摘要： A method and arrangement for detecting a watermark in an information signal is disclosed. The method comprises the steps of computing (24-28, 30) the correlation (dk) of said watermark (Wi) and said information signal (e.g. an image Q) for a plurality of positions (k) of said watermark with respect to said information signal, and detecting (29) whether at least one of the respective correlation values exceeds a given threshold. The step of detecting (29) comprises determining the standard deviation ( sigma d) of the respective correlation values (dk), and setting the threshold to a given multiple (T) of said standard deviation. The multiple (T) is derived from a desired false alarm rate (watermark detected when there is none, or no watermark detected when there is one).

摘要： A digital media recorder and a method of controlling such is shown. During attempts to copy media content such as audio or a video sequences, sub-sequences are extracted from an input media sequence. A digital fingerprint of the sub-sequence is calculated and compared with at least one first reference fingerprint from a database. The outcome of the comparison determines the action to take in the further processing. Recording of the input media sequence on the media carrier is either allowed or obstructed, e.g. disallowed. In the case recording of the sequence is allowed, the database is updated with information that the digital media sequence has been recorded. This has the effect of a "speed bump," which limits the rate at which those copies of media content can be made, i.e. the effect is that of prohibiting more than a given number of copies within a given time frame.
摘要翻译：示出了数字媒体记录器及其控制方法。在尝试复制诸如音频或视频序列的媒体内容期间，从输入媒体序列中提取子序列。计算子序列的数字指纹并将其与来自数据库的至少一个第一参考指纹进行比较。比较的结果决定了在进一步处理中采取的行动。在媒体载体上记录输入媒体序列可以被允许或阻碍，例如，不允许。在允许记录序列的情况下，数据库用数字媒体序列已被记录的信息更新。这具有“减速块”的效果，其限制了可以制作这些媒体内容副本的速率，即效果是在给定的时间范围内禁止超过给定数量的副本。
