maximal 4-channel TS input; Output 4 neighbour frequencies; RF and IF output after receiving the SPTS or MPTS;
TheV-SHINE®NVQM-4 4-channel QAM Modulator is a high-performance QAM modulator with frequency agility, using the complete digital modulation and the high/middle frequency technology and supporting ASI and DS3 signal input. It could also implement the independent input of multi-TS, execute the static PSI/SI and finish the PID remapping and filtering. There are RF and IF output after receiving the SPTS or MPTS, RS encoding and modulation, finally to the DVB application system such as HFC or MMDS.
