Barco HDMI/DVI-HDCP board that replaces Port 3? - Page 2  

post #31 of 468
Hi John, that is a great little board you have there. I'm very interested in picking one up once Blu-Ray/HD DVDs come out. I might even be interested in one sooner if I upgrade my trustly old RCA DTC100 DirecTV receiver to the new MPEG4 Tivo box that is rumored to come out early next year.

I too would like to know if a HDMI version will become available and if an internal version is planned at some point in the future.

I was looking at the French forum and came across this picture of your workbench. You have great hand skills to be able to solder those tiny surface mount items with your bare hands like that!

I quite suprise to see my SONY IFB-DVI workbench picture here (in fact my home living room table :D ). Ah yes, I remember, this was some months ago when i've started to build those 30 IFB-DVI for Sony owners ...

There will not be a HDMI version since, this DVI-D module already work fine with HDMI players (it's just a question of cable type, and "voilÃ*").

Yes, about those tiny SMD components, but now I use a binoccular 10X magnifier equipment to keep my eyes safe ...

Is it possible to locate the unit near the HDMI player instead of bolting the unit to the back of the projector if one was to feed it the 30V by some other means?

I ask because my conduits to my projector are not large enough to accomodate the DVI-D connector passing through them.

I was thinking of running a short HDMI to DVI-D cable from my HDMI player to your unit, and then use my existing DB-9 to DB-9 cable from here to the projector. Is that possible?

Cool,

That looks like the same Weller solder station I just picked up. :D

I just got done re-capping a number of Barco 808 input/RGB boards last night. Too much fun.

Essentially true for 8 bit sources. If however we do eventually get 10 and/or 12 bit sources, then not having an HDMI connector will mean a loss of bit depth.

In this solution, no. The reason being he is trying to follow the HDCP rules. HDCP rules are that the signal may be converted to analog within the device, but not external to the device. The rules are such so that you cannot obtain access to an unencrypted analog signal. Essentially, Hollywood wants to punish everyone for the sins of a few. Anyway, there are other external device solutions. Search for "moome".

Yes Dave,

That's the point of these crazy HDCP rules (even, somebody can catch analog video, what can be done with 75 to 165MHz RGB signals :rolleyes: appart from displaying on a PJ ?)

John,

Love the HT.
Just wish I understood what the French Instructions meant. :D
post #38 of 468
Hi John,

My french is a little rusty, to say the least, but I managed to read through your thread about your design.

There you used a SIL907B-PUB. What implications does it have to use the PUB version?

What are you using in your newest design?

I am interested in getting one for my BG808.

Hello Thomas,

Great effort reading french posts !

The "-PUB" version of the IC is feed with generic 'public' HDCP keys to let non-licenced companies evaluating the device without paying the annual fee.

Even I was talking about such suffix, the "-PUB" version of the IC was not used on my converters since I can have normal IC feeded my company dedicated keys in it (my company is HDCP licenced for several years by now).

Many people here are looking for such toy but as said before, the current batch is over. Hope I can do a new batch of these after IFB-DVI Sony Pj next batch in january. I let you all know.

Nice little upgrade John!

Question. Will this input board inrease the PQ considerably over the regular port 5 when just feeding the projector with DVi from a STB DVD-player or an HTPC? I would suspect that the signl path would be alot cleaner?

Btw that HT is just BEAUTIFUL! A+ on that one!
post #41 of 468
Hi John,

I see in the manual it quotes 1080p 50/60 hz, is it the same for all HDTV inputs?

Hi mrking,

Appart from the HDCP stuff that is comming soon for HD-DVD, the BG-DVI module is also interresting because of the increasing of the PQ. In fact, when long and/or poor coaxial cable path is used between STB/DVD player and the projector then, changing this long and/or poor analog path to digital (HDMI or DVI) is increasing the PQ quality even on port 3. That is mainly due to the fact that the RGB ananlog path become very short (even shorter than the STB/DVD player directly connected to Port 3 with 10 cm cables ... :D ).

