Of course it's flawed - you are processing what orginates as an analog
signal in the digital domain with processing bandwidth limited by
current theories on video compression and current hardware 
technology. Video with a lot of motion is far more processing
intense than a "talking head" with a still background, and sooner or
later the hardware and algorithms will not be able to keep up well enough 
to prevent artifacts of the type seen from occuring. Things are
improving all the time, though. Maybe by the time of the next Olympics
the state of the art will have pushed these artifacts into the subliminal.

Subject:      Dish Alignment

        Thanks to Alan Larson I finally got my dish in the proper
position.  I put the pole back in plumb as it had been originally.
At this point I took signal readings on every sat I could get.  As
I later found out my original problem was that I was taking to few
signal readings 4 instead of a possible 8 or 9, these were put into
a database.  Since I don't know where or what a "pole star is" I
rotated the dish mount to the west.  More readings were taken.  I
then rotated the dish mount to the east, for more readings.  I
then plotted the siginal readings which indicated a crossing of readings
at about G5.  I then moved the dish west a touch and again more
signal readings.  At this point in time you must be thinking nut is
really stupid, what a jerk.  I only have the tv monitor to find out
the siginal strength, no fancy electronics stuff. After the siginals
no longer crossed, I moved the dish up and then down, more readings
were plotted.  I then peaked the dish as the plot indicated, for
the best signals possible, on all of the sats.

        Was my time wasted, NO!  I had taken signal readings from
the original location, where it had been aligned by the installer.
The highest signal before I moved the dish to it's new location,
and did the above alignment was 57, and the lowest 36.  Using the
same channels as originally checked my highest signal is 65, lowest
47.  My way of doing things might be odd but it WORKS.  My alignment
process only took two hours, thank goodness for computer plots.

                                                Thanks,

I noticed the exchange concerning artifacts seen on NTSC reproduction of
the Olympic feeds.  I had observed last week the test patterns for NBC's
27.5 W Intelsat feeds, so clearly there is no compression going on here.

As many have observed, the use of less than ideal PAL to NTSC converters
is probably the cause of the observed artifacts, but it may also be due
to the fact that at least some of the orginal feeds start life as
European HDTV signals.  Who knows how the signals get impaired when
converted to standard PAL and standard NTSC!

We bought the triplecast because my daughter is a horse-person, and they
promised 35+ hours of horse events.  So far they have preempted or slipped
every one in favor of things like gymnastics, which they show on free TV
anyway.  Calling NBC in New York gets me the information that "NBC has

Your are always going to degrade quality a little when copying a tape.
There are arguments on the net over which is the "better" formats,
and I've heard strong arugments for and against both.  But I think
probably the SVHS would be a better medium for editing on since the
physical tape is bigger, and the effective drop-out rates would be
less than on Hi8 tapes, assuming similar tape quality in both cases.
Dropouts are a fact of life too, just like new generation degradations.
The same size drop out on a SVHS tape will affect the picture a lot
less than the same size drop-out on a Hi8 tape.

Reply-To: B.King@ee.surrey.ac.uk
Distribution: world
Organization: The Internet

A colleague recently acquired a JVC HR-S4700U NTSC SuperVHS
deck on my behalf.  I've been rather annoyed in that I haven't
found a way of keeping the time counter on the VCR's display,
something I find bordering on the essential.  I have on-screen
messages switched off for obvious reasons when editing/copying.
At present, the display button will bring up the time counter
but the display reverts to showing the tape transport mode
after about 10 seconds.  Anyone know a solution to this?

As somebody not from the USA, there were a few pitfalls I
fell into... During setting of the time and date, I just
about remembered the non-progessive order of US-style dates,
but was very puzzled when the machine refused to accept the
time in 24 hour clock!  Also it was a few minutes before I
found and disabled the on-screen messages.  Other wise
apart from the hassles of transformers and the lack of a
SCART socket, the machine works very well indeed.  Certainly,
the JVC HR-S4700U seems to work perfectly on 50Hz 115V.

