ATSC/NTSC & QAM Digital Television Tuners
ATSC is the 8VSB (8-level Vestigial Sideband Modulation) system. This is the digital TV broadcast system chosen by the ATSC (Advanced Television Systems Committee) for broadcast TV in the USA. QAM (Quadrature Amplitude Modulation) is the digital TV system chosen by the U.S. Cable TV companies for use over digital cable. Toshiba integrated digital TVs have both ATSC and QAM digital tuning capability so that you can receive terrestrial digital broadcasts as well as digital “cable-in-the-clear” broadcasts.
