DVB-T DVB-H Transmitters and Transposers

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

7
