Abstract
Apparatus and method for sending and receiving subscriber video game computer data over a broadcast medium for use with video game players and which includes microprocessor controlled transmitter and receiver systems. The receiver system retrieves, demodulates, screens and selects computer data according to subscriber input. A receiver microprocessor signals a video game player to choose from a selection of games placed into a memory. The receiver microprocessor regains control of the memory and regulates flow of selected computer data to the memory. After checking for authorized use, the receiver microprocessor allows control of memory containing video game code to transfer to the video game player. The transmitter system stores, codes, and transmits the computer data over a public broadcast system.
