Abstract

Method for converting non copy protected data into copy protected data. The non copy protected data includes data structure data, controlling data and content data. The content data are embedded into data structures defined by the data structure data, and are processed using the controlling data. The method includes transferring part of the data structure data or the controlling data via a first network, from a first to a second network location, generating modified data structure data or modified controlling data at the second network location based on the data structure/controlling data supplied to the second network location, transferring the modified data structure/controlling data via a second network from the second to a third network location, where the copy protected data is generated by embedding the content data into modified data structures based on the modified data structure data or by replacing the controlling data with the modified controlling data.
