Tee 0 #1 April 16, 2002 Silly question for you...how does, or is it even possible for, the camera man to transmit live video to spectators?Thanks!tee Quote Share this post Link to post Share on other sites quade 4 #2 April 16, 2002 It's possible.The Golden Knights have used a portable microwave system for demos and live TV shots. Tom Sanders used a microwave transmitter attached to is left foot for the opening ceremonies of the Seoul Olympics.There are several systems out there that I'd like to take a shot at experimenting with, but for the average skydiver/videographer, it's not financially practical for anything other than well funded events like the opening ceremonies of the Olympics or something like that.quadehttp://futurecam.com Quote Share this post Link to post Share on other sites nacmacfeegle 0 #3 April 16, 2002 Isn't there something like a 5-6 Ghz transmitter available for this very purpose, or is the range just way too small?In "Enemy Of The State" Gene Hackman walks into a corner shop and buys a fistful of 'em, or was this just 'artistic license' like certain freefall sequences.....CyaD Quote Share this post Link to post Share on other sites SkydiveMonkey 0 #4 April 16, 2002 It'd be good to see when the price of it does come down, especially from a student / instructor point of view. When you participate in sporting events, its not whether you win or loose, its how drunk you get. Quote Share this post Link to post Share on other sites quade 4 #5 April 16, 2002 Frequency and range aren't the problem.The problem is the cost.I've done a fair amount of research into what would make an acceptable system -- analog transmission is right out because of multi-path and signal fading. The way to go is CODFM.The guys over at KABC have been fooling around with with a back-pack unit that works really well -- non-line of sight -- very powerful and because it's digital there's no ghosting or other crappy signal degradations. Unfortunately, the batteries for this thing weight about 10 pounds and the unit costs about 30k. Fine if you're a news crew or, like me, want to adapt it for live TV shots from moving vehicles (think roller coasters). Sucks if you want to take it skydiving.I know of another system being used by NASA for live TV from EVA packs to the ISS, but well, that's even MORE expensive.quadehttp://futurecam.com Quote Share this post Link to post Share on other sites quade 4 #6 April 16, 2002 QuoteIn "Enemy Of The State" Gene Hackman walks into a corner shop and buys a fistful of 'em, or was this just 'artistic license' like certain freefall sequences.I didn't see the movie, but if it's anything like most spy movies, then the performance they showed out of miniature transmitters bought at something like a Radio Shack was -probably- greatly exaggerated.To do it right, ya need to spend some coin and going down to Radio Shack ain't gonna cut it.quadehttp://futurecam.com Quote Share this post Link to post Share on other sites CameraGeek 0 #7 April 16, 2002 I have to make a point here.In fact, the first live air to ground was (and still is) an analog system designed by an unknown genius named Andrevideo (you pronounce his last name - I ain't touchin' it!).

It's also, as I'm sure you're aware, very picky when it comes to things like being pointed in the right direction and antennas.Heck, even Perris has it's own air-to-ground analog system, but it's very persnickity when it comes to pointing and I don't care very much for the size of the thing either.What I've been looking into is something more forgiving and easier to deal with.quadehttp://futurecam.com Quote Share this post Link to post Share on other sites harro 0 #9 April 17, 2002 Bluetooth technology.If you have a bluetooth enabled video cam and a bluetooth enabled mobile phone you can transmit straight to your web server to be viewed live!!!!Freemind, freesky, freebeer, freefly, freesex Quote Share this post Link to post Share on other sites quade 4 #10 April 17, 2002 QuoteBluetooth technology.I'm hoping that most folks realize that was a joke.quadehttp://futurecam.com Quote Share this post Link to post Share on other sites Tee 0 #11 April 17, 2002 Thanks for the input guys, I knew I could count on you.

Check with the Ted Wagner ay www.omniskore.comDanger Quote Share this post Link to post Share on other sites VideoToaster 0 #16 June 7, 2002 Hello I am currently working with a 2.4GHZ Air to Ground Wireless Video System .The video and stereo audio output is from my Sony TRV20 video and audio out 3.5mm 4 conductor mini jack .The cost of this system is less than a good Sony mini-dv camcorder. You have to have a line of sight from the transmitter to the receiver to get the video signal. The transmitter and battery are in a small fanny pack that I wear on my waist so I can have the line of sight to the receiver antenna. The receiver antenna is sitting flat on my car roof. In my testing I have gotten a very good video signal from exit at 13,000ft. AGL to brake off at 3500ft. AGL. When the transmitter antenna does not have a line of sight with the receiver antenna the video signal will be lost. I will keep you updated on my testing of this Air to Ground Wireless Video System.
