Patent number: 8358703Abstract: Implementations may relate to various aspects of modifying, or using, a coded bitstream, or to recovering watermarking information from data. In one implementation, a coded bitstream is modified to allow for the application of a watermark to the coded bitstream without changing the coding of any other syntax elements in the bitstream. This is performed by identifying conditions necessary to change a coded syntax element without disrupting the interpretation of subsequent coded elements. The coded syntax element is replaced with another coded value if the modified value generates the same decoding variables as the original value would have generated. Particular implementations focus on syntax elements coded using entropy coding, including, for example, Context-based Adaptive Binary Arithmetic Coding (CABAC). Regardless of the type of coding or watermarking, various implementations may provide for recovering watermarking information.Type: GrantFiled: November 2, 2007Date of Patent: January 22, 2013Assignee: Thomson LicensingInventors: Dekun Zou, Jeffrey Adam Bloom, Peng Yin, Oscar Divorra Escoda

Patent number: 8352810Abstract: Detection of faults in a transmitted signal stream occurs by recovering, from the information stream, a water mark embedded in the stream prior to transmission. The embedded watermark has data characteristic of stream quality. Thereafter, the at least one watermark property is analyzed to detect faults in the received information stream.Type: GrantFiled: May 6, 2008Date of Patent: January 8, 2013Assignee: Thomson LicensingInventors: Are Olafsen, Jeffrey Adam Bloom, Kumar Ramaswamy

Patent number: 8331609Abstract: Embodiments of the present invention provide a method, apparatus and system for temporal synchronization of digital content based on a marker symbol and a marker code. A marker symbol is inserted at an identifiable location of a payload (e.g., the beginning and/or end of a payload) at regular intervals in the digital content and the payload is marker coded to form a periodic sequence. The payload is marker coded such that the maker symbol is not repeated by the coded payload. The periodic sequence is then embedded into digital content. A decoder is able to re-synchronize the payload by determining the location of the marker symbol. As such, a method, apparatus and system is provided for robust temporal synchronization for, for example, content encoding and decoding for applications such as audio and video water-marking and the like.Type: GrantFiled: December 8, 2006Date of Patent: December 11, 2012Assignee: Thomson LicensingInventors: Jun Tian, Jeffrey Adam Bloom

Publication number: 20120246672Abstract: An apparatus and method for encoding and decoding a broadcast data stream that includes encrypted advertisement cue messages. The encrypted advertisement cue message data representing a advertisement to be inserted into a stream and data representing an insertion time within said broadcast data stream that is associated with said advertisement. The advertisement cue messages are encrypted and encrypted using a encryption technique. The encrypted advertisement cue message masks the insertion time for the advertisement and prevents automatically skipping of the advertisement data.Type: ApplicationFiled: December 16, 2009Publication date: September 27, 2012Inventors: Avinash Sridhar, David Anthony Campana, Alan Jay Stein, Jeffrey Adam Bloom

Publication number: 20110222723Abstract: A method comprises providing a change to apply to video; dividing video into blocks; creating propagation map which captures only specific changes to blocks that would be changed by the application of the change; evaluating the change based on a luminance criterion as being a perceptible change or an imperceptible change; for propagation maps of an imperceptible change, storing the propagation map to a list, wherein the propagation map is the principle data structure to be applied to the video. The propagation map can be created by using motion vector changes associated with the change.Type: ApplicationFiled: August 18, 2009Publication date: September 15, 2011Applicant: Thomson Licensing LLCInventors: Shan He, Jeffrey Adam Bloom, Dekun Zou

Publication number: 20110182466Abstract: A method and system of detecting colluders conducting a collusion attack including a minority-type collusion attack on a digital product includes the generation of codewords used as watermarks in the digital product. The inner code of the codewords is generated using permutations of rows in a Hadamard matrix and concatenating them together. A typical outer code of the codeword is the Reed Solomon code. An adaptive detector is able to accurately detect one of three or more colluders of a minority-type attack. Prior art schemes using an error correcting code-based watermarking mechanism with an inner code fail to detect colluders with a minority-type collusion attack which includes three colluders.Type: ApplicationFiled: September 26, 2008Publication date: July 28, 2011Inventors: Wan-Yi Lin, Shan He, Jeffrey Adam Bloom

Publication number: 20100150394Abstract: Various implementations are provided for, for example, determining watermarking data, performing the watermarking, and processing watermarked data. At least one implementation watermarks AVC bitstream that uses CAVLC entropy coding. The watermarking data may be determined in a pre-processing stage and stored for later use in watermark a bitstream. One method accesses variable-length encoded data including an encoding of information identifying an actual reference used to predictively encode an image. The encoding of the information has a particular value. The method determines an alternative value that is different from the particular value, such that the alternative value is an encoding of alternative information that identifies a different reference from the actual reference. The alternative value is for use in watermarking the variable-length encoded data.Type: ApplicationFiled: June 13, 2008Publication date: June 17, 2010Inventors: Jeffrey Adam Bloom, Dekun Zou
