16 in 1 ISDB-T Modulator
Product Overview
ISDBMXX 8in1/16in1 ISDB-T modulator is the latest generational Mux-modulating device developed by GHCOMTEK. It has 8 (or16) multiplexing channels and ISDB-T modulating channels, and supports maximum 512 IP input through the 3 GE ports and 8 (or16) ISDB-T non-adjacent carriers (50MHz~960MHz) output through the RF output interface. The device is also characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation DTV broadcasting system.
