Abstract: Closed caption data for video programs, such as television programs, may be used to implement a video search. In one implementation, a device may perform a search to obtain video programs that are relevant to the search. The search may be performed using an index generated from closed caption data of video programs. The device may additionally present the video programs that are relevant to the search as a matrix of reduced-in-size images sampled from the video programs that are relevant to the search query. The images may be sampled from the video programs near a position in the video programs corresponding to the positions at which the search query is relevant to the video program.

Abstract: A method may include receiving user preference information associated with display of content items. A triggering activity may be identified at a user device. Context information associated with the user device may be determined. A content item may be selected for display on the user device from a plurality of available content items based on the user preference information and the context information. The selected content item may be displayed on the user device.

Abstract: A method may include associating a plurality of graphical images with a plurality of contacts in a device having contact management functionality and displaying the plurality of graphical images to a user. The method may further include receiving a user selection of one of the plurality of graphical images; and initiating voice-based communication with the contact associated with the selected graphical image.

Abstract: A method of retrieving a directory listing includes steps of storing a plurality of directory listings, each listing searchable by a plurality of keys, each of the keys comprising a plurality of symbols selected from a subset of an alphabet; receiving a sequence of inputs each designating a plurality of the symbols; identifying a number of the directory listings having at least one of the keys consistent with the sequence of inputs; displaying candidate ones of the directory listing having the at least one of the keys consistent with the sequence of inputs; and selecting one of the candidate directory listings to be contacted.

Abstract: A method and apparatus for rendering a trimmed NURBS surface representing a mapping from U and V parametric coordinates to X, Y and Z geometric coordinates and having a trimming region bound by a trim polyline. The UV parametric surface is divided into contiguous V and V intervals intersecting to form UV rectangles, the trim polyline intersecting a subset of the UV rectangles to divide each of the UV rectangles of the subset into at least one polygon lying within the region and at least one polygon lying outside of the trimming region. For each UV rectangle intersected by the trim polyline, the vertices of each polygon within the trimming region formed by the intersection of the trim polyline and the UV rectangle is determined, and vertex data for the vertices so determined is provided to a concave polygon processor to render the polygon.

Abstract: A CSG solid modelling system 10 has a triple z-buffer architecture. For each pixel stored in a pixel memory 12 there are five storage entries grouped into five buffers including a front z-buffer (F) 16 which is employed to store the depths of a front face for a currently processed z-connected product, a back z-buffer (B) 18 which is employed to store the depths of a back face for the currently processed z-connected product and a final z-buffer (Z) 20 which stores the front faces of a displayed solid. Two other buffers are an intensity buffer (T) 22 for storing the intensities associated with the front face of the current z-connected product and a final intensity buffer (I) 24 for storing the intensities of the visible faces of the displayed solid. A bus 26 couples these various buffers together and to a processor 28 which may be a central processing unit or a peripheral processor.

Abstract: A color graphics system for displaying a plurality of polygons, based upon polygon commands supplied by a host computer. The system accepts the commands from the host and circulates them in a circular queue past a polygon processor or "painter's station" which examines each to see if it is on the line currently being processed. If the polygon is on the line, a line command or "micropainter" is generated and placed in a pipeline comprising a plurality of microprocessors, one for each picture element ("pixel") in the video scan line. The micropainters are passed from processor to processor down the pipeline, in synchronization with the video scan. Each pixel processor examines the micropainter and stores its color if the painter affects the pixel on the scan line which is assigned to that processor, and, in one embodiment, if the micropainter is painting a polygon which is higher (less in depth) than the last polygon whose color was stored in the processor.

Abstract: An on-line handwritten character recognition system utilizing a novel "closed-loop" type detector. The detector senses the direction of movement of the writing element across the writing surface, and is constrained in generation of strings of directions traveled to traverse all intervening directions between any two traveled by the writing element by requiring the detector to move only between adjacent directions.
