Application

The V-SHINE^®NVQM4 4-channel QAM Modulator is a key component for the cost-effective deployment and running of brodcast service over cable networks.The NVQM4 can achieve four-way independent input TS streams and modulation,also provides static PSI/SI parsing and modification,PID filtering and remapping. It can be widely used in HFC,MMDS and the oher DTV networks.
