In the past, it was possible to have either DVB or V4L2 core as module and the other as builtin. Such config never make much sense, and created several issues in order to make the Kconfig dependency to work, as all drivers that depend on both (most TV drivers) would need to be compiled as 'm'. Due to that, the VIDEO_MEDIA config option were added. Instead of such weird approach, let's just use the MEDIA_SUPPORT =y or =m to select if the media subsystem core will be either builtin or module, simplifying the building system logic. Also, fix the tuners configuration, by enabling them only if a tuner is required. So, if just webcam/grabbers support is selected, no tuner option will be selected. Also, if only digital TV is selected, no analog tuner support is selected. That removes the need of using EXPERT customise options, when analog TV is not selected.

This option enables DVB Network Support which is a part of the DVB

standard. It is used, for example, by automatic firmware updates used

on Set-Top-Boxes. It can also be used to access the Internet via the

DVB card, if the network provider supports it.
|

You may want to disable the network support on embedded devices. If
