4:4:4 format
This format corresponds to the digitization of the three primaries at a frequency of 13.5 MHz each. It is also the format used for calculating luminance and chrominance components when this is done digitally. It can give the 4:2:2 format.

Format 4:4:4:4
This format is identical to 4:4:4, with the addition of a cutting plane. It is used particularly in post-production and can also give 4:2:2.
-
4:2:0 format
This format is obtained from 4:2:2. Luminance is unchanged, with all samples retained. For chrominance, the same principle applies vertically as horizontally. Every second chrominance sample is retained; this is achieved by filtering between two consecutive lines....
