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： Systems and methods of measuring a temporal offset between audio content and video content that employ audio fingerprints from an audio signal in the audio content, and video fingerprints from video frames in the video content. The systems obtain reference audio and video fingerprints prior to transmission of video over a media channel, and obtain target audio and video fingerprints subsequent to transmission of the video over the media channel. Each fingerprint has an associated time stamp. Using the reference and target audio fingerprints and their associated time stamps, the systems determine an audio time stamp offset. Using the reference and target video fingerprints and their associated time stamps, the systems determine a video time stamp offset. Using the audio and video time stamp offsets, the systems determine a temporal offset between the video content and the audio content introduced by the media channel.

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 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。
