INTRODUCTIONS
RMC9400 is a professional and high-integrated QAM modulator, with additional re-multiplexing functions for its Tuner and ASI inputs. It is able to accept 1*RF in DVB-S, DVB-S2 or DVB-C mode, multiplexing it with input TS from 2*ASI with SPTS or MPTS. Afterward, the device process the signals by RS encoding, interleaving and QAM modulation. It satisfies a basic QAM modulation function of TS from diversified encoders, multiplexers, scramblers, video servers, DVB gateways and so on, in a stable and mature performance. Due to its multiple configurations and functions, RMC9400 is a professional and independent digital satellite receiver and TS multiplexer at the same time. It has been widely applied to digital TV broadcasting, news gathering, interactive services, broadband satellite systems, and so on.
