PURPOSE:To simply perform the assembling edition of only audio signal through the running of tape once, by supplying an audio signal and a synchronizing signal to an editing VTR. CONSTITUTION:Video signals SB1-SBn reproduced from n sets of playback VTRs 21-2n and audio signals Sb1-Sbn from them are outputted. One of the video signals SB1-SBn and the audio signals Sb1-Sbn is selected, by switching contacts a1-an through the switching signal programmed in a microcomputer 6 in advance with switch circuits 3, 4. After a black video signal SBK is applied to the selected video signal, the result is applied to rotating heads 14, 15 through a recording amplifier 13. On the other hand, the audio signal is applied to an audio head 10 through a recording amplifier 9. |
