  • Video deblocking filter
    Patent number: 7167522
    Abstract: Decomposition of deblocking filters used in block-based video compression allows reduction of computational redundancies.
    Type: Grant
    Filed: February 27, 2003
    Date of Patent: January 23, 2007
    Assignee: Texas Instruments Incorporated
    Inventor: Jennifer Webb
  • Error concealment and scene change detection
    Publication number: 20060251177
    Abstract: A concealment method for a lost frame in decoding a video sequence which was compressed with block motion compensation and transform coefficient quantization compares high-frequency content of co-located macroblocks of frames immediately preceding and following a lost frame to decide whether a scene change has occurred and what concealment approach to pursue.
    Type: Application
    Filed: May 9, 2005
    Publication date: November 9, 2006
    Inventor: Jennifer Webb
  • Video coding rate control
    Publication number: 20060056508
    Abstract: Video encoding (such as H.263, MPEG4, H.264) modifies TMN5-type frame skipping and quantization parameter updates according to buffer fullness levels and makes I-frame initial quantization parameters depend upon prior P-frame quantization parameters.
    Type: Application
    Filed: September 1, 2005
    Publication date: March 16, 2006
    Inventors: Phillippe Lafon, Jennifer Webb
  • Video error detection, recovery, and concealment
    Publication number: 20060013318
    Abstract: Decoding for H.264 with error detection, recovery, and concealment including two parsing functions for efficient detection of errors in exp-Golomb codewords, recovery for error in the number of reference frames, skipping to an uncorrupted SPS/PPS NAL unit, and concealment of invalid gaps in frame number by separate gap size 2 and greater than size 2 analysis.
    Type: Application
    Filed: June 22, 2005
    Publication date: January 19, 2006

  • Video coding rate control
    Publication number: 20050036544
    Abstract: The quantizer parameter for video encoding of the H.263 or MPEG-4 type updates in response to buffer discrepancy adapts to the targeted number of bits per frame, and saturates the maximum change of the quantizer parameter.
