HV-202 Professional 4-band(100MHz~2500MHz) Full HD DigitalTV Modulator
HD-SDI/HDMI to DVB-T/ISDB-T/ISDB-Tb
HV-202 is the most cost-effective solutionto distribute HDMI or composite (CVBS) video to unlimited standard TV’s withoutrequiring any special adapter.
The video input source from either HDMI/DVIor HD-SDI is encoded in MPEG2 or H.264 streams, modulated with the openindustrial standard EN 300-744 DVB-T/ARIB STD-B31 ISDB-T/ABNT NBR 15601 ISDB-Tb,and then transmitted over cable or air.
All DVB-T/ISDB-T/ ISDB-Tb compliantreceivers, including SetTopBox, Digital TV, PC/NB USB DTV dongle, or DTV capturecard can receive, and watch the video from a HV-202 via the standard coaxialcable or antenna.
Features
High Performance Wide Frequency Rage Support
Direct digital conversion to 100..2500 MHz for excellent signalquality
Professionalgrade modulation error rate (MER)
Low Cost HD Video Distribution
Compliant to existing HD TV sets, no extra adapter required, and norestriction on the number of receivers. All the peripherals like splitter,amplifier, connector…etc are the same as those for regular TV.
Versatile video inputs and formats
Support HDMI/DVI and HD-SDI video input.
Besides H.264/MPEG2 HD, MPEG2 SD format is also supported and complaintto existing SD TV sets or STB’s.
Easy to Configure
Channel number can be configured with the built-in keypad switcheasily.
More advanced configurations can be set from an external host likePC/NB or Tablet/Pad thru USB interface.
Robust, Reliable and Long Distance
Easily transmit 1080p video over a single 3C2V/RG59 cable for at least 500 meters long withoutadding any repeater.
For wireless applications, the line of sight transmission distancemay reach 50~100 meters at 0dBm RF radiation power and up to several kilometers at 20 dBm. The real distance depends on the antenna design and receiverquality.
Differential RF output is also available for RF signal distributionwith twisted pairs (telephone or Ethernet RJ-45) instead of heavy coaxialcables.
Daisy-chain Connection (Bus-Topology)
Multiple HV-202’swith different channel configurations can share a single cable. It candramatically reduce the cable deployment cost and effort.
Real time protocol and Low latency
No frame drop in QEF (Quasi-Error-Free) condition, and lowtransmission latency
