Abstract: In a method of distributing content in plural fragments, each fragment being no longer than a given maximum fragment length, a method of watermarking the content prior to fragmenting the content into the plural fragments, comprising watermarking a given payload symbol from a given alphabet in a given segment of the content, and treating a segment prior to or following the given segment as an intermediary segment, the length of this intermediary segment being substantially equal to or greater than the maximum fragment length.

Abstract: A device for rendering content from a first source comprising a first input for receving the content from the first source, a second input for receiving a substition content item from a second source, a substitution module for substituting a segment of the content with the substitution content item, and rendering means for rendering the content wherein the segment is substituted with the substitution content item. The rendering device has monitoring module for monitoring the reception of the segment, and controlling the substitution module dependent on whether the segment is being received, such that the substitution module ceases the substitution upon failure to receive the segment.

Abstract: A method of and system for distributing a content item, having a plurality of segments. A composite content item is created by concatenating segments from different content items from different agencies. A segment of the composite content item may or may not already comprise a previously embedded segment watermark carrying a previously embedded segment payload. The method comprises determining if the segment already comprises a previously embedded segment watermark, and if so, logging the previously embedded segment payload in a watermark transaction log associated with the new segment payload; otherwise, embedding the new segment payload as a watermark in the segment.In the case that the segment already comprises a previously embedded segment payload, the previously embedded payload is logged in a watermark transaction log, and the previously embedded segment payload is replaced with a new segment watermark that represents the new segment payload. A method and system for monitoring the distribution of a content item using a transaction log.

Abstract translation: 一种用于分发具有多个段的内容项的方法和系统。 通过连接来自不同机构的不同内容项的段来创建复合内容项。 复合内容项的片段可以包括或可以不包括携带先前嵌入的片段有效载荷的先前嵌入的片段水印。 该方法包括确定该段是否已经包括先前嵌入的段水印，如果是，则将先前嵌入的段有效载荷记录在与新的段有效载荷相关联的水印事务日志中; 否则，将新的段有效载荷作为水印嵌入到段中。在段已经包括先前嵌入的段有效载荷的情况下，先前嵌入的有效载荷被记录在水印事务日志中，并且先前嵌入的段有效载荷被替换为 新的段水印，代表新的段有效载荷。 一种用于使用事务日志监视内容项目的分发的方法和系统。

Abstract: A method of detecting a payload embedded using watermarking in a content stream, the payload being different in a first and a second segment of the content stream, a payload in the second segment having a predetermined relationship with a payload in the first segment, the method comprising selecting a point in the content stream where the first segment is likely to end and the second segment to begin, sampling the stream to obtain a first set of samples that is before the chosen point and a second set of samples that is after the chosen point, performing the detecting of the payload on a combination of the first set and a transformation of the second set, where the transformation is based on the assumption that the second set is from the second segment and exploits the relationship that exists between the payloads in the first and second segments.
