721 <para>
722 The video standards discussed so far has been dealing with Analog TV and the
723corresponding video timings. Today there are many more different hardware interfaces
724such as High Definition TV interfaces (HDMI), VGA, DVI connectors etc., that carry
725video signals and there is a need to extend the API to select the video timings
726for these interfaces. Since it is not possible to extend the &v4l2-std-id; due to
727the limited bits available, a new set of IOCTLs is added to set/get video timings at
728the input and output: </para><itemizedlist>
729 <listitem>
730 <para>DV Presets: Digital Video (DV) presets. These are IDs representing a
731video timing at the input/output. Presets are pre-defined timings implemented
732by the hardware according to video standards. A __u32 data type is used to represent
733a preset unlike the bit mask that is used in &v4l2-std-id; allowing future extensions
734to support as many different presets as needed.</para>
735 </listitem>
736 <listitem>
737 <para>Custom DV Timings: This will allow applications to define more detailed
738custom video timings for the interface. This includes parameters such as width, height,
739polarities, frontporch, backporch etc.
740 </para>
741 </listitem>
742 </itemizedlist>
743 <para>To enumerate and query the attributes of DV presets supported by a device,
744applications use the &VIDIOC-ENUM-DV-PRESETS; ioctl. To get the current DV preset,
745applications use the &VIDIOC-G-DV-PRESET; ioctl and to set a preset they use the
746&VIDIOC-S-DV-PRESET; ioctl.</para>
747 <para>To set custom DV timings for the device, applications use the
748&VIDIOC-S-DV-TIMINGS; ioctl and to get current custom DV timings they use the
749&VIDIOC-G-DV-TIMINGS; ioctl.</para>
750 <para>Applications can make use of the <xref linkend="input-capabilities" /> and
751<xref linkend="output-capabilities"/> flags to decide what ioctls are available to set the
752video timings for the device.</para>
