Actually, only Blu-Ray has 1080p. HD-DVD can only do 1080i.f300v10 said:First off it will be a very long time (if ever) before any of the major networks broadcast anything in 1080P. There is not enough bandwidth in the ATSC spec to do [email protected] using MPEG2. MPEG4 is not yet a part of the ATSC spec, nor would any HDTV with a built in tuner be able to use a signal broadcast in MPEG4. The only 1080P sources we will have any time soon are HD-DVD and Blu-Ray.
As for any visible difference between 1080i and 1080P, for all films and most scripted TV shows that are shot at 24fps, there is zero difference between properly de-interlaced 1080i and 1080P. Zero. 1080i draws the full 1080 scan lines every 30th of a second. If the source is 24fps then all the data that exists in the signal is being displayed. The only time 1080P would be better is on 60fps material, of which there currently is none other than the PS3 and Xbox 360.
