Abstract
Apparatus and a method are described for providing, for recordal onto a recording medium, recording data having content data and control data for enabling a player playing such a recording medium to navigate through the content data. The apparatus has a copy protector to copy-protect the recording data by controlling the production of parameters that are associated with items of data in the recording data but that are not checked by a physical testing device such that a parameter associated with an item of the recording data that is not on the navigation path is inconsistent with that item of data, or is otherwise not as expected, to cause a copying device reading that the item of data to report an error, thereby inhibiting copying by that copying device.
