What do you mean a "normal" scart signal?

DVD players emit some (or all) of the following (in rough order of worst to best quality):
Composite video via single coax connection
Composite video via scart
s-video via s-video socket
RGB via (fully wired) scart
Component video via 3xcoax
Component video progressive scan via 3xcoax

Of course your TV has to accept the signal, and for RGB the scart lead has to be fully wired (some cheapo free-in-the-box leads might not). Also, audio gets carried on the scart signal or by separate connection to TV/amp.

Converting between different signal formats does involve expensive boxes, but you probably just need a scart lead.

Do you mean that your DVD player does not have a scart socket?
Rather, it has individual round "phono" plugs????

However if it does have a scart socket, then it probably already sends RGB signals out of this socket. Some newer DVD drives have 2 scarts - make sure you connect the scart connector on the dvd labelled "tv" or "RGB" to the television. Note also that most tv's now have more than one scart socket, but only one is usually RGB wired - this may be marked by "RGB" or "..." (three big dots. Check the tv manual for clarification.

I would put RGB by scart above an S-Video connection in your countdown chart...

Not even going to get into the s-video vs RGB debate. It's all about choosing what works best for you based on what the box will produce in the first place...

I still cant see much difference between Composite scart or RGB scart.
I have a WS Sony tv, and the main scart input is fully wired (so it's Composite and RGB). The remote allows you to switch from comp to RGB on the same scart. I have a Sony DVD player plugged into this using a fairly expensive fully wired doubled shielded scart cable. The other end plugs into the "tv-RGB" primary scart output on the DVD player.

On a Sony W/S TV you should see the difference!! Are you sure that the DVD is definately set to output RGB, because if not selecting the RGB mode on the TV will still pick up the composite signal.

I've tried S-Vid and RGB from my DVD player and have found that S-Vid is crisper and clearer. Probably varies from manufacturer to manufacturer.

...or even add S-Video by SCART (up to you to decide the position! )

My DVD is def on RGB, and is plugged into the RGB socket on the tv. I use a highish quality (£25) lead to connect them. I still can not see this "significant" improvement between Composite and RGB. And it's not just me. One of my relations has a 100Hz Sony Wega 28" tv with Sky Digital. The digi box is set to RGB and connected to the RGB scart on the tv. Switching between Composite and RGB only provides a "slight" difference. Colours maybe slightly better in rgb, but we both think sharpness is slightly better in Composite mode.

I am a bit new to this stuff too - I've just hooked up a CableTV decoder (Pace) to a small 14" combi TV/Video (Matsui) via a SCART lead.

If I switch the decoder to RGB output then the picture looks sharper but has a green tinge to it.
If I switch it to composite (still with the same RGB lead) then the colours look normal but the picture looks slightly fuzzier.

Have I got a cheapo SCART lead and would a more expensive one give me a sharper picture AND normal colours?
Or is the green tinge part and parcel of RGC scart (I thought the objective was better quality)?

Cheers

There's something wrong if you can't see the difference between composite and RGB signals on your TV...

RGB is clean and sharp, composite suffers from "dot crawl" and "fringing", and the colour can be washed out compared to RGB...

Are you sure your TV etc is set up OK?

Also like to add that on every Sony TV I've seen the composite picture has been absolutely awful -- yes the S-Video/RGB is great but the composite is soooooo bad that I personally would not touch a Sony TV with a ten foot pole quite frankly!!!

They're bad to the point that on white text in composite the letters run into each other. Hideous. Even my old Bush telly isn't that bad!!!

This is just about the only obvious difference RGB makes, but you have to know where to look for it. It more obvious on video game/ computer graphics than on "filmed" pictures. You also can sometimes see differences between colour emphasis, but I'd call this a difference not necessarily an improvement.

Colours maybe slightly better in rgb, but we both think sharpness is slightly better in Composite mode.
Sony's are very good at sharpening pictures. However this is not necessarily giving you more resolution it's just creating an illusion that makes you think the picture is better. I get this effect when watching my Nokia 221t and comparing the modulated output to the RGB. RGB looks obviously more softer than the sharper modulated signal but the modulated signal has noise.

I often compare this effect to that of using Dolby on analogue audio tape. People usually think that the tape without Dolby on sounds better and can only hear the noise during quiet passages.

Overall you pays your money and you takes your choice. If you think one method of watching is better than another, then to you it is and that's how you should watch.

They're bad to the point that on white text in composite the letters run into each other.
Never seen this. Indeed Sony's are one of the best at running very high contrast without any of these effects or distortion occurring. The worst I've seen are Hitachi were when you get overlaid computer graphics they distort the rest of the picture because of the step in brightness on the screen.

