Abstract

A system and method for archiving a user'"'"'s media collection are provided. In general, a central archiving system stores high-quality versions of a number of known media files and a number of known encoding algorithms. First, each media file in the user'"'"'s media collection and an encoding algorithm used to encode each media file are classified as either known or unknown to the archiving server. For each known media file encoded with a known encoding algorithm, the archive includes information identifying the media file, information identifying the encoding algorithm for the media file, and optionally the one or more quality parameters such as bit rate, sampling frequency, and the like for the media file. For each unknown media file and/or media file encoded with an unknown CODEC or encoding algorithm, the archive includes the media file, which is uploaded and stored at the archiving system.

validating an identification of the at least one of the plurality of media files by comparison of the at least one fingerprint to at least one fingerprint for the media content of the at least one of the plurality of reference media files.

9. The method of claim 1 further comprising receiving at least one quality parameter for each of the plurality of media files, wherein generating the archive record further comprises storing the at least one quality parameter for each of the plurality of media files.

10. The method of claim 1 further comprising restoring the user'"'"'s media collection to the user system.

11. The method of claim 10 wherein restoring the user'"'"'s media collection comprises:

receiving a request from the user system to restore the user'"'"'s media collection;

recreating, at the central archiving system, each one of the plurality of media files using one of the plurality of reference media files stored at the central archiving system and one of a plurality of encoding algorithms corresponding to the media content and the encoding algorithm identified for the one of the plurality of media files in the archive record; and

providing the plurality of media files to the user system.

12. The method of claim 10 further comprising:

authorizing a plurality of authorized user systems including the user system, the plurality of authorized user systems limited to a predetermined number of user systems;

wherein restoring the user'"'"'s media collection is limited to restoring the user'"'"'s media collection to the plurality of authorized user systems.

13. The method of claim 12 further comprising:

changing one of the plurality of authorized user systems to another user system; and

limiting the step of changing the one of the plurality of authorized user systems to another user system such that the step of changing cannot occur within a predetermined amount of time after authorizing one of the plurality of authorized user systems.

14. The method of claim 12 further comprising:

changing one of the plurality of authorized user systems to another user system; and

limiting the step of changing the one of the plurality of authorized user systems to the other user system such that the step of changing cannot occur unless the other user system is within a predetermined distance from the one of the plurality of authorized user systems.

15. The method of claim 1 wherein the user'"'"'s media collection comprises at least one unique media file having media content that is unknown to the central archiving system or encoded using an encoding algorithm that is unknown to the central archiving system, and the method further comprises:

identifying the at least one unique media file as a unique media file having either media content that is unknown to the central archiving system or media content encoded with an encoding algorithm that is unknown to the central archiving system based on the information regarding the media content and the information regarding the encoding algorithm for the at least one unique media file;

obtaining the at least one unique media file from the user system; and

storing the at least one unique media file in association with the archive record operating as an archive of the user'"'"'s media collection.

16. The method of claim 15 wherein media content is unknown to the archiving system if a reference media file corresponding to the media content is not stored by the central archiving system, and an encoding algorithm is unknown to the central archiving system if the encoding algorithm is not stored by the central archiving system.
