IP To DVB-C Modulator
SFT3332 (V2) 16 in 1 (or 32 in 1) IP to DVB-C modulator is an all-in-one device developed by SOFTEL. It supports maximum 1024 IP input through the 4 GE/SFP port and also 6 ASI input. After multiplexing, scrambling 16(or 32) and DVB-C modulating, it gives 16(or 32) non-adjacent carriers (50MHz~960MHz), 2 ASI output and 16 or 32 IP (MPTS) output as mirror of carriers. The device is characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation DTV broadcasting system.
