MOBILE TELECOMMUNICATION SYSTEM, AND METHOD FOR SYNCHRONIZATION BETWEEN BROADCASTING CONTENTS AND DATA INFORMATION

摘要

PURPOSE: A mobile communication broadcasting system and a method for synchronizing broadcasting contents with additional information are provided to overcome the uni-directionality of a satellite DMB broadcast service and a terrestrial DMB broadcast service and show PPL information requested by a user just in time by synchronizing it with corresponding broadcasting contents. CONSTITUTION: A mobile communication broadcasting system(100) comprises a digital broadcast receiving terminal, a service providing server(120), and a synchronizing server(130). The digital broadcast receiving terminal receives broadcasting contents about digital multimedia and displays PPL(Product Placement) information based on synchronization information. The service providing server stores a scene change file about the broadcasting contents and transmits the synchronization information to the digital broadcast receiving terminal when receiving it after transmitting a synchronization information request message. The synchronizing server downloads the scene change file based on the synchronization information request message from service providing server.
