Fellow CRT owners, does anyone know what is needed to output DVI from the Motorola DCT 6200 to a Sony 1272? After researching the DVI pin connectors, it seems that the DCT 6200 is DVI-D (digital only) Does that mean I need a converter for RGBHV on the 1272 or is there an adapter that I can use? Any help is greatly appreciated.


Thanks,


John Brooks

John,


I have the same setup. As of right now, I have the Motorola HD receiver (Comcast cable) running through a Brite View Scaler. But, I found a DVI-D to VGA connector on Ebay last week which should be here and day now (supposed to have been friday). I'm hoping today...I'll let you know how it works out.


FYI: DVI-D to VGA connector = $12.95 + Shipping on ebay.

if the connection is DVI-D (which means those four pins on the right in the square configuration aren't there), then the $13 adapter isn't going to work.


What I'm having to go to is a transcoder...

Goofy,


You're wrong about that, the Motorola won't accept the DVi adapter with the four prongs (I got one of those as well from Fry's). That is called a DVI-I. This is the exact connection type used for connecting the HD Receiver to an HD comaptible TV (Like my wife's little 20 inch plasma) just it switches to a VGA. I accidentally bought the other DVI adapter not knowing that there were two different types (analog and Digital). The DVI-D is what is needed, this is the one without the four prongs surrounding the flat blade connection.

Goofygrin is right.You will need a transcoder.A transcoder will transcode the component output of the Moto to RGBHV which can be accepted by the Sony.Do a search for "transcoder" and u'll know more about it.There has been talk of a dvi card for the Sony PJs.This card will accept a DVI input but it is still not in the Market

The reason I went with the adapter is because a couple friends of mine (Who have the exact same setup) are using them...I know all about transcoders and what they do...If you're talking about the Sony not accepting the signal, that's a different story altogether. I was talking about the DVI connection.


I purchased these based on what two friends (we all got our CRT's from the same place) said would work. Now, if it doesn't work, I'll probably break down for a transcoder (I want my HD to be true HD not scaled).


I know one thing, I have the right connection for the back of the Motorala

 

[jabrooks3000]

Thanks for your input guys. The only transcoders I've seen are for YPrPb to RGBHV. I guess that will have to do until a DVI-D RGBHV is available. Can anyone recommend one? JOhn b

Hi John:

Gefen makes one that we have used here with our NEC XG110, and it works very well:
http://www.gefen.com/kvm/product.jsp?prod_id=1209

One thing to watch out for though, I believe that the Gefen piece is calibrated for "computer" DVI, whose red, green and blue digital signals go from 0 (black) to 255 (peak white). Your box's DVI output may be scaled for "video" DVI which has the digital outputs scaled from (as I recall) 16 (black) to something like 247 (peak white). You might ask the folks at Gefen about this as I'm sure it's a problem they've had to solve in the past.

Best,

Jim T

Tuomy is right, there are two different type of DVI ports. One is analog (what they call it) (which has a flat blade with four prongs surrounding it). The other is Digital DVI-D which has the flat blade without the four prongs around it.


The motorola accepts only the DVI-D input configuiration. To get a transcoder it would have to be set up for the DVI-D with the flat blade without the four prongs. As of right now, I haven't found a transcoder that does that yet. So far they all only accept the DVI-I. That's why I thought I'd spend $13 and see what happens since my friends said that it has worked for them.


As I said before, as soon as I get this equipment I'll post the results.



Still no adapters ;(


P.S. I just looked at Tuomy's conversion box post, it says that it does support the DVI-D which is good, but the price isn't $399 . If that's the price I'd have to pay, then I'll stick with my Briteview since it upscales both my HD and DVD. Looks great too.

DVI-D to VGA via a cable simply does not work. They make adapter boxes for this that run in the hundreds of dollars. Now, DVI-I to VGA simply via cable does work.


The other option is to use the component output via component to VGA transcoder.


Also, there is no Briteview scaler that I know of that will scale HDTV. Only passthrough..

 

[Ruffneck19111]

Why bother with the DVI output if you have to transcode it anyway?


Just get a cheap component transcoder and use the component output of the Cable box.


I don't think anyone could tell the difference between DVI and component after it goes through a transcoder anyway.

 

[mrigsby]

I think you misunderstood me..


I'm not upscaling 1080I but I am upscaling 480I


Let me explain...


The Brite View does scale when you output from the Motorola at 480I and then bump it up. The Brite View won't accept 480P or above since that's what it's scaling to. So, by setting the Motorola to 480I, it's not HD at that point, but it is bumped up.


Nor will it accept 1080I through component (I've tried) so through the Brite view at 480I it goes

Also, for future knowledge and so I can bust my friends who said this will work..


Why won't the adapter work? What is it about DVI-D that keeps it from working?


Thanks.

P.S. Sorry for hijacking the thread.

DVI-D does not have RGBS encoded. DVI-I has RGBS on extra pins.


It is like translating alien to English, there is not a conversion and the objects, and things that an alien would talk about would have to reference things on Earth.


You have to decode the DVI, then encode it back to a useable format, hence the transcoding.

The four pins that surround the flat blade on a DVI-I port output an ANALOG signal. You can then use a DVI-I to VGA adapter and a VGA to 5BNC adapter cable to route that ANALOG signal into the ANALOG BNC connectors on your PJ.


The rest of the DVI pins are digital outputs, therefore they need some kind of digital to analog conversion in order to go into the BNC ports on your PJ.
