How much should we reduce the chroma resolution?! It turns out that there are already some schemas that describe how to handle resolution and the merge (`final color = Y + Cb + Cr`).
These schemas are known as subsampling systems (or ratios), they are identified by the numbers: **4:4:4, 4:2:3, 4:2:1, 4:1:1, 4:2:0, 4:1:0 and 3:1:1**. And each one of them defines how much should we discard in the chroma resolution as well as how we should merge the three planes (Y, Cb, Cr).
