TVGuardian monitors the hidden closed-caption text in the background while you watch TV. Each word is checked against a dictionary of more than 150 offensive words and phrases. When a foul word or phrase is detected, the TVGuardian automatically mutes the offensive language. A profanity-free version of the phrase is displayed during the mute (the LT version does not display the profanity-free phrase on the screen).
For example, "Get the F- out of here!" would be muted and "Get out of here!" would be displayed during the mute, or, in the Strict setting, “Move your A#$!” would be muted and “Move your tail!” would be displayed during the mute. Then the text would be erased, the sound would be turned back on, and you would continue watching as usual. You won’t miss a thing – except the offensive language, of course.
TVGuardian has multiple filter settings, include: Strict, Moderate, Tolerant and other settings to fine tune your experience.
