Abstract:
Methods for providing content session information using a content manager, streaming server, and one or more watermarking devices are disclosed. A content asset is also disclosed. The content asset may include content. In addition, the content asset may include a content data field having forensic watermark information, e.g. session or identifying information. In one aspect, the content asset is compressed and the compressed content asset has one or more pre-processed candidate watermark locations. In this aspect, the forensic watermark information may be extracted, e.g. by a watermarking device, from the content data field and included in the one or more pre-processed candidate watermark locations.
