Sky Drone FPV: Long Range Digital HD Video FPV Solution


Sky Drone, a Hong Kong based start-up, has developed a revolutionary new way of transferring FPV video. Utilizing 3G and 4G/LTE networks, Sky Drone FPV is the world's first and only full HD Digital FPV video solution for consumers. The Sky Drone FPV groundstation software automatically adapts video transmission frame by frame to the available bandwidth, ensuring minimal latency. With the Sky Drone FPV groundstation app, users can receive real-time HD FPV video straight on their own Smartphone or Tablet.

Users have the option to connect the Sky Drone FPV hardware to a MAVLink compatible Autopilot Board like 3D Robotics APM. A Head Up Display (HUD) will be rendered on top of the live video stream, providing the pilot with real-time telemetry.

A unique feature of the Sky Drone FPV is the possibility to take 5 megapixel high quality still images during flight. The images are transferred to the groundstation app while the video keeps running uninterrupted. The Sky Drone FPV is not just limited to aerial vehicles. It can be used on ground vehicles and any other use case where real time video transmission is of benefit.

With Sky Drone FPV a new era of FPV is here! For more information, please head over to our Indiegogo campaign: http://skydrone.aero/fpv-indiegogo

Great work! Any plans to incorporate control via same link or is skydrone solely for video?

Cheers,

Hi Wolf,

thanks.
Currently the Sky Drone FPV is only for video. As the hardware would technically allow full control as well, we might add this as a later software update. It is not our focus at the moment however.

What happens when there are issues with multipathing or other signal integrity issues? Does the video stream go all "blocky/pixelated and freeze until the frame buffers are freed (as we see on digitial TV)?

That's why we use our own proprietary video codec: other than solutions using standard codecs - which are not optimized for live video transmissions - like h.264, our codec won't freeze. It is much more robust to errors and can automatically and instantly adopt resolution, compression and frame rate to new circumstances to always provide a snappy video stream.

Excellent! THAT is essentially the only way forward for digital FPV to work, so I'm glad to hear that is what you've developed.

Is there any reasonable way for you to measure "glass to glass" latency?

Our latency measuring setup was: having a fast timer with millisecond accuracy filmed by our FPV camera. Then we took a still image with a DSLR on a 1/4000s exposure of the timer and the tablet showing the video of the timer in the same frame. The difference between the visible timers is the latency.

Interesting. Latency of a data cell network for applications like Face-time is in the order of .5s. you need to add the cellular network delay to your latency factor

The latency depends on many factors and the network latency is only a small portion of it. The biggest part is usually due to codecs that are not optimized for the use case. As said, we get a typical end to end latency of less than 150ms.

I live in Costa Rica. We only have a saturated HDSPA network, do you think it would work? You have to remember that not every country has telecom infrastructure such as US/Asia/Europe

I wonder if it's possible to get a special connection status through Verizon or AT&T that allows less latency?

It seems like it's very possible, through their software, to assign incoming and outgoing data different urgency levels, that essentially allocates more resources quicker to higher importance data requests....

Yes, it will work. As the system automatically adapts to available bandwidth, you will probably not get full HD resolution though.

Send me one and I will test and review it!

As our Indiegogo campaign indicates, we are in the funding stage. Feel free to contribute - every small amount helps

Interesting. I guess I'll believe the cell network latency when I see it. But what happens if you lose cell signal? Is there still a direct video downlink? Is it possible to use this HD video system without the cellular network at all?
