US Patent 7451457 Facilitating interaction between video renderers and graphics device drivers

Facilitating interaction may be enabled through communication protocols and/or APIs that permit information regarding image processing capabilities of associated graphics hardware to be exchanged between graphics device drivers and video renders. In a first exemplary media implementation, electronically-executable instructions thereof for a video renderer precipitate actions including: issuing a query from a video render towards a graphics device driver, the query requesting information relating to process amplifier (ProcAmp) capabilities; and receiving a response at the video renderer from the graphics device driver, the response including the requested information relating to ProcAmp capabilities. In a second exemplary media implementation, a graphics device driver precipitates actions including: receiving a query at the graphics device driver from a video renderer, the query requesting information relating to ProcAmp capabilities; and sending a response to the video renderer from the graphics device driver, the response including the requested information that relates to ProcAmp capabilities.
