totally random but has HD been fully done yet, I remember ages ago progressive scanning (better movement) could only be done on 720 lines, can they do it on 1080 now?

 

[cheesy feet]

Yes, i believe HD is also 1080 progressive scan and active interlaced now, but i'm not convinced that the likes of sky are making use of it yet. I think you will find that sky HD broadcasts will be in 720ps. 1080ps will probably be used more by Blue-Ray and HD DVD.

It's a funny area actually, a lot of the TV's that people buy are badged as "HD-READY", but they can only do the 720 HD, although they can probably interpret the 1080 ones. Makes me wonder if some people will be dissapointed in the future when they find that they cannot make the most of their Blu-Ray players etc.

I have been holding on for a bit to my old 36" tube. Old, but still a relatively good pic. I will wait until more HD tv at a reasonable price is ready (freeview won't look into it as much until after the digital roll-out), although BT make their additional services via broadband on their STB delivered in MPEG-4, which is an improvement on the normal (non-HD) MPEG-2 quality anyway.. Until recently plasma and LCD just haven't really given the picture quality people hoped for, but i've seen some pretty good ones recently, and at better prices.

I only know a bit about this, but section 4 in this link explains some of it quite well. I pick up some of it through my work (related to video on demand) and my dad who designed concert screens used at eventsplaces like the brits.

With interlaced formats, any horizontal motion in the original source between frames results in blurring. Similarly vertical motion results in flicker (the "venetian blind" effect). These defects are eliminated in progressive scanned systems. For example in 1080I, a moving football quarterback’s image is dissected into 1080 lines ONLY HALF OF WHICH are painted each time the screen is scanned. The portions of the quarterback’s body represented by the other half of the lines remain back where he was before he began to move. By contrast, progressive scanning re-paints the quarterback’s entire image EACH time the screen is scanned. As a result, progressive formats do a better job of rendering moving pictures.

so yeah, progressive scanning is 'better', and 1080 p is now available


awesome


thanks
