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).

Abstract: PURPOSE: A method and an apparatus for synchronizing a 3D image are provided to automatically synchronize a 3D image if a frame of a left image is not synchronized with a frame of a right image. CONSTITUTION: A 3D image synchronization device determines a reference area of a first image and a corresponding area of a second image(S100). Specific values of the reference area and the corresponding area are calculated(S200). A frame difference value is extracted between the first image and the second image(S300). One of the first image and the second image is moved in a time domain(S400).
