摘要： A method comprises accessing changes which can be watermarks in a list for coded data, the changes having an syntax element, an original value and an candidate alternative value; determining for a subset a group of compliant changes from the changes, the complaint changes being compliant with a coding protocol such as a CABAC encoding protocol; and selecting for the subset only compliant changes that result in the subset having only one candidate alternative value for each syntax elements and result in only compliant changes also meeting at least one performance criterion. The method can include determining fidelity, recoverability, or robustness of the watermarks and removing or preventing watermarks from being in the subset based on the fidelity, recoverability, or robustness, wherein fidelity, recoverability, and robustness are performance criteria. The method can include determining at least two performance values for the watermarks, determining some collective metric of the at least two performance values, and removing or preventing watermarks from being in the subset based on the same collective metric.

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.

摘要： A low-frequency, temporally asymmetric watermark carrier monotonically decreases in luminance more slowly than it monotonically increases in luminance. This allows the carrier to be embedded, e.g., in a video work, in a manner that renders the resultant watermark virtually invisible to the human eye. Moreover, the resultant watermark is substantially resistant to common pirating techniques in which high-frequency visual content (e.g., including watermark data) tends to be filtered out by piracy processing.

摘要： A method comprises receiving original encoded video stream as one input, accessing encoded data divided into slices which are further divided into blocks, receiving the list of possible changes or watermarks as another input, accessing at least one block, decoding each slice, setting down each slice, extracting from the list those changes that apply to the at least one block, and constructing propagation maps from inter-prediction or intra-prediction using changes for the at least one block. The method can further comprise decoding luminance data using the propagation maps, comparing the luminance data to a fidelity threshold, and applying possible changes or watermarks to those not exceeding the fidelity threshold.

摘要： 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. Particular implementations recover watermarking information using detection data and feature information.
摘要翻译：实现可以涉及修改或使用编码比特流的各个方面，或者从数据恢复水印信息。在一个实现中，编码比特流被修改为允许将水印应用于编码比特流，而不改变比特流中任何其他语法元素的编码。这是通过识别改变编码语法元素所必需的条件而不中断后续编码元素的解释来执行的。如果修改后的值产生与原始值相同的解码变量，则将编码语法元素替换为其他编码值。特定实现集中于使用熵编码编码的语法元素，包括例如基于上下文的自适应二进制算术编码（CABAC）。不管编码或水印的类型如何，各种实现可以提供恢复水印信息。具体实现使用检测数据和特征信息恢复水印信息。
