Abstract

PURPOSE:To enable to record the additional sound at the horizontal period succeeding to the horizontal period of the vertical blanking period detected in which audio is recorded. CONSTITUTION:In case of recording of additional audio, VTR is at reproducing mode. Further, the recording number of times pulse N obtained through the reproduction of audio in compressed recording is used as the clock pulse. Further, the preset data is taken as lH with the additional instruction. Futher, the count of the pulse N reaches lH+1, then the recording gate is made open. The one field's share of the audio to be recorded is compressed and it is recorded to the horizontal period of the lH+1-th. Thus, without losing the audio recorded, the additional audio can be recorded.
