摘要： In order to enable a data signal, such as an audio or video signal, to be marked with multiple watermarks a set of different codes or keys is used within a given application field. The set of codes/keys is known to a watermark embedder (20) and a watermark detector (22). In each watermark embedding step, whether it is a first embedding step or a subsequent embedding step, a different key is used. The embedder (22) includes a data extractor (24) for determining which key or keys has or have been used previously. A data generator (26) then selects a new key from the set of known keys.

摘要： A method of regulating sharing of a multimedia object (200) by a device (100), comprising registering usage information for the multimedia object (200) upon sharing of the multimedia object (200), and after the registering, billing a user of the device (100) for a certain amount in accordance with the registered usage information for the multimedia object (200). Registration preferably takes place in a client (101) arranged for sharing of the multimedia object (200). The usage information could for instance comprise the number of times a multimedia object has been shared, or the duration of the object. If a sufficient number of objects have been shared, or if the total time exceeds a maximum, the client (101) reports the usage information to a third party (130) for billing purposes.

摘要： A digital signal processor such as a watermark detector (12-18) operating with integer arithmetic circuits has a certain accuracy. Each processing step (multiplication, addition) increases the number of bits (the word length). For example, the Fast Fourier Transform (12) having a butterfly structure requires a plurality of such processing steps to be performed. In practical implementations, the processing steps are recursively performed by a single integer arithmetic circuit having a given word length, say N. After each step, the word length of the signal is reduced to the given word length N by rounding, truncation, or some other smart form of quantization. In order to prevent quantization errors, the signal is pre-processed by a pre-processor (19) which reduces the word length and which is invariant with respect to the subsequent process. This means that if the pre-processor operated with infinite accuracy, it would have no effect on the subsequent process. If such a pre-processor operates with finite accuracy, it will reduce the quantization noise.

摘要： A video watermarking scheme is disclosed, which is designed for the digital cinema format, as it will be used on large projector screens in theaters. The watermark is designed in such a way that it has minimal impact on the video quality, but is still detectable after capture with a handheld camera and conversion to, for instance, VHS, CD-Video or DVD format. The proposed watermarking system only exploits the temporal axis. This makes it invulnerable to geometrical distortions generally caused by such a way of capturing. The watermark is embedded by modulating a global property of the frames (e.g. the mean luminance) in accordance with the samples of the watermark. The embedding depth is preferably locally adapted within each frame to local statistics of the respective image. Watermark detection is performed by correlating the watermark sequence with extracted mean luminance values of a sequence of frames.
摘要翻译：公开了一种视频水印方案，其被设计用于数字电影格式，因为它将被用于剧院的大型投影仪屏幕上。水印的设计方式使其对视频质量的影响最小，但在使用手持相机拍摄并转换为例如VHS，CD-Video或DVD格式后，仍然可以检测到水印。所提出的水印系统仅利用时间轴。这使得它几何失真通常是由这种捕获方式造成的。通过根据水印的样本调制帧的全局属性（例如平均亮度）来嵌入水印。嵌入深度优选地在每个帧内局部地适应于相应图像的局部统计。通过将水印序列与帧序列的提取的平均亮度值相关联来执行水印检测。

摘要： Watermark-detection in the graphics card of a personal computer, for the purpose of copy-protection, has recently started to draw a lot of attention in standardization. Detection in the graphics card has problems completely different from the formerly considered detection in the DVD-drive, having to do with high data-rates, large scale-ranges and presence of multiple video-streams in the display area. This invention proposes conversion (32) of the computer's RGB output into a luminance signal (Y) prior to watermark detection by a conventional watermark detector (31) being arranged to detect the watermark in a such a luminance signal. The resolution of the monitor image to be inspected is preferably converted (33) to the conventional TV resolution of the (MPEG2-compressed) contents being played back on the computer's DVD drive. In graphic cards providing multiple outputs (VGA, TV, DVI), the same watermark detector may be time-sequentiall connected (34) to each of the outputs.
