    I'm interested in picking up an ATSC tuner and antenna for OTA HDTV programming this coming fall (particularly my favorite show - Lost). However, it seems that ABC only broadcasts in 720p. Unfortunately my HDTV is older and only supports 480p or 1080i, will I be able to view the ABC programming in high def? Thanks.

    You will need a tuner that can upcovert to 1080i.

    What brand and model of TV do you have? Many sets that don't support 720p natively will still scale it internally for display (like Sony).

    Mine is a Panny 47WX53. I bought it about 3 years ago. I'm not sure if it has a function to do what you say.

    Thanks for the replies guys.

    Almost every tuner and most newer TV's will scale native 720p to 1080i. Check before you buy, but this usually is not a problem.

    Oh, so this is a function of the tuner? I was looking at the Samsung SIR-T451 tuner from refurbdepo. Anyone know off hand if this one will do upconversion to 1080i?

    It's actually a function of both/either.

    Here's the manual for the tuner:
    http://downloadcenter.samsung.com/co...F68-00335A.pdf

    On page 12, there is a diagram of the layout of the back panel. #13 is "Resolution select". You would use this to choose the proper HD output.

    Your TV manual is not online, so I don't know if it will also scale the 720p. But it really doesn't matter, the tuner will do it fine.

    Wow, that's great, thanks! Does this typically degrade quality in any serious way?

    The signal is "degraded" because it's not presented in a native format.

    Don't worry about that, it will look stunning.

    Not that I've ever noticed. The difference between 1080i and 720p is there, but it's not monumental. Plus, you really have no choice, most displays are either/or, not both, so you either scale it at the tuner or scale it at the TV.
