/dev/video with major 81 is the Video4Linux interface. When opened you can
apply the V4L ioctl macros (VIDIOC*) defined in videodev.h. Have a look at
/usr/src/linux/Documentation/video4linux/API.html.

/dev/ost/* with major 250 form the DVB APInterface. There you can apply
file operations described in the DVB API documentation & defined in
ost/include/ost/*.h.
