The broadcaster or program producer uses the CPC-VChip software to insert V-Chip ratings onto line 21 of the video using a closed caption encoder. The software can also insert other information such as the program name, station ID, etc.

When a home viewer watches a program with V-Chip information, the V-Chip in their television reads the V-Chip rating information, and either displays the program with the rating on the screen; or blocks out the program if the V-Chip rating exceeds the rating the home television set is programmed to allow.

Since many television sets do not have V-Chips, the software is also capable of simultaneously sending out program rating information as a viewable icon.
