the warranty.

It seems like he's heard of it. That suprises me actually. Though he might

The question you should of asked the salesman is "What T.V.'s here have
Scan Velocity Modulation?" or "Does this T.V. with SVM have a user setting
to defeat it?". He said that "it was fine" because most consumers don't
even know what Scan Velocity Modulation is. It amazes me how many hours
people spend in front of the television each day yet don't even know how it
works inside. I've even heard stories of people thinking that an S-Video
cable is somehow another term for a high quality coax cable. I feel that
consumers need more electronic education, especially these days.

He's even heard of USENET, what do you think about that .

user has no need to know anything about what's inside.

Actually, Steve, you are making a generalization that is far from correct in
many cases. There are a variety of VM circuits that can have effects from
very good to awful. As far as rising frequency response, this can be a real
problem if the source is noisy, as can be seen on most Sony HD sets when
viewing crappy analog cable signals. The VM on the Sony sets is typical of
what you describe and looks pretty bad in most cases. The VM on the
Mitsubishi sets actually works pretty well on most images. One should
always experiment with the effects before deciding to enable/disable any
setting and not rely on vague generalizations.

[Jerry Greenberg]

The salesman does not know what he is talking about. I think he should
take a few valumes with a glass of Coka-Cola, go to bed, and see his
phsycirotrist in the morning.

Most of the sets have a feature to turn it off. In some models they
may call it under a slightly different name. In some of the Sony sets,
it is called "V" resolution or something like this. It does do some
enhancement, and some people like the effect. I myself turn this off.

What you're saying Leonard is that mild Velocity Modulation is better
than heavy Velocity Modulation. Well?? The fact is that Faroudja,
available in most good sets, is still the best way to harden edges. A
slightly rising frequency respnse will indeed increase noise, but it
can be used to give a bit more presence to a clean image.

What I am saying, Steve, is that generalizations are not helpful. Paying
attention to the effects of individual circuits on varying signals and
making educated decisions is a better idea than simply rejecting any
application of a very vaguely applied terminology. Just like a slightly
rising frequency response can be used to give more presence to a clean
image, SVM can do the same. In fact, the end result is to have a similar
effect. Either can be exaggerated.

Making sweeping statements like you did in the post that I responded to is
like saying "plasma displays are better" or brand x is better because it
uses x-inch CRTs.

Faroudja processing can be helpful, of course. Switchable SVM is important,
as well, just like knowing how to adjust your sharpness, brightness, and
contrast...

The point is that generalizations are usually only a starting point. There
is almost always more to the story.

No it certainly is not "true resolution". But it can to some degree
improve on the limitation in high frequency response at peak output that is
a limitation of CRT based systems, and in some cases result in a better
looking picture, as can other processing like Faroudja or frequency response
fiddling. It is useful to not reject any technology without understanding
it and observing its effects. If you don't like it turn it off, or buy a
set that allows the option.

Like I said, look at the Mitsubishi sets that have the option to switch SVM
in the user menu. Some things look better with it, some do not, but most
people will choose to use it rather than not. It mostly works pretty well.

I agree. I remember when the first RCAs back in the 80s offered "edge

this is done at the video level and there is no way defeat it.

I would say no, if you can set an option on your set and it voids your
warranty thats pure salesman bullshit. Sadly most times salesmen are not
burdened with any technical knowledge, if the set is any way decent you
should be able to play around with settings until it suits your tastes.

That's what I do. I do try to approach video kind of like audio. I would like
a neutral approach towards the performance of reproduction of the equipment
with as little "colorization" to the information as possible. Adding velocity
scan modulation only adds an unnecessary level of processing that I'd rather do
without.

I've observed it with many displays and it just doesn't look "film-like" with
DVDs. Plus, DVD is high resolution, but it does have mostly unnoticeable flaws
in the picture that end up being revealed and exaggerated with edge
enhancement, as well as obscuring fine details.

Regardless of what anyone may say, *I* think edge enhancement does some pretty
nasty things to the picture.

As for Mitsubishi, I wouldn't really go with them anymore. They don't seem to
make CRT direct view TVs anymore and their big screens, while okay, are no
match for a decent Hitachi model, just to name one.
Mitsubishi has also slipped considerably in terms of their Q.C., IMO. I just
don't trust them to build anything decent anymore. - Reinhart

Yes, exactly, I totally agree with you. No VM, no ringing please.
Maybe just the tiniest bit of coring to make the the response slightly
flatter at the high end.


I just can't stand it when someone dubs a tape for me and uses an
"enhancer" to "increase the resolution" (this is a quote of course!)
Meanwhile not only has the picture been made unwatchable but the sync
may have been distorted, so the picture tears etc.

the monitor is appropriate, and the monitor has flat response, thus
the monitor is showing what's on the source. Any sort of sharpening
or edging is to either cover a signal loss or to make the picture
appear sharper to the viewer. MAYBE a slight bit of coring can
compensate for scanning spot size, but that's only for very high
quality purposes. That's my generalization.

All my viewing is done on a Barco 21" or a Wega 32". No VM, the
response is measured as flat to the cathode, (Or matrix, there's
usually a test point) and a Leitch test generator is used for
calibration. Sources are Laser, DVD, Betacam, or DVcam. It's
remarkable how similar the picture is on the two completely and
dramatically different sets. The Wega is good enough for final edit
playback, though the geometry on these Sony sets suck. <g>
