The transmission of an image begins with a scan, or reading of light intensity (luminance) information that starts at the top of the image.  

The horizontal sweep signal moves the scan points horizontally to the right side of the image.  At the same time the vertical sweep signal moves the scan point downward at a rate much slower than that of the horizontal sweep.  The resulting scan line moves horizontally to the right side of an image at a very slight downward angle.
