15Description
16===========
17
18In this format each four bytes is two pixels. Each four bytes is two
19Y's, a Cb and a Cr. Each Y goes to one of the pixels, and the Cb and Cr
20belong to both pixels. As you can see, the Cr and Cb components have
21half the horizontal resolution of the Y component.
