Send video signal "wireless" to HD field monitor

Hi,

I´ve had this question several times now, ... and was wondering whether anybody of you guys had a solution which would fit my needs and of course my wallet:-)
Clients are more often asking for a wireless signal sent to our HD field monitor. Normally I would be doing that with HD-SDI cable connection but I was wondering whether there was a wireless solution? I´m sure an HD wireless solution is very expensive and was wondering whether you would then just use a PAL/NTSC signal?! Does anyone has any experience with that? Thanks, E.

since HD in computer is only problematic when it is hitting the disk, you should be able to capture and transmit by ethernet.
Such setup does not exist, but you should be able to have higher resolution than SD.
but you will have a huge delay, between source and player.

Hi Emanuel,

I know your problem. For today's customers, everything is so easy an cheap and wireless video transmission is as easy and cheap as a wireless mic.
If the wireless resolution is just for preview, maybe SD would be o.k.... Try one of these 34,95€ video transmitter from Hofer or Lidl. Maybe you should add a 2.4Ghz biquad antenne for a better transmission.
Oh, before i forget: JVC has announced a wireless HD solution for live-broadcasting. Price inclusive camera should be about 25.000. Camera only about 10.000.

Or this one from IDX-Technology

You can mout it right away on the back of your camera.

IDX CamWave

I guess it's going to cost more then a system from Hofer or Lidl! ;-)

Cool thing, yes. Thanks for that.
However, I found a website which says that IDX doesn´t produce them any more and that a new model should be released in late 2007. This new model should be SD/HD switchable.

anyway the one from IDX says nothing about HD, it is just SD.
that is was describing upper. you convert the video to mpeg signal (with a PC or anything else) then to ethernet, then to wifi.
IDX annouce a delay of less than half second (that's already huge).
some multimedia box can display an HD signal from an ethernet connection, so they could make cheap receiver.
You need to find a box than can encode HD on the fly.
stangely, lots of chips must exist for such purpose (after all there are dozen of HDV camera models doing exactly this, encrypting an HD signal to mpeg2)
but you can hardly find any standalone, reasonably priced box on the market.

There is an opening for business here. Cheap converter taking HD-SDI/HDV-firewire to ethernet and reverse.

Range

Hi Ivan,
Do you use a CamWave?
What about range?
And the quality of the signal at the monitor?
Thanks,

Gérson

Hi Gérson,

No I do not use CamWave. So, I can't tell you anything about it. Sorry!

Greetings.

Hi, the range is great, I did an outdoor concert last week and the camera had a stable signal to about 1200 feet, indoors its dependent on the number of walls, but easily the best system I've used for the money

You might look at the LinkHD. It connects to our HDSDI port. I've been over 600 ft away without a glitch. The only drawback is that its a power hog. Our Anton/Bauer batteries only last about 30min.
