Standard Definition Standard-definition television (SDTV) is a television system that uses a resolution that is not considered to be either high-definition television (HDTV 720p and 1080p) or enhanced-definition television (EDTV 480p). The two common SDTV signal types are 576i, with 576 interlaced lines of resolution, derived from the European-developed PAL and SECAM systems; and 480i based on the American National Television System Committee NTSC system.

High Definition HD video has higher resolution than SD video, which results in a sharper picture. Typical HD display resolution will be 1,280×720 pixels (720p) or 1,920×1,080 pixels (1080i/1080p).
