To compare 1080i and 1080p, it is important to compare frame-rates. Due to interlacing, 1080i has twice the frame-rate but half the resolution of a 1080p signal using the same bandwidth, although, also due to interlacing, 1080i looks to be the same resolution, although with more flicker. Faster frame-rates are especially useful in sports shows and other shows with fast-moving action. However, on some flat screens that do not support interlacing, this instead becomes smeared or jarred artifacts.
Current digital television broadcast systems and standards are not equipped for 1080p50/60 transmission. Also, the majority of consumer televisions offered for sale are currently not equipped to receive or decode a 1080p signal at any frequency. It is less bandwidth-intensive to broadcast a film at 1080p24 than 1080i30, since 20% less data would be transferred.
