High-definition television (HDTV) provides a resolution that is substantially higher than that of standard-definition television.
HDTV may be transmitted in various formats:
1080p - 1920×1080p: 2,073,600 pixels (approximately 2.1 megapixels) per frame
1080i - typically either:
1920×1080i: 1,036,800 pixels (approximately 1 megapixel) per field or 2,073,600 pixels (approximately 2.1 megapixels) per frame
1440×1080i:[1] 777,600 pixels (approximately 0.8 megapixels) per field or 1,555,200 pixels (approximately 1.6 megapixels) per frame
720p - 1280×720p: 921,600 pixels (approximately 0.9 megapixels) per frame
The letter "p" here stands for progressive scan while "i" indicates interlaced.
When transmitted at two megapixels per frame, HDTV provides about five times as many pixels as SD (standard-definition television)
