摘要： A method for generating a font for display on an interlaced monitor which is relatively free of the distorting effects of interlacing. The method operates by obtaining an original bitmap for a character in the font which is larger than a desired size for the font. This original bitmap is subjected to a weighted filtering to produce a filtered bitmap. The filtered bitmap is reduced to a desired font size by dividing the filtered bitmap into a plurality of tiles. Each tile is subjected to an unweighted filtering to produce an average value, which is rounded to produce a value for a corresponding pixel in a reduced bitmap. Next, the reduced bitmap is quantized to form a bitmap for display by setting all values which exceed an upper quantization limit to the upper quantization limit, and if necessary, setting all values which are below a lower quantization limit to the lower quantization limit. If a color display is used, pixels within the bitmap for display are used to index a color map, which contains a range of blendings of a font color with a background color, to produce a color bitmap for display. Coefficients in the weighted filtering process can be iteratively adjusted to achieve a satisfactory display of characters within the font on an interlaced monitor.

摘要： An architecture for an information appliance adapted for a specific application supports a variety of appliance personalities, relying on a single core technology. The information appliance comprises an application-optimized hardware platform, including a processor, a display coupled to the processor, an input/output device coupled to an information source and to the processor, a user input device, and working memory coupled to the processor. Non-volatile memory is coupled to the processor and stores appliance operating software and application software. The appliance operating software includes logic executed by the processor, which manages information flow from the information source through the working memory to the display, and the application software includes logic executed by the processor and responsive to the user input to manage selection of information from the information source. The appliance operating software includes an operating system kernel that is adapted for the processor, and a system library that includes logic providing an interface to the application software. An operating system service layer provides an abstraction function between the system library and the appliance operating system kernel and hardware, so that the logic in the system library and above, such as in the application itself, is executable with a development platform operating system which is completely different from the operating system of the appliance.
