Set top boxes are computing devices used in conjunction with the TV.
 Applications include decoding cable, digital terrestrial, or satellite
 transmissions, allowing access to video on demand, and providing access
 to the Internet.

  Some set top boxes (STBs) are also Network Computers and provide
 access to the Internet as well as their usual functions, other STBs
 are not Network Computers.
