ABSTRACT:
A multimedia display system includes a central processing unit, a storage device associated with the central processing unit, a standard interface bus to which the central processing unit and the storage device are connected, a graphics processor connected to the bus for generating graphics data in response to commands from the central processor, a digitizer for converting an analog video signal to digital form and for producing synchronization signals, a video processor for processing the digitized video data to produce pixel representations of the digitized video signal, a shared frame buffer for storing the graphics data generated by the graphics processor and the pixel representations of the video signal, a device for converting the stored digital data to a data stream appropriate for driving a video monitor, and a video monitor for displaying the graphics data and the video information, wherein the video processor generates a programmable variable phase vertical synchronization signal for synchronizing video data and graphics data through a shared frame buffer with the capacity to handle relocatable windows.
