Method And Apparatus For Audio Error Concealment Using Data Hiding

View page
US Patent:
7047187, May 16, 2006
Filed:
Feb 27, 2002
Appl. No.:
10/083886
Inventors:
Szeming Cheng - College Station TX, US
Hong Heather Yu - Princeton Jct. NJ, US
Zixiang Xiong - College Station TX, US
Assignee:
Matsushita Electric Industrial Co., Ltd. - Osaka
International Classification:
G10L 19/04
US Classification:
704219, 7042001, 704500
Abstract:
A method for concealing errors in an audio signal includes digitally encoding the audio signal into a plurality of audio data packets representative of the audio signal; determining a perceptually tolerable distortion limit for the audio packets; and altering a value of at least one audio packet by an amount within the perceptually tolerable distortion limit utilizing information representative of a different audio data packet.

Enhanced Method For Digital Data Hiding

US Patent:
7076659, Jul 11, 2006
Filed:
Feb 25, 2002
Appl. No.:
10/082551
Inventors:
Szeming Cheng - College Station TX, US
Hong Heather Yu - Princeton Jct. NJ, US
Zixiang Xiong - College Station TX, US
Assignee:
Matsushita Electric Industrial Co., Ltd. - Osaka
International Classification:
H04B 1/69
H04K 1/06
H04L 9/00
H04N 7/16
US Classification:
713176, 380 38, 380210, 382100
Abstract:
A method is provided for enhanced spread spectrum watermarking. The improved watermarking method includes: receiving host data which is expressed in a transform domain by a plurality of host transform parameters; reducing variance between the plurality of host transform parameters, thereby forming an enhanced sequence of host transform parameters; and adding a watermark to the enhanced sequence of host transform parameters using a spread spectrum technique. The enhanced sequence of host transform parameters may be formed by arranging the plurality of host transform parameters in at least one of an ascending order or descending order; determining a difference for each pair of consecutive host transform parameters; and alternating the sign of every other difference value, thereby forming the enhanced sequence of host transform parameters.

Data Encoding And Decoding Using Slepian-Wolf Coded Nested Quantization To Achieve Wyner-Ziv Coding

View page
US Patent:
7256716, Aug 14, 2007
Filed:
Mar 1, 2005
Appl. No.:
11/068737
Inventors:
Zhixin Liu - College Station TX, US
Samuel S. Cheng - Houston TX, US
Angelos D. Liveris - Stafford TX, US
Zixiang Xiong - Spring TX, US
Assignee:
The Texas A&M University System - College Station TX
International Classification:
H03M 7/34
US Classification:
341 51, 341 56, 341 67
Abstract:
A system and method for realizing a Wyner-Ziv encoder may involve the following steps: (a) applying nested quantization to input data from an information source in order to generate intermediate data; and (b) encoding the intermediate data using an asymmetric Slepian-Wolf encoder in order to generate compressed output data representing the input data. Similarly, a Wyner-Ziv decoder may be realized by applying an asymmetric Slepian-Wolf decoder to compressed input data (representing samples of a first source) to obtain intermediate values, and then, jointly decoding the intermediate values using side information (samples of a second source having known correlation with respect to the first source).

Packetization Of Fgs/Pfgs Video Bitstreams

View page
US Patent:
7283589, Oct 16, 2007
Filed:
Mar 10, 2003
Appl. No.:
10/385014
Inventors:
Hua Cai - Kowloon, HK
Guobin Shen - Beijing, CN
Zixiang Xiong - College Station TX, US
Shipeng Li - Irvine CA, US
Bing Zeng - Kowloon, HK
Assignee:
Microsoft Corporation - Redmond WA
International Classification:
H04N 7/12
US Classification:
37524026
Abstract:
A video encoding system performs packetization of FGS/PFGS encoded video bitstreams by selecting encoded bitstream segments for packetization based on an estimated total contribution to distortion reduction associated with each encoded bitstream segment. The selected bitstream segments are then packetized according to a packet-independence packetization strategy that minimizes inter-packet dependency.

Wyner-Ziv Coding Based On Tcq And Ldpc Codes

View page
US Patent:
7414549, Aug 19, 2008
Filed:
Aug 4, 2006
Appl. No.:
11/499601
Inventors:
Yang Yang - College Station TX, US
Zixiang Xiong - Spring TX, US
Assignee:
The Texas A&M University System - College Station TX
International Classification:
H03M 7/00
US Classification:
341 50, 341 87
Abstract:
An encoder employs a trellis coded quantization (TCQ) unit and a compression unit. The TCQ uses a set of polynomials that have been selected to maximize granular gain. The TCQ unit operates on a block of samples from a source. The compression unit compresses bit planes of the TCQ output, using parity check matrices of corresponding LDPC codes, to obtain corresponding syndromes. The parity check matrices are selected so their compression performance approaches close to the limit for Slepian-Wolf coding. A decoder employs a decoding unit and an estimation unit. The decoding unit decodes the syndromes using side information to produce an estimate for the TCQ output. The side information is correlated with the source. The estimation unit estimates the block of source samples using the estimated TCQ output and the side information. Trellis coded vector quantization may be used as an alternative to TCQ.
