30	   Configuring the media subsystem can be complex, as there are
31	   hundreds of drivers and other config options.
32
33	   This menu offers option that will help the Kernel's config
34	   system to hide drivers that are out of the scope of the
35	   user needs, and disabling core support for unused APIs.
36

38	   needed to support media drivers will be enabled. Also, all

48	  By default, a media driver auto-selects all possible ancillary
49	  devices such as tuners, sensors, video encoders/decoders and
50	  frontends, that are used by any of the supported devices.
51
52	  This is generally the right thing to do, except when there
53	  are strict constraints with regards to the kernel size,
54	  like on embedded systems.
55
56	  Use this option with care, as deselecting ancillary drivers which
57	  are, in fact, necessary will result in the lack of the needed
58	  functionality for your device (it may not tune or may not have
59	  the needed demodulators).
60
