  • METHOD AND APPARATUS FOR VIDEO PROCESSING
    Publication number: 20130152108
    Abstract: A method and system for video processing is disclosed. A device driver interface (DDI) call for flipping or updating an overlay may be skipped or ignored, and may not be used by a user mode driver to pass overlay properties to a kernel mode driver (KMD). Instead, the overlay properties may be passed to the KMD at rendering time during a DDI call for rendering. The user mode driver may call a DDI for rendering an overlay frame while simultaneously passing the overlay property data to the KMD. The KMD may store the overlay property data in an overlay flip queue, program the overlay hardware per the overlay property data stored in the overlay flip queue, and flip the overlay in response to the vertical synchronization deferred procedure call.
