HV-320E FPV Full HD Video Transmitter (100~2500Mhz), HDMI/CVBS to DVB-T

Description

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.
*
HV-320E supports EN 300-744 DVB-T modulation while HV-320J supports ARIB STD-B31 ISDB-T/ABNT NBR 15601 ISDB-Tb modulation.
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 an HV-320 via the standard coaxial cable or antenna.
**
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.
Features
High-Performance Wide Frequency Rage Support
Direct digital conversion to 100..2500 MHz for excellent signal quality
Professional grade modulation error rate (MER)
Flexible Bandwidth Option
In DVB-T mode, 1MHz~8MHz Bandwidth options are supported.
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.
Security for anti-eavesdropping
Support both RF layer and TS data layer encryption.
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.
Versatile video inputs
Support HDMI/DVI and composite (CVBS) video input.
Easy to Configure
Channel number can be switched with the IR RC or onboard push buttons easily.
*The channel list mapping is user configurable (channel number -> frequency/bandwidth)
More advanced configurations can be set from an external host like PC/NB thru serial port interface. UART control protocol and API/SDK available on request.
Optional LCM configuration tool (HL-100) is also available.
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 kilometers 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.
Daisy-chain Connection (Bus-Topology)
Multiple HV-320’s with different channel configurations can share a single cable. It can dramatically reduce cable deployment cost and effort.
Real-time protocol and Low latency
No frame drop in QEF (Quasi-Error-Free) condition, and low transmission latency
*With HV-120/HV-110, the latency for 1080P HD is about 250mS
