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

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.
