This option enables DVB Network Support which is a part of the DVB

standard. It is used, for example, by automatic firmware updates used

DVB card, if the network provider supports it.

You may want to disable the network support on embedded devices. If

|
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.
