It was first defined in the H.261 standard in 1988.
Aspect Ratio The ratio of width to height for the frame of the televised picture. 4:3 for standard systems, 5:4 for 1K x 1K, and 16:9 for HDTV. ATSC An acronym for "Advanced Televisions System Committee", the organization that defines the standard for high-definition TV in the United States. Attenuation In general terms, a reduction in signal ...
The display aspect ratio (DAR) is the aspect ratio of a display device and so the proportional relationship between the physical width and the height of the display. It is expressed as two numbers separated by a colon ( x : y ), where x corresponds to the width and y to the height.
1080p Full HD – digital video format with a horizontal resolution of 1920×1080; 1440p – digital video format with a vertical resolution of 1440, aimed at non-television computer monitor usage; 21:9 aspect ratio – a common widescreen cinema aspect ratio; 4K resolution – digital video formats with a horizontal resolution of around 4,000 ...

Applications of the 1080p standard include television broadcasts, Blu-ray Discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movies, consumer-grade televisions and projectors, computer monitors and video game ...
Storage aspect ratio is the ratio of the image width to height in pixels, and can be easily calculated from the video file. Display aspect ratio is the ratio of image width to height (in a unit of length such as centimeters or inches) when displayed on screen, and is calculated from the combination of pixel aspect ratio and storage aspect ratio.
The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, [ 1 ] [ 2 ] when the rectangle is oriented as a " landscape ".
