Last night, I was browsing the internet in a post-Steadicam day daze (lots of lock offs, so my brain needed to soak some new info), and came across a newer technology called WHDI. Simply: HD wireless sharing (broadcasting/receiving) from an HDMI enabled source to an HDMI enabled receiver. Then, I discovered this company AMIMON's newly announced prototype for their "WHDI Stick".



Reviewing the technology, not just of this "stick" but also of the AMIMON chips themselves, which has a proposed 100 foot broadcast distance (I think they're assuming that's with walls and obstructions) and approx. 1ms of lag. The devices themselves seem to utilize dynamic frequency selection, so the chips themselves will already try to fight interference. Also, they seem to require 5 volts at 2 amps, and an estimated street price of the "stick" is $150 (nobody specifically says for a pair, or per stick, or price difference in tx or rx "sticks").

I'm sure it will require getting the actual devices for testing in our applications, but some operators have previously said that for their needs, wireless monitoring and video solutions need not go more than 100'.

Assuming you can build some custom wiring for your sled to power the device (LEMO to mini-USB with a voltage regulator to give 5v out), I'm wondering if this is a good solution in the near future.

Wiring: $200 (estimating and being very liberal)
2x WHDI "Sticks": $300
Decimator 2: $495
AJA HA5 (HDMI to HD-SDI converter): $490

TOTAL COST: $1,485.00 (before tax, based on approximate values)

Price comparison of uncompressed HD transmission solutions:
WHDI Stick based solution: $1,485.00
Titan HD Wireless: $11,502.97 (more range of course)
CamWave: $5,298.00

Just thinking out loud, but it seems like an interesting possibility. What are your thoughts?

I think is good news because AMIMON are the hardware company
of IDX CW-5HD Camwave HD wireless transmission system
that also came with the WHDI technology.
If the two converter (AJA and Decimator) have not delay for conversion,
I think total combination are very interesting.
