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。
