Standard Definition (SDTV) is a term used to describe a picture that looks pretty much like your old analog pictures. The picture from a DVD is SDTV; it isn’t even close to true HDTV. The traditional “analog” picture was made up of 480 active picture lines. High definition TV uses up to 1080 lines, delivering a vivid display with incredible detail. Standard Definition TV (SDTV) is pretty much any picture that is not High Definition TV.
