1. A method of transferring media data to a network coupled apparatus, comprising:
- (a) maintaining a personal information space identified with a user including media data comprising a directory of digital media files, the personal information space being coupled to a server and a network;
(b) generating a first version of the media data in the personal information space;
(c) generating a digital media file, in response to an input from the user, comprising a second version of the media data in a same format as the first version in the personal information space, the second version including an update not included in the first version;
(d) obtaining difference information comprising differences between the first version of the media data and the second version of the media data; and
(e) transferring a digital media file over the network containing the difference information from the personal information space to the network coupled apparatus in response to a sync request made from a web browser at the network-coupled apparatus by the user.

11. A system for transferring digital media between a plurality of network coupled devices, comprising:
-
a personal information store identified with a user containing digital media comprising a directory of digital media files readable by an application program; and
a processing device, a server and a network coupled with the personal information store, the processing device including;an application data store holding a version of the digital media in the personal information store, and a device engine to;
a) generate a digital media file, in response to an input from the user, comprising a second version of the media data in a same format as the first version in the personal information store, the second version including an update not included in the first version;
(b) obtain difference information comprising differences between the first version of the media data and the second version of the media data; and
(c) transfer a digital media file over the network containing the difference information from the personal information space to the network coupled apparatus in response to a sync request made from a web browser at the network-coupled apparatus by the user. - View Dependent Claims (12, 13, 14)
