Description
Product Overview
HY-21-DVTBXX 8in1/16in1/24in1 DVB-T modulator is an all-in-one device developed by DEXIN. It supports maximum 256 (or 512, or 768) IP input through the GE/SFP port and has 8 (or 16, or 24) multiplexing channels and 8 (or 16, or 24) DVB-T modulating channels of non-adjacent carriers (50MHz~960MHz). The device is characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation DTV broadcasting system.
Key Features
