HDMI/HDCP options - Page 2

Don,

Thanks for the clarification. I didn't mean to mislead anyone.

Man, the nuances of these things gets deep sometimes!!

Greg,

If you're talking about the main chip on the board (all the identifying markings are ground off all of the chips) there no way I can solder on it. The solder points are way too small for my skill level and soldering tools.

Moome's HDMI card has a daughter board with many components for the gamma circuit.

If there is such a thing, I guess I could wire up a mini 3 stacked pot in place of the 3 resistors that Moome suggest changing, but I'd really rather not. I paid almost $400 for this card. I would like to think I could get the gamma fixed without having to do it myself.

i have full spec for SII907B.
the resistor for 907 can not use for gamma, it is only for adjust the max output current ( the white level into double terminated 75 ohm). and the 907B its self can not drive long cable, longer cable will degrade signal quality. that's reason why my pervious dvi box is softer than internal card!

Holy Crap Phil!
I was just scrolling down thru the posts and i got slapped in the face by yours!
Scared me there for a minute.
Hope Moome got it too.

I'd like to know this too. He tosses around all the testing he has done and the huge differences between his DVI solution and other HDMI/DVI solutions, yet the only time I was able to compare his to others, I did not see this huge difference nor did others present, and we did not see massive shortcomings of others compared to his.

So, I would really like to know what others he is talking about. My suspicion is the other was moome's external DVI which as moome has said is soft. I have a suspicion that Greg is basing his evaluation of all of them on this one device most likely in a non-optimal configuration. I personally have 2 externals that perform significantly better than the old moome box and compare quite favorably with Greg's product for 1/3 the costs. So, I would like a run down of every external he tested, the configuration it was tested in, and what the short comings were.

.... not to mention that the HDfury doesn't ship until tomorrow, so there's no way he could have tested it.

Using the words "I tested them all" is a very dangerous thing as things change obviously!

Hi,

Sorry been overloaded today. I scanned the base design for the 907B at lunch.

Sorry for the large size.



This original design needs some updating because it was not optimized for 1080p more designed for 1080i, 720, 480p


The R6 412 Ohm is responsible for Impedance Matching. If you have a ring or reflection, which can happen, adjust this value.

The original Gain / Gama ( Gain affects gamma on a CRT) .. R2 150 ohm adjust this value.

On the original design they used two ( C30- 35) 22PF with a ferrite. The ferrite is still a good idea because it limits interference coming back into the chip. However two 22 PF caps have too much DE-Peaking for 1080p.

In other words if you have Ring you need to add a higher value. To much reduces the sharpness. This will not help some projectors, like barco the ring is caused internally and putting large caps will eventually get rid of ring but will substantially degrade the image.

If your going through cables most manufactures tend to get rid of the caps. This is bad because the reflections and ring are too great causing shadow and loss of clarity, a balance is needed.


Also the original SIL907 R7 and R8 that feed the power at 1080p cause noise and HDCP handshake issues. I move these 10k values up to 75 ohms. That makes the 1080p picture more stable, have better focus and less bit drop.

There are a couple of other things that I recommend to make the picture better on this chip but I don't have my book with me today.

Greg

Moome isn't big on returns or exchanges. I've been thru this before with him. I'm pretty sure he saw my original request but chose to ignore it. If he allows me to exchange mine it sets a precedent for others. That could result in a lot of gamma card returns. So I figured my only chance of getting a response was to scream a little.

Will the squeaky wheel get the grease? I sure hope so.

sorry, i have not notice your post last night,
i can accept update no problem,but i have not figure out the cost.by the way, the 150ohm of 907B is for 8bit current DAC output reference,
larger the current output level will only enlarge all the video signal >0.7Vp-p.

Let me guess...
you return your HDTV and PC back to Costco for an exchange every time a new model comes out?








Your squeaky wheel is so loud, you should just threaten moome to send you a free card every time he builds something.

The cost? I've only had it a month and it doesn't work right!

That's F'd up! I want you to FIX it, not update it!

I have a story about my previous dealings with Moome. It's not at all flattering. I chose not to bring it up, but you're pushing me into a corner here Clarence. What do you want me to do?

sorry, i mean every one bought my card can have update, your case is special. i will change new for you! do be so mad

Greg I read on the hd fury site somewhere .cant remeber where, but they have added a 5 volt input for an external power supply. Some one else chime in if they seen this on the site also.

Athansios

I'm going to look for it now......

Found it !


Hope this helps

Thank you Moome! I greatly appreciate it. I'll get the gamma board shipped to you tomorrow.

you are welcome, i am not intend make much money on these card, i only want to let CRT projector to accept good HD signal. more and more HD source are in themarket, and all of them have HDMI YCbCr output , the DVI RGB mode is just a option and sometimes have black level problem when convert from YCbCr, that's why i recommend using YcbCr mode for HDMI.

What's he saying? Use the component instead of the HM if you can? Or HDMI YCbCr istead of HDMI RGB?


Where does one get the 5V supply for the HDFury?

My understanding is that a simple +5DVC wall transformer will do. There's a plug on the side of the HDfury that you can see here:



Kal

I am using the Greg E DVI mod for my Barco with outstanding results. The blacks do not get crushed and there is no need for the external black box connection on port 3. If any member in the NY & N.J. area would like more info and set up assistance you can email me at vectorscope2000@yahoo.com

Forum digging 5 years back!

But that's because I am a late adopter of HD if there is one. I have a Cine 8 and since I am moving my HT to another room I thought I'd finally get into HD as well.

The main question is: do I need any of these items? Can I not just connect the YPbPr output of a media player or bd-player to the pj's BNCs?

My understanding was that that all (incl. component) analog outputs have been Panasony-limited to SD, f/ idiotic copy protection (as if we are idiots and would copy bd's as we used to vhs...). Is that the case?

Is HDCP transmitted over YPbPr? If yes, does it mean I might as well forget playing retail bd's?

I understand ripped bd iso's are rid of HDCP, right?

A lot of questions and if you do some browsing on Curt's forum then you will find most of the answers. First, you need to decide on your source and then go from there.

Here is something that will be right up your alley.

Good price too

With all this going on in this thread doesnt one ask them self that it may be time to go digital?

Probably some, but a Fury or Moome isn't to bad if you already have a pj installed.

Wow, didn't this thread blow up fast? And they say the CRT forum is dead...

Will do my research as recommended, but it looks like specific source(s)' choice (which will certainly include a media player) will depend on options I have as to inputing the signal. If YPbPr from the source is as good as an internal card from Greg or an external one from Moome, then I just need to chose a media player with YPbPr out (and save me some money). Otherwise I can go with one with HDMI out only. If HDCP does not apply over component, maybe I can use a HDMI-to-YPbPr converter (in between cost). If HDCP is an issue with YPbPr as well as HDMI (or with YPbPr straight out of an HDMI signal), then I need one of these cards (assuming they get rid of HDCP issues).


Thank you for the link. Wallace certainly knows his beer!


Do you prefer the picture from a highish-end digital pj? I am seriously asking the question, as I am still where I was many years back, except for a disappointing viewing of a mid-range HD dlp a friend was considering 2-3 yrs back. DVDs were appalling, BDs very grainy. Sharpness, etc in BD not better than mine with DVD (plays from a Dune F).

This question has been beaten to death. CRT still beats digital in on/off cr and motion resolution. If those two traits are important to you, then stick with CRT. If you are thinking of switching, then check out the JVCs. Could I live with a JVC RS45? Yes, but I am not willing to spend the money on one. Since I have a couple of 909s and a G90, I don't have to make that decision yet.
