6 DVB-T/H : Broadcast equipment Transmitter : It consists of a DVB-T/H modulator and a power amplifier, Input signal = ASI Compatible with MFN & SFN network Transmission network is required (microwave link, optical ADM, or satellite) Re-transmitter : It consists of a DVB-T/H receiver and a transmitter, DVB-T/H signal is regenerated on another frequency without additional noise (this solution allow to save money : no transmission network) Local channels can be inserted (ASI input) Compatible with MFN network only Gap filler or transposer : Analog repeater Economical solution to improve coverage (obstacle, building,..) Compatible with MFN & SFN network 6
