While 16:9 (1.7 7:1) was initially selected as a compromise format, the subsequent popularity of HD broadcast has solidified 16:9 as perhaps the most common video aspect ratio in use. [7] Most 4:3 (1.3 3:1) and 21:9 video is now recorded using a "shoot and protect" technique that keeps the main action within a 16:9 (1.7 7:1) inner rectangle to ...

Many digital video cameras have the capability to record in 16:9 (= 4 2:3 2), and 16:9 is the only widescreen aspect ratio natively supported by the DVD standard. DVD producers can also choose to show even wider ratios such as 1.66:1, 1.75:1, 1.77:1 and 1.78:1 [ 1 ] within the 16:9 DVD frame by hard matting or adding black bars within the image ...
In the 1990s, widescreen televisions offered a wider 16:9 aspect ratio (1.78 times the height instead of 1.33) and allowed films with aspect ratios of 1.66:1 and 1.85:1 to fill most or all of the screen, with minimal letterboxing or cropping required. DVD packaging began to use the expression, "16:9 – Enhanced for Widescreen TVs."
The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio.
480p is the shorthand name for a family of video display resolutions.The p stands for progressive scan, i.e. non-interlaced.The 480 denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio (480 × 4 ⁄ 3 = 640) or a horizontal resolution of 854 (848 should be used for mod16 compatibility) [1] pixels for an approximate 16:9 aspect ...
The same frame size is used for 4:3 and 16:9 frame aspect ratios, resulting in different pixel aspect ratios for fullscreen and widescreen video. [ 8 ] [ 9 ] Prior to the DCT compression stage, chroma subsampling is applied to the source video in order to reduce the amount of data to be compressed.
