Full description not available yet. Now de-funct pay-per-view version of DVD-Video standard developed by Circuit City, an American consumer electronics retailer.
System was developed to compete against DVD-Video format. Each movie disc had to be activated and each playback worked pretty much like a movie rental -- the player "dialed" to CircuitCity's servers when movie was being watched and checked if user had any "credits" left to watch the movie. If not, device would allow user to purchase more credits to watch the movie.
