Descriere

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.
