Ok, I have been reading a few spec sheets on HDTV's here and there and this whole 720p to 1080i "upconvert"to me seems pointless.
Why do I say that well, frist of all the TV reads the horizontal scan rate to display the image, being that is the case it would not be a "upconvert" at all, 720x1280 scans at 45kHz and 1080i scans at 33.75kHz. Also, 720p refreshs at 60fps and 1080i 30fps. Plus, 1080i is only the higher resolution on a static image, on a dynamic image 720p has the higher resolution.
Plus why on earth would you care to re-interlace 720p to 1080i? That's one more stage of processing that does not need to be done. Anyone that knows anything about resolution and displaying a image knows re-interlacing is a bad idea. It would be better just to skip that stage and display 1080i.
What's the point of doing this converting?
