This is useful to test teletext capture applications like alevt and mtt. It also fixes a previously undetected bug where the PAL VBI start line of the second field was off by one. Using the new field start defines helps a lot fixing such bugs. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
