SkyHD likely to output both 720p and 1080i?

    Or is it likely that I'll be able to say 'no thanks, 1080i only' - and it'll convert internally?

    Just that it seems my TV doesn't accept 720p (philips 30pf9975), and its only a year - and £2k - old, so no chance of a new one just yet :(

    Sky's HD website simply states that
    The use of "either" "or" would suggest that the Sky+HD box will convert between the two standards internally.

    The Sky HD box supports both 720/50p and 1080/50i - and HD broadcasters will be able to chose which standards they broadcast in. Sky couldn't really hope to proscribe a standard for all broadcasters to chose I guess.

    I would hope that Sky's receivers (like many sold in the US) will internally cross-convert between the two formats, allowing you to operate in one of three modes? :

    1. Output 720/50p in 720/50p and 1080/50i in 1080/50i
    2. Output permanently in 720/50p (de-interlacing and scaling 1080/50i to 720/50p)
    3. Output permanently in 1080/50i (interlacing and scaling 720/50p to 1080/50i)

    If you have a 720/50p native display it will be interesting to compare picture quality between 1. and 2. - to see if your Sky box or your display have the better de-interlacer and scaler when dealing with 1080/50i broadcasts... (Assuming Sky allow for a permanent output standard option)

    If the Sky box does a good job it might be worth running with a fixed output - especially if your display pops up annoying on-screen graphics or takes a while to lock-up on an input format change?

    I'll keep my fingers crossed then. Although its still crazy to have a 720p panel and have to feed it 1080i, its supposed to do a good job of downscaling (after the sky box might have upscaled it...)



    Although if it doesn't work, it means another TV and that'll have HDMI, so my PS3 is sorted :). And they are much cheaper than they used to be, so I could afford a 40".....(feels credit card slowly warming up)
