摘要：
PURPOSE: A method for synchronizing between additional images and reference images of a real-time broadcasting program and a device thereof are provided to perform a signaling operation for synchronization time information with a stream transmitted in real time, thereby providing steadily a stereoscopic picture service. CONSTITUTION: A program map table corresponding to a program selected is extracted(S410). Information defined by a program level descriptor and an elementary stream level descriptor is extracted(S415). Whether a file of a related additional picture stores in a memory is checked(S420). The additional picture is loaded from the memory(S425). Timing difference necessary for synchronization of between a reference picture and the additional picture(S430).
