An automatic multiple channel programming and video camera control system is disclosed in which, while the camera operator is operating the video camera system, the control signals generated by the operator are converted to a unique plurality of signals for recordation on a mass storage media, such a video tape recorder. By the use of two or more dual tone multi-frequency circuits having different crystal oscillator frequencies in both the programming and decoder circuits, and causing the DTMF circuits in the programming circuit to provide their outputs as 1/20th of a second alternating pulses, multiple channels of control are generated for recordation on a mass storage medium, for example, a video tape recorder. In that manner, two simultaneous camera control or other functions can be performed at the same time. On playback of the mass storage medium, the recorded signals are reproduced, decoded and used to provide automatic control of the video camera system and auxiliary functions. A modified video tape recorder may be used in which, during playback of the programmed signals, the video image is viewed by the selected video camera are recorded on the video track portion of the magnetic tape.
