The big difference is simply how detailed your image is going to be. SDTV images may look fine on a small scale, but stretch it out over a larger screen, and you will see the quality drop pretty quick. Another example is how defined the details are.

Thank you. What is the difference between i, p, p, i, and p? If you have not been following the changes in television technology in the last few years, the onslaught of acronyms and terms can be daunting. Before tackling the differences between i, p, p, i, and p -- which in basic terms refer to the width of the image -- it is worthwhile to know that the "i" suffix stands for "interlaced" and the "p" suffix stands for "progressive". Interlaced means that a single frame of television is presented in two parts -- first the television "loads" every other line of the picture 2, 4, 6, and so on , and then it loads the remaining lines 1, 3, 5, etc.

Progressive means that all lines of the picture are loaded simultaneously, which can make a substantial difference in picture quality, particularly with fast moving images -- sports, action movies, and so forth. SDTV -- which basically is the same as analog television, but transmitted digitally so that there is no signal loss regardless of distance -- is offered in i, EDTV is offered in p, and HDTV is offered in p, i, and p.

There are differences in aspect ratios or -- the ratio between the width and height of the display -- as well. For more details -- in addition to history and advantages and disadvantages of each standard -- please refer to the excellent Projector Central website.
