Filed: 1984-04-05
Abstract: PURPOSE:To make it possible to execute the warming-up operation by obtaining a prerolling offset quantity on a basis of frame error information between a VTR for recording and a VTR for reproducing at a synchronous matching operation end time and performing prerolling by a quantity corrected by this obtained quantity. CONSTITUTION:Reproducing of a VTR1 for reproducing and a VTR2 for recording is started from the prerolling position, and the VTR2 for recording is synchronized with the VTR1 for reproducing. Positions of both VTRs are confirmed by a time code or the like after synchronous matching is completed, and the phase modifying work is executed if there is error between them. This error information is stored each time and is used for prerolling offset. With respect to the phase modifying work, the reproducing speed of one of the VTR1 for reproducing and the VTR2 for recording is increased or reduced to absorb error. The reproducing speed is restored to the normal speed after phase modification is completed, and the VTR2 for recording executes the synchronous matching work. Thus, the operability of editing between VTRs whose types are different from each other is improved.
