Outline
In the broadcasting process of digital TV programs, QAM modulator mainly complete QAM modulate and up-frequency conversation process for TS stream, Apply to multi-level transmission, broadcasting of digital TV business.
QAM modulator mainly used in head end of digital TV broadcasting, it is composed by two modules QAM modulator and digital up-frequency conversation, modulate the input serial or parallel TS stream via the QAM modulator module, modulate to IF frequency, then pass the up-frequency conversation module to frequency transform, into standard channel or supplement channel which meet demand. Finally mixed enter into CATV network, and received by the terminal STB.
