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 heterogeneous network-based linked broadcast content transmitting/receiving system and method. A transmission system generates a basic content stream on basic content constituting broadcast content and transmits the generated basic content stream to a terminal through a broadcast network, and also generates an additional content stream on additional content linked to the basic content and transmits the generated additional content stream to a terminal through a communication network. At least one of linkage playback information on the basic content and linkage playback information on the additional content is further transmitted to the terminal. Additionally, a reception terminal receives the basic content stream, the additional content stream, and the linkage playback information, and then synchronizes the basic content with the additional content and plays them back in order to playback broadcast content in real time.

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.
