HD Formats: Color Model & Color Sub-Sampling

HD Formats: Color Model & Color Sub-Sampling: "
If you’ve been following my HD Formats series (Video Formats, Bit Depth & Bit Rate), this blog should help clarify a couple more of those words and numbers we see associated with HD video formats. First, I’ll talk about different color models in the HD world, which are often shown as ‘Y Cb Cr’, ‘Y Pb Pr’ or ‘RGB’. Then I’ll cover color sub-sampling, which is most often described by a combination of numbers such as 4:2:2 or 4:2:0. These two terms are closely associated with one another, but have very different implications.
