  • Method And Apparatus For Arithmetic Coding

    view source
  • US Patent:
    6850175, Feb 1, 2005
  • Filed:
    Sep 18, 2003
  • Appl. No.:
    10/666687
  • Inventors:
    Frank Jan Bossen - San Jose CA,
  • Assignee:
    NTT Docomo, Inc. - Tokyo
  • International Classification:
    H03M 700
  • US Classification:
    341107, 341106
  • Abstract:
    Methods and apparatuses for performing arithmetic encoding and/or decoding are disclosed. In one embodiment, a method for encoding data comprises coding a plurality of events in an event sequence to produce encoded data and generating a bitstream using the encoded data, including adding zero or more stuffing bits to the bitstream after the encoded data. The zero or more stuffing bits operate to substantially maintain a relationship between an amount of events encoded, a number of blocks being coded, and a number of bits in the bitstream.

  • US Patent:
    2004005, Mar 25, 2004
  • Filed:
    Sep 18, 2003
  • Appl. No.:
    10/665638
  • Inventors:
    Frank Bossen - San Jose CA,
  • International Classification:
    G06K009/36
    H03M007/00
  • US Classification:
    341/106000
  • Abstract:
    Methods and apparatuses for performing arithmetic encoding and/or decoding are disclosed. In one embodiment, an arithmetic decoder comprises a sequencer to generate a context identifier for an event of an event sequence, a probability estimator to determine a value for a LPS and a probability estimate for the LPS, and a decoding engine that includes a range register to assign a value to a range for the LPS. The value is based on the probability estimate, a value stored in the range register and the context identifier to a range for the LPS if the context identifier is not equal to an index and the value is not based on the value stored in range register if the context identifier is equal to the index. The decoding engine further determines a value of a binary event based on the value of the range for the LPS and bits from an information sequence.
  • Low-Complexity Intra Prediction For Video Coding

  • US Patent:
    2013011, May 9, 2013
  • Filed:
    Jul 14, 2011
  • Appl. No.:
    13/809511
  • Inventors:
    Frank Jan Bossen - Mountain View CA,
    Thiow Keng Tan - Jalan Sindor,
  • Assignee:
    NTT DOCOMO, INC. - Chiyoda-ku, Tokyo
  • International Classification:
    H04N 7/26
  • US Classification:
    37524012
  • Abstract:
    The present invention provides a unique intra prediction process which improves the efficiency of video coding. H.264/AVC uses reference pixels in a horizontal boundary located immediately above a target block to be predicted and reference pixels in a vertical boundary located immediately left of the target block. In the present invention, at least some of one of an array of horizontal boundary pixels and an array of vertical boundary pixels are retrieved. Then, the retrieved pixels are added to the other boundary pixels to extend the array thereof. Intra prediction is performed, based solely on the extended array of boundary pixels.
  • Adaptive Binarization For Arithmetic Coding

  • US Patent:
    2013002, Jan 31, 2013
  • Filed:
    Apr 8, 2011
  • Appl. No.:
    13/638803
  • Inventors:
    Frank Jan Bossen - Mountain View CA,
  • Assignee:
    NTT DOCOMO, INC. - Chiyoda-ku, Tokyo
  • International Classification:
    H04N 7/26
    H03M 7/00
  • US Classification:
    37524025, 341107, 37524001, 375E07027
  • Abstract:
    The present invention first provides adaptive binarization in which a binarizer outputs binary symbol in length, which is variable adaptively to the probability of the source. When the probability is low, it is desirable to decrease the length of the binary symbols to improve the efficiency of arithmetic coding and reduce the complexity of coding calculation. On the other hand, when the probability is high, it is desirable to increase the length of the binary symbols to improve the overall process speed of a decoder. Specifically, a binarizer, according to the present invention, binarizes mapping unit values from a non-binary symbol into binary symbols. The number of binary symbols is inversely proportional to the size of the mapping unit value. In the present invention, the mapping unit value is made variable adaptively to the probability. Thus, the number of binary symbols from the binarizer is also variable adaptively to the probability parameter.

  • Filed:
    Jun 3, 2011
  • Appl. No.:
    13/153289
  • Inventors:
    Frank Jan Bossen - San Jose CA,
  • International Classification:
    H04N 7/32

  • US Classification:
    37524016, 375E07105, 375E07115
  • Abstract:
    Video compression algorithms typically represent visual information by a combination of motion and texture data. Motion data describes the temporal relationship between the content of a frame and that of a previous frame. This invention describes a method and apparatus for efficiently encoding motion data, particularly in the presence of horizontal and/or vertical motion boundaries.
