Closed captioning
is a process
which converts
the audio portion of a television
program
into written
words which then
appear
as subtitles
on the television
screen.
Closed
captions
allow viewers
to read the dialogue
and narration
of
television
programs.
Using Closed Captions
Captions
are the subtitles
of the dialogue
and narration
of television
programs.
For
prerecorded
programs,
program
dialogue
can be arranged
into captions
in advance.
Its possible to caption
a live program
by using a process
called real-time
captioning,
which creates
captions
instantly.
Real-time
captioning
is normally
done by
professional
reporters
using a machine
shorthand
system
and computer
for transla-
tion into English.
Captioning
is an effective
system
for the hearing-impaired,
and it can also aid in
teaching
language
skills.

Caption Tips
• Not all TV broadcasts
include closed caption
signals.
• Sometimes
TV stations
broadcast
four different
caption
signals on the same channel.
By selecting
From
CC 1 to CC 4,
you can choose
which signal you view. CC 1 is usually the signal with the captions,
while Another
mode might show
demonstration
or programming
information.
• Your TV might not receive
caption
signals normally
in the following
situations.
1. Poor reception
conditions
are encountered:
IGNITION:
Picture may flutter, drift, suffer from black spots, or horizontal
streaking.
Usually caused
by interference
from automobile
ignition systems,
neon lamps, electrical
drills, and other
electrical
appliances.
GHOSTS:
Ghosts are caused
when the TV signal splits and follows
two paths. One is the direct path
and the other is reflected
off tall buildings,
hills or other objects.
Changing
the direction
or position
of the antenna
may improve
reception.
SNOW:
If your
receiver
is located
at the weak, fringe area of a TV signal,
your picture
may be
marred by small dots. It may be necessary
to install a special antenna
to improve
the
picture.
2. An old, bad, or illegally recorded
tape is being played.
3. Strong,
random signals from a car or airplane
interfere
with the TV signal.
4. The signal from the antenna
is weak.
5. The program
wasn't captioned
when it was produced,
transmitted,
or taped.
