ABSTRACT:
A single frame buffer system is provided for displaying pixels of differing types according to standard pixel information types. Memory receives the pixel information wherein the pixel associated with each item of pixel information is further associated with a control signal for indicating the pixel type of the associated pixel. Devices for interpreting each type of pixel information to provide pixel display information are provided. Based upon the pixel type control signal, the associated pixel information is interpreted by the correct interpretation device to provide the pixel display information. The different pixel types may be graphics pixels and video pixels. In this case the output of either graphics processing circuitry or the output of video processing circuitry is selected for display according to the control signal. This single frame buffer system is effective to provide one-to-one mapping between the received pixel information and displayed pixels. The pixel type control signal may also include a signal representative of the number of consecutive pixels of one of the two pixel types.
