Problems with Closed Caption Feature
• Closed captioning production companies may broadcast pro-
grams without correcting the misspelling in a live broadcast.
• Captions that are delayed a few seconds behind the actual dialogue
are common for live broadcasts. Most captioning production compa-
nies can display a dialogue to a maximum of 220 words per minute. If
a dialogue exceeds that rate, selective editing is used to ensure that
the captions remain up-to-date with the current TV screen dialogue.
• Interference from buildings or weather conditions may cause
captioning to be incomplete.
• Broadcasting station may shorten the program to insert adver-
tisement. The closed caption decoder cannot read the informa-
tion of the shortened program.
• The videotape may be illegally copied, or the caption signal
might not have been read during copying.
• “Text” mode is selected for caption. Select “CC1”, “CC2”, “CC3”,
“CC4” or “Off”.

logue.
