ABSTRACT:
A recording/reproduction apparatus that effectively and efficiently utilizes a large-quantity information signal recorded onto a recording medium and efficiently utilizing the recording medium for recording the information signal. In a process to record a video signal onto the recording medium, a video classification process unit employed in the recording/reproduction apparatus recognizes similar pictures of the video signal, classifies pictures of the signal into similar-picture segments each including similar pictures and classifies the similar-picture segments into groups each including similar-picture segments resembling each other. Then, the recording/reproduction apparatus displays a picture as a thumbnail picture for each of the similar-picture segments on a classification display unit.
