Closing a Video Stream Object
First Claim
1. A method for closing a video stream object between a rendering process and a graphics device having an associated graphics device driver, the method comprising:
- issuing, by a rendering process, a close stream call having at least one call parameter comprising a stream identifier corresponding to a previously established video stream object; and
receiving, by a supporting process, said close stream call and parsing said close stream call to retrieve said at least one call parameter, and causing said supporting process to close said previously established video stream object.

Abstract
Techniques are provided for facilitating processing of interlaced video images for progressive video displays. A method receives from a renderer a query for a graphics device driver to a graphics processing capability that can be performed by an associated graphics device in de-interlacing video data, communicating the query to the graphics device driver, receiving from the graphics device driver a response to the query that identifies the graphics processing capabilities to the renderer, and communicating the response to the renderer. The method includes receiving from the renderer a further query for the graphics device driver to at least one input requirement associated with the identified graphics processing capability, communicating the further query to the graphics device driver, receiving from the graphics device driver a further response to the further query that identifies the input requirement(s) associated with the graphics processing capability, and communicating the further response to the renderer.
