Description

  The present invention relates to a dubbing apparatus and a dubbing method.

  A dubbing device that records a reproduction signal obtained by reproducing content recorded on a reproduction-side medium on a recording-side medium is put into practical use. A problem with such a dubbing apparatus is that no signal after the end of the content on the reproduction side medium is recorded on the recording side medium. In particular, when content recorded on a video tape is recorded on a recording medium, the video tape often causes a problem because reproduction is not automatically ended when the content ends.

  Therefore, conventionally, there has been considered an apparatus for performing dubbing so that a non-signal portion of a reproduction-side medium after the end of content is recorded as little as possible on a recording-side medium.

  For example, in Patent Document 1, a recording / reproducing apparatus determines whether a VCR reproduction signal is a non-signal or a presence signal while performing an operation of dubbing a VCR reproduction signal to a DVD. Information indicating that the non-recorded portion of the VCR playback signal is not recorded on the DVD by changing to the pause state, and the recording pause state continues for a predetermined time or the VCR playback control unit has changed from the playback state to the stop state. Is received, the recording state is changed from the recording suspended state to the stopped state, and the dubbing is stopped.

Further, in Patent Document 2, when the dubbing apparatus detects a no-signal period of a predetermined time or more and does not detect a subcode signal, it determines that the reproduction digital information signal is not supplied to the recording apparatus, and reproduces it. A configuration for stopping recording of a digital information signal reproduced by an apparatus on a recording medium by a recording apparatus is disclosed.
