*
* <refsect2>
* <para>
* The GstTuner interface is provided by elements that have the ability to
* tune into multiple input signals, for example TV or radio capture cards.
* </para><para>
* 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.
* </para><para>
* That said, the GstTuner interface functions are biased toward the
* TV capture scenario.
* </para><para>
* The general parameters provided are for configuration are:
* <itemizedlist>
* <listitem>Selection of a current #GstTunerChannel. The current channel
* represents the input source (e.g. Composite, S-Video etc for TV capture).
* </listitem>
* <listitem>The #GstTunerNorm 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.
* </listitem>
* <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
* gst_tuner_set_frequency() and gst_tuner_get_frequency() methods.
* </listitem>
* </itemizedlist>
* </para>

* Where applicable, the signal strength can be retrieved and/or monitored
