HD stands for High Definition. HDMI stands for High Definition Multimedia Iterface. HDMI is the input for 1080p HD programming. HD is the actual resolution 1920x1080p is the standard for HD currently. It stands for 1920 horizontal lines and 1080 vertical lines (This creaes a little over 2 megapixlels). These lines refresh to create the image and the more lines the beter quality that you see. the p stands for progressive scan where the entire image is refreshed at once. 1080i is interlaced so half the lines refresh and the other half next. The time between the two is very miniscule. 720p is also HD by the way and it is shown with component cables (this also shows 1080i). The HDMI cable and port transmits 1080p image. Most HD progamming on cable and satellite is 720p although 1080p is used on some PPV chanels. Blu-ray is completely 1080p. DVD's don't use HD although they can be upconverted in a blu-ray player, but it won't be quite as good as a blu-ray disc.
