You know that 1080i refers to 1080 lines of vertical resolution interlaced. This means that instead of 30 frames per second, the TV displays 60 frames per second, where each field contains alternate lines of the image. Because the fields are refreshed so quickly, your brain interprets the signals up to 30 frames per second.

720p means 720 vertical lines of progressive scan video where every frame of signal is shown in its entirety, giving a better quality film-like appearance image.

Most HDTVs or HDTV ready television support 720p or 1080i and 720p, very few support 1080p HDTV. Part of the reason is that very few broadcasters wants to transmit signals to 1080p. The reason is that it requires 1080p significantly higher bandwidth than 1080i or 720p. And for broadcasters, bandwidth is a precious commodity. Using more bandwidth of a signal of medium _there is less room for other channels. Thus _in many cases, opting for a 1080p signal mean abandoning or degrading other channels.

Is HDTV 1080p important? Well, yes and no. Not all the benefits of video sequences much Progressive scan. Sports broadcasts and action movies look better at 720p than 1080i because there are a lot of fast movement and the interlacing in 1080i is sometimes sensitive, reduce the image quality. Films and TV shows where there are lots of fast action, better watch 1080i, since 720p highest resolution has a greater impact on quality progressive scan has little effect when there is only a small difference between image frames.

So, while the 1080p HDTV is the best of both worlds, the cost in terms of bandwidth, is very high compared to the benefit for most people most of the time.
