1080p??

[Blu-Wave]

Mass-market films - even digital fims - are produced at 24 frames per second. 1080p24 requires no conversion processes, simply a display that can update at 24Hz without flicker (i.e. not a CRT, for example). 1080i (at 50 or 60 fields per second, two fields per frame) not only involves more data than 1080p (at 24 frames per second), but significant conversion artifacts (from film's 24 frames per second). Another minor drawback of interlacing is that, in order to avoid spatio-temporal aliasing between fields it is necessary to significantly reduce the vertical resolution, compromising the quality of the output. :?

1080p24 makes more sense than 1080i for quality and simplicity (from film), for basic data-rate (80% of the data-rate of 1080i60), for compression (both intra and inter frame) and for high definition (avoiding the temporal aliasing filters required by 1080i), provided that the display device can handle the 24Hz frame rate (updating on transitions rather than refreshing and fading like a CRT...
