    The difference between 1080i and 1080p is probably more apparent on larger screens than smaller TV. I had Sony HDTV (27HS420) and really could not tell difference between interlace or progressive signal from DVD player or from TV's internal progressive up converter.

    But I am supposing on larger TVs (40+), the difference is more apparent especially with fast action scenes.

    I think for still pictures the information content of 1080i and 1080p is identical irrespective of screen sizes.

    O'Shag: I find LCD (or LCoS) to be stark and unnatural. I prefer DLP, but that technology seems to be dying. People seem enchanted by the "hang it on a wall" thin.

    Maybe the organic LED will prove to be the inheritor of that CRT color smoothness and contrast. The older quite expensive plasmas seemed more film like than LCD to me, but price pressures have reduced the picture quality while keeping the other plasma limitations.

    Cool

    Nice to hear an EE say that picture content suffers when theres movement in
    interlaced material.
    I have been arguing this with sir talky for ever.
    One question, do you think that 1080p OTA will ever happen, or will deinterlacing
    1080i remain the norm?
    Will the very slight advantage of a native progressive signal over one rendered from 1080i
    ever be worth the extra bandwidth?

    It's hard to know, transmitted HDTV will probably stay at 1080i because of radio spectrum bandwidth. Video over fiber or VDSL may improve. Currently there are cost issues. My first progressive DVD was $1,000 now they are $49.95 at WalMart

    It's hard to imagine a better compressor, but if I knew the future I would have bought Microsoft stock in 1983 (10,000 to 1 return).

    Generally equipment improves up to the specification limit over time. NTSC TV in the 1950's did not look as good as SDTV NTSC today.

    I don't think any body denied that high motion scenes does suffer in interlace mode. What started all argument was statement you made that interlace picture is half resolution of progressive mode.

    There might be no reason to broadcast in 1080p if TV (or satellite/cable box) can internally deinterlace 1080i feed and reconstruct it back to 1080p. Especially if source is film base.

    What I actually said was that an interlaced pic could lose up to half of its res if there
    is movement, which is true.
    YOU DONT HAVE ANY SUCH LOSS WITH A PROGRESSIVE FORMAT.
    Deinterlacing 480i was the best thing you could do to it, as is the case with deinterlacing 1080i, because of elimination of interlacing artifacts
