ABSTRACT:
A dubbing apparatus for dubbing signals in which recording information, such as a distinction between the field picture and the frame picture, the track number, the date of shooting, etc. is multiplexed with compound video signals of a still picture. Revising data is inputted for instructing the revision of recording information. A decoder decodes the recording information to be dubbed. New recording information is prepared on the basis of the revising data and the decoded recording information. An encoder encodes the new recording information, while a modulating circuit modulates the encoded recorded information. A frequency modulation circuit frequency modulates a video signal that is to be dubbed, while a synthesizing circuit multiplexes the modulated recording information and the video signal. The multiplexed signal is recorded on a recording medium, so that it is possible to revise recording information at the time of dubbing.
