HV-320J

FPV Full HD Video Transmitter

Name: HV-320J FPV Full HD Video Transmitter
Brand: HiDes Technology
SKU: HV-320J

HDMI/CVBS to ISDB-T/ISDB-Tb Modulator

100–2500 MHz

HV-320 is the most cost-effective solution to transmit long range HD video for FPV application with digital TV technology. The video input source from either HDMI/DVI or composite (CVBS) is encoded in 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-320 via the standard coaxial cable or antenna.

Datasheet — HV-320J

04 · DVB-T Full HD Modulator Box

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-320 supports UART data mux feature. GPS or aviation data can be multiplexed in the transmitted stream from HV-320’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 Security for anti-eavesdropping — Support both RF layer and TS data layer encryption.
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. In DVB-T mode, 1MHz~8MHz Bandwidth options are supported.
06 Versatile video inputs — Support HDMI/DVI and composite (CVBS) video input.
07 Easy to Configure — Channel number can be configured with the IR RC easily. More advanced configurations can be set from an external host like PC/NB thru serial port interface.
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 external 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-320’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.

HV-320E supports EN 300-744 DVB-T modulation while HV-320J supports ARIB STD-B31 ISDB-T/ABNT NBR 15601 ISDB-Tb modulation.
HV-320 supports only H.264 video encoding, so the receiver should be able to decode H.264 stream while old DVB-T/ISDB-T TV’s may not.
There could be MER loss in high gain/attenuation level.
Specifications are subject to change without prior notice.
