Abstract
A VPM (Video Port Manager) provider, which performs such control as to allow a VGA (Video Graphic Array) controller to effectively receive moving picture data from a ZV (Zoomed Video) port, acquires display environment information about the system display performance and the current display mode from a VGA BIOS (Video Graphic Array Basic Input Output System), and determines the maximum resolution of moving pictures displayable by the system based on that display environment information. When the resolution specified in the moving picture display request from a VPM client is greater than the displayable maximum resolution of moving pictures, the optimal data conversion processing needed to display moving picture data without causing a display disturbance and with a resolution closest to the specified resolution, such as data compression, frame thinning or line thinning, is performed on that moving picture data.
