digital fpv - 7 kilometres range - 50 ms glass to glass latency - modular design
A Digital Solution
Since when pioneered in the early 2000, FPV has always been dominated by analog video links. While they can provide good latency and range, they also forced a terrible video quality on the user.

Digital FPV can compress more data into the same bandwidth to increase video quality, but usually cannot match latency and range of analog FPV. fpv.blue has been built from the ground up, over the course of almost two years, to be a digital FPV solution where latency and range are not sacrificed.
Very Low Latency
fpv.blue can vary its video latency depending on application. Glass to glass latency starts from 50 milliseconds for 720p at short range and is increased of around 5 milliseconds when going long range, gaining additional link resiliency. Lower latencies are possible at lower resolutions.
Latency Comparison
fpv.blue 50 ms
Analog + FPV camera 20 ms
Analog + GoPro 80+ ms
Wifibroadcast 120+ ms
DJI Lightbridge 150-220 ms
Solid Long Range Link
fpv.blue has nothing to envy to analog video links with respect to range and interference recovery. Several transmission modes are selectable directly from your RC Radio, to control how long it should take for the receiver to reconstruct a complete image with no reference data. This allows for extreme flexibility with just the flip of a switch. The video shows a test several kilometres away, where a turn back was forced by the short range of the UHF control link, while the HD video link was still perfect.
Modular Design
The transmitter is composed of three interchangeable boards. They are for video input and power regulation, video processing and RF transmission. They can be upgraded individually, for example changing video transmission frequency. Four RF transmission boards are in the work, for 900 MHz, 1.2/1.3, 2.4 and 5.8 GHz. The receiver is too, modular, sharing the same video processing board of the transmitter and having slots for up to 3 receivers, implementing diversity.
Small
The transmitter is only 63x38 millimetres, smaller than a credit card and just slightly bigger than your standard analog video transmitter. Weight ranges from 38 grams for the bare transmitter to around 75 grams for transmitter, antenna and camera. A Step-Down regulator is included to allow a direct connection with a 2S to 6S battery avoiding external bulky voltage regulators.
