What Is High Definition And How Is It Different From Standard Definition?
High Definition or "HD" is a technological leap forward from standard definition, with up to 6x the picture resolution, so that what you see is sharper and more realistic.  Regular TVs and the TV channels you watch at home are typically in standard definition (unless you watch HD channels).  DVD are also in standard definition.  Standard definition (480i & 480p) is lower quality than high definition.  Many older TV sets are standard def, and can only show standard def content (programming).  Many new TVs are called High Definition TVs (HDTV).  They are capable of showing high def content in: 720p, 1080i, and 1080p, all high definition formats, but 1080p provides the highest picture quality of them all.
