Abstract

A system compiles a music playlist to accommodate the tastes of various participants in a group setting. A music profile is created for each participant, the profile containing representations of songs that are characteristic of the participant'"'"'s tastes. A master device may then compile a “super profile” that constitutes a compilation of the various participant profiles. Each participant device may then access the super profile and search among its specific song collection to find music that is similar to one or more songs represented in the super profile. From such songs, the master device may compile a playlist of songs that are similar among the participant devices, thereby representing the songs that correspond to the collective musical tastes of the participants. The playlist may be updated as participants enter and leave the group to track the changing collective tastes of the participants.

Claims

1. A method of generating shared media content comprising:

generating a plurality of media content profiles for a corresponding plurality of participant devices, wherein a media content profile includes a representation of at least one corresponding media file in the corresponding participant device;

combining the plurality of media content profiles into a super profile;

comparing media files in the plurality of participant devices to the super profile based on comparison criteria; and

identifying at least one media file in a participant device that satisfies the comparison criteria.

2. The method of claim 1, wherein the generating step for each of the plurality of media content profiles comprises:

creating a plurality of seeds, each seed being a representation of a corresponding media file accessible by a corresponding participant device; and

combining the plurality of seeds into the media content profile for the corresponding participant device.

3. The method of claim 2, wherein the media files are music files, and each seed includes musical characteristics data and an acoustic identifier for the corresponding music file.

4. The method of claim 2, wherein the super profile includes seeds contained in the combined plurality of media content profiles.

5. The method of claim 4, wherein the comparing step includes comparing the media files of the plurality of participant devices to the seeds in the super profile, the comparison criteria being a designated similarity between a compared media file and at least one seed in the super profile.

6. The method of claim 1, further comprising:

for each participant device, compiling a list of the identified media files that satisfy the comparison criteria; and

combining the lists for each of the plurality of participant devices into a master playlist.

7. The method of claim 1, further comprising playing the at least one identified media file, wherein the playing step comprises transmitting a playback command to a participant device having access to the media file to be played, and wherein the media file is played by the participant device.

8. A host device for a media content sharing system comprising:

an input interface; and

a controller configured to receive a plurality of media content profiles for a plurality of corresponding participant devices wherein a media content profile includes a representation of at least one corresponding media file in the corresponding participant device, and to combine the plurality of media content profiles into a super profile, wherein media files in the plurality of participant devices are compared to the super profile based on comparison criteria; and

the controller is further configured to receive via the input interface an identification of at least one media file in a participant device that satisfies the comparison criteria.

9. The host device of claim 8, wherein the controller is configured to receive the media content profiles by receiving seed data corresponding to media files in the participant devices, and generating a music profile for each of the participant devices.

10. The host device of claim 8, wherein each music profile includes a plurality of seeds, each seed being a representation of a corresponding media file accessible by a corresponding participant device.

11. The host device of claim 10, wherein the super profile includes seeds contained in the plurality of media content profiles.

12. The host device of claim 8, further comprising an output interface, wherein the host device transmits the super profile to each participant device via the output interface.

13. The host device of claim 8, further comprising an output interface, wherein for an identified media file, the host device transmits a playback command over the output interface to cause a participant device having access to the identified media file to play the media file.

14. The host device of claim 8, wherein the controller is further configured to receive via the input interface, and from each participant device, a list of identifications of a plurality of media files that satisfy the comparison criteria, and to combine the lists into a master playlist.

15. A participant device for a media content sharing system comprising:

a storage device containing a plurality of stored media files;

an input interface for receiving a super profile containing media content profiles corresponding to a plurality of other participant devices, wherein a media content profile includes a representation of at least one corresponding media file in the corresponding participant device;

a controller configured to compare the stored media files to the super profile based on comparison criteria to identify at least stored one media file that satisfies the comparison criteria; and

an output interface, wherein the controller is further configured to transmit the identification of at least one identified media file to a host device.

16. The participant device of claim 15, wherein the super profile includes a plurality of seeds, each seed being a representation of a corresponding media file accessible by a corresponding participant device.

17. The participant device of claim 16, wherein the media files are music files, and each seed includes musical characteristics data and an acoustic identifier.

18. The participant device of claim 16, wherein the controller is configured to compare the stored media files to the seeds in the super profile, the comparison criteria being a designated similarity between a compared media file and at least one seed in the super profile, and the controller is further configured to generate a list of identifications of a plurality of media files that satisfy the comparison criteria and to transmit the list to the host device.

19. The participant device of claim 15, wherein the participant device receives a playback command via the input interface corresponding to an identified media file, and the controller is further configured to stream the media file via the output interface to an output system for playback.

20. The participant device of claim 15, wherein the participant device is a mobile telephone.
