    摘要: Provided are a method and apparatus of synchronizing a reference picture and an additional picture of a real-time broadcasting program. The method includes: receiving an MPEG-2 transport stream (MPEG-2 TS) including a program level descriptor and an elementary stream (ES) level descriptor from a picture transmitting apparatus; loading an additional picture, corresponding to a reference picture included in the elementary stream (ES) level descriptor from a memory provided in the picture receiving apparatus, based on file information regarding the reference picture; calculating a time difference between a current frame of the reference picture and a reference time stamp, based on the reference time stamp which is included in the program level descriptor and indicates a start time of a frame regarding the reference picture; synchronizing the frame regarding the reference picture and a frame regarding the additional picture by using the time difference; and providing a stereoscopic picture based on the synchronized frames regarding the reference picture and the additional picture. A stereoscopic video service can be stably provided.

    摘要: Disclosed are an apparatus and a method for transmitting a broadcasting service capable of signaling non-real-time 3D broadcasting content. An apparatus for transmitting a broadcasting service includes: a non-real-time (NRT) content encoder encoding stereoscopic image content including a reference image and an additional image to generate an NRT stream; an NRT signaling information encoder generating NRT signaling information including at least one of a service map table (SMT) and a non-real-time-information table (NRT-IT) that correspond to the content; and a multiplexer multiplexing the NRT stream and the NRT signaling information and transmitting the multiplexed NRT stream and NRT signaling information to a receiving apparatus. Therefore, content can be provided even when the reference image and the additional image are encoded into the single file format in the dual stream type.
