+
+	<para>This format is not commonly used. The three components are
+separated into three sub-images or planes. The Y plane is first. The Cb plane
+immediately follows the Y plane in memory. Following the Cb plane is the Cr
+plane. All planes have on byte per pixel.</para>
+
+	<para>If the Y plane has pad bytes after each row, then the Cr
+and Cb planes have the same number of pad bytes after their rows. In other
+words, one Cx row (including padding) is exactly as long as one Y row
+(including padding).</para>
