Abstract: PURPOSE: A synchronization method for implementing a 3D service in ATSC-M/H is provided to adjust synchronism between a TS(transmission stream)-M stream and an M/H stream. CONSTITUTION: A TS inputted to a dual stream through a receiver is separated into a TS-M stream and a M/H stream through an inverse multiplexer. Each of timing models is analyzed to adjust synchronism between streams including two different timing models and to find reference information shared between the timing models. Synchronization between heterogeneous streams is performed based on PTS(Presentation Time Stamp) information generated through a wall-clock. A 3D image is formed through the synchronization by using the heterogeneous streams having the same time synchronism.
