I have a bunch of questions about viewing HDTV broadcasts on a computer.
1) Assuming I use a typical PC DTV card, for example the MIT MyHD card, I was wondering if a computer display is capable of displaying a 1080i (1920 X 1080) signal without scaling it and losing image quality? I'm also assuming that the maximum resolution that my monitor can run at is 1600 X 1200. If the image is scaled, how is the image quality affected?
2) Assuming my monitor is set at 60Hz, and mpeg2 video is 30 frames per second, does this mean that the monitor shows each frame exactly twice?
To complicate the question, now lets say my refresh rate is set at 85hz. Tell me if I'm wrong or not, but I'm assuming that each frame will appear on the monitor appear 2.83 (approx 85 / 30) times. A computer cant show certain frame only .83 times. So what actually happens?
3) Does the "raw" mpeg2 data being broadcast have any information about how it will be displayed? If there was such a thing as lets say a HDTV 720i broadcast standard, would it take any less bandwidth than a 720p broadcast?
Thanks,
