It works through the captioning that runs through television programming, videos, and DVD's. PROTECTV works with both the audio as well as the written captions that are available. Every time an offensive word is spoken it is compared to a dictionary of over 400 words and phrases and if the word or phrase matches, it is deleted from the soundtrack and captioning. The viewer will experience a momentary gap in the audio and for viewers reading the captions, the undesirable written word is replaced by XXXX's.
what happens if the captioning has already filtered those words...?
