>&#13;      The tuner interface is a uniform way to control inputs and outputs
      on a multi-input selection device. This is primarily used for input
      selection on elements for TV- and capture-cards.
    </P
><P
>&#13;      Using this interface, it is possible to select one track from a list
      of tracks supported by that tuner-element. The tuner will then select
      that track for media-processing internally. This can, for example, be
      used to switch inputs on a TV-card (e.g. from Composite to S-video).
    </P
><P
>&#13;      This interface is currently only implemented by the Video4linux and
      Video4linux2 elements.

	interface to be
        usable, the element implementing it needs to be in the right state,
        so that the underlying device is open. This usually means the
        element needs to be at least in <CODE

        before you can use this interface. You will get confusing warnings
        if the element is not in the right state when the interface is used.
