The Promax MO-480 is a broadcast grade DVB-T2 modulator available in a standard 1U high 19" rack case (MO480) and also in an open frame chassis (MO-481) that can be used for MFN as well as SFN applications.

The modulator has several Transport Stream and T2-MI inputs in ASI and IP formats so that it can be easily interfaced with other existing transmission equipments such as gateways. The modulator can be configured to generate any of the transmission modes listed in the corresponding DVB-T2 standard including single and multiple PLP, MISO or SISO. It can also be used for DVB-T applications.

The interest in DVB-T2 is now increasing with the growing demand for bandwidth mostly to deliver high definition television programs. Several countries already have T2 commercial services, some others are running test trials and many more are on the planning stage..

Input Stream Interface 2 x ASI (EN 102 773)
1 x IP (SMPTE-2022 – UDP, RTP and FEC)
System A Input Mode TS input (one PLP, HEM mode, no NULL packet deletion, no ISSY, no in-band signalling)
System A & B Input Mode T2-MI over TS input with automatic search for the T2-MI data piping PID
T2-MI Encapsulation MPEG-2 TS (ASI) and MPEG-2 TS over IP (IP)
Switching Automatic and seamless between any two T2-MI inputs in SFN mode. Automatic in MFN mode In both modes, the switchover may be permanent or temporary
