  • TRANSMISSON APPARATUS AND METHOD AND RECEPTION APPARATUS AND METHOD FOR PROVIDING PROGRAM ASSOCIATED STEREOSCOPIC BROADCASTING SERVICE
    Publication number: 20130342648
    Abstract: Disclosed herein are a transmission apparatus and method and a reception apparatus and method for a program associated stereoscopic broadcasting service. The transmission apparatus includes: a real time stream encoder generating a real time stream by encoding a reference image; a non-real time (NRT) stream encoder generating an NRT stream based on an additional image; an image synchronization information generator generating a service signaling and image synchronization information (including an event information table (EIT) and a program map table (PMT)) stream for synchronizing the reference image and the additional image with each other based on 3D content synchronization information; and a re-multiplexer generating a program associated stereoscopic broadcasting stream by multiplexing the real time stream, the non-real time stream, and the service signaling and image synchronizing information stream.
