There has been active research on 3D broadcasting service with HD resolution (3D HDTV) in ATSC system. The 3D HDTV broadcasting system requires more bandwidth efficient transmission schemes because it should convey both left and right HD resolution images simultaneously in the finite 6MHz bandwidth. Recently more bandwidth efficient modulation and more reliable error correction codes have been considered for the 3D HDTV service. A modified ATSC transmitting system using the BCH and Irregular Repeat Accumulate (IRA) LDPC codes in [3]. The modified ATSC system has SNR gain over the conventional ATSC system but is not sufficient for 3D HDTV service. In this paper, we propose more advanced ATSC transmission schemes that use higher modulation such as 16-QAM and concatenated RS code and block LDPC codes. Compared with conventional ATSC system and the modified ATSC system in [3], the proposed system has about 2.97dB and 1.12dB SNR gain at the payload data rate of 19.44Mbps compared with the existing ATSC system and the modified ATSC system [3]. Also, the proposed scheme requires only 1.05dB power increase for the 3D HDTV service, which is reasonable SNR increase value and applicable to the advanced 3D high definition broadcasting realization in limited 6MHz bandwidth.
