Hello.
Does anyone know if it is possible to view closed caption characters without 
any caption-capable video playor or laser-disc player? 
I am not interested in viewing caption characters from network TV. I only want
it from video and laser discs. I think it may be possible by putting some independent
caption decoder within the connection of the TV and the video player. 
Is this right?

Thanks in advance,

Wongyu Cho

I need to find a way to convert RF signals from a coax line to baseband
A/v (preferably stereo).  The RF signal will already be set at channel 3
freq (ie the RF is coming out of a cable box and into a monitor). I know
that all VCRs have this capability, but I need to do this without an
additional VCR.

Also, is there a way to assimilate the baseband signal back into RF in MTS?

Please respond via email

The channel width for a broadcast FM station IS 200KHZ YES.  The bandwidth
that the actual station uses is considerably less.  Notice I said ABOUT
100KHZ.  100 khz would be able to contain a standard stereo fm broadcast
signal.  Of course, if you add on the two allowable SCA channels, it would
require more.  Since the original poster was mentioning the DMX over a
cable system, I felt it not necessarily important to mention the channel
width of an over the air signal so I only mentioned what the width of
the actual signal is.  I admit, I did use the term channel in the earlier
statement and maybe that was my mistake.

Is there any way to get rid of the 'BLUE' screen on my VCR.
(ie. the one that replaces the normal black+white 'snow.'  I can't use my
universal descrambler with it because of this 'feature.'  Any help would be
greatly appreciated.  Also, if this cannot be hacked out (I have heard there is 
a way to bypass a chip to get rid of the 'blue' effect.)  Where can I get a
relatively good (read: CHEAP) tuner???  Also, I am getting my descrambler for
 $60 un-assembled.  Is this a good deal, or should I look somewhere else???


BTW. this would probably help:  I have a Hitachi VCR (can give the model # if 
you have a specific hack....)  I appreciate it...

My mother lives in Lake Arrowhead, CA and is serviced (and how) by
Falcon Cable. For Christmas I thought it would be a nice thing to do
by eliminating some of the extraneous remotes around her house and get
her that pre-programmed remote from RCA. It works very well with her
RCA TV and Scientific Atlantic cable box. The remote for this cable
box was costing her $5/month. When she went to return it, they asked
whether she needed any remote access at all. She replied that she had
this new remote so she didn't need their remote. But since she needed
SOME remote access, she is being charged $2/month for "remote access".
For about $45/month she gets 21 channels (no ESPN, VH-1, MTV, CNBC,
Comedy channel, Sci-fi) and Showtime. She also doesn't get any MTS
signal. Unfortunately, since she is in the mountains, it's either this
or satelite.

I know what I wanna be when I grow up.... a cable operator.

Just venting some steam..  Thanks for listening.

Actually,Cablevision of Boston/Brookline did 180-degree turn regarding
carrying MTS signal for many of its channels couple weeks before X-Mas.
They now transmit local FOX affiliate in stereo(even with SAP).Also
music channels such as VH-1,TNN,CMT are now in full stereo sound. All
premium channels(HBO,HBO2,Cinemax,Showtime,Showtime2,MC,Bravo,AMC,etc) and
PPV channels were upgraded to have stereo sound as well. They also
completely eliminated any type of ghosting on all local broadcast channels
and the reception is the best it's ever been.I assume they actually wisely 
spent some of the subscriber-generated revenue to invest into some technology
to improve the quality of service.

Oh and they also quietely added Cartoon Network and Sci-Fi Channel to
its line-up last week without any announcement whatsoever. I have a feeling we're
in for a rate hike before Cable Act kicks in April.

Hi,

  After many requests for technical information on Video
  signals, I guess I better just post it..

  I found the best information of descrambling video in Radio
  Electronics..  Try back issues:

  February 1984
  February 1987
  May 1990
There are also some add's in Radio Electronics for books on
the subject.


I do have a question that someone out there may know the
answer too...

What effect would inverting the color burst do? (180 out of
phase)??  Would the colors be "Backward"?? making a light 
brown color a green color?? (Like with inverse video)?

I (Like some others I have spoken to) use the Universal
Descrambler on a non-scrambled chanell, and get good, accurate
color, but when a scrambled chanell is tuned in, the collors
are incorrect (Faces look green).  I have noticed that when
the vertical lock is NOT correct, the color's sometimes are
correct.  I have also noticed that if the polarity of the
video is reversed (Neg/pos) even though the images are
reversed, the color is correct.

My idea was to put the color burst 180 out of phase (This can
be done with the spare NAND and spare 4053 (to make it
selectable)) but before I try, I wanted to know if anyone out
there had any better ideas? or for some reason thinks I am not
on the right track.

Pretty much correct.

