Application
The V-SHINE®NVQM2 2-channel QAM Modulator is a key component for the cost-effective deployment and running of broadcast services over cable networks. The NVQM2 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 other DTV networks.
