Abstract
A pay per use system allows the broadcast of television, videotext, and videogame programming all in the same system. The programming is broadcast in scrambled form with a broadcast signal imbedded in the program broadcast. The receiving station decoder has an internal code assigned to it plus is provided with an external code contained in a removable memory module from which it can generate signals to descramble the input program content. Television programming is viewed directly on a television screen while videotext and videogame programming are loaded onto a remote memory unit specifically adapted to interfit and mate to economical home computers specifically intended for videogames. The routing of the program, either to the television or to the remote memory unit is controlled by information in the broadcast code imbedded in the broadcast itself.