Scart has 21 pins/wire S-video has 4 pins or 7 pins if it is rgb.
Scart is better on the whole unless the s-video is 7 pin, then it is the same as scart.

re the Sony rgb/composite debate

Have a 44" sony Rear Proj widescreen
Can switch between composite/RGB via remote control and there is a marked difference - especially via Sky Digital
I have a mid range Scart lead from Richer sounds

There should be a difference between the two, check yur tv/leads

Compare a menu screen with text between RGB and Composite, THEN you should see the difference.
The text is much crisper and more stable on RGB and also much easier on the eyes.

Defo something wrong in your system somewhere if you can't see the difference.

The best place to look for a difference is around the edges of blocks of contrasting colours particularly red on black. Here you should see the infamous "dot crawl", a sort of sparkly moving edge to the colour.

Sony TV's set up well go very good when comparing composite and RGB. In fact the composite can often appear sharper than the RGB picture, since they have very good sharpening circuitry. However they don't get rid of dot crawl on composite pictures.

Seeing I am a new user and cannot post new threads (crazy!.. Surely thats what moderators are for?) I have to reply to this post which I found on a google search.

I recently bought a ex-demo 28" widescreen philips TV with built in DVD player.

Now I have a GameCube, PS2 and a XBox (plus a 2.8ghz PC ) and have RGB scarts for all of them.

I use a 3-way Scart Adaptor to connect all the scarts up at one time and just flick a switch to change to that scart.

Now I use to own a Sanyo 21" TV and use the RGB through them and it worked fine using this device.

I use to know it was RGB [by the quality of cos and...] the fact that if I tried to change the colour setting with the tv control the colour wouldn't change (which is what I'd expect).

But running the scarts through this new TV, in Scart Socket 1 (the one thats suppose to be RGB) I can change the colour setting via the remote, surely this means its not running through an RGB signal doesn't it? Or can you change the colour on some RGB tv?!?!

The quality seems good enough.... but Im sure its not running through RGB?!?!

The logo next to the scart socket on the back has a little box with 3 dots on the side of it (which I would assume means Red, Green and Blue)? But the socket 2 has this also, usually TVs only have one RGB input don't they?

What would you suggest? Philips Customer Service is SH*T to say the least!

Any help will be appreciated, thanks!

Steve,

I also have a Philips TV and use it with RGB input (SCART1) from a DTT set-top box. I've noticed the same as you - the colour can indeed be changed

I'm convinced (99% anyway) that the input is indeed RGB, so maybe this is a feature of Philips TVs?

Not sure this helps, but at least it's not just you!

It must be a philips feature..... weird cos its hardly RGB then is it really?!?! RGB is suppose to sort out the Red, Green and Blue for you.... yet you can change it, interesting

At least Im not the only one.

My Sony 28" widescreen looks nasty with a composite input compared to RGB. I'd hardly say it looks sharper but instead the picture looks much more grainy with composite than RGB. I'll also through in that i find S-Video provides a image on par with RGB when you use good quality S-video cables.

Believe me it is not technically possibe for Composite to be better than RGB, this could only happen if the RGB input on the TV is faulty or badly implemented. Composite could "look" better if the sharpness is turned up but anyone with good eyesight could see this does not compaire with truely sharp RGB. There is no point converting Composite to RGB as the TV does that anyway and you will get no improvement unless you pay good money for a top quality one that is better than the one in your TV. S-Video to RGB is worth it if your TV doesnt support S-Video.

Sony TVs also allow colour change in RGB mode, I think the only thing missing is the sharpness control.

Believe you me when I say this is no bad thing since virtually all TV out there are not set up very well when it comes to contrast brightness and colour. They generaly overdo it on the contrast and colour and end up with a gaudy picture that looks more like a cartoon than real life. Combined with some of the modern filming trends, which also boost colour, some shows look awful.

On the same subject, can someone help, please?
I have a Thomson widescreen tv (3 SCART sockets), with a Pioneer DVD player (DCS303), a vcr and a satellite box connected to it. The TV is connected to the DVD by an S-Video and two audio leads to a SCART (on AV3), and also two audio leads from the tv to the TV line-in on the DVD player.
Now, the problem is that when playing a DVD or whatever, the sound is perfect, but when I watch normal tv, there's nothing coming out of the DVD player (yes, I've changed the input over to 'tv'!) I tried changing the SCART, by moving the two leads that are connected to the S-Video lead from their proper place to the TV-in, and reversing the direction of the flow using a switch on the SCART, but still nothing.
I'm kinda new to this stuff, but is there a compatibility issue here? I see nowhere on either the DVD player or the tv where I can sat to RGB (I don't even know what that is, though).

Please, help a poor soul to enjoy his new system!

Thanks guys!
