Today there are many more different -hardware interfaces such as High Definition TV interfaces (HDMI), VGA, -DVI connectors etc., that carry video signals and there is a need to -extend the API to select the video timings for these interfaces. Since -it is not possible to extend the :ref:`v4l2_std_id <v4l2-std-id>` -due to the limited bits available, a new set of ioctls was added to -set/get video timings at the input and output. - -These ioctls deal with the detailed digital video timings that define -each video format. This includes parameters such as the active video -width and height, signal polarities, frontporches, backporches, sync -widths etc. The ``linux/v4l2-dv-timings.h`` header can be used to get -the timings of the formats in the :ref:`cea861` and :ref:`vesadmt` -standards. - -To enumerate and query the attributes of the DV timings supported by a -device applications use the -:ref:`VIDIOC_ENUM_DV_TIMINGS` and -:ref:`VIDIOC_DV_TIMINGS_CAP` ioctls. To set -DV timings for the device applications use the -:ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl and to get -current DV timings they use the -:ref:`VIDIOC_G_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl. To detect -the DV timings as seen by the video receiver applications use the -:ref:`VIDIOC_QUERY_DV_TIMINGS` ioctl. - -Applications can make use of the :ref:`input-capabilities` and -:ref:`output-capabilities` flags to determine whether the digital -video ioctls can be used with the given input or output. |
