In a progressive scan video production system with no 30Hz information dealing with progressive scan TV signals, phase of time code signals of 30Hz and video signals of the progressive scan TV system is locked. VTR 1 and VTR 2 of the progressive scan TV system are connected by a single coaxial cable, and progressive scan video signals are transmitted in a serial digital interlace format. In VTR 2, using time code signals multiplexed to serial digital interface signals, information corresponding 1/30 second is detected, field information is generated, video signals and time code signals are phase locked for recording and reproducing.
