Enable support for webcams and video grabbers.
Say Y when you have a webcam or a video capture grabber board.
config MEDIA_ANALOG_TV_SUPPORT
bool "Analog TV support"
---help---
Enable analog TV support.
Say Y when you have a TV board with analog support or with a
hybrid analog/digital TV chipset.
Note: There are several DVB cards that are based on chips that
support both analog and digital TV. Disabling this option
will disable support for them.
config MEDIA_DIGITAL_TV_SUPPORT

---help---
Enable digital TV support.
Say Y when you have a board with digital support or a board with
hybrid digital TV and analog TV.

---help---
Enable support for Remote Controllers on Linux. This is
needed in order to support several video capture adapters,
standalone IR receivers/transmitters, and RF receivers.
Enable this option if you have a video capture board even
if you don't need IR, as otherwise, you may not be able to
compile the driver for your adapter.
Say Y when you have a TV or an IR device.
config MEDIA_CEC_SUPPORT

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
unsure say Y.

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