Abstract: A correlation-based system for watermarking continuous digital media at the system application level. It is a post-compression process for watermarking where no a priori knowledge of the underlying compression algorithm is required. Per each compressed media frame, a current unique digital signature is generated based on the data from the current compressed frame plus the digital signature that has been previously generated. The signature thus generated is then used in conjunction with the next compressed frame to generate the next unique digital signature. All digital signatures are correlated according to the above process until a “reset” signal is issued. A new chain of correlated digital signatures is produced by the system with a pre-determined initial signature.

Abstract: A process and facility supports recipient-specific customization of mass-duplicated tapes. Video from a master tape is passed through a VBI encoder whose output feeds two or more overlay units, each associated with a tape recorder. Recipient-specific watermarking instructions and address information for each tape are fed to the VBI encoder where they are encoded into the VBI of the video. Each overlay unit reads the VBI and decodes the address, and if relevant for that unit, applies the overlays to the video, which is recorded by its associated recording deck. Optionally, each tape and overlay unit includes a barcode that is scanned into a database where associations between tapes and the overlays are stored. Alternatively, high-density barcode labels that include the overlay instructions are printed and applied to tapes. The barcodes are scanned into the overlay units and applied following the receipt of a timecode or other trigger.

Abstract: A user gestures with a wireless mobile phone device to control some aspect of its operation, or the operation of a remote system with which the device communicates. Application programs can solicit gestural information through a standardized set of interface protocols (e.g., API functions). One function, for example, solicits a running set of gesture data, and a complementary function discontinues the first function. Other functions solicit device movement data in particular directions. In some arrangements gesture data is sent by the wireless device to a remote system, which may issue a response that is dependent on the received gesture data. This response may also depend on other data obtained by the wireless device (e.g., obtained from an electronic or physical object, or sensed from the environment) and sent to the remote system. The wireless device may have different modes of interacting with users, to accommodate users with greater or lesser proficiency in gestural techniques.

Abstract: Generally the more effective is the copy protection provided on an optical disc, such as a DVD, the greater is the likelihood that the copy protection will adversely interfere with legitimate uses of the optical disc. It is therefore proposed to include at least one region of subversive data within the content in the data area of an optical disc, and then to prevent access to each such region of subversive data during normal playback of the disc. For a DVD, the subversive data may be incorporated within video objects and/or may be in gaps between files in the DVD_Video zone. It is arranged that there are no navigable paths to the regions of subversive data.
