  INTRODUCTIONS

REM7004A Four-Channel HDMI & CVBS/YPbPr to RF MPEG-2/H.264 Encoder Modulator offers a professional and high-integration modulator, together with encoding, multiplexing, modulation modules and so on. The device is able to accept 4-channel of HDMI or CVBS or YPbPr, and compress signals in MPEG-2 SD or MPEG-4 AVC/H.264 HD standard. Additional TS from ASI and Tuner(DVB-C, DVB-T/T2, DVB-S/S2) ports is able to be multiplexed with the input channel(s). The device then modulates signals in DVB-C, DVB-T, ATSC-T, or ISDB-T mode in excellent index. Due to its professional and full functions, REM7004A 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.
