PURPOSE:To switch easily modes of plural reproducers by constituting a selective transmission means for reproduction signal of a selection means to obtain signals of plural channels and a switch means for these signals and also using a controller which switches the modes of those reproducers for each channel. CONSTITUTION:The reproduction video signals sent from VTR81-84 are selected by a selection means 41 and supplied individually to either one of output terminals 42A-42D. The video signals of channels A-D given from terminals 42A- 42D are switched by a switch means 43 which is controlled by a microcomputer 14. Then the reproduction video signal given from a selected VTR is delivered to an output terminal 43' and supplied to a broadcast device. A transmission list is produced by means of the computer 14 and printed on the paper. This list is then stored to a memory means 25 of the computer 14 and also read out to be projected on the screen of a monitor picture receiver 14M.
