Definition

QAM (Quadrature Amplitude Modulation) is a digital scheme used to transmit over Radio Frequency (RF). For example, QAM is used for Digital TV (DTV) transmission (both live and VOD) over last mile (e.g. Fiber/Coaxial) from a CMTS (which has a QAM subsystem sending out data onto the RF plant) and a Cable Modem (which has a QAM subsystem to receive and demodulate the data) at customer premises.

It is typically referred as a way to distribute video in a “traditional” way in opposition with the news ways to distribute video directly over .
