EM-01 is professional device integrated with Encoding and Modulation functions. It is equiped with A/V or HDMI ?input. After digital compression, channel coding ?and modulation will be done according to QAM/DVB-T/ISDB-T/ATSC standard. The modulated signal will be upcoverted to the working frequency of digital cable TV, and output in RF. This equipment is with excellen RF proformance, and can be used as modulator in the headend of? digital cable or MMDS wireless TV network. ? ? Features? ?
