Disclosed is a system configured to process content to enable tracing of at least one of a multitude of subsequent uses of content by at least one user. The system provides for: making markable content from content, iteratively marking the markable content with information such as use information; and later extracting at least one of the iteratively applied marks.

Tracing content usage

A content distribution system and method which prevents unauthorized access to secured content such as movies and music. The system includes a source, a receiver, an authorized security device such as a conditional access module (CAM) for decrypting authorized content and an output device for outputting content. The system can also include a backend for managing accounts and system operations. One aspect of this invention is that the content data is derived from the Internet. The system allows for the verification of authorization to play secured content, the addition of watermarks to the secured content, the conversion of the secured content to a displayable form and the means for preventing output of the secured content.

Digital content distribution system and method

Disclosed is a secure remote repeater. The secure repeater includes a first remote control signal detector, a remote control signal processor and an emitter. Among other functions, the secure repeater can forward secure remote signals to an electronic device using non-secure commands native to that electronic device. Additionally, the secure remote repeater can filter remote signal chatter.

A visual copyright protection system is disclosed, including input content, a disruption processor, and output content. The disruption processor inserts disruptive content to the input content creating output content that impedes the ability of optical recording devices to make useful copies of output content.

Optical content modulation for visual copyright protection

The present invention is a system for securing broadcasting content locally at receiving stations that may be remote to a broadcaster. Embodiments of this invention implement controllable and renewable security measures, compatible with many other content processing and display systems. These security measures may include re-encrypting received broadcast content using locally generated keys, watermarking the received broadcast content, and logging both processing and display of broadcast content.

Local content security system

Visual copyright protection

A content distribution system and method which prevents unauthorized access to secured content such as movies and music. The apparatus includes a source, a receiver, an authorized security device such as a conditional access module (CAM) for decrypting authorized content, an output device for outputting content and a backend for managing accounts and system operations. One aspect of this invention provides a mechanism for providing secured content on a medium such as a DVD optical disc. These devices may verify that there is authorization to play the secured content, add watermarks to the secured content, convert the secured content to a displayable form and provide a means for preventing output of the secured content.

A safety mailbox system including a mailbox container integrated with at least one decontaminating mechanism is disclosed. Contaminants may include chemical and biological agents.

A structure and method are described that make it possible to store both open-format data and closed-format data on a single storage medium, such as a DVD disc, by organizing the data in an open file data system and a specialized closed file data system. The closed file data system may be encapsulated in the open file data system The storage medium is segmented into open file data spaces, containing data recorded using the open-format techniques, and closed file data spaces, containing data recorded using closed-format techniques, or using a specialized technique. The open-format data can be accessed using both open-format and close-format hardware, whereas the closed-format data can only be accessed using specialized hardware.

System and method for implementing open and closed file systems on a storage medium

To enable the source of an unauthorized copy of an information-bearing medium, such as a video DVD, to be traced, a compressed digital signal stream to be stored on the medium is altered to include &ldquo;running marks,&rdquo; that comprise pixel blocks changing in position frame by frame and encoded with information designating where and when the copy was made. The medium under test is played back synchronously with a reference medium containing the locations of the running marks together with original video. The source of copying message is advantageously encrypted and scrambled to avoid detection or alteration by a copyist. The message preferably is spread, for example into a spread spectrum carrier, to enhance discrimination among a large number of sources and enable demodulation in the presence of noise.

A system and method for tracking and processing transactions for such purposes as creating billing record and detecting possible fraudulent activities. The system and method relates to processing transactions associated with viewing movies, e.g. a video content distributed digitally on a digital video disc (DVD) in an scrambled format, where the video content is only viewable in conjunction with the use of a specially designed and enabled player. This method of distributing and billing movie content provides an alternative to current methods such as viewing via video tapes, open format DVDs, pay-per-view, or cable service. The system and method permits a user to establish, via a single authorization, multiple access to a service during a period of time, where each event of access is not individually billed. The system and method does not create a billable charge for a user authorization if the user does not actually access the service. Furthermore, the system and method requires a user to initiate a new authorization after the original authorization has expired, in order to re-access the service. Additionally, the system and method provides one or a plurality of devices local to the user, electronically linked to a remote host, in order to create, store and transmit records of authorization and access to a remote central processor in a secure manner.

Graphics in the same compressed digital format as that of a target video image are combined, on the fly, by an application. Combination is performed by frame modification or overlay techniques. In the preferred embodiment, the compressed video image format conforms to an MPEG-2 compression standard. A base image is produced by an I-frame, and MPEG-2 graphics elements formed either by modifying the I-frame or overlaying the I-frame with one or more P-frames.

Compressed video graphics system and methodology

A colorgraphics recorder has a cathode ray tube with three parallel strips of light emitting phosphor, each emitting in one of the primary colors, with the light emitted from the phosphors focused on a film frame held in a film carrier. Each of the parallel strips of phosphor on the CRT can have a number of individually illumable pixels, forming a column of pixels. The light from each pixel at the same row level in each of the three strips of phosphor may be focused onto the same spot on the film frame so that all three of the primary colors are exposed at the same time at each pixel in the column of pixels exposed on the film frame. The film frame may then be indexed over one pixel width and the process repeated to expose another column of pixels in each of the three primary colors. Continued repetition of the process across the entire width of the film frame completes the exposure of the frame. Alternatively, the pixels on each of the three strips of phosphor on the CRT may be focused separately onto the film frame, forming three separate columns on pixels exposed in the three different primary colors. The intensity of the pixels exposed for each of the three colors is appropriate for the particular position on the film frame of the column of pixels that is exposed. The film frame is then indexed over one pixel width and the process repeated, with the tracing of the pixels on the CRT selected such that, for example, a column of blue pixels previously exposed on the film frame has a subsequent exposure by a column of green pixels, and another subsequent exposure by a column of red pixels, so that all of the three primary colors for all of the pixels in that column are exposed. This process is repeated, indexing the film frame one pixel width at a time until the entire frame of film is exposed.

Computer graphics color film recording method and apparatus

A photoplotter wherein a relative movement is produced between a photosensitive media and a radiant energy pattern generated on the media. The relative movement is in accordance with a desired exposure trace on the media. A difference between actual and desired relative movement is detected and the radiant energy pattern is varied to compensate for that difference. In a preferred embodiment, the radiant energy pattern is established by a pattern generator which displays an alterable pattern object on its face the position of the pattern object on the face being variable to compensate for the difference between actual and desired relative movement. The pattern object may be generated as a linear trace on a cathode ray tube (CRT) with the number of linear traces generated per unit of time being dependent on the relative movement velocity. The pattern images on the media resulting from the linear CRT traces or pattern objects overlap to provide a continuous exposure pattern along the desired exposure trace.
