| 摘要 |
<p>The invention relates to a method for effectively converting non copy protected data (1) into copy protected data (5). The non copy protected data (1) comprises data structure data, controlling data and content data. The content data are embedded into data structures defined by the data structure data, and are processible by using the controlling data. The method comprises the following steps:
- transferring at least parts (9) of said data structure data and/or said controlling data via a first communication network (3), from a first network location (2) to a second network location (4),
- generating modified data structure data and/or modified controlling data at said second network location (4) in dependence of said data structure data/controlling data supplied to said second network location (4),
- transferring said modified data structure data and/or modified controlling data via a second communication network (6) from said second network location (4) to a third network location (2),
- generating, at said third network location (2), said copy protected data by embedding said content data into modified data structures being implied by said modified data structure data and/or by replacing said controlling data by said modified controlling data.</p> |
