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 computer-readable medium storing computer-executable instructions for dynamically generating target playlists of media comprising:

defining underlying characteristics of said target playlists using human classification techniques and digital signal processing (DSP) techniques, said underlying characteristics representative of characteristics inherent of desired media;

generating media sets having said defined underlying characteristics;

merging said media sets according to predefined interactions between perceptual analysis and acoustic DSP analysis to generate said target playlists; and

distributing said generated target playlists to said user.

2. The computer-readable medium of claim 1, storing further computer-executable instructions for performing the step of weighting the media elements contained in said media sets according to at least one weighting randomization algorithm to generate said target playlists.

3. The computer-readable medium of claim 1, storing further computer-executable instructions for performing the step of filtering said target playlists according to predefined restrictions.

4. A system for dynamically generating target playlists of media comprising:

means for defining underlying characteristics of said target playlists using human classification techniques and digital signal processing (DSP) techniques, said underlying characteristics representative of characteristics inherent of desired media;

means for generating media sets having said defined underlying characteristics;

means for merging said media sets according to predefined interactions between perceptual analysis and acoustic DSP analysis to generate said target playlists; and

means for distributing said generated target playlists to said user.

5. The system of claim 4, further comprising means for weighting the media elements contained in said media sets according to at least one weighting randomization algorithm to generate said target playlists.

6. The system of claim 4, further comprising means for filtering said target playlists according to predefined restrictions.

7. A computer-readable medium storing computer-executable instructions for performing a method for matching a user'"'"'s musical preferences by dynamically generating at least one playlist in accordance with said user'"'"'s musical preferences, comprising:

providing a specific choice of user preferences in song content to a content provider;

mapping the specific choice of user preferences in a song analysis and matching system using a set of fundamental musical properties that captures the user'"'"'s preferences in song content using human classification techniques and digital signal processing (DSP) techniques;

scanning a database using the song analysis and matching system to find other songs that have a similar mapping of musical properties; and

generating at least one target playlist having media entities that have a similar mapping of musical properties by using predefined interactions between perceptual analysis and acoustic DSP analysis.

8. The computer-readable medium of claim 7, storing further computer-executable instructions for performing the step of distributing said generated target playlist to said user.

9. The computer-readable medium of claim 7, wherein said generating step further comprises the steps of:

categorizing media entities according to predefined categorization schemes by a music matching and analysis system responsive to instructions from a calling object to generate categorization data sets, said calling object instructions providing one or more characteristics of said media entities for use in categorization; and

merging said categorization data sets according to at least one weighted randomization algorithm to generate said target playlists.

10. The computer-readable medium of claim 9, storing further computer-executable instructions for performing the step of filtering said generated target playlists according to predefined restrictions to remove media entities not satisfying said predefined restrictions.

11. A system for matching a user'"'"'s musical preferences by dynamically generating at least one playlist in accordance with said user'"'"'s musical preferences, comprising:

means for providing a specific choice of user preferences in song content to a content provider;

means for mapping the specific choice of user preferences in a song analysis and matching system using a set of fundamental musical properties that captures the user'"'"'s preferences in song content using human classification techniques and digital signal processing (DSP) techniques;

means for scanning a database using the song analysis and matching system to find other songs that have a similar mapping of musical properties; and

means for generating at least one target playlist having media entities that have a similar mapping of musical properties by using predefined interactions between perceptual analysis and acoustic DSP analysis.

12. The system of claim 11, further comprising means for distributing said generated target playlist to said user.

13. The system of claim 11, wherein said means for generating further comprises:

means for categorizing media entities according to predefined categorization schemes by a music matching and analysis system responsive to instructions from a calling object to generate categorization data sets, said calling object instructions providing one or more characteristics of said media entities for use in categorization; and

means for merging said categorization data sets according to at least one weighted randomization algorithm to generate said target playlists.

14. The system of claim 13, further comprising means for filtering said generated target playlists according to predefined restrictions to remove media entities not satisfying said predefined restrictions.
