Method and apparatus for summarizing music content automatically

The present invention relates to a method for automatic summarization music content in a digital content management system and the device. The present invention comprising the steps of: extracting the audio characteristic values ​​from the compressed area of ​​the music data, the use of the extracted feature value of music information, by tracking the change point of segments (segment) in step with each segment the reconstructed to reconstruct a certain and clustering (clustering) taking a portion (fragment) of a length using a step and the segment selected by the similarity and repeatability between each of the measured segment of the measured similarity and repeatability between each segment generating a music content summaries providing music information automatically summarized method comprising. According to the present invention, it is possible to extract audio features from the compressed area provides a summary music automatically with improved speed applied to the summary music information, method and apparatus. Music, summary, changes, clustering, similarity and repeatability
