Patent ID: 7602406

Claim:
A computerized method for compositing an image within a computing system that includes a display device for displaying an image that is generated from a plurality of sources of image data, and wherein the system also includes resizing buffers as well as system memory storing computer-executable instructions which, when executed by a processing unit of the computing system, implement the method, wherein the method comprises acts of: the computing system generating a control structure having context information describing an image, the image being divided into at least a first portion, a second portion and a third portion; the computing system displaying the first image portion while the second image portion is being resized in a plurality of resizing buffers corresponding to the plurality of sources and while the third image portion is being decoded into a plurality of decode output buffers corresponding to the plurality of sources; the computing system, after resizing the second image portion, compositing and displaying the second image portion directly from the resizing buffers and without first compositing the second image portion into a separate image buffer; the computing system, upon decoding the third image portion, and while displaying the second image portion, resizing the third image portion within the plurality of resizing buffers; the computing system, after resizing the third image portion, compositing and displaying the third image portion directly from the plurality of resizing buffers and without first compositing the third image portion into a separate image buffer.
