description A method and apparatus for synchronizing EPG information between a server and a client in a digital broadcasting network are provided. The server updates synchronization files according to information which is modified after a last synchronization file is created according to the update of the server-side EPG information, creates a synchronization file according to information which is modified after the last synchronization file is created, and transfers a synchronization file to one of the clients, where the synchronization file is created first after the EPG information pieces of the clients are updated among from the synchronization files stored in the clients. Accordingly, the server and the client can be easily synchronized with each other by transferring or receiving only one file, since all synchronization files can include the latest update history by transferring only one synchronization file.
