    Abstract: A digital broadcast protocol conversion system including: a PSIP/PSI extractor for demultiplexing a transport stream of an ATSC broadcast standard to extract PSIP/PSI data; an SI/PSI extractor for demultiplexing a transport stream of a DVB broadcast standard to extract SI/PSI data; a protocol converter for converting the PSIP/PSI data to SI′/PSI′ data corresponding to a broadcast protocol of the DVB broadcast standard or converting the SI/PSI data to PSIP′/PSI′ data corresponding to a broadcast protocol of the ATSC broadcast standard; and a multiplexer for multiplexing the SI′/PSI′ data and the transport stream having the PSIP/PSI data extracted therefrom, or multiplexing the PSIP′/PSI′ data and the transport stream having the PSIP/PSI data extracted therefrom, thereby converting the broadcast protocol between different broadcast standards.

    Abstract: A data processing system and method for stereoscopic 3D video based on MPEG-4. Various elementary streams of left and right images of stereoscopic 3D video are multiplexed into a single stream, and efficient buffer management is performed through field encoding that supports possible display methods. The system minimizes the synchronization time of left and right images and reduces the complexity of the decoder model. Also, a decoding buffer size is allocated to enable support of stereoscopic 3D video field/frame shuttering and stereoscopic 3D video polarized display, while maintaining compatibility with conventional 2D video data processing. Finally, only DTS and CTS are transmitted at the same time, and DTS and CTS of the remaining times are estimated to thereby simplify synchronization.
