Hi Guys,

Im new here and decided to post my question. Have done some research predomently over this fourm about hooking sky tv up through component cables. I have a new 42" Panansonic plasma.

Following advise on here, i purchased the Jaycar SCART to Component cable. However, when i pluged sky in using this cable, and changed the Sky Settings in the menu, the picture quality was distictly alot worse and less sharp than when running through the orginal SCART to Composite cable?

Does anyone have any advice on why this would be, or any remedies? Surely the picture quality sould improve running component cables.

Also, while im posting, i have purchased a new Yamaha DVD player at the same time as the TV. The quaility is excellent, but i can only get it to run in 576p. Was wondering how i get it to run DVDs in a higher resolution. Have i connected to the TV with Component cables. Would changing it to a HDMI help?

Any info appreaciated! Cheers!

PAL DVD's are all 720x576 so you will only get 576P output by default. To get any higher you need a DVD player capable of upscaling. Many new DVD players are so I would assume if it's capable it would make mention of this somewhere. Changing it to HDMI shouldn't many any difference.

You would need an upscaling DVD player to be able to generate an image > 576p. But not sure in the PAL world but I suspect it's the same as NTSC. An upscaling DVD player can usually only upscale over DVI or HDMI and not over component. For some mistaken reason, the content owners felt that there was a chance of content piracy if upscaling occurred over component whereas over DVI or HDMI they could enforce HDCP.

Of course this is crazy really considering you can upscale with a PC to any resolution you want and/or just copy the DVD and upscale when playing the content

Logic has never being at the forefront of the content industrys minds.

Case in point, I got some dvds from fatso, I usually play on the PC, but decided to watch one of them on the TV via a DVD player.

Now, how positive to the copyright holders do you think I feel after having to watch that damn "you wouldn't steel a car" anti piracy video - all 1:30ish of it, before I could even get to the menu. Yes, it make me hate them even more, and the fact that it makes it more usable for me to run dvd-shrink across it choosing main feature only is just the icing on it.

Now, what the HELL was the guy that decided to make that non-skippable thinking. Do they really think it will do anything other then annoy people? The normal copyright warning is bad enough, but that.... geez...

This is quite the opposite to what I have experienced with all the Sky decoders that I have assisted to Component. This includes both the Panny PA60 and PV60, both good plasma panels as plasmas go. Are you not confusing chroma crosstalk for extra image sharpness?

Have you checked the setup parameters for the component input, as I remember it the Pannyies store the settings of each AV input seperately, however all the RF channels are stored as a common setting, unlike philips desplays that store each AV input and RF tuner channel independantly.

Thanks guys for all the info.

What is chroma crosstalk? To me the image is blatantly alot less sharp and looks worse than when compared to composite?

Any setting you suggest i can play with to try and fix this. Yes all the AV setting are seperated on this Panasonic

Thanks heaps again!

Chroma crosstalk produces the commonly described dot crawl. This means that around the edge of mainly highly coloured items there is a dot crawling type effect.

Normally I have found that its best to turn off all DNR (digital noise reduction) and mpeg noise reduction processes. Ensure the sharpness is set to midway.

What model STB do you have?

The model is a DS230

That seems to be what im getting, this image is very fuzzy especially around edges. Alot more so than when it was connected by composite.

Ive played with the setting and find it looked better, but not great with the MPEG noise reduction set to strong?

Sounds odd, the DS230 that we have looks very clean and sharp compared to composite on our PJ. I have also found all the DS230 that I have dealt with to have no such issues, and there are quite a few.

Either there is something wrong with the input on your TV or the output on this particular DS-230, I would find it hard to imagine a simple 1.5meter cable could have a major issue.

I normaly find its best to turn the mpeg filter off, not on. Infact switch off al digital processing that you can.

Quite possible that its just showing the low chroma resolution on mpeg at skys low resolutions for what it is, whereas the composite has some enhancement going on since its even worse.

thanks for all the help guys, guessing it might pay to get the Sky Tech out here to see if theres a prob with the box itself. Its just such a fuzzy image, especially around all the bright edges.

Cheers!

Does not sound right, Ive been involved with literally dozens of Sky boxs where I have upgraded the interface to Component, and the image improves period.

Sky has low bit rates on many channels, however the sports and movie channels are operated at good bit rates such that any compromises that may benifit composite should not show on those channels. Prime seems to also have good bit rates. Will be interesting when Sky finally move to Hpol and drop their own streams of TV1/2/3/C4/MaoriTV and point everyone at the FreeView streams that typically run DVD rates.

Fuzzy around the bright edges sounds like either your watch the low bit rate channels or some excessive processing is on in the display.

Ive turned off all digital processing and basing all my oberservations on the Sky Sports channels, which i watch the most.

Just things i notice is that edges are not sharp or defined, and say with sport, the crowd in the background looks pixelated and the image in focus is fuzzy around the edges.

It does seem very strange that its doing this given the info you have provided me, and your experiences.

What do the STB menus look like. Compare the menus on composite and component. Assuming they look fine then any issue there on out has todo with the mpeg coding and source material that Sky uses. By and large I find most live/local sport on Sky to be quite clean and without lots of edge/motion related pixeling. Movie channels also look good, but then again progressive sources are much easier to code. Definitely dont look at ESPN or any sports thats been pulled in from overseas.

Just had a quick look, all the sports channels look pretty bad at the mo, but all are pulling in overseas sources, the tennis (once I got past the on field females) looks very pixelated around the edges, but this is due to the thin pipe from Europe. The pixelation is even noticable on my 29" S-vid fed Sony CRT.

If you go to 21 Movies2 you will see what reasonable coding should look like. Looking at it (being julia) I would suggest its approaching DVD quality.

[update] UltraViolet has also just started on 20, again this largely CGI based film is as sharp as any DVD, with no signs of edge pixeling or obvious mpeg artifacts.

I know it may seem strange for me to suggest looking at the cleanness of the menus. But you are trying to demonstrate the improvement of the internconnect between the STB and your display, which should mean an improvement in actual picture quality. However are more capable interconnect may showup poorly coded images worse not better, this does not however make that interface worse, just more informative.

Any idea what cable you got? Is it on there website. I'm struggling to find SCART to Component cable anywhere locally (im in Napier)!

Try this

You can also use a PA3667 adaptor and cables but doesnt do audio. DSE have the same adaptor (DSE P6699)
