Nick: Right. This is an excellent document to read if you want to understand more about what effect the signal - http://tech.ebu.ch/webdav/site/tech/shared/tech/tech3348.pdf .

Sharpness is not necessarily a good thing - if your TV has a "sharpness" setting, turn it off or right down.

All digital signals require compression and packetizing - see How digital television works | ukfree.tv - independent free digital TV advice - there always has to be a buffer for this to work efficiently.

Brian, as expected, the analogue picture on flat screen is worse than on crt, freeview is good where available but Sky is somewhere in between, quite blurred. I thought that it would be as good as freeview, so I could see the missing channels clearly. My local retailer says freesat is clearer and believes Sky deliberately blur the picture to encourage people to pay for their hd. Is this true? Many thanks.

Nick: I think you will find that the analogue picture is exactly the same, but you don't have the blurring that a CRT would provide.

You have not said if you are using a SCART or HMDI to connect your Sky box to the TV.

No, Sky do not "deliberately blur" their pictures. In fact, Sky do not have any hand in the encoding of any channels other than their own branded ones.

It is scart, Brian. Yet another mystery it seems. I have a couple of dishes on other sats, foreign. I will manually tune my Sky box to a foreign station and see if that is the same. If you are saying that freesat is likely to be the same as Sky, via scart, then better stick with the limited chaannels on freeview.

Nick: Freesat and Sky use the same transmission on the same satellites.

Almost all Freesat boxes have HDMI connections.

Thanks Brian. I realize they use the same satellite, so that definitely means they have the same picture quality on standard definition?
Is hdmi better than scart, which I thought was meant to be the bees knees?
Kind regards.

Nick: Yes to the picture quality.

HDMI is perfect digital transfer of the decoded information, SCART is analogue and thus imperfect.

Ah, thank you.
Brian, I really must admit I am struggling to feel at home with this flat tv. I just cannot get the colours right, however I play with the picture settings. The white is too stark, like looking at a naked fluorescent tube, there is no hint of any other colour in it. A bright sky is just dazzling white, however low I set the controls, which of course makes everything else wan. I can give a blue hue to things, or a red one, but there is no way to put a bit of yellow into faces, they have to be red, pink, or white!

Nick: I would just ensure that everything is set to "default" on the TV and you have "sharpening" off. Check you are using the RGB setting if you are using a SCART connection.
