  • Patent number: 6826245
    Abstract: Method and system for optimally estimating the location of each of a sequence of two or more synchronization patterns in a digital signal bit stream. A first reference location for a sync pattern is determined. A Boolean product or other product of the sync pattern (of length S) with S consecutive bit values of the digital stream is formed, for each of a selected consecutive sequence of candidates for a second reference location of the sync pattern within a window of selected length. A candidate reference location that yields the largest (or smallest) product value within the window is estimated to be a second or “next” reference location of the sync pattern, if the product value is at least equal to (or, alternatively, is no greater than) a selected threshold value. The sync pattern used for testing the digital stream can be varied from one location to another. The number of bit matches or the number of bit non-matches can be used to determine an optimal reference location for the sync pattern.

  • Patent number: 6807313
    Abstract: The present invention relates to a method of adaptively enhancing a digital image based on image content. An accurate determination of image type permits implementation of an image enhancement technique that is matched to the image type. The method is advantageous when the image type of the received images can vary. In one embodiment the method distinguishes between line art images and continuous tone images. The method includes application of a window to a pixels in a source array. The number of colors in each of the resulting windowed arrays is determined. Each color can optionally be defined as a range of colors. A color range total is calculated from the sum of the number of windowed arrays in one or more subsets of the plurality of possible numbers of colors. Image type is determined in response to the color range total and an enhancement process matched to the image type is applied to the digital image data.

  • Patent number: 6779149
    Abstract: Method and system for indicating that at least one row or column of a DVD data block has an uncorrectable number of errors, by marking or flagging the corrupted codewords of a codeword with defect detect signals. When a column (or row) of the data block is found to contain more than a thereshold number of errors, a selected number w of distinguishable codeword values (DSVs) “x” is associated with at least one column (or with at least one row) of the block. When the block is further processed and the presence of more than a threshold number of DSVs is sensed, the system interprets this occurrence as indicating that an uncorrectable group of errors has occurred in a column and/or row of the block.

  • Patent number: 6778187
    Abstract: Methods and devices for compressing and uncompressing three color component graphics and/or digital video data for storage to and retrieval from a reduced memory space, while allocating memory space for pixel data special attribute, such as a transparency attribute. 24 bit video data, for example, may be compressed and stored along with 2 bits of transparency data in a 16-bit memory space, without undue loss of fidelity relative to the original graphics and/or video data. The stored and compressed video data may be uncompressed and a correction factor may be selectively applied to each of the three component pixel data. The resulting uncompressed pixel data matches or closely resembles the video data prior to compression and storage. The correction factor may vary depending upon the color space of the graphics and/or video pixel data.

  • Patent number: 6771275
    Abstract: A signal conversion system parses a multi-dimensional input signal into most-significant and least-significant portions. The most-significant portions are used as an index to a look-up-table. Stored in each entry of the look-up-table is a base value and multi-dimensional differential values. The system generates an output representation of the signal by combining the corresponding base value with interpolated differences determined by interpolation performed using the differential values and the least-significant portions. Interpolation error is decreased by storing intermediate differential values. Output processing is used for linearization.

  • Patent number: 6725420
    Abstract: Method and system for compensating for a segment length of one or more of three consecutive mark and space segments utilized in a computer system. The three segments are received at a first pre-processor, the first segment is separated and issued separately from the remaining two segments, and the first segment length is compared with a permitted range of lengths. If the first segment length is not within the permitted range, a first error signal is issued, preferably indicating the non-complying first length. This process is repeated at second and third pre-processors. A segment processor receives the three individual segments and the error signals and non-complying lengths, if any, and compensates or corrects for any non-complying segment lengths before further processing occurs.

  • Patent number: 6708334
    Abstract: A navigation system for a digital versatile disc system includes multiple synchronized threads, each of which separately performs a single task so that several tasks can be performed concurrently. In one embodiment, a stream parser thread, a navigation thread and a user interface thread are always created when the DVD player begins operation. In addition, a highlight thread may also be created if the DVD data stream contains highlight information. The stream parser thread receives the DVD data stream and extracts navigation commands and DVD content data from the stream. The navigation commands are sent to the navigation thread for processing, but the content data is sent to system decoders for display. The navigation thread operates separately from the stream parser thread and processes the retrieved navigation commands to select portions of the DVD data stream for display.
