GRAPHICS DISPLAY SYSTEM WITH WINDOW DESCRIPTORS |
摘要 |
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 chip uses window descriptors to describe logical surfaces, or windows, of graphics information to be displayed on the screen. The chip incorporates a unified memory architecture that provides a high level of system performance while conserving memory bandwidth and chip size. Video and graphics scaling capabilities as well as anti-flutter filtering capability are provided.
