BBG / ARX / Febr uar y 2006
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
