GstTuner is an interface for controlling capture devices with tuners. That
includes things like setting the input channel (S-Video/Composite etc) and
the norm (PAL/NTSC).

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gsttuner.html has a little bit of info, but really it's another one of those pieces of documentation that could stand to be improved. The best reference is the code for something which implements the tuner interface, like v4lsrc or v4l2src.
