PURPOSE:To attain filing the picture information with aural captions with a simple constitution by recording continuously plural pieces of picture information, allotting and recording the audio information corresponding to those picture information to audio channels and having equal recording sections between the picture information and sound information. CONSTITUTION:When two audio channels CH are used in addition to a video channel CH, the video segment information Va, b, c... correspond to audio segment information Aa, b, c... respectively. In this case, the coincidence is secured between start points or finish points of segments [diagrams (1) and (2)]. A recording device gives the FM processing to the audio carrier at CH-1 by information Aa, b, c... and at CH-2 by information Ab, d, f... respectively. The video information is continuously supplied to an adder 3 and undergoes the conversion of frequency together with an identification code signal. The identification code identifies the audio CH containing the audio information corresponding to each video information at the reproduction side. These FM waves are added together and turned into recording signals. Both video information Va and audio information Aa are edited previously and fed to each modulator so that the real times are arrayed as shown by (1) or (2) between both types of information. |
