Patent number: 10014977Abstract: A system and method for transmitting data over a channel, in which the data are categorized in at least two different categories. For example, the data are categorized according to the effect on perceived degradation on the data when error mitigation is performed on the data. Corrupted data of the first category are replaced using a first replacement method, such as retransmission and forward error correction. The corrupted data of the second category are replaced using a second replacement method different from the first replacement method, e.g., error mitigation or interpolation.Type: GrantFiled: September 21, 2015Date of Patent: July 3, 2018Assignee: AT&T Intellectual Property II, L.P.Inventors: Peter Frank Driessen, Mathias R. Kretschmer, Schuyler Reynier Quackenbush, James H. Snyder

Publication number: 20120033812Abstract: An apparatus for compressing media content is disclosed. The apparatus divides the media content into at least three predetermined portions, compresses each of the at least three portions using one of at least three different compression algorithms and makes the at least three compressed predetermined portions publicly available. Making the portions publicly available includes, for example, transmitting the portions over a computer network such as the Internet.Type: ApplicationFiled: October 17, 2011Publication date: February 9, 2012Applicant: AT&T Intellectual Property II, L.P.Inventors: John Blakeway Lacy, Schuyler Reynier Quackenbush, James H.

Patent number: 8095794Abstract: A system and method of generating a watermarked signal are disclosed. The system segments the signal into overlapping blocks using a window function and processes the overlapping blocks according to whether each block is odd- or even-numbered. The system windows the odd-numbered blocks, modulates the phase of each block in the frequency domain, transforms each modulated block in the time domain, windows each block transformed into the time domain and overlap-adds each odd-numbered block with each even-numbered block to generate the watermarked signal.Type: GrantFiled: November 12, 2008Date of Patent: January 10, 2012Assignee: AT&T Intellectual Property II, L.P.Inventors: James David Johnston, Shyh-Shiaw Kuo, Schuyler Reynier Quackenbush, William Turin

Patent number: 7882357Abstract: A system, method and computer readable medium that processing a watermarked signal using the phase Sk(f) of an original signal. The watermarked signal includes odd and even overlapped blocks where the watermark is contained in the even blocks. The method comprises test-decoding the watermarked signal and, if the watermarked signal contains errors, recoding the watermarked signal with a higher redundancy code. The steps of test-decoding and recording may be performed until all errors are corrected.Type: GrantFiled: April 4, 2006Date of Patent: February 1, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: James David Johnston, Shyh-Shiaw Kuo, Schuyler Reynier Quackenbush, William Turin

Patent number: 7802101Abstract: A system and method of retrieving a watermark in a watermarked signal are disclosed. The watermarked signal comprises odd and even overlapped blocks where the watermark is contained in the even blocks. The method comprises, for each k-th even block, subtracting the two adjacent odd numbered blocks from the k-th even block of the watermarked signal to retrieve s *k(n), transforming s *k(n) into the frequency domain to generate S k(f), calculating a phase of S k(f) as ? (f) and a phase of Sk(f) as ?(f), calculating the difference ? (f) between ? (f) and ?(f), unwrapping ? (f) to obtain the phase modulation {tilde over (?)} k(f), and using a Viterbi search to retrieve the watermark embedded in {tilde over (?)} k(f).Type: GrantFiled: March 30, 2009Date of Patent: September 21, 2010Assignee: AT&T Intellectual Property II, L.P.Inventors: James David Johnston, Shyh-Shiaw Kuo, Schuyler Reynier Quackenbush, William Turin

Patent number: 7725808Abstract: The present invention provides a system and method for storing re-synchronization, error correction and/or error detection data within an existing communication protocol, while still maintaining full compliances to a standard, such as the MPEG-2 AAC standard. By doing so, data information can still be passed from an encoder to a decoder via a channel using an existing and well known standard transport protocol. However, the existing well known transport protocol can now include the data necessary for synchronization of the decoder to the received raw data, along with error detection and error correction by the decoder.Type: GrantFiled: January 22, 2008Date of Patent: May 25, 2010Assignee: AT&T Intellectual Property II, LPInventors: James David Johnston, Schuyler Reynier Quackenbush
