ABSTRACT:
A method and apparatus for a computer graphics system identifies the format of video pixel data in a data stream having a plurality of data formats including a first pixel data format and a second pixel data format, the second pixel data format being a YUV format. The method comprises the steps of (a) receiving pixel data; (b) selecting an output channel in response to at least one particular value of at least one bit of each received pixel datum wherein the particular value identifies the data format as either the first pixel data format or the YUV format; and (c) providing the pixel data to the selected output channel. Also provided is a circuit in a video graphics controller and a computer system having such circuit according to the method.
