摘要： Recording data for an optical disc such as a DVD has video content data and navigation data. Button data defines one or more user-selectable selection buttons to enable a viewer to select content data when the recording medium is played. Further button data defines at least one phantom button that is not selectable by a viewer because, for example, it is not visually distinguishable, it is hidden within the video data or it is displayed for a short period of time. Although the at least one phantom button is not selectable by a viewer, a copying apparatus parsing the recording data will erroneously identify the phantom button as a user-selectable selection button and will copy data associated with the phantom button. The data associated with the phantom button may adversely affect the copying process or render the copy unplayable or unwatchable.

摘要： To copy protect an optical disc, such as a DVD, program chains additional to the main program chain are provided. These program chains may lead to the genuine data but in an incomplete or incorrect order or to false data. Sufficient additional program chains are provided to make it difficult to identify the main program chain amongst all of the program chains provided on the disc. The structure of the further program chains ape that of the main program, again to hide the main program chain. The navigation path which leads to the main program chain, and hence to the content on the DVD, is dynamically generated and at least some of the information required to generate the navigational path arises by setting parameters associated with a player or with a user. Thus a search of all of the navigation information on the disc will fail to reveal the navigation path to the content.

摘要： A method for copy protecting a record carrier is disclosed, in which method the copy protected record carriers are provided with a pattern of logical errors which cannot be corrected by the error correcting rules predefined for said record carrier. The pattern of logical errors represents access control information. The logical errors are generated during decoding the bit sequence read from the record carrier. Bit errors may be positioned in the bit sequence so as to counteract de-interleaving which is part of an error decoding process in a reading device and accumulate in error words which are uncorrectable. Also a method for detecting access control information and a retrieval arrangement are disclosed, which retrieval arrangement serves to detect the access control information by selecting at least one error location, but not all error locations on the record carrier, and verifying the presence of an error by reading the selected error location via the reading means.

摘要： A copy-protection scheme is implemented for software which may be stored on a magnetic storage medium such as a disk. The medium is comprised of sections which are divided into subsections, with an original having indicia on at least one subsection of at least one section that is not modifiable by the medium write process, with a copy having no such indicia, or having indicia in a different pattern. A product program may be stored on the medium, and is executable only if the particular medium is an original. A medium test program may also be stored on the particular medium, and is used to test if the medium is an original or a copy. The test program writes the sections with a test pattern which generates a change in the pattern of magnetic domains of the medium, a subsection at a time, with a subsection responding to the test pattern only in the absence of indicia thereon, to form a stored pattern on the given section. An expected pattern and the stored pattern are compared at least a subsection at a time to determine if corresponding subsections have a predetermined pattern of magnetic domains. The product program is executed only in response to the comparison determining that corresponding subsections have predetermined patterns of magnetic domains which is indicative of the presence of said indicia, and the particular medium being an original.

摘要： 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.
