Progressive Scan - how good is it?

JAMFish72 · 12-06-2009, 11:38 PM

I'm about to buy this TV tomorrow:

Buy Alba 16in HD Ready Digital LCD TV. at Argos.co.uk - Your Online Shop for .

And I would like to use the component video connectors for the progressive scan feature of my DVD player.

What I'd like to know is, how well does the progressive part work in reducing flicker, and what problems would it have on, say, video sources like BBC comedies from the 80s and so forth?

Also, I don't have the component video leads, but they seem to be the same type that connect to audio/composite connectors, whatever they're called. I should be able to use those, right? And I don't care if they're not "gold-plated" and all that fluff, I doubt it really matters.

Sorry if this is in the wrong place, but I've only got a few hours to get responses.

On a 16inch screen I probably wouldnt even notice if progressive scan was on. It does reduce flicker in screens ive seen 32inch and above. You cant use composite cables as component, you need a dedicated pair of cables. Dont need to be expensive, £10 should do it for 1mtr

So progressive scan really isn't worth it, but just stick to RGB SCART? Also, how are the cables different to phono leads, as PS cables seem to be?

If you go with RGB scart you wont get progressive scan. Its not for me to say whether its worth it or not, try and find out if you notice any difference. Composite leads dont have the band width to carry a progressive scan signal, you'll need component for that. The cables that come with the PS are composite leads which produce a poor picture.

Um, I meant PS as in Progressive Scan, not PlayStation.

Oh sorry

I hope my answer was enough for you?

If the LCD panel is progressive, then the TV will turn every signal regardless of type to progressive scan and the resolution of the panel. Even RGB Scart (576i - 768p with that TV).

If the signal is already PS, then it skips the deinterlacing bit and just upscales/downscales to the right resolution.

Progressive scan on a 16" screen!
Don't make me laugh

With helpful answers like that you should make lots of friends on this forum

Lcds don't suffer from flicker in the traditional sense say a crt would.

This is true, but I have seen definite improvements in the PQ switching PS on in the DVD player (connected by component) - a more stable, less noisy image.

However, long time since I have done that as everything is HDMI now...

Component is better than scart so it would definitely produce a better image.

And as with all progressive displays, it is better to feed them a progressive signal as opposed to letting the display handle it as many lower end displays have poor de-interlacing.

I wasn't talking about Scart vs Component though.

I was talking about PS vs non-PS, both using Component.

Ah right again as you say there will be an improvement in picture quality as progressive displays deal with progressive signals best unless they have a very good de-interlacer.

Just to put my pedant's hat on for a moment, component is a signal type, scart is a connection type and can carry one or more of the following signals: RGB, composite, s-video, and component (although component over Scart connection is rare), as well as sound.

Component can be both progressive scan and interlaced, whereas RGB is only interlaced. On an interlaced basis on SD material, RGB is better than component in "theory", but in practice there's nothing between them, but component can support higher resolutions than the 576i (?) that is supported on RGB.

On a 16" screen however, you won't see any difference between component over 3 cables and RGB over a scart connection.

Component is a cable type too.

Mr Incredible · 13-06-2009, 5:12 PM

Progressive cables? Never heard of them.

Or do you entwine them to get interlaced component?

No you're absolutely right, I was just assuming if we were using component we would be using say a progressive dvd upsclaer or something, as opposed to using component as a composite cable i.e red and white for audio and yellow for video.

Most people would assume scart is better than compsoite, but again using your example above if we use a normal scart and a composite cable there will be no difference as the normal scart with less pins is essentialy a composite cable.

If you use an rgb scart cable with a dvd palyer and tv that is rgb scart capable then there would be a difference.

A component cable consists 6 connectors of which you could use red, green and blue for video and red and white for audio.

Or use red and white for audio and yellow for video i.e compsoite.

A component cable has a red, green, blue, red, white and yellow connector.

When using the red green and blue for video component is capable of carrying 1080p signals and interlaced signals.

You're confusing connections and signal types again! You cannot and should not compare the two; it's confusing for those who struggle with getting the best out of their equipment!

Your sarcasm radar detector must be on the blink!

Since when did a "component cable" have 5 cables? You're talking about a multi-cable scart break-out lead aren't you?

I think you're on a wind up.

I'm not confusing anything, scart is capable of carrying a composite signal or an rgb signal.

You can get a scart cable, an rgb scart cable, a composite cable and a component cable.

And yes composite and component are also types of signal.

Yeah you're defintely on a wind up.

I'm sorry, but you've lost me as well.

Any component video cable I've used consists of three cable lengths terminated at each end with an appropriate plug for the system (6 x bnc-phono)

Quite so

Red, Green and Blue.

Having failed to antagonise BaldyBouncer into a fight by accusing him of resetting the screens himself or taking unrepresentative photos, in the Currys thread, he is now after other prey

Unfortunately for Jay, Bob knows what he is talking about

I think he might be talking about the xbox lead which is component, composite + stereo.

Because you wouldn't let people sell you a SCART Lead with the SCART sockets cut off and 5 sets of RCA plugs blutaked on, in the belief that it's a Component lead.

Nor would you believe that the colour of the SCARTS, that were cut off, (ie pseudo gold plated or not) would define the quality of the cable used
