  34          hybrid analog/digital TV chipset.
  35
  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.

  65        ---help---
  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.

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

 170          By default, a media driver auto-selects all possible i2c
 171          devices that are used by any of the supported devices.
 172
 173          This is generally the right thing to do, except when there
 174          are strict constraints with regards to the kernel size,
 175          like on embedded systems.
 176
 177          Use this option with care, as deselecting ancillary drivers which
 178          are, in fact, necessary will result in the lack of the needed
 179          functionality for your device (it may not tune or may not have
 180          the need demodulers).
 181
 182          If unsure say Y.
