An Introduction to High-Definition
High-Definition video or HD video generally refers to any video system of higher resolution than standard-definition
(SD). NTSC, PAL and current DVDs are Standard Definition.
HD television (HDTV) resolution usually contains either 1080 or 720 lines of video information. In contrast, regular
digital television and DVDs are 480 lines (like NTSC) or 576 lines (like PAL/SECAM).
High-Definition video generally has an aspect ratio of 16:9 (1.78:1). Standard-definition television (SDTV) has a 4:3
(1.33:1) aspect ratio.
HD signals require a High-Definition television or computer monitor in order to be viewed. Many displays are now
being marketed as “HD-Ready” but not all can show all of the HD video information. In order to get the most out of
HD MediaBox, a display with at least 720 lines is recommended.
