Patent Images

1. A method, comprising:

  • generating a video stream;

    tagging primitives in the video stream as background or foreground;

    processing the video stream through a 3D pipeline;

    tagging individual pixels with an attribute tag indicating background or foreground by storing the attribute tag indicating background or foreground on a metadata surface mapping to each of the individual pixels;

    storing the pixels in a frame memory and storing corresponding attribute tags in a corresponding tag memory; and

    encoding the pixels in the frame memory using the attribute tags to select a type of encoding,wherein a rasterizer in the 3D pipeline tags individual pixels with an attribute tag indicating background or foreground,wherein the rasterizer is to tag individual pixels with an attribute tag indicating moving or static by storing the attribute tag indicating moving or static on a metadata surface mapping to each of the individual pixels.
