Abstract
A video recording system employs an editing device to communicate schedules of instructions to a videotape recorder control system which, in turn, communicates selected ones of the instructions from the schedules to a time-base corrector so that the time-base corrector automatically controls and adjusts video signal parameters at the output of the videotape recorder in accordance with an appropriate one of the schedules. Operation of the system includes the steps of storing schedules of instructions in the editing device, communicating the schedules of instructions to a videotape recorder control system connected to a time-base corrector, storing time lines of the instructions in the videotape recorder control system, and operating the time-base corrector to manipulate video signal information at the output of a recorder mechanism according to the time line schedules.
