6 Digital Video (DV) Timings
9 The video standards discussed so far have been dealing with Analog TV
10 and the corresponding video timings. Today there are many more different
11 hardware interfaces such as High Definition TV interfaces (HDMI), VGA,
12 DVI connectors etc., that carry video signals and there is a need to
13 extend the API to select the video timings for these interfaces. Since
14 it is not possible to extend the :ref:`v4l2_std_id <v4l2-std-id>`
16 set/get video timings at the input and output.
18 These ioctls deal with the detailed digital video timings that define
19 each video format. This includes parameters such as the active video
21 widths etc. The ``linux/v4l2-dv-timings.h`` header can be used to get
33 the DV timings as seen by the video receiver applications use the
36 Applications can make use of the :ref:`input-capabilities` and
37 :ref:`output-capabilities` flags to determine whether the digital
38 video ioctls can be used with the given input or output.
