摘要： A playback device includes a port configured to receive content from an external memory device, a device memory residing in the device, and a controller programmed to execute instructions that cause the controller to read a data pattern from the defined region in the external memory device and determine if the data pattern correlates to an expected data pattern, wherein the expected data pattern is derived at least in part from a defect map A method of validating a memory device includes writing, using a controller in a playback device, a known data pattern to a defined region in the memory device, reading a data pattern from the defined region, comparing the read data pattern to an expected data pattern derived from the known data pattern and a defect map of the defined region, and validating the memory device based upon a correlation result from the comparing

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： Recording data has content data and navigation control data to enable a legitimate player to navigate the content data. The recording data has a content data set and a spurious data set that is difficult to distinguish from the content data set but will be ignored by a legitimate player. The content data is associated with the content data set and the spurious data set. The spurious data set may be associated with control data that inhibit playing or correct playing of the content data. A ghost structure such as a ghost video title set may be provided by causing information in at least one of the video title set information, video manager information and the volume information file structure to reference a non-existent video title set or not reference an existing video title set. The recording medium may be an optical disc such as a DVD or its precursor.

摘要： A recorder/reproducer (101) writes second content data produced by re-encoding first content data recorded on a first recording medium onto a second recording medium in place of the first content data when it is transferred, writes one or more first partial information extracted from the first content data onto the second recording medium, and alters the first content data into non-reproducible state using one or more first invalidated partial information corresponding one by one with the extracted one or more first partial information. The recorder/reproducer alters the first content data under non-reproducible state into reproducible state using one or more first partial information recorded on the second recording medium when recovering the first content data.

摘要： A system for reducing supply chain theft comprising a medium having a state-change material associated therewith that is activatable from a first detectable state to a second detectable state by an activating wave that is energetically different from the read- wave of the reader, thereby altering the medium from a limited read medium to a more open read medium; an activation unit operatively configured to direct activating waves to the optical medium such that one-way state-change material associated with such optical medium is activated from a first state to a second; and a verifier unit operatively configured to determine whether the one-way state- change material is its first or second optical state.

摘要： An optical disc is provided with an associated optical shutter. In a first state, the optical media interferes with the ability of an interrogating laser beam to read data from the optical media, and in a second state, the optical media is substantially transparent, enabling the laser beam to read the disc. A powering circuit is used to cause the optical shutter to transition from a first state to the second state. In one example, an integrated circuit acts as the powering circuit, as well as providing logic and processing functions. The integrated circuit also couples to an RF antenna, enabling the integrated circuit to communicate with an associated RP scanning device. The optical shutter may take various geometric shapes, and typically has an electrochromic material for facilitating state change. The electrochromic device may be constructed to hold persistently the desired optical state. In this way, the desired optical state is maintained without application of external power.

摘要： The invention relates to a record carrier (1) comprising an information area (2) for storing information, and an integrated circuit (3) comprising a storage unit (4) for storing additional information AK and Rights. The integrated circuit further comprises a one-time programmable memory (5) comprising a resurrection key RK, the one-time programmable memory having a substantially larger data retention time than the storage unit. If the additional information present in the storage unit is lost or has degenerated, it is possible to restore this information by using the resurrection key present in the one-time programmable memory.
