Abstract

PURPOSE:To enable reproduction with good operating performance and without deterioration of video quality, by converting the character information which is desired to be superimposed on the playback picture of a VTR into an audio code signal, and recording it on audio channel in after recording mode. CONSTITUTION:In recording a character signal, first a VTR6 is reproduced and the mode is changed over to an after-recording-mode when the title, date are desired to be superimposed. When the character information preset with an insertion character designation circuit 7 is inputted to a signal conversion circuit 8, the character information is converted into an audio code signal and given to an audio code signal output terminal 9. The VTR6 is at the after-recording mode and the audio code signal only is recorded on an audio track from a VTR audio input terminal 10. At playback, the audio signal input is identified at a code signal discrimination circuit then separated into the audio signal and the audio code signal.
