Patent ID: 8682132

Claim:
A music-segment detection method comprising: inputting data including an audio signal and a video signal; detecting a first candidate music-segment, based on a frequency characteristic of the audio signal; detecting a second candidate-music-segment, based on a difference in a plurality of audio channels of the audio signal; detecting a scene change point in the data; extracting a first music-segment including a start time of the second candidate-music-segment and an end time of the second candidate-music-segment, the start time of the second candidate-music-segment being detected around a start time of the first candidate-music-segment, the end time of the second candidate-music-segment being detected around an end time of the first candidate-music-segment; and determining a second music-segment by correcting a start time of the first music-segment, based on the scene change point existing around the start time of the first music-segment, and an end time of the first music-segment, based on the scene change point existing around the end time of the first music-segment.
