Abstract: Method and device for synchronizing reference image and supplementary image in real-time broadcast program. The present invention provides a synchronization method for: calculating a time difference between a current frame of a reference image and a reference time stamp on the basis of the reference time stamp, which is contained in a program level descriptor and indicates a start time of a frame regarding a reference image; and adjusting synchronization between the frame regarding the reference image and a frame regarding a supplementary image by using the time difference. Since synchronous time information is signaled together with a stream delivered in real time, synchronization between a stored supplementary image and a reference image transmitted in real time is enabled even though a first PMT of a time when a stereoscopic video service is started is not received or a packet error is generated. Thus, the invention can provide a stable stereoscopic image service

Abstract: The present invention relates to a method of synchronizing a reference image with an additional image of a real-time broadcasting program, the method comprising the steps of: generating at least one frame having a predetermined identifier for providing notice of the start time of the reference image to a receiver in advance; and transmitting at least one frame having the predetermined identifier to the receiver. Alternatively, the method of synchronizing a reference image with an additional image of a real-time broadcasting program comprises the steps of: generating signaling information containing additional image interlocking information at a transmission side in order to prepare for the additional image interlocked with the reference image of the real-time broadcasting program at a reception side in advance; and providing the signaling information to the receiver. Therefore, it is possible to accurately and effectively perform the synchronization of a 3D reference image of the real-time broadcasting program with a 3D additional image stored in the receiver or a streamed 3D additional image.