Most cable carriers just do broadband remodulation of "on air" signals, meaning
that in most cases MTS gets remodulated "for free."

However, in the case of satellite-fed services (e.g. HBO, TBS, Lifetime, etc.)
the stereo signal is encoded as (in most cases) discrete channels or (in some
cases) a matrix format.  Either way, a stereo signal comes off the satellite
but it is NOT in MTS format; rather the cable company needs a MTS encoder at
the head end for EACH channel it wants to pass along to subscribers in MTS
stereo.  This is why most cable companies only encode pay channels like HBO
and Showtime and very popular music channels like MTV and VH-1.  I've come
across painfully few cable carriers that bother to pass along stereo feeds for
most "basic" services (e.g. TBS, WGN, Lifetime, A&E, etc.)  Yet another reason
to get yourself a dish...

Rob,

I sympathize with your cable experience. But for the last 7 years while
living in Brighton(section of Boston) and adjacent town of Brookline I've
seen worse. Cablevision people would dismiss the reception problems as
"leaks",interference from local VHF stations,and old building structures.
No matter which section of town you were in,local PBS station(WGBH) was coming
in with more lines than you can find on a zebra. There were so much "grain"
on the upper channels(41-53) it reminded me of looking at sand on a beach.
Three weeks ago they finally got their asses in gear and solved all the reception,
picture problems,added stereo sound to a bunch of channels by,what I assume,
investing some money into the existing system. Maybe it was the fear of
the Cable Act or maybe Cablevision of Boston/Brookline came to their
senses and realized that a loyal subscriber deserves to be somewhat
satisfied with the product.

Is there an easier way?

Also, do these units also work for pay per view channels and how

I picked up a Unika VC-140 and it is a nice unit.  I'm not sure if
they are still made (or even the real name or address of the company
that made them), but they are a 140 channel converter with RF (channel
3 or 4) and baseband video, and mono audio and multiplex...too bad
it does not have MTS built in..

Remote control does channel with "flashback", up/down or direct
tuning, volume control, fine tuning and some other programming like
parental control and such.  Not having the manual, I'm not sure of
all the posibilities but it works quite well, and the video out is
much less processed than most VCR's...and so more useful for
other descrablers and such.  I found it used from a fellow on the
net for $30 with the remote.

Closed captioning is carried on Line 21 of the vertical blanking interval.
Sears (a department store) carries standalone decoders, however what you need
is one that has a video input.  I don't know if theirs do or not.  It should
be technically possible, but I suspect most caption decoder makers would 
assume that people are receiving at RF and not include video.
I believe that the FCC has recently required closed caption decoders to be
built into TV's starting somewhere between 93-95.

Hmm, that's surprising.  Do _any_ channels (eg. from satellite) come in
stereo?

When I found that even Cinemax (which we're getting for a `free' sample
month) didn't come in in stereo,  a plausible model occured to me.

_All_ our local stations come in on stereo, _none_ of the cable stations
do.  I'm assuming that whatever means our cableco uses to get the
signals for the local stations (apparently not directly over the air, at
least I've never noticed bad signal from weather) involves only minimal,
straightforward modulation.  Then the mts sideband (or whatever you want
to call it) gets carried along and de/re-modulated `for free', without the 
cableco having to do anything extra to send it out to us.
  The stations coming in from satellite presumably have a more involved
modulation/encoding so that the cable co has to make a concious effort
(and investment!) to decode the stereo and insert the mts signal.
In which case, they haven't.

[Yo experts; Is this a reasonable model of what goes on ?]

I asked the cableco, who said they would need to add more equipment and
it was a relatively low priority item for them at this time.  Apparently
few people do complain about it.  How much does it cost to `upgrade' a
channel's satellite reciever to decode & retransmit the stereo?

Anyhow, when my month's free sample is up, part of my reply will be "...
and I sure as @!)#*!@) aint gonna pay $x for cinemax without even
stereo!"

	I ordered cable last week from Continental in Cambridge, MA.  It was
SO bad, I cancelled it the next day.  We also have an antenna on our roof, and
the networks came in MUCH better with that.  It also seemed like the cable audio
was not stereo.  I only wanted cable for CNN and maybe the Discovery Channel,
but those were scrambled.  I did not buy a new cable-ready TV to have to use
their piece-of crap wood-grained cable box with its seperate remote-control.
What if I had a VCR and wanted the tuner to change cable channels for taping?
Don't mention VCR Plus because I do not need a kludge to send IR signals to
my cable box.

The cable manual describes the box as being a "feature" because your TV does not
need to be cable ready!  What a joke.  If they really need to raise basic rates
to get passable quality, then let them do it -- but my guess is that the rate is
high enough and they don't improve quality because they don't care or know the
difference.  Does no one else care?  Aren't their a lot of people with good
