ik denk dat ik het al gevonden heb,maar verbeter me als ik het toch fout heb gevonden.
1080i film-based content can become true 1080p
The following examples refer to content that is encoded in progressive-scan form during recording or transmission—what would be considered "native" progressive signals. However, where 24 fps film-based material is concerned, a 1080i encoded/transmitted stream can become a true "1080p" signal during playback by deinterlacing to re-combine the split field pairs into progressive film-scanned frames. Regarding 24 fps film-source material presented in conventional 1080i60 form, the deinterlacing process that achieves this goal is usually referred to as "3:2 pulldown reversal" [also known as "inverse telecine"]. The importance of this is that, where film-based content is concerned, all 1080-interlaced signals are potentially 1080p signals given the proper deinterlacing. As long as no additional image-degradation steps were applied during signal mastering (such as excessive vertical-pass filtering), the image from a properly deinterlaced film-source 1080i signal and a native-encoded 1080p signal will look approximately the same. It should be noted that Blu-ray Disc and HD DVD sources are 1080p with no vertical filtering, therefore, 1080i output from players can be perfectly reconstructed to 1080p with 3:2 pulldown reversal.
As more and more processors and displays come to market able to apply 3:2 pulldown reversal to film-based 1080i60 signals, the amount of available "1080p" content for viewing expands (encompassing film-based 1080i60 feeds from broadcast HD, cable, and satellite).

volgens mij wordt de film dmv de xbox360 gecodeerd tot 1080p film.
wat ik wel vreemd blijf vinden is dat mijn tv dan aangeeft dat het toch 1080i is........
