Abstract: A method and system for spatially compositing digital video images with a tile pattern library. Spatial compositing uses a graphics pipeline to render a portion (tile) of each overall frame of digital video images. This reduces the amount of data that each processor must act on and increases the rate at which an overall frame is rendered. Optimization of spatial compositing depends on balancing the processing load among the different pipelines. The processing load typically is a direct function of the size of a given tile and an inverse function of the rendering complexity for objects within this tile. Load balancing strives to measure these variables and adjust, from frame to frame, the number, sizes, and positions of the tiles. The cost of this approach is the necessity to communicate, in conjunction with each frame, the number, sizes, and positions of the tiles.

Abstract: Embodiments of the present invention are directed to a method and apparatus for hardware acceleration of clipping and graphical fill in display systems. In one embodiment, all display data is presented to the display system. The display system uses its hardware to clip the undesired data, if necessary, and display the desired data.

Abstract: A live video feed is seamlessly inserted into a static background image while maintaining the proper positioning and scaling of the combined image. The current frame of the live video feed is first texturized onto a surface. The surface is a set of points that are translated to the location, e.g., latitude/longitude coordinates, of the live video source. A series of matrix transformations of the texturized surface coordinates is performed. First, the texturized surface is rotated to be tangential to the earth at the location of the live video source. Next, the texturized surface is rotated again to reflect the heading of the live video source. Lastly, the texturized surface is scaled to conform to the background image. The transformed live image is then inserted into the larger background image in its proper position and displayed.

Abstract: Automatically positioning of typographical features, such as vertical stems or horizontal segments of a character, on high contrast pixel sub-component boundaries as part of a rendering process that uses separately controllable pixel sub-components of pixels to represent different portions of the character. In order to identify the typographical features of the character that are to be aligned with high contrast pixel sub-component boundaries, topology of the character is analyzed at runtime. In display devices having vertical stripes of same-colored pixel sub-components, character legibility is increased when the left edges of stems are aligned with high contrast boundaries between pixel sub-components. Processing time and resources are conserved by performing a partial, rather than a full, topological analysis of the character.
