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.

63 bool "Remote Controller support"
66 Enable support for Remote Controllers on Linux. This is
67 needed in order to support several video capture adapters,
68 standalone IR receivers/transmitters, and RF receivers.
70 Enable this option if you have a video capture board even
71 if you don't need IR, as otherwise, you may not be able to
72 compile the driver for your adapter.
74 Say Y when you have a TV or an IR device.

82 bool "Media Controller API"
83 depends on MEDIA_CAMERA_SUPPORT
85 Enable the media controller API used to query media devices internal
86 topology and configure it dynamically.
88 This API is mostly used by camera interfaces in embedded platforms.

129 This option enables DVB Network Support which is a part of the DVB
130 standard. It is used, for example, by automatic firmware updates used
131 on Set-Top-Boxes. It can also be used to access the Internet via the
132 DVB card, if the network provider supports it.
134 You may want to disable the network support on embedded devices. If

173 bool "Autoselect ancillary drivers (tuners, sensors, i2c, frontends)"
174 depends on MEDIA_ANALOG_TV_SUPPORT || MEDIA_DIGITAL_TV_SUPPORT || MEDIA_CAMERA_SUPPORT
180 By default, a media driver auto-selects all possible ancillary
181 devices such as tuners, sensors, video encoders/decoders and
182 frontends, that are used by any of the supported devices.
184 This is generally the right thing to do, except when there
185 are strict constraints with regards to the kernel size,
186 like on embedded systems.
188 Use this option with care, as deselecting ancillary drivers which
189 are, in fact, necessary will result in the lack of the needed
190 functionality for your device (it may not tune or may not have
191 the needed demodulators).
