Closed caption function
Closed captioning is a process which converts the audio portion of a television program into written words which
then appear on the television screen in a form similar to subtitles. Closed captions allow viewers to read the dia-
logue and narration of television programs.

Captions are the subtitles of the dialogue and narration of televi-
sion programs. For prerecorded programs, program dialogue can
be arranged into captions in advance. It’s 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 translation into English.
Captioning is an effective system for the hearing-impaired, and it
can also aid in teaching language skills.

Your TV might not receive caption signals normally in the following situations.
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.
An old, bad, or illegally recorded tape is played.
Strong, random signals from a car or airplane interfere with the TV signal.
The signal from the antenna is weak.
