A typical way to scale back the amount of data demanded in digital video is by chroma subsampling (e.g., 4:four:4, four:2:two, and many others.). Because the human eye is much less delicate to information in color than brightness, the luminance data for all pixels is preserved, whilst the chrominance data is averaged for a variety of pixels in the block, and exactly the same benefit is utilized for all of them.
Pixels on Laptop screens are frequently square, but pixels used in digital video frequently have non-square aspect ratios, such as those Employed in the PAL and NTSC variants of the CCIR 601 electronic video typical as well as corresponding anamorphic widescreen formats.
