23 YUV formats commonly encode images with a lower resolution for the chroma
26 differences, is called chroma subsampling.
39 Subsampling the chroma component effectively creates chroma values that can be
42 - .. _yuv-chroma-centered:
44   The subsampled chroma value may be calculated by simply averaging the chroma
45   value of two consecutive pixels. It effectively models the chroma of a pixel
47   interstitially sited chroma.
49 - .. _yuv-chroma-cosited:
51   The other option is to subsample chroma values in a way that place them in
53   other chroma sample (creating aliasing artifacts), or with filters using an
54   odd number of taps. This is referred to as co-sited chroma.
