  • Publication number: 20210297690
    Abstract: A system and method for compressing video is disclosed, in which video frames that are only between consecutive I-frames are grouped into a video data set. The video data set is split into separate homogeneous files, and each of the homogeneous files are individually compressed. In one embodiment, the individually compressed files are multiplexed to form a bit stream.

  • Publication number: 20050008240
    Abstract: A drift-free hybrid method of performing video stitching is provided. The method includes decoding a plurality of video bitstreams and storing prediction information. The decoded bitstreams form video images, spatially composed into a combined image. The image comprises frames of ideal stitched video sequence. The method uses prediction information in conjunction with previously generated frames to predict pixel blocks in the next frame. A stitched predicted block in the next frame is subtracted from a corresponding block in a corresponding frame to create a stitched raw residual block. The raw residual block is forward transformed, quantized, entropy encoded and added to the stitched video bitstream along with the prediction information. Also, the stitched raw residual block is inverse transformed and dequantized to create a stitched decoded residual block. The residual block is added to the predicted block to generate the stitched reconstructed block in the next frame of the sequence.

  • Patent number: 6492917
    Abstract: An improved system and method for performing lossless data compression of a data string by parsing the data string and representing the parsed characters of the data string as irreducible grammar that is efficiently updatable. The system and method are each capable of parsing the data string into a least one variable of irreducible grammar, such that each variable represents a respective plurality of data characters of the data string, and formatting each variable of irreducible grammar as a linked list data structure having at least one pointer pointing to a linked list data structure representing another variable. The system and method are each further capable of updating the irreducible grammar based on at least one character to be parsed in the input string by changing at least one pointer of at least one of the linked list data structures to point to a linked list data structure different than that to which the at least one pointer pointed prior to updating.

  • Patent number: 6400289
    Abstract: A system and method employing an improved data compression and decompression technique for use in a communication system Specifically, the system and method employs an improved YK algorithm which uses an appropriate form of the trie data structure for the parsing operation. With the use of this data structure, the parsing complexity using this data structure is essentially proportional to the data size, and hence is very fast. The improved YK algorithm also is capable of handling errors in data without getting into an ambiguous state or causing the hardware or software system to crash. Furthermore, the improved YK algorithm is also capable of parsing the data based on predefined frequency characteristics and predefined grammar. The improved YK algorithm also sequentially updates the grammar, while keeping the number of variables below a pre-defined limit. This changes the grammar gradually, and can potentially increase the compression efficiency.
