21 config MEDIA_CAMERA_SUPPORT
22 bool "Cameras/video grabbers support"
24 Enable support for webcams and video grabbers.
26 Say Y when you have a webcam or a video capture grabber board.
28 config MEDIA_ANALOG_TV_SUPPORT
29 bool "Analog TV support"
31 Enable analog TV support.
33 Say Y when you have a TV board with analog support or with a
34 hybrid analog/digital TV chipset.
36 Note: There are several DVB cards that are based on chips that
37 support both analog and digital TV. Disabling this option
38 will disable support for them.
40 config MEDIA_DIGITAL_TV_SUPPORT
41 bool "Digital TV support"
43 Enable digital TV support.
45 Say Y when you have a board with digital support or a board with
46 hybrid digital TV and analog TV.

58 Note: There are several TV cards that are based on chips that
59 support radio reception. Disabling this option will
60 disable support for them.

63 bool "Software defined radio support"
65 Enable software defined radio support.
67 Say Y when you have a software defined radio device.
69 config MEDIA_RC_SUPPORT
70 bool "Remote Controller support"
73 Enable support for Remote Controllers on Linux. This is
74 needed in order to support several video capture adapters,
75 standalone IR receivers/transmitters, and RF receivers.
77 Enable this option if you have a video capture board even
78 if you don't need IR, as otherwise, you may not be able to
79 compile the driver for your adapter.
81 Say Y when you have a TV or an IR device.

88 config MEDIA_CONTROLLER
89 bool "Media Controller API"
90 depends on MEDIA_CAMERA_SUPPORT || MEDIA_ANALOG_TV_SUPPORT || MEDIA_DIGITAL_TV_SUPPORT
92 Enable the media controller API used to query media devices internal
93 topology and configure it dynamically.
95 This API is mostly used by camera interfaces in embedded platforms.
97 config MEDIA_CONTROLLER_DVB
98 bool "Enable Media controller for DVB (EXPERIMENTAL)"
99 depends on MEDIA_CONTROLLER
102 Enable the media controller API support for DVB.
104 This is currently experimental.

142 default (NET && INET)
143 depends on NET && INET && DVB_CORE
145 This option enables DVB Network Support which is a part of the DVB
146 standard. It is used, for example, by automatic firmware updates used
147 on Set-Top-Boxes. It can also be used to access the Internet via the
148 DVB card, if the network provider supports it.
150 You may want to disable the network support on embedded devices. If

189 depends on MEDIA_ANALOG_TV_SUPPORT || MEDIA_DIGITAL_TV_SUPPORT || MEDIA_CAMERA_SUPPORT || MEDIA_SDR_SUPPORT
195 By default, a media driver auto-selects all possible ancillary
196 devices such as tuners, sensors, video encoders/decoders and
197 frontends, that are used by any of the supported devices.
199 This is generally the right thing to do, except when there
200 are strict constraints with regards to the kernel size,
201 like on embedded systems.
203 Use this option with care, as deselecting ancillary drivers which
204 are, in fact, necessary will result in the lack of the needed
205 functionality for your device (it may not tune or may not have
206 the needed demodulators).
