<p>An automatic multiple channel programming and video camera control system (10, 12, 14, 16, 20, 22) is disclosed in which, during operating of the video camera system (10, 20, 22), generated control signals are converted to a unique plurality of signals for recordation on a mass storage media, by a video tape recorder (14). Using two or more dual tone multi-frequency circuits (112) having different crystal oscillator frequencies in both the programming (12) and decoder (16) circuits, and causing the DTMF circuits (112) in the programming circuit (12) to provide their outputs as 1/20th of a second alternating pulses, multiple channels of control are recorded on a magnetic tape. On playback, the decoded signals are used to provide two simultaneous camera control or other auxiliary functions. Use of a modified video tape recorder (12), during playback of the programmed signals, allows a video image viewed by the selected camera (22) to be recorded on the video track portion of the magnetic tape.</p> |
