Abstract

PURPOSE:To double the recording time by reproducing at least once for a prescribed unit period signal among plural video signals and reproducing selectively one of plural sound signals simultaneously. CONSTITUTION:An output of a switching signal generating circuit 40 is fed to a video signal delay circuit 38 as a write inhibition command signal and the memory storage content in the video signal delay circuit 38 is rewritten for alternate one field and the video signal A1 of the video/sound signal source is written, for example, in a memory and read out and outputted. Then the write of a video signal B2 of other video/sound signal source inputted succeedingly is inhibited and the video signal A1 is read again and a video signal A3 inputted in succession to the signal B2 is written and read out simultaneously the same as the video signal A1. In repeating the operation above, only the video signal of the 1st video/sound signal source is supplied to the video output terminal 42 and the reproduced picture by the video signal is obtained. Thus, the recording time is doubled.
