1. A method of communicating digital display data and associated auxiliary processing data from a frame buffer to a post-processor in a computer graphics system, comprising the steps of:
- storing the display data and the auxiliary processing data in the frame buffer;
forming video scan lines from the frame buffer by handling both the display data and the auxiliary processing data as video data;
extending a horizontal active line time of a digital video interface to enable the digital display data and associated auxiliary processing data to be transferred to the post processor; and
transferring the video scan lines over the digital video interface to the post-processor.

8. A method of post-processing digital display data in a computer graphics system as specified by associated auxiliary processing data, comprising the steps of:
-
storing the display data and the auxiliary processing data in a frame buffer; extending a horizontal active line time of a digital video interface to enable the digital display data and associated auxiliary processing data to be transferred to the post processor; transferring the display data and the auxiliary processing data from the frame buffer to a graphics post-processor via the digital video interface by handling both the display data and the auxiliary processing data as video data; and post-processing the display data as specified by the auxiliary processing data. - View Dependent Claims (9, 10, 11, 12, 13, 14)
