Method, apparatus and system for auto-synchronization of compressed content files
First Claim
1. A portable device for synchronizing a compressed content file containing multiple source files, the device comprising:
- a radio frequency transceiver configured to connect to the synchronization server to transmit and receive data related to the compressed content file;
a memory configured to store at least one of the compressed content file, a local compressed content file information, and source file information related to local source files constituting the compressed content file; and
a processor configured to;
detect a synchronization request signal generated by an event modifying the compressed content file,extract at least one modified first source file from the compressed content file based on the source file information,receive a server compressed content file information from the synchronization server,determine whether the compressed content file is modified in the portable device or the synchronization server based on the local compressed content file information and the server compressed content file information, andsynchronize the extracted first source file with a second source file matching among source files stored in a synchronization server.

Abstract
An auto-synchronization method, apparatus, and system for synchronizing compressed content file automatically in such a way of tracing the modification history of source files of the compressed content file and synchronizing the modified source files selectively are provided. The portable device includes a radio communication unit configured to connect to the synchronization server to transmit and receive data related to the compressed content file, a storage unit configured to store at least one of the compressed content file, compressed content file information, and source file information related to source files constituting the compressed content file, and a control unit configured to detect a synchronization request signal generated by an event modifying the compressed content file, extract at least one modified first source file from the compressed content file based on the source file information, and synchronize the extracted first source file with a second source file matching among source files stored in a synchronization server.

7. A synchronization method of a portable device for synchronizing a compressed content file, the method comprising:
-
detecting a synchronization request signal generated by an event modifying the compressed content file; extracting at least one modified first source file based on source file information related to local source files constituting the compressed content file in response to the synchronization request signal; receiving a server compressed content file information, determining whether the compressed content file is modified in the portable device or another device based on a local compressed content file information and the server compressed content file information; and synchronizing the extracted first source file with a second source file matching among source files stored in a synchronization server. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A synchronization system for synchronizing a compressed content file with a synchronization server, the system comprising:
-
a portable device configured to; store at least one of source files information related to local source files constituting a compressed content file, extract modified first source files from the compressed content file based on the source file information, receive a server compressed content file information, determine whether the compressed content file is modified in the portable device or by another device based on the server compressed content file information and a local compressed content file information, and synchronize the extracted first source file among the compressed content file by updating only the modified source files; and a synchronization server configured to; store at least one source file constituting the compressed content file and source file information related to the source file and the server compressed content file information, provide the device with a list of modified second source files information, and synchronize the compressed content file by updating only the modified second source files with the first files stored in the portable device. - View Dependent Claims (15, 16)
