The media_devnode structure provides support for registering and unregistering character devices using a dynamic major number. Reference counting is handled internally, making device drivers easier to write without having to solve the open/disconnect race condition issue over and over again. The code is based on video/v4l2-dev.c.

Enable this if you own a DVB/ATSC adapter and want to use it or if
|
|
you compile Linux for a digital SetTopBox.
|

|
Say Y when you have a DVB or an ATSC card and want to use it.
