  • Publication number: 20030035480
    Abstract: In a Fine Granular Video encoding system, a method for determining the number of transmission bits of SNR encoded and temporally encoded video data within a frame to balance image quality and object motion is presented. In accordance with the principles of the invention, a number of transmission bits at a known bit-rate for a quality enhanced video frame and a temporal enhanced video frame is determined to balance image quality and object motion smoothness. In one aspect of the invention, the number of bits transmitted in each frame is determined by comparing a ratio of a measure of video encoded information within the quality enhanced video frame and a measure of video encode information within the quality enhanced video frame and the temporally enhanced video frame to a known threshold level. The number of transmission bits in each enhancement layer is then determined using a first method when the ratio is above a known threshold and using a second method otherwise.

  • Publication number: 20030025665
    Abstract: Row addressing circuitry for implementing random row selection, pre-writes, and bi-directional scrolling includes a plurality of decoders, each connected to an address bus, each having a decoder enable input, and each producing row enable signals for rows of a pixel array. Row enable information for each row from each decoder is logically combined together to produce composite row drive information. Beneficially, each decoder is connected to the same address bus, and each decoder enable signal is produced from a common controller. By using the row enable signals, in synchronization with address information on the address bus, the correct row drive information, such as pre-writes or image information, is applied to each of pixels. Bi-directional scrolling can be implemented by enabling two rows to accept the same image information.

  • Publication number: 20030021343
    Abstract: The invention provides for a method and apparatus for encoding areas of an image that have definable parameters as graphic objects and then encoding the remaining areas of the image, if any, as a raster scanned image. The invention is particularly well suited for the encoding of an image that has areas that can be described as having a particular texture characteristic. Each area of the image, and subsequent images, that have the particular texture characteristic is encoded with an identifier to the texture characteristic, rather than encoded with the details of the texture itself. Regular texture pattern types, such as bricks, marble, woodgrain, satin, velour, etc. are associated with areas of the image, and the encoding of these areas merely contain an identification of the pattern type. Areas of the image that do not contain regular texture pattern types are encoded as conventional raster scanned areas of the image.

  • Publication number: 20020195971
    Abstract: An inverter circuit for a gas discharge lamp having a primary circuit having a DC voltage supply, a transformer, a switching circuit including a first switch and a second switch for controlling a conduction state of the inverter circuit; a tank circuit having a resonant inductor and a resonant capacitor, the lamp load being coupled with the resonant capacitor; and a capacitor coupled to the first and second switches for maintaining a voltage across a primary winding of said transformer. Accordingly, the required turns ratio of the transformer is reduced by half which reduces the power loss in the transformer, thereby improving circuit efficiency. In addition, energy stored in a leakage inductance, which is otherwise dissipated across the switches of the push-pull switch configuration in the prior art, is recovered or captured by the clamping capacitor, thereby preventing the occurrence of voltage spikes across the switches.

  • Publication number: 20020185993
    Abstract: A circuit for clamping a voltage across a switching element to a value equal to or less than the sum of the input voltage plus the voltage across a clamping capacitor is provided. The circuit achieves voltage clamping in a circuit configuration in which an active clamp circuit includes a switch and a clamping capacitor connected in parallel with a first winding of a coupled winding. The active clamp prevents the occurrence of voltage spikes across a first switching element. The clamping capacitor serves a second function in that it recovers energy stored in the first winding of the coupled winding.

  • Publication number: 20020159640
    Abstract: Multimedia information retrieval is performed using meta-descriptors in addition to descriptors. A “descriptor” is a representation of a feature, a “feature” being a distinctive characteristic of multimedia information, while a “meta-descriptor” is information about the descriptor. Meta-descriptors are generated for multimedia information in a repository (10, 12, 14, 16, 18, 20, 22, 24) by extracting the descriptors from the multimedia information (111), clustering the multimedia information based on the descriptors (112), assigning meta-descriptors to each cluster (113), and attaching the meta-descriptors to the multimedia information in the repository (114).

  • Publication number: 20020161809
    Abstract: Data compressed according to a lossy DCT-based algorithm, such as the MPEG or MPEG2 algorithms, is decompressed according to a dynamically-selected set of DCT coefficients, with unused coefficients masked out. A macroblock of the data exhibiting little motion is decompressed with a small subset of DCT coefficients, while a macroblock exhibiting more motion is decompressed using a larger subset of DCT coefficients up the full set of DCT coefficients. Average computational complexity is thus kept low, enabling the use of inexpensive equipment, while degradation is minimized.

  • Publication number: 20020148455
    Abstract: A ball-throwing machine includes a camera connected to a computer vision unit and a microphone connected to a speech-processing unit. The computer vision unit processes images from the camera to determine a user's position, and to detect user gestures from a predetermined repertoire of gestures. The speech-processing unit recognizes user vocal commands from a predetermined repertoire of commands. A computer receives information from a control panel, from the computer vision unit, from the speech-processing unit, and from a file describing the ballistic properties of the ball to be thrown. The computer accordingly determines a ball trajectory according to the user's position and parameters indicated by a combination of control-panel settings, user gestures, and user vocal commands. The computer then adjusts the direction, elevation, ball speed, and ball spin to conform to the determined trajectory, and initiates throwing of a ball accordingly.

The node topology is based on a computer system comprised of a high performance serial bus and a plurality of nodes coupled to the serial bus. Each node further includes an identification packet that is utilized for self-identifying itself on a network. In particular, a plurality of self-ID packets associated with the hardware actually present on the bus as well as a plurality of virtual nodes that are not actually present are generated during a self-ID process. Then, these self-ID packets are forwarded over the serial bus to identify themselves to other remaining nodes in the network. Thereafter, a topology mapping table from all of the self-ID packets is generated.
