Video Copy Protection (e.g., Anti-copy, Etc.) Patents (Class 386/252)
  • Patent number: 8059937
    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.

  • Patent number: 8050536
    Abstract: The CGMS unacceptable recorder accepts transmission frames only when the copyright protection information in a transmission header transmitted to the IEEE1394 serial bus indicates copy free. The CGMS acceptable recorder accepts transmission frames when the copyright protection information in the transmission header indicates copy free. When the copyright protection information in the transmission header indicates compliance with the copyright information contained in the content of the transmission frame, the copyright information in the content is fetched based on the signal format type information of the transmission header. As described herein above, a copy management information changeable apparatus such as a computer cannot accept data other than copy free signals from the digital interface.

  • Patent number: 8041185
    Abstract: A system and method of determining the copy protection features of a program, and notifying a potential user of the program of these features, is provided. The copy protection features of the program first are analyzed. On the basis of this analysis, a message such as “this program cannot be recorded with IEEE1394, optical digital audio” is displayed to the user. By displaying such a message, the user can easily recognize that copy protection is applied to the program and that, for example, the program can be recorded (picture-recorded) in an analog style but cannot be digitally recorded. Accordingly, the user is easily made aware of the copy protection features of the program before using or purchasing the program.

  • Patent number: 8032006
    Abstract: A method and apparatus are described for modifying an analogue video signal to impair its conversion to a digital signal by an analogue to digital converter. The resulting modified signal may prevent the operation of the analogue to digital converter altogether, or even if a digital signal can be output and recorded, may result in a signal which is difficult to view due to a reduction in quality on playback. The modifications made to the signal include altering the amplitude of the horizontal synchronization pulses in the original signal, and/or modifying the level of the back porch, or the region of the signal adjacent the back porch. Additionally, methods are contemplated for the use of specific response models for target analogue to digital converters, and display devices.

  • Patent number: 8032008
    Abstract: There is provided a content recording/reproducing apparatus that can restore a deleted content. An MD recording player (1) as an example of the content recording/reproducing apparatus records, each time a content recorded in a mini disk (90) is deleted, information on the deleted content to a deletion history. Since a personal computer (200) as an external device re-records the content deleted in the MD recording player (1) on the basis of the content of the deletion history, so the user has not to re-record the deleted content by remembering what the deleted content was. Also, even if a content checked out to the MD recording player (1) is deleted, the number of times of check-in or check-out is matched with the content data by making deemed check-in on the basis of the deletion history or recording history.

    Abstract: To provide a recording and reproducing apparatus that recovers contents having approximately the same quality as the original contents in a short time and requiring only light processing load, at the time of (a) moving the contents from the first recording medium to the second recording medium, (b) rewriting the contents in order to disable reproduction of the contents, (c) reconstructing the original contents by recovering the contents from the second recording medium to the first recording medium. The recording and reproducing apparatus includes a move processing unit 72a and a recovery processing unit 73a. The former records reconstruction information on the second recording medium in association with the second contents, the reconstruction information being used in reconstructing one or more parts of the contents that have been rewritten in order to disable reproduction of the contents at the time of moving the contents.

  • Publication number: 20110206343
    Abstract: An integrated circuit or system receives a bit pattern from a metadata, IPG, and or EPG signal. This bit pattern is then coupled to a circuit to provide a content control command to a recorder or to a processing circuit to generate a content control signal. In particular the bit pattern may be utilized in a manner to program, enable, or disable the generated control signal. Furthermore this content control signal provides resistance to a circumvention device. For example, the circumvention device is unable to remove sufficiently the content control signal, and content control is maintained.

  • Publication number: 20110206349
    Abstract: A method, apparatus and system for anti-piracy protection and verification include a first projection device configured to project image frames onto a screen. A feedback device records a plurality of consecutive frames, an image analyzing module analyzes image properties of the recorded frames and a modulator creates anti-sampling system content to be projected contemporaneously with the image frames. The projected anti-sampling system content, while virtually invisible to the human eye, is detectable by sampling systems such as camcorders, thus rendering any such pirated recordings of the protected image content useless. The first projection device can include a security processor configured for comparing the recorded content with an expected content in real-time. A display enable/disable module is provided for disabling the projection of the content on the screen if the recorded content does not match the expected content.

  • Patent number: 8000582
    Abstract: A system and method are described for rendering Compact Discs (CDs) and Digital Video Discs (DVDs) unreadable. Embodiments comprise a frame, a guide for constraining motion of the frame with respect to a disc, and at least one scraping element. Scraping elements may be positioned to damage the disc volume descriptor while the frame moves in a constrained manner relative to the disc. The guide may comprise a spindle which engages the center hole of a disc to hold the frame in a radially-fixed position. A scraping element on the frame damages the disc as the disc rotates relative to the frame. The guide may be integrated, such that the frame comprises a slot through which the disc passes. A scraping element inside the slot damages a disc as it passes through. Embodiments are hand operated, not motorized, and some have no moving parts. Embodiments also function with non-optical media.

  • Patent number: 7941033
    Abstract: In case continuous reproduction is commanded from a first AV stream to a second AV stream, a third AV stream, made up of a preset portion of the first AV stream and a preset portion of the second AV stream, is generated. The third AV stream is reproduced when reproduction is switched from the first AV stream to the second AV stream. As information pertinent to the third AV stream, the address information of a source packet of the first AV stream at a time of switching from the first AV stream to the third AV stream and the address information of a source packet of the second AV stream at a time of switching from the third AV stream to the second AV stream, are generated. This enables reproduction such as to maintain continuity between separately recorded AV streams.
