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.

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.

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

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

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