IPQAM modulator could convert the gigabytes IP input to the TS and output the RF signals (Maximal 24 frequencies).
V-SHINE®NVQM-I is a IPQAM modulator with high performance. The technology of the complete digital modulation and direct RF could convert the gigabytes IP input to the TS and output the RF signals after modulation. This device could be set on any cross of the head-end, sub-head-end and sub-area main fiber line to receive the data of the MPEG over IP and GbE and then make them multiplexed, scrambled, modulated and up-mixed to RF signals, which would bes ent to the digital TV network. It is widely used in the field of digital TV systems and interactive TV service of HFC network or microwave MMDS.
