Abstract: The claimed subject matter relates to a computer-implemented architecture that can generate a map. The map can be a hybrid between an orthographic projection map and street-side images, thus including useful aspects from both types of representations. For example, an orthographic projection map is very effective at presenting global relationships among the features of the map but not effective at presenting local detail. In contrast, street -side images show excellent detail but do not convey the global information of an orthographic projection map. The hybrid map can thus provide a richer set of information than conventional maps and can also display objects/features of the hybrid map in multiple perspectives simultaneously on a single representation that is printable.

Abstract: Methods and apparatus for processing data representing multiple image sequences, e.g., TV programs, and displaying multiple images from different video sequences in different windows of a single display screen are disclosed. The amount of system resources required to process and display the image data are a function of the size of the windows in which the images are displayed. In accordance with the present invention demand for system resources is assessed and compared to the amount of available system resources. If the demand for system resources will exceed the available system resources, the size of one or more of the windows used to display secondary images, e.g., the small PIP windows, is reduced to reduce the burden, e.g., processing or bus bandwidth burden, on one or more system resources. In one embodiment, the system suggests a set of window sizes to the user which will allow for the decoding and display of programs without exceeding the available system resources.

Abstract: A cable test application is run in the host computer to determine whether the PC to printer connection is able to maintain at least a predetermined speed of data transfer. The cable test provides an accurate measure of the true throughput of the I/O connection during a print job, for example by sending special blocks of data, each tagged so that it is recognizable by the printer firmware's formatter as a "speed test block" that may be discarded after it has been processed, not only by the printer firmware's I/O process, but also by the downstream formatter process. This provides a more accurate measure of data transmission speed than simply having the I/O process throw away not yet formatted test data, and does not require the waste or spoilage of any print media or other expendable supplies.

Abstract: In an information picture display device using a double-picture type screen, a TV microcomputer controls a double window processing unit, an information processing unit processes information data received from a value added network and recognizes a selected screen mode to then output a switching control signal. The device is constructed so that the output of a switching unit for selecting one of a sub-video signal and a signal processed in the information processing unit is input to the double window processing unit, thereby displaying an information signal on the entire double-picture type screen, displaying the information signal and a TV signal separately on partitions of the double-picture type screens, or displaying the information signal superimposed on the TV signal. When the information signal is displayed on the entire screen, the signal processed in the information processing unit is displayed directly without passing through the double window processing unit, thereby improving picture quality.

Abstract: The invention is a method used with a system for compositing a foreground scene including a subject before a nonuniformly illuminated colored backing, and a background scene, and where the nonuniformity is nonlinear from side to side and/or nonlinear from top to bottom. A window is employed to mask unwanted areas outside of, or on, the colored backing and one or more window edges form a visible join line where the window edges join the backing. The visible join line is made nonvisible without affecting the subject by a horizontal and vertical linear interpolation method for obtaining backing corrections that cause the backing level control signal to be uniform at the window edges and match an assigned window signal level.
