SCART RGB output

hey you guys beat me to it, this is my new specialist subject, everything to do with RGB convertors.

You can get Scart RGB convertors to a number of formats, BNC, phono etc.

Given my new knowledge of all things RGB, I set my Mums cable box to output to RGB and widescreen, it was 4:3 composite before, she was using zoom to fill the screen!! Even she said how much better the picture was compared to composite!!

Justin, be careful not to confuse the terms "converter" and "format" which refer to TV or scan system conversions, not the simple case of supplying a lead that connects an RGB SCART socket to a row of RGB BNC connectors.

I worked extensively in the sound and video business as an electronics engineer and even I need to dig deep into DVD and TV manuals to get friends and family systems set up to take full advantage of the available output options.

I was hoping I could just use a scart to 3xRCA RGB cable. I don't really want to buy a converter box, since it costs double what the DVD player did! I only got this player (Yamada DVX-6100) for playing DivX and XviD files, since I have an Arcam for playing "proper" DVDs.

Rob, I read up via the link I gave you above. Your projector has (in order of quality) composite, S Video and component(YUV).

Although your DVD has a SCART connector, it doesn't say whether it is fully capable and supports the RGB pins. In any case, the RGB to YUV (component) convertor will cost you more than the player.

To be honest, I doubt the quality of DiVX signal will be embarrassed by wiring it via the composite sockets, and the S Video connection will certainly beat the bext DiVX signal quality. Don't bother with RGB, you can't do it in the way you are thinking as the DVD and projector aren't compatible.

Colin,

I'm not proffessing to be an expert, so as normal i recommend everyones DYOR!!

I'm just learning about scan rates etc since I'm in the process of building a PC for dvd playing, recording, pausing live tv and as a music server. To start with I'll be outputting to a 100hz CRT until I can afford an LCD.

I didn't want to settle for a svideo signal from the video card so have researched using the hd15 (monitor socket) direct to the tv with a suitable scart to hd15 lead.

Now I know computer monitors and tvs work at different scan rates, s you can either get a lead with a hardware dscaler etc built in, or use software such as Powershift to output through the monitor socket a suitable signal as the correct scan rate for a tv. I need to make a lead up which connects the hd15 to a scart, wired correctly for RGB, hsync etc. Will certainly test my soldering skills smashfreakB.gif

Aha! I've found the answer finally, and the good news is I don't need any fancy converter boxes laugh.gif

How easy can DVD Players with Scart-RGB be connected?

Amazingly well! US-Readers may not be interested by the importance of this question (as there are no Players with Scart), but a lot of european players do have RGB-Outputs hidden in the Scart-sockets. "A" and "B"-inputs accept the so-called " 15k RGB" signal both with 50 and 60Hz picture frequency (or: PAL or NTSC) All what is needed: an adapter from Scart from the DVD Player to four RCA plugs. Three of it carry the RGB signals (from Scart 15,11,7), the fourth cable strangely needs the composite color picture signal of the Scart pin 19, which is connected to the socket marked with Sync/HD on the 10HT. Then set the respective input in the menu to "Computer" or " DTV-GRB", both adjustments work. There are options for adjustment the horizontal size, image position in addition, all display formats can be used (only in15K mode, not with higher scan frequencies!). Sony built into the 10HT a thing called "sync stripper", what extracts the sync impulses from the FBAS mixture. This is, how a true home cinema projector should be, because now the highest signal quality can be transported to the VW10 by each reasonable DVD Player. Advantage of RGB: the whole color bandwidth is used. Since the VW10 processes s-video signals very well, the difference to RGB is not too large, however with special test patterns you will see it (as with YPrPb). Fine color details and color edges are better defined, so it is well worth the effort.

Rob, the RGB output isn't "hidden" in the SCART, it is a feature of it but not always supported by the DVD player itself. The suggestion above is a way to strip the H&V sync pulses from the composite output then mixing that with the raw RGB signal. Personally I don't think this method will work because your projector has a component not RGB input.

Colin does that mean that he can only input the R, G and B from the scart and not the H/V sync?

Also what is the arcam player outputting? and is it near the Yamada player...the reason i ask is if it had a RGB loopthrough then would it be possible to input the RGB into the Arcam and then say use the Arcams Componant out to the projector? i'm i chatting dung.gif because we have to assume that the Arcam would output/convert the RGB in to componant. Which come to think of it now seems unlikely! ices_blah.gif

Does the Yamada have an S-video out? even via scart?

..also what home cinema amp are you running if any?

The player definitely ouputs RGB through the SCART; it says so in the manual.

It does accept RGB as well. Here's another bit from the same FAQ:

"The input variety of this projector is a dream also for seen-it-all professionals: Video and S-video are standard, but two further ports equipped with 5 RCA-connectors are the stuff, high end video dreams are made of. They are called simply "A" and "B" and can be configured for RGB or YPrPb. These ports work with everything. Really everything, except three phase current :-) Whether a component output of a DVD Players, a HDTV Settop box or RGB from a PC: no problem, if the suitable adapter is within reach. Especially good for us Europeans: even RGB from a SCART (ever seen one in US?) socket works immediately".

It's got an S-video out socket, but I have no S-video cable running up to the projector. At the moment the Yamada is connected via composite video to the amp (Yamaha DSP-A1) which then goes to the proj. The picture isn't too bad but if there's a better way to do it I'd rather use it.

Sorry, I didn't read the projector manual properly. For the best image, connect all five of the RGB sources (R,G,B, H&V) from the DVD to the projector. Take the audio from the SCART separately to your amp. However, I would think the DVD players RGB amp will be insufficient to drive a long cable up to the projector, so how about putting the RGB in from your Arcam and Yamada into a SCART switching box (that supports all pins) and use a Keene RGB syncblaster lead from the SCART box up to the projector? The Keene lead has an amp built in so it can power the length of cable.

You'll need to process the audio separately (again the £20 box I got from B Tech does the job).

Bear in mind the source material you are playing on the Yamada isn't really going to be limited by a composite signal (Divx) but it's probably worth wiring your system up properly to start with.

You can buy proper RGB cable by the metre from Maplin and make up your own lead if you prefer.
