Abstract:
The present invention is to provide a method of efficiently detecting music scenes from television broadcasts.A music-segment detection method according to the present invention includes a data input step of inputting data including an audio and video signals; a plurality of candidate-music-segment detection steps of detecting candidate music-segments from the audio signal based on criteria different from each other; and a music-segment detection step of detecting a music segment based on the plurality of detected candidate music-segments. Thereby, high detection accuracy can be ensured for a wide variety of music with various tones, such as rock, popular ballad, and classic.
