Pioneer 43"ers aren't strictly "High Definition"

    I always thought they were, but from my reading up it appears only the 50"ers can lay claim to being "high definition", where High Definition is defined as 720p or above.
    This is evident in their literature which descibes them as high resolution, which to my knowledge doesn't have an industry standard.
    This is because they are 1024x768 (not 1280x768) and will have to compress or cut off a full HD 720p signal. :lesson:
    Am I alone in having been under the impression that they were capable of proper HD?

    and another thing.....

    having just read the PDP TV, pdf brochure which is for the 50 and the 43, it actually says it's perfect for HD material now and in the future, whilst not pointing out that the 43" can't really be given the status of HD.

    There are no plasmas available that will show a true HD signal they all have to down convert.
    I guess though that that depends on how you define HD, in Oz our Ch7 transmits it's so called HD channel in 576p and gets away with it as being a HD transmission. Other channlels in Oz transmit 1080i which all plasmas (AFAIK) have to downconvert.
    I think that there are some LCD panels about to be released that will accept a true HD tx (1890 (?) x 1080i) at their native res...

    1280x720 is HD and it is able to be displayed on several plasma's with only downscaling of vertical resolution.

    Hmm interesting point, 1024x576 is standard Pal definition, However for 16:9 video to have the same vertical and horizontal Res it would need a 1366x768 panel. A 1280x720 panel is matched for 16:9 res.
    Hitahi/Fujitsu market Alis as High resolution at 1024x1024. I guess the Pio 43" is not strictly a Hi Def panel.

    Has anyone got a PDP-43MXE1 or a PDP-434HDE who has also input a 720p signal?
    What does it do with it?
    Does it stretch it “height” ways (to fill another 48 rows of pixels) and then crop it “width” ways to fit it in (there being an abscence of 56 pixels in this direction)?
    Does it work well for you?

    It's that kind of endorsement that lead me to place an order with him already! (a 43MXE1 :D)
    I'll certainly talk to him, I was just wondering if anyone else has done this.

    All you need to think about in terms of resolution is how many dots the signal is made of and how many your plasma has to display it with, The picture itself is not distorted or anything. The 43" Pio keeps the horizontal resolution of the original 720p image (up scaled slightly to fit 768 lines) then the 1280 width of the image is remapped to fit 1024 pixels width of the plasma.

    50" 1366 x 768 has just over a million pixels, 1280 x 768 (Pio 50" res) has 983,040.

    43" Pio and 42" XGA plasmas (1024 x 768) have 786,432 pixels

    42" WVGA panels (852 x 480) have 408,960 pixels.

    Matching that to video signals: 576p has 589,824 pixels and 720p 921,600.

    So the XGA panels still have to "lose" some information through downscaling, but not anywhere near as much in comparison to lower res panels (relatively speaking XGA is closer to a 50" pixel count than a WVGA 42). Any plasma (that has the right inputs) is capable of showing HDTV through down (or up) scaling. But only 50" models have enough pixels to show 720p without losing any info (no plasma can show 1080i or p without downconversion yet).

    I try not to use the phrase high definition myself since it doesn't really have a literal translation!! It doesn't mean 720p, nor does it mean 1080i or 1080p. It is a relative term that means an image that is high in detail (usually assumed to be high in detail in comparison to the current norm). So 720p is high definition compared to 576p and that is the only translation I work with - something that is higher def than current 576p. Only time will tell how the industry goes with the term, as resolution increases to 1080p and upwards the term will either mean whatever the current higher res signals are, or (more likely) we'll end up with something daft like Super High Definition then Super Dooper High Defintion!!!

    hmm sooper duper high defintion! LOL.

    To quote Micro$oft (who must be right ;) )
    "The video most of us are used to seeing on our TVs today, called "standard definition," has at most 480 visible lines of detail, whereas "high definition" video has as many as 1,080. High definition video looks sharper and clearer than regular video, especially on big-screen displays. It actually comes in two different resolutions, called 1080p and 720p.

    Standard Definition Video = 480p and lower resolution
    High Definition Video = 720p and higher resolution"

    But this of course is with reference to their Windows media high definition.

    Anyone seen it on a Pio 43 though? what's your thoughts?

    Problem is "High Defintion TV" comes in 720P and 1080i flavours (at the moment), but just the phrase "High Definition" is not strictly tied to any resolution but had been used to suggest such.

    And Microsoft seem to live on their own little planet so wouldn't worry about what they think - at most 480 lines? What about PAL! 720p and 1080p? What about 1080i!!! LOL!

    Pio 434 receiving even just 720p is enough to make a mans eyes water...

    As an onlooker, it would seem 1280 * 720 would be a reasonable objective at this stage.
    The DLP and LCD systems in projectors and rear pro tv's seem to be up this path.
    Weird that the flat panel LCD and plasma lot want to choose any combination but the "right" one. :thumbsdow They still seem to be influenced too much by PC display numbers.
