Methods and apparatuses for facilitating processing of interlaced video images for progressive video displays
First Claim
1. A method for use in manipulating interlaced video data, the method comprising:
- accessing said interlaced video data including top field data and bottom field data associated with a video surface having a width, a height, and a stride; and
producing a reinterpreted video surface by;
isolating said top field data and said bottom field data, andconfiguring said isolated top field data and said isolated bottom field data in said reinterpreted video surface such that said reinterpreted video surface has a reinterpreted height that is less than said height and a reinterpreted stride that is greater than said stride.

Abstract
Methods and apparatuses are provided for facilitating processing of interlaced video images for progressive video displays. In accordance with certain exemplary implementations, a method includes receiving from a renderer a query for a graphics device driver as to at least one 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 capability/capabilities to the renderer, and communicating the response to the renderer. The method further includes receiving from the renderer a further query for the graphics device driver as 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.

9. An apparatus configurable to convert interlaced video data to corresponding progressive video data, the apparatus comprising:
-
memory having interlaced video data including top field data and bottom field data associated with a video surface having a width, a height, and a stride; and logic operatively coupled to said memory and configured to access said interlaced video data to produce a reinterpreted video surface by isolating said top field data and said bottom field data, and configuring said isolated top field data and said isolated bottom field data in said reinterpreted video surface such that said reinterpreted video surface has a reinterpreted height that is less than said height and a reinterpreted stride that is greater than said stride. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
