Abstract: A status parameter is set for a storage area of a computer system to a read-only status. An access key is received from an access key call by a caller. The status parameter is changed to a write-permissible status if the access key matches a master access key. A request to perform a write to the storage area is received, and the write is allowed only if the status parameter has been set to the write-permissible status. The status parameter is reset to the read-only status after the write is performed.

Abstract: Image signals are converted from one color format to another using a lookup table based on interleaved indices generated from the components in the first color format. In a preferred embodiment, image signals in a YUV format are converted to image signals in a CLUT format by interleaving bits from the U and V components and appending bits from the Y component. By interleaving the U and V components, cache efficiency is improved when color conversion is implemented on a general-purpose processor with limited on-chip cache.

Abstract: A request to erase a storage area of a computer system is received via an erase call by a caller, the erase call containing an erasure key. The storage area is erased only if the erasure key matches a master erasure key corresponding to the storage area. A request is received to perform a write to the storage area, and the write is allowed only if the storage area has been erased.

Abstract: A multimedia architecture for pre-fetching data from a server provides limited-memory client machines with the ability to take advantage of a large remote database with relatively quick response time. A compiler program analyzes a given script to determine what data is needed by the current script and what potential scripts might be addressed from the current script and what server-stored data those scripts would need. That data is pre-fetched from the server upon commands from the compiler program in order to be quickly available for display at the client machine if requested by a user.

Abstract: A single frame buffer system is provided for displaying pixels of differing types according to standard pixel information types. Memory receives the pixel information wherein the pixel associated with each item of pixel information is further associated with a control signal for indicating the pixel type of the associated pixel. Devices for interpreting each type of pixel information to provide pixel display information are provided. Based upon the pixel type control signal, the associated pixel information is interpreted by the correct interpretation device to provide the pixel display information. The different pixel types may be graphics pixels and video pixels. In this case the output of either graphics processing circuitry or the output of video processing circuitry is selected for display according to the control signal. This single frame buffer system is effective to provide one-to-one mapping between the received pixel information and displayed pixels.

Abstract: A printer for printing an image onto a physical medium. The printer includes a print engine for physically printing the image onto the physical medium. The print engine receives signals representing the image to be printed directly from an external computer. The printer is coupleable to the external computer by a high-speed serial bus that enables the printer to print the images without prior interim storage of the signals in an on-board buffer in the printer. The signals may be processed by a processor in the external computer before being transmitted to the print engine, thereby eliminating a need for an on-board processor in the printer.

Abstract: One or more dynamically updated measures are generated for an audio stream. Processing is performed using the measures to distinguish silent periods from non-silent periods in the audio stream and the audio stream is encoded, wherein the silent periods are encoded differently from the non-silent periods. The processing is re-initialized during the encoding of the audio stream, if certain conditions are met. In a preferred embodiment, the processing is re-initialized if either of the following two conditions is met: (1) one of the non-silent periods is longer than a duration threshold or (2) an energy measure for the silent periods of the audio stream exceeds an energy threshold level.

Abstract: A corona detector for detecting a corona associated with a remote object. In one embodiment, the corona detector employs an optical filter having at least one passband centered at a wavelength corresponding with one of the molecular nitrogen emission spectrum second positive emission lines for filtering light from the remote object. A lens operatively coupled to the optical filter forms an image of the remote object, the lens having high transmissivity in the ultraviolet spectrum.

Abstract: A method, means, and computer program are provided for filtering jitter from motion estimation video data. The movement of one or more identifying features of an image is observed over a plurality of frames. The movement is analyzed and a pattern to the movement is determined. The pattern is analyzed for a jitter signature. In the event the pattern reflects the presence of jitter, the data associated with the affected frames of video is filtered by, for example, altering the magnitude of motion vectors to offset the components of jitter or discarding affected motion vectors. Embodiments of the invention filter translational jitter in either or both of the x- and y-axes as well as rotational jitter from motion estimation data. In one embodiment of the invention, motion vectors themselves are analyzed for the presence of jitter. In the event jitter is identified, affected motion vectors are discarded or filtered.

Abstract: Association of a physical driver object with its logical contents in a logical driver object by identifying the logical driver object and using a non-operating system component to cause recreation of the physical driver object. A handle and a memory address of a logical driver object are obtained and the handle is locked to prevent its movement in memory. A clone of the logical driver object is created, whereupon the contents of the logical driver object and the contents of the clone are swapped. The clone is then deleted. Subsequent reselection of the logical driver object into a device context results in an observable recreation of a corresponding physical driver object.
