Closed Captioning is the "fairly slow" text that is sent (usually on line 21
of the Vertical Blanking Interval (VBI)) that can be displayed during a TV
show or commercial.  If you understand Teletext then think of it as slower
Teletext.  But in the case of CC it is meant to be displayed over the top of
the picture instead of fullscreen.
CC includes commands to position the text, set colors, etc...
(It is now required here in the US to be in every Television....)
