That is a fascinating image. It lets you see how color information is encoded in video. The vertical green bar is a glimpse of the luma (Y) channel. To the left is the chrominance blue (Cb) and to the right is the chrominance red (Cr). But the chroma channels are (obviously) supposed to be aligned with the luma, yielding full color video. Unfortunately, I can't offer a suggestion why they aren't aligned.
