Wireless Video out solutions to field monitors

I was just wondering about wireless video out solutions. I've seen wireless DVI dongles available and I presume that a HD-SDI to DVI could be used out of the camera to this and then have the receiver plugged into the field monitor. Is this a viable solution? And are there better ones? One less wire hanging out of the back of the camera is always a plus as far as I'm concerned, although it'll obviously have an impact on the battery... any thoughts or suggestions?
 
100m+. modulus or transvideo at traditional 35mm filmshootings are low quality and cover distances between 30m and 300m. most situations can get covered with a radius of 100m imho. wireless video preview saves also a lot of shooting time beside the other benefits. more simultan receivers would be perfect - one for director - one for gaffer - one for art director another one for videoassist.....
 
If you're going to get in to wireless video. How about 600' non-line of sight. Audio and Video sync with less than 10ms delay. HDSDI TX input and RX output, with multiple channels/freq and no FCC license required. Give me a decent timeline and I'll pre-order!

Just continuing a process of constant re-evaluation of RED in a total production system.

There are some interesting new technologies out there, but distance and image resolution pose significant challenges.
 
If distance is an issue Stuart what about bridging the wireless connection with a booster? So for example the typical setup had a 15ft/5m range but if that wasn't enough you could put a bridge in and boost it to 30ft/10m and so on. Of course it would put a delay on the system but it would fit with Red's modular concept, if you need more you buy more. For monitoring purposes I'd like to be able to view 1080P or 720P at worst, the currently available monitoring/tv solutions would fit with this nicely and open up a range of options for individuals from a low to high budget.

Even if the director is only 15ft behind the camera it's one less wire to be attached to the RedOne, and gives the cameraman the ability to be independent of other equipment - The staircase fight from the latest James Bond springs to mind, I saw in a documentary it took absolutely ages to shoot it but it struck me as being something very easy to do if the camera man was independent using a focus puller on a remote system such as Curt's.

The bridge device itself can then become a problem of course. To what does it mount, how is it powered etc ... nonetheless good ideas, I agree we should look for a solution at 720p HD minimum rather than SD downconverted.
 
I would be very interested in some sort of wireless tap, too, especially for Steadicam work. Even when shooting locked down and on location I think it would be very beneficial. I personally don't think 600' is necessary (was that a joke? That's two football fields!), but even 30-40 feet could prove to be helpful. I'm not huge on accessories, but this is one I would invest in.
 
Eh, I know the RED guys are sick of this, as I ask for it every time; but this is where I'll once more mention my request (in vain) to have a regular analog composite output available in camera too.

Stuff like transmission for framing and action monitoring for the Director is just SO EASY, and 90% of the time totally adequate, with basic composite video. Analog composite is not dead, or even out-dated, not by a long shot.

Under current FCC regs, this doesn't seem particularly likely to me.

When I provided the wireless equipment for Rockstar: INXS, cast members we're allowed to roam a very large piece of property in an area of Los Angeles, directly in the shadow of Mount Wilson. Lot's of signals in the air before we added our 6x channels of 5.8ghz digital microwave sending the SDI w/embedded audio signal to video village, sometimes 800'+ non line of site, through brick and concrete.

600' with all the qualities I mentioned before make it iteresting. 1.5 to 2-miles LOS (w/o FCC) means it can compete with some of SD stuff already out there.

We also sent a wireless T1 signal several miles with all 6x SDI and audio streams encoded in nearly real time (about 7-8 seconds of delay). Producers in a studio on the other side of the city, and executives on the otherside of the planet could watch everything that happened live. All without the camera ops being cabled.

Can't RedCode not be used to create a compressed 1080p signal that could be sent using Wifi? draft 802.11n appears to be able to deliver a 270mbps signal, that's 33.75MBps. In theory that's about enough for 4k RedCode RAW although in reality I'm sure this would present it's own problems, but surely 1080p RedCode RAW must be in the region of 10 - 15MBps if not less, is this not a viable option Stuart?

If the RED guys are sick of this or not, I don't know but I can assure we the customers don't!

I fully agree, for monitoring (steadicam, for instance, and not only) it would/will be quite useful and practical.

That's something so obvious that I hadn't even spent time thinking about, but I'd have to put my vote in for such an output, too. Even though the camera is a 4K acquistion system (and even the "bottom end" is 720), having the ability to plug in and playback on virtually any monitoring system in the country (whether SD or not) shouldn't be overlooked. Even if it's just for framing or to doublecheck something of importance in the frame, that should be possbile in a pinch.
