INTRODUCTIONS
RMC9000 is designed and configured according to standard of European broadband satellite telecommunication, DVB-C(EN300 429). 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. Apart from its ASI input and RF output paths, it also deals with the TS by RS encoding and convolution interlacing. RMC9000 is a simple but basic and significant device, also integrated with functions of PCR accurate adjusting, PID filtering, remapping, PSI/SI synchronously updating, NIT insertion, etc.. It has been widely applied to digital TV broadcasting, news gathering, interactive services, broadband satellite systems, and so on.
