+	The video standards discussed so far has been dealing with Analog TV and the
+corresponding video timings. Today there are many more different hardware interfaces
+such as High Definition TV interfaces (HDMI), VGA, DVI connectors etc., that carries
+video signals and there is a need to extend the API to allow settings video timings
+ on these interfaces. Since it is not possible to extend the v4l2-std-id due to
+the limited bits available, a new set of IOCTLs are added to set/get video timings at
+the input and output:- </para><itemizedlist>
+	<listitem>
+	<para> DV Presets :- Digital Video (DV) presets. These are IDs representing a
+video timing at the input/output. Presets can be thought of pre-defined timings implemented
+by the hardware like standards. A __u32 data type is used to represent a preset unlike the
+ bit mask that is used in &v4l2-std-id; allowing future extensions to support many
+different presets as needed</para>
+	</listitem>
+	<listitem>
+	<para> Custom DV Timings :- This will allow applications to define a more detailed
+custom video timings at the interface. This includes parameters such as width, height,
+ polarities, frontporch, backporch etc.
+	</para> 
+	</listitem>
+	</itemizedlist>
+	<para> To Enumerate and query the attributes of DV presets supported by a device,
+ applications use the &VIDIOC-ENUM-DV-PRESETS; ioctl. To Get the current DV preset,
+ application use the &VIDIOC-G-DV-PRESET; ioctl and to Set a preset it uses the 
+ &VIDIOC-S-DV-PRESET; ioctl.</para>
+	<para> To Set a Custom DV timings at the device, applications use the
+ &VIDIOC-S-DV-TIMINGS; ioctl and to Get current Custom DV timings, it uses the
+ &VIDIOC-G-DV-TIMINGS; ioctl.</para>
+	<para> Applications can make use of the <xref linkend="input-capabilities" /> and
+<xref linkend="output-capabilities"/> flags to decide what ioctls available to set the
+video timings at the device.</para>

+video signals and there is a need to extend the API to allow settings video timings
+ on these interfaces. Since it is not possible to extend the v4l2-std-id due to
