Description

  The present invention relates to a technology of a playback apparatus that allows an operator to realize a free effect in an effect space such as a club.

  Along with the advancement of digital technology, a playback apparatus that can perform special playback similar to special playback using analog records (so-called scratch playback, etc.) on a CD (Compact Disc) has become common. This CD player is preferably used by a DJ (Disc Jockey) or the like, particularly in clubs, home parties and the like.

  Such a reproducing apparatus stores an audio signal reproduced from a CD, CD-R or the like in a buffer memory. This playback apparatus generally includes an analog record-like jog dial, and controls the reading speed and order of audio signals stored in the buffer memory in accordance with the forward and reverse speeds and rotations of the jog dial. By rotating the jog dial in the same manner as an analog record, an operator such as a DJ can generate sound effects such as a scratch sound similar to the case of using an analog record player.

  Furthermore, in recent years, with the spread of DVD (Digital Versatile Disc) accompanying the advancement of compression technology, it has become possible for individuals to easily obtain not only audio data but also video data. Under such circumstances, a signal processing device capable of special reproduction of both an audio signal and a video signal by an operation similar to that of the reproduction device has been developed (for example, see Patent Document 1). A person who operates such an audio signal and a video signal by using such a reproducing apparatus particularly in a club, a home party or the like is called VJ (Visual Jockey or Video Jockey).

  For example, a VJ or the like reproduces a DVD on which moving image content (video clip or the like) is recorded with the above-described reproducing apparatus, and performs a scratch operation with a jog dial using an operator's original technique. At this time, the playback device changes the playback direction and speed according to the direction and speed of the scratch operation, and outputs an audio signal and a video signal. The resulting audio and video can be viewed and changed as if an original video clip with completely different playback contents was played normally, as compared to when the prepared video content was played normally. It is served to a person (club guest, etc.)
