Descriere

The MO-160 / MO-161 is a general purpose DVB-T modulator built in a 1 unit for 19" rack according to the ETSI EN 300 744 v1.5.1 DVB-T specification.

The unit has two ASI inputs for MPEG-2 Transport Stream. The output is a COFDM modulated signal with a selectable frequency or channel from 475 MHz to 875 MHz / 45 MHz to 875 MHz.

The digital codification and modulation process has been implemented over own PROMAX intellectual property programmable logic devices. This is the reason why we can warrant an optimal yield with a very competitive cost.

The MO-160 / MO-161 is ideal for TV distribution applications specially when the advantages of COFDM modulation is required but at same time the distribution cost per program has to be within a budget.

 

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).
