A graphics integrated circuit chip is used in a set-top box for controlling a
television
display. The graphics chip processes analog video input, digital video input, a
graphics input and an audio input simultaneously. The system may use anti-aliased
text and graphics to provide high quality display of graphical elements, or glyphs,
which represent an image of a character of text or graphics, on television and
other displays. The graphical elements may be superimposed over live video or arbitrary
graphics imagery.
