Abstract

A personal computer is used to assist in the selection of television programs to be recorded at future times and to control a video tape recorder to implement the selected recordings. An application program allows the computer to receive data representing a schedule of future programs. The operator can perform data base operations on the data to obtain listings of programs of particular interest. A program to be recorded is selected by moving a cursor into position with the display of the program listing on the computer. An output device generates infrared signals to control the video tape recorder and a cable box to tune and record a selected program.
