Abstract: PURPOSE: A method for synchronizing a reference image with an additional image of a real time broadcast program and a transceiving system therefor are provided to notify the start time of a reference image to a receiver while minimizing changes of a digital broadcast transmitting system. CONSTITUTION: A transmitting server(610) generates a frame which includes an identifier for notifying the start time of a reference image to a receiver in advance. A reference image encoder(652) encodes a reference image in real time. An additional image encoder(654) encodes an additional image. The identifier is a recognition marker or a predetermined pattern which notifies the start time of the reference image.

Abstract: PURPOSE: A method for non real time stereoscopic video service and a device thereof are provided to synchronize a reference video and an additional video when time information of a target playing video frame is not acquired. CONSTITUTION: A broadcasting receiving device extracts a PAT(Program Association Table) in a received MPEG-2 TS(Transport Stream)(S210). The device extracts a PMT corresponding to a selected program from the MPEG-2 TS(S220). The device extracts a stereoscopic service descriptor from the extracted PMT. The device analyzes information analyzed by the stereoscopic service descriptor(S230). The device generates a playing video frame and time information(S240). The device acquires additional information corresponding to a reference information form a storage device(S250).
