HV-202J

Professional 4-band Full HD Digital TV Modulator

SDI/HD-SDI/HDMI to ISDB-T/ISDB-Tb

100–2500 MHz

HV-202 is the most cost-effective solution to distribute HDMI or HD-SDI video to unlimited standard TV’s without requiring any special adapter. The video input source from either HDMI/DVI or HD-SDI is encoded in MPEG2 or H.264 streams, modulated with the open industrial 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 compliant receivers, including SetTopBox, Digital TV, PC/NB USB DTV dongle, or DTV capture card can receive, and watch the video from a HV-202 via the standard coaxial cable or antenna.

Features

  • 01 High Performance Wide Frequency Range Support — Direct digital conversion to 100..2500 MHz for excellent signal quality. Professional grade modulation error rate (MER).
  • 02 Flexible Bandwidth Option — In DVB-T mode, 1MHz~8MHz Bandwidth options are supported.
  • 03 UART Digital Data Mux — HV-202 supports UART data mux feature. GPS or aviation data can be multiplexed in the transmitted stream from HV-202’s UART port. Besides audio and video, the receiver can decode the received UART data for further data processing. The communication parameters for the data mux UART port are configurable.
  • 04 Video Streaming and Web Management — HV-202 supports network video streaming input/output and Web interface for remote management.
  • 05 Low Cost HD Video Distribution — Compliant to existing HD TV sets, no extra adapter required, and no restriction on the number of receivers. All the peripherals like splitter, amplifier, connector…etc are the same as those for regular TV.
  • 06 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 compliant to existing SD TV sets or STB’s.
  • 07 Easy to Configure — Channel number can be configured with the built-in keypad switch easily. More advanced configurations can be set from an external host like PC/NB or Tablet/Pad thru USB interface. Remote Web management is also supported.
  • 08 Robust, Reliable and Long Distance — Easily transmit 1080p video over a single 3C2V/RG59 cable for at least 500 meters long without adding any repeater. For wireless applications, the line of sight transmission distance may reach 50~100 meters at 0dBm RF radiation power and up to several kilo meters at 30 dBm with an optional PA. The real distance depends on the antenna design and receiver quality. Differential RF output is also available for RF signal distribution with twisted pairs (telephone or Ethernet RJ-45) instead of heavy coaxial cables.
  • 09 Daisy-chain Connection (Bus-Topology) — Multiple HV-202’s with different channel configurations can share a single cable. It can dramatically reduce the cable deployment cost and effort.
  • 10 Real time protocol and Low latency — No frame drop in QEF (Quasi-Error-Free) condition, and low transmission latency.
