What is the difference between ATSC and NTSC?
NTSC is generally used to refer to the old analog signal which was first adopted in the USA in the 1940s. It has largely been phased out in favor of digital ATSC broadcasting. NTSC is inferior to ATSC, as it is doesn't deliver HDTV picture quality, or the widescreen format.
What is an ATSC antenna?
An ATSC (Advanced Television Systems Committee) tuner, often called an ATSC receiver or HDTV tuner, is a type of television tuner that allows reception of digital television (DTV) television channels that use ATSC standards, as transmitted by television stations in North America, parts of Central America, and South ...
Does my TV have an ATSC tuner?

What is QAM used for?
QAM (quadrature amplitude modulation) is a method of combining two amplitude-modulated (AM) signals into a single channel, thereby doubling the effective bandwidth. QAM is used with pulse amplitude modulation (PAM) in digital systems, especially in wireless applications.
What does QAM stand for?
Key Takeaway: QAM (quadrature amplitude modulation) is a modulation scheme used by network operators when transmitting data. QAM relates to a way of changing the amplitude, or power level, of two signals. QAM enables an analog signal to efficiently transmit digital information and increases the useable bandwidth.
What format is ATSC?
Advanced Television Systems Committee (ATSC) standards are an American set of standards for digital television transmission over terrestrial, cable and satellite networks. ... ATSC includes two primary high definition video formats, 1080i and 720p.
What does QAM compatible mean?