It was also interesting to compare the HR-S4700U with the
PAL version marketed in the UK (HR-S4700EK) - the most
noticable differences are the price (HR-S4700U = US$600,
HR-S4700EK = UK#699 - US$1300), the addition on the UK
version of manual audio record level control, SCART
socket, and 16:9 aspect ratio record ability.

I own a Sony GV-8 which is the type of unit you refer to (the Sony models are 
GV-8, GV-200, GV-300, GV-500).  And it is a great way to kill time when flying.

HOWEVER beware!  American Airlines will not let you use these devices in
flight.  They give an excuse they have not been tested (AA FORM T220 CPN
5616354).  United Airlines has _no_ problem with you using these devices.
Either American has exceptionally flaky aircraft in its fleet that require
special testing or this excuse is as phoney as a $3 bill.  They also ban PC's
with attached mice and track balls and certain electronic games.  What bugs me
about this is the phoney excuse. It would be very easy to test these devices
for RF and know quickly if they could cause a problem.  I strongly suspect that
there are other reasons such as making life easy for the flight attendents at
work here and they decided to play spin doctor on the reason.  Keep in mind
other airlines don't have this foolish restriction.  Keep in mind I am sure
Sony would have done the RF testing for them since they already have to do it 
for the FCC.  Please keep this in mind next time you are deciding which airline 
to support when buying a ticket.

As anyone with a newer camcorder can tell you, that "distortion" is simply the
result of using a high shutter speed on the video camera. The high shutter
speed is often used on fast moving objects (like race cars, tennis
balls, and the "dream team") to reduce motion blur that you see with slower
shutter speeds.

If you make a tape of this "distorted" video and then still frame
through it, you'll see very little motion blur even though the cars are
travelling around 200MPH (or whatever).

That's why you're seeing a strobing effect.

For those unfamiliar with the L1, it is the only interchangeable-lens
prosumer Hi8 camcorder made.  It is similar in layout to the Canon A1
and A1 digital.  To my knowledge, there are three lenses available for
the L1 - 8x, 15x, and a really neat 3x wide-angle zoom. It will also
take Canon EOS still camera lenses, but the field of view will be a
fraction of what it is in 35mm. It has a bit of weight to it and is 
held in front, not on the shoulder.  It has two channel AFM stereo, 
but to my knowledge no PCM stereo nor RC time code. I have seen images 
from the A1 digital and they are very good - for a single chip camera.  
The L1 is too heavy for the Steadicam JR, but haave have seen and tried
the A1 on the JR.

If I were in Eric's position, I would hold onto my A1 as a small "roving" 
camera and seriously consider a real professional Hi8 camera - the Sony 
EVW-300, the Toshiba TSC-100, or one of Toshiba's upcoming pro hi8 models
destined to hit the market in the next year.  These cameras go on the
shoulder and have interchangeable lenses - you can select from a multitude
of pro 1/2" format servo-zoom video lenses from several manufacturers.
and these camera have PCM stereo plus Hi8 frame code recording.  The
biggest plus is that they have three chips.

I am guessing that a fully-equipped L1 would go for close to $3000.
I expect that during the year, you'll be able to get a three-chip professional
hi8 camcorder for a little over $5,000.  True,it's double the price,
but the capability is more than double.  And you'd have a formidable
combo for professional coverage - the A1 for its size and lightness
advantage as a hideable or roving camera, and the EVW-300, TSC-100, or
other pro model for your master shots.

From my perspective, the 12.5 pound weight of a fully-loaded EVW-300
allows a lot of flexibility, compared to larger docking systems and
cable-connected camera-VCR combos.

You gotta be kidding, right?  No machine with that kind of capability is
going to be that cheap.  Your first price was closer.  Maybe a little high,
but better than $2k.  I only know of pro-decks with that ability, and then
if you are looking for a particular frame, then you need SMPTE time code,
which adds about $1k to the price (if not included are part of the deck).

Remote control power buttons when constantly pressed won't do anything (since
the TV assumes you haven't released the button yet).  When you walk in front of
the TV it breaks the signal and when you pass ythe TV the signal is regained, and 
the TV assumes the button was pushed again.   Are you're remote control buttons
