What is a digital QAM Tuner?

QAM stands for Quadrature Amplitude Modulation. It is similar to AM (Amplitude Modulation) or FM (Frequency Modulation). With the QAM tuner, users can connect their cable directly to their TV and watch any digital and/or HD cable station that is not encrypted, without the use of a set-top box. Most HD or digital TVs sold after 2006 have an internal digital QAM tuner. Check your owner's manual to ensure that your TV has an internal QAM tuner.
