  34          hybrid analog/digital TV chipset.
  35

  37                support both analog and digital TV. Disabling this option
  38                will disable support for them.

  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.
  69
  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.
  73
  74          Say Y when you have a TV or an IR device.

 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.

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