Abstract

A system and methods for the dynamic generation of playlists to a user are provided. In connection with a system that convergently merges perceptual and digital signal processing analysis of media entities for purposes of classifying the media entities, various means are provided to a user for automatically generating playlists of closely related and/or similarly situated media entities for distribution to participating users. Techniques for providing a dynamic recommendation engine and techniques for rating media entities are also included. In an illustrative implementation, the playlists may be generated and stored allowing for user persistence from experience to experience.

Claims

1. A method for dynamically generating a playlist of media entities comprising:

analyzing media content to determine the characteristics inherent within at least one of a desired plurality of media entities, wherein the media content characteristics comprise any of tempo, sonic, melodic movement, or musical consonance, wherein the media content characteristics are determined by human classification and digital signal processing classification, wherein digital signal processing comprises sampling the media content and objectively measuring a quantitative value of the media content, wherein the media content is a song;

generating the playlist of media entities based on the media content characteristics, wherein the media entities are audio files; and

distributing the generated playlist of media entities over a network.

2. The method of claim 1, further comprising maintaining a set of playlist characteristics, wherein generating the playlist of media entities comprises filtering the media content characteristics based on the playlist characteristics.

3. The method of claim 1, further comprising defining playlist characteristics, wherein generating the playlist of media entities is based on the playlist characteristics and the media content characteristics.

4. The method of claim 1, further comprising weighting the media content characteristics.

5. The method of claim 1, further comprising filtering the media content characteristics according to predefined restrictions.

6. The method of claim 1, further comprising receiving a request to generate the playlist of media entities.

7. The method of claim 6, wherein the request comprises parameters defining the scope of the requested playlist of media entities.

8. A computer readable medium bearing computer executable instructions for carrying out the method of claim 1.

9. A modulated data signal carrying computer executable instructions for carrying out the method of claim 1.

10. A computing device comprising first means and second means for carrying out each of the steps of the method of claim 1.
