Abstract: Client terminals report an easy-to-calculate identifier such as the Internet URL or a cryptographic hash of the content to a server. The server collects and counts the reported identifiers so as to obtain preliminary statistics. By aggregating these reported identifiers into the preliminary statistics, identifiers are revealed that are likely popular content. The server selects one or more identifiers from the preliminary statistics and makes these available to at least a subset of clients. The clients that obtain these one or more identifiers then access content and compute the easy-to-calculate identifiers as usual. If the computed identifier matches one of the identifiers obtained from the server, the client will additionally extract a watermarked identifier or compute a digital fingerprint of the content in question and report this to the server. The server then uses the received identifier or fingerprint to create final statistics by aggregating the preliminary statistics.

Abstract translation: 客户终端向服务器报告易于计算的标识符，例如Internet URL或内容的加密散列。 服务器收集并计算报告的标识符，以获取初步统计信息。 通过将这些报告的标识符聚合到初步统计信息中，显示可能是受欢迎的内容的标识符。 服务器从初步统计信息中选择一个或多个标识符，并使这些标识符可用于至少一个客户端子集。 获得这些一个或多个标识符的客户端然后访问内容并像往常一样计算易于计算的标识符。 如果计算出的标识符匹配从服务器获得的一个标识符，客户端将另外提取水印标识符或计算所讨论内容的数字指纹，并将其报告给服务器。 然后，服务器使用接收到的标识符或指纹，通过汇总初步统计信息来创建最终统计信息。

Abstract: 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.

Abstract: Advanced watermark embedders use psycho visual/acoustic models to minimize perception of the embedded watermark in media contents. However, it is expensive to implement such advanced watermark embedders in consumer appliances (3) such as DVD recorders. In accordance with the invention, embedding strength parameters (JND) are calculated (13) off-line at a remote location (1) and transmitted along with the media contents to the consumer appliance (3). A relatively simple embedder (33) uses the received parameters to control the strength of the watermark (36) to be embedded. The parameters may be accommodated in the transmitted signal as payload of a fragile watermark or as user data in an encrypted MPEG stream.

Abstract: Methods and arrangements are disclosed for embedding and detecting a watermark in a cinema movie, such that the watermark can be detected in a copy made by a handheld video camera. The watermark embedder divides each image frame into two areas. A watermark bit ‘+1’ is embedded in a frame by increasing the luminance of the first part and decreasing the luminance of the second part. A watermark bit ‘−1’ is embedded by decreasing the luminance of the first part and increasing the luminance of the second part. It is achieved with the invention that the embedded watermark survives ‘de-flicker’ operations that are often used to remove flicker caused by the different frame rates of cinema projection equipment and consumer camcorders.

Abstract: The problem is solved by a method for broadcasting a broadcast signal, comprising generating an information signal having in time a first content up to a certain time and a second content after this time. The information signal is broadcast as a broadcast signal via a first communication link At least one first feature is being provided with respect to the second content, for example an advertisement. The second content is detected in the information signal using the at least one first feature. On detection of the second content in the information signal at least one second feature is extracted from the first content in the information signal preceding the second content. The at least one second feature is sent to a user device using a second communication link, different from the first communication link, the second communication link being faster than the first communication link
