4-Channel Transmodulator

WDH-1540TM is a high density 4-Way modulator and trans-modulator module. It could receive up to 4 independent TS streams from Tuner, ASI or TS/IP (note 1) inputs, then modulates and combines them to 4 adjacent DVB-C RF carriers over a coaxial output. Different types of inputs are available as factory options, such as DVB-S/S2, DVB-C/T/T2 and ASI. With its built-in remux (note 1) functional block, WDH-1540TM also provides TV program filtering and re-multiplexing of TS inputs(note 2) to rebuild new TS outputs for modulation. TS/IP input is a software option.
