According to

TVG® Technology is patented technology that detects foul words and mutes them. It works by monitoring the hidden closed-caption text and comparing each word against a dictionary of more than 150 offensive words and phrases. When a foul word or phrase is detected, TVG® automatically mutes the offensive language. A profanity-free version of the phrase is displayed during the mute.

You can buy this as an external box or several DVD players come with it built-in.
