The GstTuner interface is provided by elements that have the ability to
tune into multiple input signals, for example TV or radio capture cards.
</p>
<p>
The interpretation of 'tuning into' an input stream depends on the element
implementing the interface. For v4lsrc, it might imply selection of an
input source and/or frequency to be configured on a TV card. Another 
GstTuner implementation might be to allow selection of an active input pad
from multiple input pads.
</p>
<p>
That said, the GstTuner interface functions are biased toward the
TV capture scenario.
</p>
<p>
The general parameters provided are for configuration are:

<li class="listitem">Selection of a current <a class="link" href="gst-plugins-base-libs-gsttunerchannel.html#GstTunerChannel"><span class="type">GstTunerChannel</span></a>. The current channel
represents the input source (e.g. Composite, S-Video etc for TV capture).
</li>
<li class="listitem">The <a class="link" href="gst-plugins-base-libs-gsttunernorm.html#GstTunerNorm"><span class="type">GstTunerNorm</span></a> for the channel. The norm chooses the
interpretation of the incoming signal for the current channel. For example,
PAL or NTSC, or more specific variants there-of.
</li>
<li class="listitem">Channel frequency. If the current channel has the ability to tune
between multiple frequencies (if it has the GST_TUNER_CHANNEL_FREQUENCY flag)
then the frequency can be changed/retrieved via the
