  INTRODUCTIONS

REM7004 4*DVB-S/S2 to DVB-C/DVB-T TransModulator offers a professional and high-integrated modulator, together with demodulation, re-multiplexing and modulation functions. The device is able to accept 4 satellite signals in DVB-S/S2, demodulate and re-multiplex them with additional ASI in or/and RF(DVB-C, DVB-T, ISDB-T or ATSC) in. The device then modulates signals in DVB-T(in 1 or 2 adjacent carriers) or DVB-C(in 1 or 4 adjacent carriers). Due to its professional and full functions, REM7004 has been widely applied to IPTV system, digital TV broadcasting & distribution systems, home entertainment, advertisement broadcasting, etc., in shopping mall, hospital and school, hotel and restaurant, museum, theater, cinema, community, airport, railway station, public square, club, and so on.
