V - Chip
The V-chip is a technology that lets parents block television programming they don't want their children to watch. The V-Chip electronically reads television-programming ratings and allows parents to block programs they believe are unsuitable for their children. (Ratings appear in the corner of your television screen during the first 15 seconds of a program and in TV programming guides). This rating is encoded into the program, and the V-chip technology reads the encoded information and blocks shows accordingly. Using the remote control, parents can program the V-chip to block certain shows based on their ratings.
