Video Monitors and Televisions
got you baffled?
Did you know that all
13" or larger TVs and monitor/receivers manufactured since
July 1, 1993 have closed-caption circuitry built-in? Since that
time, we have been made aware of a few confusing issues concerning
closed captioning. Strangely enough, some of the most serious
problems have involved customers that never use the feature.
Closed captioning provides
important benefits primarily for individuals with hearing disabilities
by displaying the audio portion of a television signal as printed
words on the television screen. Closed captions are hidden as
data within the television signal and they must be decoded to
be displayed on your TV screen.
are problems that can occur on closed-caption equipped sets
My television has suddenly started displaying a black box that
covers almost the entire picture, allowing only the edges to be
seen. This will occur if one of the closed-caption text modes
has been inadvertently turned on. This problem can be most annoying
since it occurs only intermittently. The box appears only if the
station you are tuned to is broadcasting closed-caption information.
It will disappear on programs that are not closed-captioned. To
fix it, youll need to turn closed-captioning off.
Help! Words are appearing
on my TV... but not all the time. This just means that the closed
captioning feature of your new TV is turned on (which is easy
to do accidentally on some sets). The words appear only during
closed-captioned broadcasts. You need to turn closed-captioning
How the heck do I turn
off closed-captioning? I wish there was a simple answer to this
one. All televisions enable/disable captioning in a different
way, so youll need to dig out that owners manual.
Generally, you must use the remote and you will find one of three
things: a closed-caption button, a display button that turns captioning
on and off, a menu button that will bring up an on-screen menu.
Can I record closed-captioning on my VCR? Yes! It doesnt
even matter how old your VCR is. As a matter of fact, tapes you
made before you had a closed-caption capable set will now display
captions on your new set (assuming the recorded material was originally
closed-captioned.) Closed captioning information is hidden in
the TV signal and your VCR cant help but record it. Remember,
however, that you still must play the tape back on a TV that has
built-in closed-caption decoding to see the captions.
I have a tape that
is closed-captioned and need to duplicate it. Will the duplicate
still be closed-captioned? Yes, except that professionally made
duplicates, or duplicates made on editing equipment could wipe
out the hidden closed-captioning if the process uses a time base
corrector, processing amplifier or digital video effects generator.
How do you find out? Ask the person making the duplication or
have them make a short test dupe.
My new VCR will set
the time and date automatically, and I heard thats related
to closed-captioning. Is that true? Extended data services (XDS)
shares the hidden TV signal area with closed-captioning and will
provide some innovative features on your TV and VCR in the near
future. Automatic time setting is just the first of these new
