High-definition television (HDTV) is a television system that transmits and displays video at a much higher resolution than conventional standard-definition (SD) broadcasts. It typically uses 720p, 1080i, or 1080p resolution with a 16:9 aspect ratio, and assumes digitally compressed transmission. As a subtopic of the video-related pages, this page collects reference material on the HDTV concept.
