Method and apparatus for synchronizing multimedia content with device which supports multi-server environment
First Claim
1. A server comprising:
- a synchronization policy management unit which acquires a synchronization policy for synchronization of multimedia content or meta data of the multimedia content with a client connected to the server;
a synchronization information collector which collects log information of a previously performed synchronization with the client and a change occurring after the previously performed synchronization, from the client;
a synchronization processor which performs synchronization with the client in accordance with the log information;
a change log management unit which stores a result of the synchronization with the client in the log information;
an interface unit which transmits the log information so as to store the result of the synchronization in the log information of the client; and
a storage unit which stores the multimedia content and the meta data of the multimedia content.

Abstract
A method and apparatus for synchronizing multimedia content with a client device which supports a multi-server environment are provided. The server includes a synchronization policy management unit which acquires a synchronization policy; a synchronization information collector which collects log information of a previously performed synchronization and of a change occurring after the previously performed synchronization; a synchronization processor which performs synchronization in accordance with the collected log information; a change log management unit which stores a result of the synchronization; an interface unit which transmits the log information; and a storage unit which stores the multimedia content and the meta data of the multimedia content. The method includes acquiring a synchronization policy; collecting log information of a previous synchronization; performing synchronization with the client based on the collected log information; storing a result of the synchronization in the log information.
