HDMI transmitters – short range for consumers + homes

[Wolf Seeberg]

HDMI transmitters

Short range for consumers + homes (cheap) [ I do not sell anything of this stuff (no margin)]

Older ones have a .5 sec delay, new stuff has 1-5 msec delay. There are about 20 gadgets like this on the market Don’t buy anything that you can’t return!! I started a collection of links, I have no recommendations on what is best. The Robert Benson guy in San Diego in this list may be a good source. If someone really digs into this let us know. Remember HDMI connectors in a professional setting will cause severe pain. The terradeck uses the same wavelength 5.2-5.8 but different way of Tx. it has the same problems this stuff does: (range, reliability, HMI lighting). More on Tx in general read my previous post.

Robert Benson. 619 733-9327 robert@robertbenson.com photographer in San Diego sells HDMI pakage very reasonable $ 650 with batteries etc.

Nice videos, 10 day warrantee, he admits to being a garage outfit and seems like a straight ahead guy (most other folks that resell a package like this pretend they are Archimedes and invented the sun) watch his videos:

http://www.ebay.com/itm/Wireless-HDMI-monitor-/290572485418

FCC ID number is BGAACA300T.

Here the HDMI video link

This is the 2.4 analog composite video link

http://vimeo.com/16487451

The wireless signal is transmitted in real time with no lag (almost none… there is a one milisecond latency, which is barely perceived by the human eye). The transmitted signal is 1080p with a data rate of 3g bps. On some DSLR cameras, like the Canon 5dmk2, the hdmi output from the camera is dropped from 1080p to 480p when the record button is pushed. During this time, there is a 3.2 second black out on the monitor as the HDMI monitor reacquires the downgraded signal and switches to the lower resolution.

 

Robert does not seem to use the Liliputs anymore. Do not use this monitor:

LILLIPUT 669GL-70NP/C 7" 16:9 LCD MONITOR WITH VGA/HDMI OR DVI INPUT

3 big problems with above monitor $ 200:

1. The menu is responding to commands very-very slow

2. The screen aspect ratio has 2 settings only 4:3 and 16:9, not Enough for HD pictures.

3. Not Enough signal formats, work only with some cameras

Generally there is a good reason why Liliputs suck. Note that most these monitors generate RF and ruin the range (sensitivity) of the Rx if nearby.

HD FLOW

 

HELLO FOLKS, BY TYLER CARTNER 10:05 AM ON DECEMBER 14, 2010

http://endlesspicnic.com/blog/2010/12/hd-flow-wireless-hdmi-5d7d-wireless-monitor-solution-on-the-cheap/#more-572

 

We recently saw this little HD wireless kit on Markertek’s web site and thought it might make the perfect wireless field solution for the 5D on the cheap. We ordered one and tested it. We thought we’d save ya’ll a little time and talk about the pros and cons.

HD video transmitted almost instantly through the air for under $400!? Yes indeed, and the image was pretty good too. It was re-compressed on the fly (h.264), but damn if it wasn’t fast at 30ms and the image quality was very good with the exception of some artifacts when the image got busy. We tested the range to about 100′ and it held up. Certainly it would be usable as a director’s monitor. But, and there is a BIG BUT, when used with the 5D, a problem comes when you hit the record button; it takes the unit about 13 seconds to re-handshake the HDMI signal and put up the image. We wouldn’t be able to live with this delay in a production setting, but maybe there are those of you who could. We were able to get rid of the delay by sending the signal via the composite output of the 5D, but of course the image quality is much lower and you lose the ability to also output over HDMI from the camera, damn.

We were dying to test the HD FLOW with the 7D and a friend of ours was gracious enough let us borrow his. The HD FLOW works beautifully with the 7D! Since the 7D doesn’t change resolution when the record button is pressed, there is no wait time, and the image stays up!

Here is a summary of the pros and cons of the HD FLOW when used with the Canon 5D:

PROS

30ms delay, almost instant video!

Image quality decent enough for director’s monitor, Possible to have up to 4 receivers, Instant image when using composite out

Good solid range of 100′ or more, Runs on batteries or A/C

CONS

Image showed artifacts when there was a lot of movement

Delay from the time you push record on 5D is about 13 seconds

Cheap plastic construction would certainly be challenged in a production environment, HDMI handshaking a bit unreliable

This could be a great solution for the 7D, but the 13 second delay makes it impractical for use with the 5D MkII.

Here is a link to the unit on Markertek. We are not affiliated with them in any way.

Optitek had a genius gadget at CineGear:. They have a modified lens mount for the still Cannon lenses that let you focus the lens with their own internal factory electronic motors with a remote wired focus control. Now you can buy cheap cameras and focus cheap lenses professionally. WOW (also not on their website.

Also at CineGear 2011 was but did not see it myself:

Heard that Tx placement is critical which appies to all these units as their power is very small. With attention and knowing their range is small they can be usefull on small stages or small houses. The sales people here make claims that they develped this, its hard to brlieve that since they did not even pay attention to the standard fim and video 10-30V supply. Ed.

Mfct Dan Kanes says: available July 1 ? Full 1920x1080 10 bit 4:2:2 HD. Up to 320 feet line of sight and up to 200 feet through walls. Less than 2 MS Latency. It requires 5V Power on either side to run. We include One D-Tap Power supply which also could charge your Cell Phone or iPad from a D-Tap (aka P-Tap port). The receiver side also requires 5V power and we have a bunch of recommended 5V USB batteries that are not expensive, or you can purchase an additional D-Tap to USB power cable with an appropriate receiver lead. We do include a powertap regulator cable in the package. Affordable at $1199 MSRP.

Biggest downside: it's HDMI in and out. Even they're suggesting "just go get a Decimator 2 if you need HD-SDI to HDMI", and they're right. To build this wireless HD kit out right, you will spend another $495 for a Decimator 2, AJA HI5, Atomos Connect H2S (for $349 when it ships), etc. Likewise, you'll need an AJA HA5, BlackMagic HDMI to HD-SDI on the receiver, Atomos Connect S2H (for $349 when ships). They claim to have operated 6 systems simultaneously. Emitter draws 0.1, receiver is 0.2 amps. No timecode passed. This is AES 128 bit wireless encryption, FCC permit?

$995 + $495Decimator + $495 Decimator = $1985 (plus tax?).

I spent some time with these guys at Cinegear and at the Stabilizer Gear Expo. While I was originally not interested in an HDMI solution, I've since found out that the upgrade to my monitor (Cinetronics) will have HD-SDI to HDMI conversion built in. So, at this point, the biggest problem for me is the time it takes to reconnect the transmitter and receiver once the signal is lost (7 seconds). If they can get this time down, I'd consider one.

[William Demeritt]

I've got a Paralinx Arrow on order, planning on using it for a job on 6/21.

 

The reconnection time might improve with the software updates, but I'm not really sure. Personally, my approach to that issue is: it draws only 5 watts, so connect it to a battery that'll run it all day and never power it down. Boom, no need to reconnect.

[Jess Haas SOC]

The problem is that when it loses signal(which will happen) it takes a very long time to reconnect. From what I saw it seems that their stated reconnect times are actually best case when you are within arms reach. At a distance it was taking way too long to reconnect. I can't say how often you will get disconnections in real world use but as is its a bit of a dealbreaker for me.

 

I would not expect any major changes(such as a quicker connect time or hd-sdi) to this product that aren't updates to the amimon reference design.