That is why digital video link in interresting in our HT dedicated rooms : this increase PQ ;)

Sorry baggy, I do not clearly understand your question :o
There is only one HDTV input on the BG-DVI module :confused: 1080P @50 ou @60 Hz is the maximum resolution allowed by the module (165 MHz). For sure, the module sync itself to any (even specific/non-standard resolutions) from 25 to 165MHz !

It wasn't a clear question ( been on nightshift) but you've given the answer I was looking for.
I was trying to ask if it would sync to both 50Hz & 60Hz HDTV signals.

Yes, since these two HDTV modes (European and US) share the same pixelclock and 50Hz European mode have big front and back video porchs :mad: .

I ended up ordering one of these for my 1209.
John was very helpful and my unit arrived safely a few days ago.
I've had a little time to play with it now and it seems to work well.
I'm using a HTPC with a 7800GT video card and connect to it via a Bettercables DVID-9-DL cable.
I don't have a HDCP source so I can't verify that side of it.
I'm pleased with it, for the relatively small cost of 200 Euro it's given me greater flexibility. Hopefully when HDTV or HD DVD's eventually arrive in the UK I'll have no problems with connections.
post #47 of 468
Thank for the small report Baggy,

Don't be affraid about HDCP, some other french people use it today with Pioneer or Denon flagship players HDMI output that have the HDCP enabled and it is working fine.

John
post #48 of 468
Hi John,
I've disconnected from my HTPC and I'm now using it with the HD Leeza and Philips 963SDI combination that I also use.
Currently inputting 1440x960@72Hz.
As far as I can tell it works flawlessly.
post #49 of 468
Hi John,

Are you actually using the I2C logic from the barco to talk to the 907 chip, if so what are you cummunicating.

Thanks
post #50 of 468
John any chance you would consider offering this device in kit form for those that are handy with fabrication?

Thanks

ther no need talk between barco and 907, 907 need one edit to let dvi source know what mode can accept! i will make one cable for my external box, so can use for barco port3, any one have port3 pin definition?

thanks

No WTS, in fact the 907 chip have I²C port just for HDCP and EDID stuff (these lines are linked to DVI or HDMI input connector). Converter part of this device doesn't need any register set to work : it is synchronous to the digital video input. So no need to Barco or Sony PJ to talk with it :cool: .

But, HD15->DB9 cables are available from other sources so you don't really need to make one. The point of this approach is to make the device part of the projector, much like your internal cards. If it is part of the projector, then it is OK with the HDCP cops.

Hello Moome,

Just both replied at the same time on the same question :D

FYR Barco Port 3 port pinout (DB9-S) is :
1- Digital Ground
2- Red ground
3- Red
4- Green
5- Blue
6- Green ground
7- Blue ground
8- HS/CS
9- VS

Yeah, why not ?
But you must be aware that those tiny 0603 SMD components are quite difficult to solder without any binoccular magnifier ...

How about waranty then ?
You should also cut and drill the ABS cabinet by yourself :eek:
BG-DVI device kit would just save some bucks (say E50 or so).

The main issue for me is getting the 907 IC ...

I would never, in a million years, offer a DIY kit with SMD devices ... that's just asking for trouble.

post #57 of 468
Hi,

Well that depends on alot of things, what footprint the smd's have is the biggest concern. Big footprint smd's aren't too bad to work with even for an amatuer I'm sure. Come on Kal, now you're going to scare everyone one off if you keep talking like that.
post #58 of 468
Thread Starter 
I understand where you're coming from Walter - there are lots of people (especially on this forum) that wouldn't have any problems soldering even smaller SMD parts, but if you look at how many problems DIY kit makers put up with because of incorrectly installed (discrete) components already (stuff installed backwards, stuff overheated, broken pins, etc), it would seem foolhardy to offer something that's even more difficult for the 'average' user.

Hi Kal,

I agree, its a risk I wouldn't really want to take as a supplier unless it had a big disclaimer written across the top.
I was just fooling with yea. Hell sometimes I even hate the sh!t.

John,
Are you still planning on creating another batch of boards in January?
Thanks,
