How does the TVGuardian work?
TVGuardian uses the hidden closed caption signal to find profanity. The process consists of monitoring the closed captioned signal, each captioned word is checked against a dictionary of offensive words stored in the TVGuardian. If an offensive word is detected, the audio is muted for the sentence, the offensive word is removed from the closed captioned signal. A suitable word is substituted for the profanity, when appropriate, and the replacement sentence is displayed on the screen in text form. Example: In the movie Mrs. Doubtfire, “You bring home the ‘gd’ zoo,” would be silenced. The words, “You bring home the zoo,” would be displayed in closed-caption on the TV.
