Scalable watermark insertion for fragmented media stream delivery |
摘要 |
<p>A media stream is delineated into multiple fragments. Different watermark variants of individual fragments are generated. Particular sequences of watermark variants are selected for particular clients and maintained in a user access database. Analyzing media streams allows determination of the sequences of watermark variants and identification of particular clients intended to receive the media streams. Fragments can continue to be cached efficiently and unique watermarks need not be generated for each individual client.</p> |
