Hi Guys,

I'm in the process of putting together a proposal for a local company, and need to find more info on transferring video.

The idea (though I can't disclose exact requirements) requires HD video to be transferred from a moving vehicle (generally line of sight, but may occasionally move away from this behind hills etc), back to a computer based in an office location.

I'm wondering how the TV companies achieve this with their live feeds, and if anything is available on a less expensive basis with new or emerging technology?

Thanks for any input you're able to provide.

Local store and forward

In contained moving object areas like racetracks, they put wireless antennas all over the place in a mesh. Data is uploaded, sent back to central location and uploaded via satellite transport or fibre.

Thanks,

Firstly, l need to advise that I'm looking at distances around 5-7km's.

The vehicle could be anywhere within this range (for example a skydiving aircraft, 4x4 off road vehicle, or paintballing teams etc.)

What happens if the signal is lost, does the Tx resume when the signal is re-linked?

For that distance with dodgy terrain, you would likely have a helicoptor in the mix. This is used for the rowing at Karapiro which is flat and limited in distance.  When doing live TV, you might have a wide shot available or at least cut to a commercial break.

If you want to get fancy, go google for helicopter link systems. Transmit aerials that know where they should be pointing to, and will auto rotate to the receiver position. Very neat pieces of kit.

That's great info.

Just found a US based site which sells the helicopter stuff - interesting.

Is 4G capable of fast HD streaming yet? I was considering using a cellular network to send the video, but not too sure if this is cost effective yet.

The cellular range may not be there yet.

Streaming video over 3G is used here by at least one person commercially but I think they bond connections to achieive it. I think Telecom and  TVNZ are using 4G to stream video live so its out there happening. Do you need to video back in real time or is it a near live use?

Real time would be ideal of course, but it would depend on the time delay as to whether the customer could work with it or not.

For example, a 5 minute delay might be workable, but a 15 minute delay would not.

Thanks

Ok in terms of live streaming there are a couple of options for you

Cellular - use the public facing networks, if its busy with other devices you will have congestion. Coverage is a challenge depending on location of towers

Unlicensed Spectrum - Take a risk but lower cost of entry

Dedicated spectrum and licensing - Ensures no congestion, have lots of receivers for diversity reception to give you coverage but higher cost of licensing at least.

I guess you find the solution that fits and include all the running and set up costs for your business proposal

OK thanks,

I'll do a bit more digging around and look at dedicated spectrum pricing and licensing etc.

Thanks for your help guys & have a great easter break.

A bit late....but look into "load-balanced bonded VPN" connections (allows combining of multiple WANs [multiple 3G, 4G, WiFi etc] in order to achieve a reliable high-bandwidth connection to a VPN server). There's plenty of deployments targeted at live streaming video and SAS VPN options available.

Here's a couple:
http://www.peplink.com/technology/speedfusion/
http://www.viprinet.com/en/technology/principle

Your deployment may look something like this:
1x Backpack / Box Containing a small embedded PC and battery supply

The PC could have the following WAN connections:
1x Vodafone 4G USB Stick
1x 2degrees 3G DC USB Sick
1x Telecom 3G Stick
1x Wifi USB Stick

Depending on your connections available to you at any one time your VPN bonding client would establish a VPN connection over one-or-multiple WAN connections to your VPN bonding server which would be configured to reconstitute them back into one connection and forward the video to your desired location.
