Abstract: The present invention combines a data processing structure with a graphical user interface (GUI) to create an information analysis tool wherein multiple functions are combined in a network to extract information from multiple data sources. The functional network is created, and graphically represented to the user, by linking individual operations together. The combination of individual operations is not limited by the input or output characteristic of any single operation. The form of the input to or output from any individual operation, whether from a database or from another operation, is the same. That is, both the input to and the output from an analysis function is a list of document identifiers and corresponding document characteristics. Because the form of the input and output from each operation is the same, arbitrary combinations of operations may be created. Moreover, functional networks of individual operations can then be used for database retrieval as well as to filter data streams. Furthermore, the user is able to create a visual representation of the structure forming a functional network which may be dynamically updated as new data is added or functions switched in or out. Because, inter alia, the network structure dynamically responds to information as it is presented to the network, the visual representation of the network conveniently provides the user with information concerning the characteristics of the database or stream of data that are substantially unavailable through conventional search, filtering, or clustering techniques alone.

Abstract: Disclosed herein is a system and method for reconstruction video information lost as a result of transmission errors. The system and method have four aspects, including: (1) changing the bit and/or packet rate; (2) inserting redundant information into the video bitstream; (3) providing automatic refresh of certain regions of the video on a periodic basis; and (4) interleaving coded macroblocks into diversity groups for transmission to spatially spread the effect of lost packets. The image reconstruction may then take advantage of these three aspects to provide an enhanced result in the presence of transmission losses.

Abstract: Described are techniques in video coding and/or decoding that allow for selectively breaking prediction and/or in loop filtering across segment boundaries between different segments of a video picture. A high layer syntax element, such as a parameter set or a slice header, may contain one or more indications signalling to an encoder and/or decoder whether an associated prediction or loop filtering tool may be applied across the segment boundary. In response to such one or more indications, the encoder and/or decoder may then control the prediction or loop filtering tool accordingly.

Abstract: The present invention provides a system and method for detecting macroblocks of a video frame that are located in one or more motion wake regions of the video frame. In one embodiment, a motion wake engine is configured to select a subset of macroblocks comprising non-peripherally located macroblocks selected to be inter-coded with motion vector magnitudes less than a predetermined motion vector threshold. Then, the motion wake engine identifies which macroblocks of the subset of macroblocks are located in first, second, third, or fourth motion wake regions of the video frame based upon a motion vector analysis of nearest neighbor macroblocks. In another embodiment of the invention, the motion wake engine applies error concealment/video improvement techniques to the identified macroblocks for video error concealment and for reducing visual artifacts associated with the motion wake regions.

Abstract: A method for reducing or eliminating coding artifacts in video pictures processed using intra block prediction methods, for example, according to the H.264 standard. The causes of the coding artifacts are identified to be the intra prediction modes with prediction directions that are not in the direction of the raster scan. Filtering the affected blocks with a simple one-dimensional spatial filter will reduce or even eliminate these coding artifacts.

Abstract: The present invention provides, in one embodiment, a system and method for concealing video errors. The system encodes, reorders, and packetizes video information into video data packets for transmission over a communication network such that the system conceals errors caused by lost video data packets when the system receives, depacketizes, orders, and decodes the data packets. In one embodiment, the system and method encodes and packetizes video information, such that adjacent macroblocks are not placed in the same video data packets. Additionally, the system and method may provide information accompanying the video data packets to facilitate the decoding process. An advantage to such a scheme is that errors due to video data packet loss are spatially distributed over a video frame. Thus, if regions of data surrounding a lost macroblock are successfully decoded, the decoder may predict motion vectors and spatial content with a higher degree of accuracy, which leads to higher video quality.

Abstract: The present invention allows video images with improved subjective quality to be transmitted without a concomitant increase in a total number of bits transmitted per frame. Quantization parameters are applied to coefficients of macroblocks within a given video frame. A lower value of quantization parameter is applied near a central region of a video frame. This central region is referred to as a prime video region. Applying a lower quantization parameter to the prime video region has the effect of increasing the bit density within that area thereby improving the video quality. Outside of the prime video region, the bit density is progressively decreased on a macroblock-by-macroblock basis so as to have a zero or near-zero net-gain in bit density over the entire video frame.

Abstract: Disclosed herein in one embodiment is an adaptive coding threshold algorithm for a videoconference system which alleviates problems due to the erroneous recoding of stationary areas of images caused by image noise. The algorithm, which is preferably implementable on a videoconference encoder, assesses the coding parameters for a current macroblock and the coding parameters for that same macroblock the last time it was coded. If for both macroblocks the coding was non-intra, with a [0,0] motion vector, and with a low quantization parameter, a determination is made that the current macroblock depicts a stationary image. Accordingly, the algorithm increases the coding threshold (T1) for the blocks within that macroblock, so that it becomes more difficult for those particular blocks to be recoded. This renders the block with stationary content less susceptible to erroneous recoding, while preserving system bandwidth and improving image quality. Additionally, related noise assessment techniques can be employed at the encoder or decoder without the adjustment of the coding threshold T1.
