ABSTRACT:
A television broadcast system using land lines is provided for real-time transmission of a viewer-chosen program at a viewer requested time to the requesting viewer's television receiver. The preferred method includes the steps of providing a collection of stored programs, communicating the requesting viewer's choice of a program chosen from the collection and a requested time for viewing the chosen program, selecting the chosen program from a collection, transmitting the chosen program at the requested time for viewing on the requesting viewer's receiver, and preventing intelligible viewing of the chosen program on other receivers.
