I'm bumping this up to see if anyone has real-world experience with JAP 3G on bigger screens? I haven't ever used the product, but have pulled out plenty of 2G and 2G+ hardware to replace with HDBT over the last few years, and the picture quality was always significantly better with HDBT. I'm working on a project right now where the client wants to distribute 4K DirecTV, but he's not going to be happy if the distributed picture is a clear step down from what he is used to wth local sources.

we used the 3G on a point to point system on a 75" XBR and the DTV signal on ESPN looked pretty bad.
I have been told it was a firmware issue, but by the time I was told this I had already swapped out the JAP gear for a HDBaseT solution.

At the same house we are using a point to point JAP 3G setup on a 55" XBR and it looks fine.

My issue with all HDBaseT solutions right now is that they are all 4k Lite and not full 4K.

JAP is a compressed system, it is NOT bit for bit. HDBT (and other 'extenders' that are point-to-point) are bit for bit.

No one knows just how much compression it uses. But it is noticeable on large screens and people who are discerning on high quality pictures.
That said, the majority of the public (90%+) will never notice the compression. It is fine for most all video distribution and budget display systems.

I take issue with someone using it on a high-end system however. Where picture quality is most important and the customer has invested in top quality displays or projection. But a lot of dealers do it anyway; either out of ignorance or just not giving a shit. But it's not my work, so that's none of my business.

Crestron 4K fiber. They have a few different solutions, we have used several of them now in large commercial jobs using 64x64 matrix switchers and they have been excellent. Not cheap, but they do what they say.

Just
Call us (727-517-4053 Ext 1) and ask for a 3G demo kit. It will cost you nothing to see it working great with DTV 4K.

The problem with 2G was it didn't support interlaced and too many users couldn't grasp how 720p/60 was a better video signal than 1080i/30. 3G does support interlaced, HDR, and everything else on the market.

Not only hilariously expensive (the 4K fiber solution) and overly complex (outboard card chassis just for the fiber tx/rx), but it still doesn't support data rates over 10.2Gbs, i.e. no HDR, 4K/60 4:4:4, etc.

Extron's Fox Box for the win here!!

That's disappointing. They should be able to pass 18Gbs over fiber. They might be using the UTP chipset and converting over to fiber. Come on Blue.

What I've ascertained so far:

UTP = HDBaseT = 10.2Gbs = many 4k resolutions but not full upcoming 4k spec including all color space specs (though there is no native sources with these specs yet!)

Fiber = full 18Gbs that can accommodate full 4k spec (maybe, double check the spec)

YES!!!
Always look Native Bandwidth Number, anything else is a sham. There are a lot of older platforms that are about to be obsolete and these companies are trying to get off of their inventory as quick as possible. You will see "4K" plastered on damn near any and everything now. Again ALWAYS ALWAYS ALWAYS check for real bandwidth.

I am really hoping the Atlona AT-CENT-301-CEA solves some of this for me. Its $1500, but when my usual extenders cost $400 for a pair, the premium for my clients who want 4K shouldnt be too bad an upsell. 4K projector systems have really only been the issue in the field on my end, and having to scale-back the color settings on these new UHD Blu Ray players.

Win??? Below is a link for the Fox Box product I found on the Extron website and like everything else it also has a big "4K" logo on the top of the product page, but specifications seem to indicate it can only do 1920x1200 1080/60 resolution which is in no way 4K.

Does Extron have another product that's full 4K/60 4:4:4 (18Gbps)?

This is an interesting product because it has all the feature I'm looking for (4k@60 4:4:4, Ethernet, RS-232, IR, POE and digital audio), but to accomplish this over a single cat cable they are employing compression to the video signal.

It's stated as Centum 301 CEA visually lossless VESA Stream Compressiogn (DCS) which is a 1.5:1 or less "light" compression.

Like many other products in this category, doesn't look like it's shipping yet :(

Hi Brent, I've been in touch with Zak about the new VELOX active fiber cables and he's stated that they aren't in stock yet, but may be available soon.

He's also mentioned that a dongle is required in addition to the connector on each end of the fiber cable which in his words "makes it all happen".

The website doesn't seem to mention this addition dongle... can you offer a more intelligent explanation on how the cables work and what parts are required?

Knowing expected availability would be helpful too.  I'm looking for a solution that I can obtain and put in place in the next 1-2 weeks.  I trust your products, but if lead times will be longer than this I'll need to look for an alternative solution.

Thank you,
Paul

Gotta love sales guys....
The dongle repairs the issues that are inherit with in the fiber system and there are several. You guys know the drill there are only a few fiber mfgr's in China so the same fiber we sell others sell as well, but they are only DPL Certified to 100' we are Certified to 330' because of what the dongle does.
Now it would be possible for me to have the changes made within the Fiber Headshells, but that would also fix my competitors products and I am not spending my R/D dollars to help their sales.
The dongle is only needed at one side and comes with the Fiber System it is about 3 inchs long and is passive.

The only delay in lead time is the size redesign I did on the dongle based on CEDIA Feedback. Call me on Wednesday (I am out Monday/Tuesday for an Old Mans cancer test), I may be back in the loop by then (or maybe not).

Here you go. [Link: extron.com]
