Main features
Digital Transmodulation (COFDM to QAM) with Transport Stream Processing
Optional Blockade of Services, PIDs and Conditionnal Accesses, with Regeneration of Tables.
The COFDM channels located in the 174-230 MHz or 470-862 MHz bands are transformed to QAM channels located in the 47-862 MHz band
A TDI transmodulator carries out the complete channel processing from the input to the output:

tunes a COFDM digital channel,
demodulates the signal being received,
processes the transport stream, and
re-modulates it in QAM format (16, 32, 64, 128 or 256 symbols) on an RF channel that is selectable within the 45-862 MHz frequency range.
