Descriere

The MO-180 is a DVB-T/H modulator for SFN/MFN implemented in a standard 1U 19" rack.

The modulator has two Transport Stream DVB-ASI and one DVB-SPI TS inputs. It has 10 MHz 1 pps input to be used together the MIP packet contained in the Transport Stream, to allow the SFN synchronisation.

 

Services included in the transport stream can be audio, video or data in MPEG-2, MPEG-4 formats and can correspond to free to air or encrypted programs in standard definition (SDTV) or high definition (HDTV).
