V-Chip Technology can let parents block TV programming based upon particular ratings.

Complications

  • The V-chip exists only in TVs since January 2000
  • There is a significant education process (~80% of parents who have TVs with the V-chip are unaware of it). PINs are often forgotten.

Traps (Filters)

May be used to remove a particular channel, or multiple channels

Complications

  • Physically installed, any changes to customer's request requires a repeat visits from the installer.
  • S tandard inexpensive single channel traps are in lower frequency ranges
  • As the frequency increases, either the price of the trap increases or the performance decreases along with the quality of adjacent channels

  • If multiple channels are to be filtered, the signal quality can be greatly diminished
