To give you an idea of what is available at the moment up to 2000 feet and 1 ms latency, Paralinx Tomahawk started at $6995, now I see its $4300..
Will be very interesting to see what DJI come up with, and to see if it really is uncompressed (I cant imagine it will be) but who knows, times are changing.

 

[maxwelltub]

For zero, or close to zero latency I dont think you can compress it. I could be wrong. Anyway this looks like an awesome product.

 

[Benjamin Kenobi]

That....is....awesome! It will revolutionize the industry! So many industries are looking for live HD feeds. This, combined with a new generation of battery technology, will give us incredible capabilities!

That's why it will be interesting to see exactly what they have done, there has to be some new implementation here to transfer HD at this distance, maybe using wimax or something.
Just hope it will be legal in most countries, not sure I would buy version 1 of this thing, especially with DJIs record of fixing things after release.
Transferring HD over a long distance is no mean feat.

 

[Tahoe Ed]

I agree and it not just HD it is RC combined.

 

[maxwelltub]

Ed, can you explain that RC/ video combined thing?

 

[Benjamin Kenobi]

Ed, can you explain that RC/ video combined thing?

I think post #2 best describes it.

 

[Tahoe Ed]

The RC control and the HD video link are over the same 2.4gHz channel. You can control the copter and the camera with a second Tx all together.

 

[maxwelltub]

Ya I saw post two but its in a different langue. I'm not sure how that isn't a risky thing to do?

 

[Benjamin Kenobi]

This is all pre-release stuff. No point in asking real questions at the moment. DJI will release the specs when they are ready.

PS - What's the risk? Video on one channel set and RC control on another set. It seems safer than having two competing systems.

 

[maxwelltub]

No point in asking questions? really? Ed might know the answer as he is DJI forum support.

The reason I am wondering about the 2.4 video and transmitter is because you would not use this set up in any other circumstance. Perhaps if they are using the same controller board it can make sure to prevent interference between the video RX and controller TX?

 

[eyeball]

I was looking at this new product Lightbidge as an app on a phone this afternoon, seems very interesting, its early days but I'll keep you updated.

When when when and how much.
I'm using the 5.8ghz boscom rc805 system now and would like to upgrade to a better system asap.
any advice on better system be appreciated please.
Thanks

-Support for two remote controls: one for flight control (10 Channels) and the other for gimbal control (6 Channels). Control signals are received in the air and then transmitted to the flight controller through D-BUS.
-When used with a non-2.4G radio transmitter, video only transmission operation is supported. The DJI 5.8G radio transmitter is recommended.


Strong Anti-Jamming Technology
-Frequency Hopping Spread Spectrum(FHSS) + Direct Sequence Spread System(DSSS) technology is used for uplink transmission to enhance stability and offer anti-jamming capability.
-MIMO multi-antenna technology and OFDM modulation methods along with advanced algorithms are utilized for downlink transmission to enhance data bandwidth, improving dynamic performance and increasing stability even in harsh environments.
-Channel interference is constantly monitored during downlink transmission with automatic switching between 8 channels for the best possible signal.
-Up to 8 downlinks can be connected for parallel streaming and work independently without interference.

Low Latency Transmission
Maximum latency of up to 80ms

Built-in OSD (On-Screen Display) Function
-No additional equipment required for OSD functions when used with A2/WooKong-M/Naza-M V2 flight controllers. Flight parameters will be displayed onscreen.

-Phantom 2, with DJI 5.8G radio transmitter.

Multi-device Operation Mode, Stable and Reliable
-A single air unit can transmit to multiple ground units sending video to multiple screens. (Only one of the ground units can send a control signal while additional ground units will only be able to receive a video signal)
-Encryption ensures only authorized devices can receive data which can be programmed via mobile device software.

Built-in High Capacity Battery
-Ground unit has a built in high capacity 4000mA battery offering up to 4.5hours of use per charge.
-Rechargeable through the supplied charger or via a 3S~6S Li-Po power battery.A full charge takes approximately 1.5 hours.
