摘要： 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.

摘要： A method comprises accessing encoded video data; accessing a list of watermarks to the encoded video data; determining syntax elements for current blocks of video data and syntax elements of currents blocks with the watermarks; removing watermarks that cause visible artifacts based on differences in the syntax elements between the current blocks and current blocks with watermarks, thereby creating filtered list of acceptable watermarks. The method can further include determining coding variable ranges for the current block and current block with watermarks from the list; comparing the coding variable ranges for the current blocks and current blocks with watermarks from the list; and filtering out watermarks that yield coding variable ranges outside the coding variable ranges of the current blocks. Additionally, the method can include determining bit lengths of the current blocks and current blocks with watermarks from the list; comparing bit lengths of the current blocks and current blocks with watermarks from the list; and filtering out watermarks that yield bit lengths not equal to the bit lengths of the current blocks.

摘要： Implementations may relate to various aspects of modifying, or using, a coded bitstream, or to recovering water-marking 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. Particular implementations recover watermarking information using detection data and feature information.

摘要： 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.

摘要： Information available at a decoder is embedded into image content after decoding by first representing that information by at least one film grain pattern and then blending that at least one film grain pattern with the decoded image content. Such image content is typically in the form of a movie and examples of the information to be embedded include identification of the specific decoding device, the user of the decoding device, the time and date of decoding, the model number of the device, the versions of software running on the device, the status of the device or connections to the device, the contents of device registers or memory locations within the device, among many other possible data. When an unauthorized copy of image content is discovered, the copied image content undergoes a comparison to the decoded image content to generate difference data. Thereafter, the difference data undergoes comparison with a database of film grain patterns to recover the embedded data.
