Scart to Component

dmca

Need a spot of advise with cable connections. Just recently got a projector (Panasonic PT-AX100E). I have managed to connect up the DVD player to it via s-video and the the pic quality is great as far as I am concerned. But I would like to connect up the chorus set-top box but the projector doesn't have scart socket (http://www.audioholics.com/productreviews/avhardware/images/PT-AX100U-rear.jpg). I thought that a simple scart to component cable would do the trick but the pj reports no signal. I have tried this cable with a plasma and two dvd players (both output RGB) and the cable doesn't work with the plasma either (I did obvious changing of the signal input on the pj and the plasma). I even returned the cable claiming it was faulty and the second one is the same. So to summarise how do I connect a scart devise to a pj with only component,hdmi, s-video and monitor rgb sockets? Any help/suggestions
thanks a million

Make sure the cable is scart to component, since that cable sounds like it's more component to scart. It's down to the pins. I had a similar problem before. It was just the wrong cable.

don't think the Chorus boix has RGB output

so the best solution to maintain the output quality would be Scart to S-Video

The conventional RGB scart to Compoment video route uses a device like this : http://www.hifistore.co.uk/product.php?qsProd=QCV. These are commonly used to route RGB scart from Sky boxes to plasma/LCD screens.

You might consider getting an upscaling dvd player which would output 1280x720 to match the projector and use HDMI - you'd see a substantial improvement over S-video, which is near the bottom of the video quality food chain.


To get an idea of how much your image could be improved, try connecting a PC with the resolution set to 1280x720 and play a dvd................

Heres a couple of links for info ,

The picture you posted shows inputs labeled as Y Pb and Pr , this is not quite the same as RGB , its a Luminence chrominance type signal as a opposed to the colour difference signal of RGB.
Everything eventually ends up as RGB in the TV or projector but conversion from Y Pb Pr to RGB and vice versa requires circuitry , a cable on its own will not do the job.

You need to check the specs on the Projector and see if those inputs can accept RGB , some are very specific about this Not being the case.
If it can accept RGB then this usually has to be toggled from Y Pb Pr to RGB manually.

Most DVD players have a component out these days , if yours does then your best bet is to connect the chorus box via the s video or the single yellow composite connector , and connect the DVD using the component.

Thanks everyone, hope you all had a great Xmas

Paulw: I checked with the cable maker website http://www.vivanco.com and yes product sics1302 is one directional, comp to scart, I need scart to component, bummer! The annoying thing is the product clearly has 3xCinch <-> Scart on the front so I assumed that meant bidirectional!!

formatman : I also checked the Chorus supplied Sagem Set-top box manual and it appears to output RGB, http://www.sagem.com/support/site/livret/LU_UK_ITD64_62_61_60_58_V2.pdf ,Page 11. so there one positive.

The Ritz: I have just bought an upscaling DVD/Surround Sound system, http://www.pioneer.co.uk/uk/products/42/100/42/DCS-360/index.html ,it doesn't seem to accept scart input or process any kind of input other than it's own DVD processing, Boooo.

mathias: I read the spec for the projector and I can't tell whether it is true RGB or Y,Pb,Cb! Any chance you could have a look? http://techdocs.panasonic.co.uk/docs/1z4593e2a7z3z24345z656ez706466z21z3c32c40b6ce4986cb26bc2a464ed6cb4e082288f/tsn2/data/EU/PTAX100E/OI/769736/BPT-AX100E.pdf, page 47

Thanks again, it looks like I need to try a few more cables before I get projector TV!

like you say the tv scart on the stb says it supports rgb connection (aux doesnt). I know my projector supports both rgb and yuv, i'd be surprised if most don't. Have you tried the projector with a direct rgb component cable to a dvd player with component out to make sure the projector is working okay

eolhc, thanks for the idea, unfortunately I have three dvd plapyers of various vintage but none have RGB component out! I can only assume the projector is fine until I get the new cables.

I was thinking of trying this baby.. http://www.maplin.co.uk/Module.aspx?ModuleNo=98004&&source=14&doy=29m12 multi input upscaler which outputs on 15pin D-sub VGA which the projector does have. Does anyone have know any recommended upscalers or advise on them? Will this really give near HD tv from simple std def Chorus? Would this not make the likes of SKY HD a bit of a lame duck.

Cheers

thats pretty pricey,
you could always try make your own scart to component cable, thats probably what I'd do.
Looking at the scart pinout a component to scart cable it's a simple connection, so the cable you got should work, you could test the cable you bought with a multimeter and see that the right pins at the scart end are connected to the right pins on the rca end

Ok, first off, read this which will explain to you why you cannot use RGB and Component in the same slots without some sort of conversion.
The RGB Scart to 4 RCA that you have is for Sync on Green (or blue or red) which some converters (eg some home cinema Recievers) can use. This sync is built into the VGA connection which you link to in Maplin.

From what I can see from the manual for your projector you have inputs for HDMI, COMPONENT (Y/Pb/Pr) and PC (VGA) input.

You can plug a Component based DVD player directly in, likewise with a HDMI one, for the chorus box, either the maplin converter should convert to VGA, or this will convert RGB to Component.

I had the same issue many moons ago. You need a specialised piece on kit.

Follow that link. They are a Scottish based company that will supply you with a superb RGB Scart to Component converter.

I have one of these that I no longer use for my Panny PT AE 100E.

If you dont want to pay £145.00 plus delivery I am sure we could come to a suitable agreement.

I have given up on the idea of getting RGB out of the Chorus box and have changed the settings to output S-video on the Aux scart output which I use a scart to s-video adapter on. This gives me an input to the s-video connector on the pj. S-video is fine considering that SD broadcasts over Chorus signals are not the greatest anyway.
Thanks everyone who contributed, I have learnt a massive amount from this thread.
Cheers.
