Abstract
The dual-stream based stereoscopic 3D HDTV broadcasting service was launched recently. Although the dual-stream basedHDTV service has been successfully provided, the 3D HDTV broadcasting system requires more bandwidth efficienttransmission schemes because it should convey both left and right HD resolution images simultaneously in the finite 6MHzbandwidth. In this paper, we consider more advanced ATSC transmission schemes that use higher modulation such as16-QAM and concatenated RS code and block LDPC codes. Compared with conventional ATSC system and the modifiedATSC system in [2], the proposed system has about 2.97dB and 1.12dB SNR gain at the payload data rate of 19.44Mbpscompared with the existing ATSC system and the modified ATSC system [2]. Also, the proposed scheme requires only1.05dB power increase for the 3D HDTV service, which is reasonable SNR increase value and applicable to the advanced3D high definition broadcasting realization in limited 6MHz bandwidth.
