摘要

An apparatus for browsing video, comprising:feature data extractor (15) for extracting feature data from metadata recorded on a recording medium (2), on which segments corresponding to metadata, a video signal (78), or an audio signal (79) are recorded,either by a method for recording, comprising:recording an inputted video signal (78) or audio signal (79) on a predetermined recording medium (2);dividing the video signal (78) or audio signal (79) into predetermined segments (1201) to extract a feature from the video signal (78) or a feature from the audio signal (79) for each segment (1201);generating metadata including feature data corresponding to the features and start positions of the segments (1201); andupon the recording, recording the metadata on the recording medium (2) in association with the segments (1201);or by a method for recording comprising:recording an inputted video signal (78) or audio signal (79) on a predetermined recording medium (2);dividing the video signal (78) or audio signal (79) into predetermined segments (1201) to extract a feature from the video signal (78) or a feature from the audio signal (79) for each segment (1201);generating metadata including feature data corresponding to the features and start positions of the segments (1201);detecting a commercial segment (310a) included in the video signal (78) or audio signal (79) based on the video signal (78) or audio signal (79);modifying the feature data based on a result from detection of the commercial segment (130a) to generate the metadata; andrecording the metadata including the modified feature data on the recording medium in association with the segments (1201);the apparatus further comprising:a comparator (16) for performing comparison between a value corresponding to the feature data and a predetermined threshold;searcher (16) for searching the segments recorded on the recording medium for a segment that matches a result from the comparison; andreproducer (14,123,13) for reproducing video or audio corresponding to the segment retrieved by the searcher.
