The V4L and DVB API's are there for a long time. however, up to now, no efforts were done to merge them to kernel DocBook. This patch adds the current versions of the specs as an unique compendium. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

<para>This is commonly the native format of digital cameras,
|
|
reflecting the arrangement of sensors on the CCD device. Only one red,
|
|
green or blue value is given for each pixel. Missing components must
|
|
be interpolated from neighbouring pixels. From left to right the first
|
|
row consists of a green and blue value, the second row of a red and
|
|
green value. This scheme repeats to the right and down for every two
|
|
columns and rows.</para>
