TV Guardian

You know how all those movies are mostly OK except for all the stupid swearing or blasphemies that are almost compulsory? Well there is an option here in the US called TV Guardian. It tracks the teletext track on the movie (either TV, DVD or Video) and when an offending phrase occurs, it mutes the sound and shows alternate text on the screen. It replaces the phrase and not just the word. It must use a pretty impressive software algorithm to determine phrases and is normally quite accurate. There are a number of levels of protection, but the replacements are quite humorous. Sony now makes VCR and DVD players with the device as part of the unit.
