    Just been wondering how an upscaling DVD player processes it's source in order to output 1080i :confused:

    Does it just scale the individual interlaced fields as they come ?

    Or does it have to deinterlace first...then scale...and then interlace ?

    Cheers, Lee

    The latter. The signal is first deinterlaced, then scaled directly to 1080i (as there's no need to have 2 separate steps).

    Thanks Dale...I thought it must have been but then it begs the question...what is the point of it ? except maybe for ALiS plasma panels.

    Or for any other display which will directly show a 1080i signal (but not 720p or other higher resolution progressive format), such as many of the CRT-based RPTVs out there. I'm not personally fond of having to re-interlace the signal, but it's necessary in some cases.
