+ (Digital Visual Interface), HDMI (<xref linkend="hdmi" />) and DisplayPort (<xref linkend="dp" />).

+
+ <para>Note that these devices can have multiple input or output pads which are

+ transmit video from/to only one of those pads, the other pads can still be
+ active when it comes to EDID (Extended Display Identification Data,
+ <xref linkend="vesaedid" />) and HDCP (High-bandwidth Digital Content
+ Protection System, <xref linkend="hdcp" />) processing, allowing the device
+ to do the fairly slow EDID/HDCP handling in advance. This allows for quick
+ switching between connectors.</para>
+
+ <para>These pads appear in several of the controls in this section as
+ bitmasks, one bit for each pad. Bit 0 corresponds to pad 0, bit 1 to pad 1,
+ etc. The maximum value of the control is the set of valid pads.</para>

+
+ <para>This is a multi-planar format, as opposed to a packed format.
+The three components are separated into three sub-images or planes.
+
+The Y plane is first. The Y plane has one byte per pixel. The Cr data
+constitutes the second plane which is half the width and half
+the height of the Y plane (and of the image). Each Cr belongs to four
+pixels, a two-by-two square of the image. For example,
+Cr<subscript>0</subscript> belongs to Y'<subscript>00</subscript>,
+Y'<subscript>01</subscript>, Y'<subscript>10</subscript>, and
+Y'<subscript>11</subscript>. The Cb data, just like the Cr plane, constitutes
+the third plane. </para>
+
+ <para>If the Y plane has pad bytes after each row, then the Cr
+and Cb planes have half as many pad bytes after their rows. In other
+words, two Cx rows (including padding) is exactly as long as one Y row
+(including padding).</para>
+
+ <para><constant>V4L2_PIX_FMT_YVU420M</constant> is intended to be
+used only in drivers and applications that support the multi-planar API,
+described in <xref linkend="planar-apis"/>. </para>
