DMB-24E Transmodulator 24 Channels FTA Tuners to RF Transmodulator DVB-SS2 to DVB-T Remodulator
Overview
DMB-24E Series 8/12/16/20/24 channels RF TO RF broadcast transmodulator, 4 tuners ports per module up to 6 modules in back panel, demodulate the modulated RF signal and multiplexing, then up-converter modulating adjacent carrier out. The tuners input support two tuner different types chose from DVB-S/S2/T/T2/C/ISDB-T/ATSC-T. Not only tuners input, this item supports tuners and HDMI mixed input.
DIGICAST DMB-24E Transmodulator is a high density demodulating and modulation all in one digital broadcast headend equipment that has 24 FTA tuner inputs to convert to 4 or 8 non-adjacent carrier outputs with multiplexing. It also supports 128*MPTS/ SPTS UDP/ IP inputs and 1*MPTS & 127*SPTS UDP/RTP IP output through DATA port and TS input for re-mux through 2 ASI ports.
This is the new generation equipment which conversion RF programs to other RF standard and IP TS that are easily managed via web management to help transmission all of your programs to your local RF system.
