Channel coding, modulation, and transmission for north american digital television
We introduce the transmission system selected for the next generation of North American broadcast television and for high data rate transmission on cable TV systems. We describe key features of the digital vestigial sideband (VSB) modulation and error protection employed in this system, and of the quadrature amplitude modulation (QAM) systems that competed against it for selection. We review the process used to select this system, in addition to the criteria by which the selection was made. We further review the performance of the system under actual field conditions. The 8-VSB terrestrial mode was found to perform better than the existing NTSC broadcasting system. The 16-VSB high data rate cable mode was found to perform essentially error-free at all receiving locations that met Federal Communications Commission (FCC) specifications for carrier-to-noise ratio.
