The DT-101 (single) and DT-102 (dual) modules are COFDM modulators compatible with DVB-T standard. They have TS-ASI input and RF output in the UHF band and are agile in frequency and output level. Inputs can contain services in all sorts of formats: SD, HD, MPEG-2, MPEG-4, etc.
With our exclusive PID filtering function the user can remove video, audio or data services from the original transport stream. In case of using the DT-301 / DT-302 as a receiver, the system allows to reduce bit rate of the incoming satellite transponders to values that can be used in 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 possible bit rate.
