1080line

1080line is a term used in video and display technology to denote an image format defined by 1080 lines of vertical resolution. The concept appears in historical technical literature and production notes to distinguish image quality by the number of scan lines rather than by pixel count alone. In modern usage, 1080 lines typically correspond to Full HD content with a frame resolution of 1920×1080. The image is usually displayed in a 16:9 aspect ratio and can be delivered as progressive scan (1080p) or interlaced scan (1080i).

In practice, 1080line content supports a range of frame rates depending on the delivery method. 1080p is a progressive format that can run at common frame rates such as 24, 30, or 60 frames per second. 1080i is an interlaced format that effectively yields 25 or 30 frames per second in many region-specific broadcasts. The distinction between 1080line as a descriptor and the specific 1080p/1080i formats is often historical or contextual, with modern discussions preferring explicit format labels.

Historically, the 1080-line concept emerged during HDTV development in the late 20th century, as engineers defined resolution targets for high-definition broadcasting. Over time, 1920×1080 became the standard reference for Full HD in consumer electronics, broadcasts, and Blu-ray discs. Today the term 1080line is less common in consumer specifications, being largely superseded by explicit format names such as 1080p and 1080i, while remaining a shorthand in some technical writings.
