The IP-MOD 4X UHD is a professional IP-to-coax RF digital modulator that receives up to 64 unicast or multicast IP streams (UDP/RTP) and converts them into 4 independent, fully-multiplexed RF channels you can inject into any coaxial TV distribution system — with true broadcast quality from 50 to 1000 MHz. Select your television standard per output: ATSC (US antenna digital TV), J.83B QAM 64/256 (US digital cable), DVB-T, DVB-C, or DTMB. Each of the four RF frequencies has a full stream remultiplexer: cherry-pick any of the incoming IP programs, assign them to the bouquet you want, and restamp program names, major/minor numbers and LCN so the TV lineup looks exactly how you designed it. Real-time FPGA de-jittering, PCR restamping and automatic packet error correction deliver rock-solid pictures on every TV — from legacy HD-only sets to the newest 4K and 8K televisions. Digitally-synthesized RF output with no harmonics or spurious emissions means you can combine it with existing antenna, cable or VeCOAX modulator channels without interference. Pair it with the VeCASTER 4K-PRO or VeCODER multichannel encoders to build a complete HD/4K channel headend over coax and IP simultaneously. Rack-mount two units in 1RU with the rack plate kit. Designed & made in USA, 5-year warranty, free lifetime tech support.
