Simply put 720p, 1080i, and 1080p refer to the resolution of a TV and how the images are displayed on the TV. The numbers refer to the number of lines of pixels on the vertical side of the screen, and the higher the number the better the resolution of the TV's screen.
The letters after the numbers refer to the how the TV displays video. The P stands for progressive, and the I stands for interlaced. A progressive TV will draw all the vertical lines of a specific frame at the same time, while an interlaced TV draws the odd numbered lines of a frame and then the even numbered lines.
1080p will give you a better viewing experience on large TV's that are viewed at a short distance, but keep in mind that a TV can only display up to the quality of the signal that is being put into it. Most HD TV signals are 720p or 1080i so a 1080p TV will only display the signal at the level of what is being inputted. The most common 1080p signals right now are Blu-ray discs or DVD players that upconvert a DVD to a 1080p signal. I hope this helps!
