Abstract

Integrated management of local media files stored at a computer and remote media files accessible via a data communication network. A compressed catalog of the remote media files is stored locally on the computer. A user interface of a media player application displays the contents of a library of local media files and the contents of the compressed catalog. The user interface is configured to receive user input and the media player application is responsive to the user input for performing the media player operations on media files from either the local media library or the compressed catalog or both.

Claims

1. A computerized method of managing media files on a computer coupled to a data communication network, said computer executing a media player application for rendering one or more of the media files, said media files comprising one or more local media files stored at the computer in a first media library and one or more remote media files accessible by the computer via the network, said method comprising:

storing a compressed catalog of the remote media files locally on the computer, said compressed catalog defining a second media library;

displaying contents of the first media library and the second media library in a user interface of the media player application; and

permitting media player operations on one or more of the media files from either the first media library or the second media library or both via the user interface.

2. The method of claim 1, wherein the computer executing the media player application comprises a client and further comprising generating the compressed catalog at a server coupled to the data communication network.

3. The method of claim 2, further comprising executing an update process at the server to update the compressed catalog in response to the media player application accessing the compressed catalog.

4. The method of claim 3, wherein executing the update process includes comparing the compressed catalog to one or more previous catalogs to generate at least one difference file representative of the comparison.

5. The method of claim 4, further comprising merging the difference file and the compressed catalog at the client to generate an updated catalog.

6. The method of claim 1, further comprising querying metadata associated with the media files in the first media library or the second media library or both based on one or more editorial fields to define a playlist.

7. The method of claim 6, wherein the editorial fields comprise one or more of the following:

similar content, similar artists, recommended artists, popularity, featured list, amount of sales, and artist discography.

8. The method of claim 6, further comprising excluding, from the playlist, media files in the second media library having artist metadata matching the artist metadata of one or more of the media files in the first media library.

9. The method of claim 6, further comprising excluding, from the playlist, media files in the second media library having artist metadata not matching the artist metadata of one or more of the media files in the first media library.

10. The method of claim 1, further comprising querying metadata associated with the media files in the first media library based on one or more editorial fields to locally define a playlist of media files from the second media library.

11. The method of claim 1, wherein the compressed catalog contains metadata associated with the remote media files in the second media library.

12. The method of claim 11, wherein the metadata comprises information representing one or more of the following:

track, artist, album, specialty lists, genre, subgenre, and similar artists.

13. The method of claim 1, further comprising displaying a persistent search field in the user interface of the media player application to receive a user-entered search term for querying the compressed catalog, said user interface displaying updated search results as the user enters additional characters of the search term.

14. The method of claim 1, further comprising pre-loading the compressed catalog on the computer.

15. The method of claim 1, wherein one or more computer-readable media have computer-executable instructions for performing the method recited in claim 1.

20. The system of claim 1, wherein the user interface of the media player application includes a persistent search field to receive a user-entered search term for querying the compressed catalog, said user interface displaying updated search results as the user enters additional characters of the search term.

16. A media player system comprising:

a client coupled to a data communication network, said client executing a media player application for rendering one or more media files, said media files comprising one or more local media files stored at the client in a first media library and one or more remote media files accessible by the computer via the network and stored in a second media library;

a compressed catalog of the remote media files, said compressed catalog being stored locally at the client and being representative of the second media library;

a user interface implemented by the media player application for displaying contents of the first media library and the second media library, said user interface being configured to receive user input and said media player application being responsive to the user input for performing one or more media player operations on either the first media library or the second media library or both.

17. The system of claim 16, further comprising a server coupled to the data communication network for generating the compressed catalog.

18. The system of claim 17, further comprising a database of difference files representative of differences between a current version of the second media library and one or more previous versions of the second media library.

19. The system of claim 18, wherein the server executes an update process to update the compressed catalog as a function of the difference files.
