Full HD Digital TV Modulator

Name: HV-102J Full HD Digital TV Modulator
Brand: HiDes Technology
SKU: HV-102J

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

50–950 MHz, 1200–1350 MHz

HV-102J is a Full HD digital TV modulator that encodes an HD-SDI or HDMI video source in H.264 or MPEG2 and modulates it to ISDB-T (ARIB STD-B31) or ISDB-Tb (ABNT NBR 15601) for distribution over coaxial cable or air. Any compliant TV set or set-top box can receive it with no extra adapter required.

Features

01 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.
02 Versatile video inputs and formats — Support VGA and component (YPbPr) video input. Besides H.264/MPEG2 HD, MPEG2 SD format is also supported and compliant to existing SD TV sets or STB's.
03 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.
04 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 20 dBm. 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.
05 Daisy-chain Connection (Bus-Topology) — Multiple HV-102's with different channel configurations can share a single cable. It can dramatically reduce the cable deployment cost and effort.
06 Real time protocol and Low latency — No frame drop in QEF (Quasi-Error-Free) condition, and low transmission latency.

Note 1: output formats supported depend on the video input formats. The frame rate should be consistent and the encoded video frame size should be less or equal to the original input.
Note 2: For VGA-input, the encoded frame size can only be the same as the input.
There could be MER loss in high gain/attenuation level.
Specifications are subject to change without prior notice.
