SKY thru scart to HD-TV...is it still interlaced?

[snadge]

I was told some time ago that my TV 32" HDready (768x1366) will upscale / downscale and de-interlace ANY input to 768p (as thats the panels res..)

get this: I have SKY (not HD or + ) and its connected to my HDTV via scart - now i can notice interlaced lines on some objects - especially the deaf women who stands in corner waving her hands about...

am i right in guessing that SKY is 576i and my TV is upscaling to 768 but interlacing THAT signal aswell - so if a signal is interlaced it keeps it that way and only re-scales it to panels resolution?

hence if i put my HDMI DVD player on and choose 1080i the image on screen will be 768i , but, if i choose 720p the image on screen will be 768p

Yes, any source will be up/down scaled to the TV's native resolution (actually, to something about 5 percent larger and only the inner 768x1366 is displayed -- to simulate overscan). Any interlaced source should be deinterlaced before scaling. I don't know how much artifacting your are seeing, but deinterlacing is never perfect. Some artifacts leak through.

so what Iam actually seeing is poor de-interlacing and artifacts seeping through? i heard a feature called polarization is used to deinterlace..?

to be honest it was on constantly - im almost sure it was a constantly interlaced signal - but perhaps your right..

does it matter how the input is sourced? SCART , ARIEL , HDMI

I have SKY wired up with SCART and ARIEL and can use both, scart seem a little better with color but thats about it

....i need a new TV AND SKYHD+ ....thats what i need

my TV is showing vertical shades in dark dull scenes when the camera pans left or right you can see em , as if some vertical lamps/tubes are lowering in brightness or some groups of pixels are - this is only noticeable during dark+dull scenes when camera pans - in still bright scenes its not...any ideas?

also - what does SKY broadcast in? (standard def.) is it 576i or 576p ...?

I've only heard of polarization used for stereo 3d displays. This is where you wear special polarized 3d glasses that show one field to one eye, the other field to the other eye.

to be honest it was on constantly - im almost sure it was a constantly interlaced signal

That sounds a lot worse than the occasional deinterlace artifacting.

I can't really answer the rest of your questions because I don't live in the UK and don't have direct experience with Sky or SCART. Hopefully someone else will step in...

Scart only handles SD interlaced - but the quality of the signal (RGB Scart, sometimes called "Full Scart") is up there on a par with a component connection.
Scart also comes with a cut down version that is just composite or Svideo (I forget which - maybe both), reducing quality.
Often, to cut costs, a TV with 2 Scart inputs will have "1 Scart and 1 full Scart". Make sure you're plugged into the Full Scart/RGB connection.
It looks like the de-interlacing/rescaling is done totally by your TV, and it's in this circuitry that manufacturers often cut corners to meet a price point, giving less than optimal quality.

how do i know which is full scart - i do believe when using HDMI DVD player in 1 scart socket SKY wouldnt come on when pressing the SKY button on remote but on the other socket it would... theres no diff in pic quality in either port... also PAL is set on my SKY box , when RGB is selected some fuzzines (noise) appears on the yellow arrows on the SKY menu

am i best getting a "SCART - to - Yellow/Red/White" cable (is that component?) and pluggin it into that and choosing RGB...? i dunno - ive been told on AV-Forums that its possibly the cheap scart cable picking up interference and i should get a good quality shielded one?

the TV was a cheapo when they started selling in UK 2 years ago it was £399 , BUSH 32" from Argos - says it all really - we got it replaced 6 months in and the 2nd one did appear to be less quality (less sharp) - and is different set but same crappy brand -generic) - NOW its go vertical shades (thick lines) on the screen only noticable in dull dark scenes when panning left or right - new TV really and SKY-HD+.... thats WHAT i need to do lol

The Yellow/Red/White cable is composite video, right audio, and left audio, in that order. That is the lowest of the three possible qualities you get with SCART: composite, s-video, RGB, with RGB being the best. The adapter of which you speak would not convert the RGB to composite. It simply connects the composite pin of the SCART connector to the yellow RCA connector. If you set the Sky box to output RGB there will probably be no signal on the composite pin.

i dunno - ive been told on AV-Forums that its possibly the cheap scart cable picking up interference and i should get a good quality shielded one?

That would not help with the deinterlacing problem. It might clean up the banding you see in dark areas -- but that is more likely a malfunction of the TV.

I TOTALLY AGREE - I think the TV is just crap - poor upscaling processor and now the pixels are dulling (the lines i explained) - ive had for 18 months and it HAS been on an avg of 8-12 hours EVERY DAY

need a new one - my dad just bought a samsung HD TV 32" with 10,000:1 (30,000:1 dynamic) contrast ratio and DNie for a measly £309 - that with his FreesatHD is supposed to be a 'marvel' (his first large screen / HD experience - cant wait to see for myself but he lives 350 miles away )

HD through scrart - what a WASTE!

[snadge]

thats true - i dont have HD thru scart like?? - just normal SKY through a CHEAP SCART and CHEAP (bush) 32" HD-TV - infact im certain the quality of it through the standard ariel has less noise on the picture

]HD through scrart - what a WASTE!

The OP never had HD - it was Standard Definition SkyTV.
