PROMAX Dual DVB-S / DVB-T Transmodulator
The DT-202 modules are DVB-S (QPSK) to DVB-T (COFDM) transmodulators. They
have direct QPSK input that can be tuned to any satellite transponder and
output in the UHF band. They are agile in frequency and output level.
With our exclusive PID filtering function the user can remove video, audio or
data services from the original transport stream. The system allows reducing
bit rate of the incoming satellite transponders to values compatible with COFDM.
Modulation, Forward Error Correction or Guard Interval can be set to the
desired values depending on the application.
This allows packing more programs in a single COFDM channel than a standard
off air DTT channel. A Typical configuration for a coaxial TV distribution
system can be 64QAM, FEC=3/4 and GI=1/32 so that the modulator accepts the
highest bit rate possible.
The dual DVB-S to DVB-T transmodulator (DT-202) includes an internal combiner
that delivers a single DVB-T output with high C/N. This feature gives great
robustness to the signal, allowing adding RF amplifiers in cascade during
distribution with minimal loss of signal quality.
