SIGNAL RECORDING/REPRODUCING APPARATUS, SIGNAL RECORDING/REPRODUCING METHOD, SIGNAL REPRODUCING APPARATUS, SIGNAL REPRODUCING METHOD, AND PROGRAM

摘要

This invention is a signal recording/reproducing apparatus (1) for searching for a reproduction position desired by a user from a recorded video signal and/or audio signal and reproducing the signal. The apparatus has a feature vector generating unit (30). When recording a video signal/audio signal, the feature vector generating unit (30) generates a feature vector characterizing the video signal and/or audio signal and also records this feature vector to a recording unit (10). When the recorded video signal/audio signal is reproduced, a registration unit (40) registers feature vectors near a position designated by the user, as bookmarks. When the user designates one of the bookmarks, a coincidence detecting unit (60) searches for a coincident position on the basis of the feature vector of the bookmark and the recorded feature vector, and a reproducing unit (20) starts reproduction of the video signal and/or audio signal at a reproduction position set by a reproduction point setting unit (70) on the basis of the coincident position.
