摘要： A system for providing security and tracking data for rental video media, including digital video discs and digital video cassettes. Those new formats for video players and media allow for inclusion of security features which both allow tracking of rental of such media and prevent unauthorized rental thereof. Each player includes a decision circuit which plays a particular disc (or tape) only if a player identification number recorded on a special separate authorization memory card is the same as the player identification stored in the player, and if a movie identification number optically read from the disc matches a movie identification number recorded on the special card. A corresponding apparatus is provided at the video rental store which, at the time of rental, records on the authorization card in encrypted form the movie identification number and the number of the particular disc player for which that rental is intended. The encryption uses the private key of a public key system, the public key and the modulus being pre-recorded on the optical portion of the disc.

摘要： A method and apparatus for copyright protection for various recording media such as Digital Video Discs (DVDs) uses a combination of a Video Finger Print Signal and an Authenticating Signature to permit the player to handle either copy-protected or non-copy-protected media, in a manner that is difficult to compromise. Both a Video Finger Print Signal and an Authenticating Signature are recorded on the media only when copy-protection is required. The nature of this Authenticating Signature is such that it will not be transferred to illicit copies made on CD recorders. When either an original protected or an original non-protected disk is played, the presence or absence of the Authenticating Signature causes the player to correctly play the program video. All original DVDs therefore play normally. When a copy of a non-protected CD is played, the absence of the Video Print Signal also causes the player to correctly playback the video signal data. However, when a copy of a protected CD is played, the absence of the Authenticating Signature causes the player to prohibit the disk from playing normally.

摘要： A method and apparatus is disclosed which reduces or removes the effectiveness of commercial skip systems such as presently found in VCRs, PVRs, etc. which are designed to delete commercials from signal material upon playback of a previously recorded version of the signal material. In an embodiment, the effectiveness of the commercial skip system is reduced or removed by adding a flat field of selected signal level to active line portions of video lines of the signal material. Other embodiments modify the normal fade to black signal indicative of a commercial to provide a fade to non-black signal. In further embodiments, a fade to non-black signal is inserted in an overscan area of the signal picture. Still further embodiments modify audio signals or selected signals in the horizontal blanking interval which may be used in commercial skip systems to detect the presence of commercials.

摘要： Method and apparatus for scrambling a high definition television signal to discourage unauthorized recording of same. While recording per se is not prevented, the resulting recorded signal is rendered unusable due to an induced “wobble” between the active video and the associated sync pulses. The scrambled television signal is readily viewable on a compliant high definition television set which descrambles the HDTV signal using an encoded indication of the amount of wobble accompanying the HDTV signal. Also provided is a special interface to prevent unauthorized persons from using the indication of the amount of wobble so as to defeat the scrambling. Also provided are method and apparatus for defeating the scrambling method and hence allowing recording of the scrambled video signal.

摘要： A method and apparatus for modifying a video signal to allow it to carry encoded data which is detectable at a suitably compliant receiver but is not recorded by a conventional video recorder. One application is to carry a descrambling key to prevent useful recording (but not viewing) of a scrambled television signal since the key will not be recorded. This encoded “hidden” data is not recorded by the conventional video recorders because, for instance, it is located in the vertical or horizontal blanking intervals of the video signal, or is carried by a high frequency carrier signal, or is expressed by phase modulation of the video signal's synchronization pulses.

摘要： Fingerprinting and fingerprint detection, techniques are described which, unlike typical fingerprint systems used to conceal video signals, are compatible with all conceivable forms of signal compression systems while still allowing viewing of the video signal. The fingerprint technique is based on the principle of applying very slight local spatial distortion to the pixels in a video image, and the like, by means of selected warp patterns. Thus the technique provides means for conveying, within the video signal, selected information in the form of the fingerprint which is detectable electronically but which is not noticeable to a critical viewer who is watching the video signal. That is, the resultant fingerprinted video signal will appear to be identical to the undistorted video signal. the fingerprint detection technique provides for the recovery of the conveyed information which may comprise an instruction to prevent the fingerprinted video image from being copied, messages which allow identifying the source and date of an unauthorized copy of the video image, etc.

摘要： In the known color stripe process for preventing recording of video signals, the color burst present on each line of active video is modified so that any subsequent video tape recording of the video signal shows variations in the color fidelity that appear as undesirable bands or stripes of color error. This color stripe process is defeated first by determining the location of the video lines including the color stripe process, either by prior experimentation or by on-line detection. Then some or all of the lines including the modified color bursts are modified so as to render the overall video signal recordable. The modification is accomplished in a number of ways, including phase shifting the color stripe burst into the correct phase, replacing some of the color stripe bursts or a portion of particular color stripe bursts so that they are no longer effective, and mixing the color stripe burst with color stripe signals of the correct phase so as to eliminate most or all of the phase error present. The modified color bursts are defeated, in other versions, by modifying the horizontal sync pulse signals immediately preceding the modified color bursts so that the modified color bursts are not detected by a VCR and hence have no effect.
摘要翻译：在用于防止视频信号记录的已知色条过程中，修改存在于每个有效视频行上的色同步信号，使得视频信号的任何后续录像带记录显示出作为不期望的条带或条带出现的色彩保真度的变化颜色错误。首先通过先前的实验或通过在线检测来确定包括彩色条纹处理在内的视频行的位置来消除这种彩色条纹处理。然后修改包括修改的彩色脉冲串的一些或所有行，以便使整个视频信号可记录。该修改以多种方式实现，包括将彩色条纹突发相移到正确的相位中，替换一些彩色条纹突发或特定颜色条纹突发的一部分，使得它们不再有效，并且混合色条以正确相位的彩色条纹信号突发，以消除存在的大部分或全部相位误差。在其他版本中，修改后的色同步信号通过修改在修改后的彩色脉冲串之前的水平同步脉冲信号而被消除，使得修改的色同步信号不被VCR检测，因而没有影响。

摘要： A video recording platform prevents both analog and digital copying of copy protected material. The platform may input and output both analog and digital video signals. At said analog input, a detector detects conventional copy protection in the analog input video, and in response disables recording thereof. At the digital input, a first detector detects a copyright signature present in the input material and in response prevents recording. A specially adapted video recorder, playback device or set top decoder copy protects video source material which has a copyright signature. A copyright signature is provided in a predetermined location in said video signal to be protected. The video recorder, playback device, or set top decoder upon detection of the copyright signature on its input or at playback, modifies the output standard (NTSC) video signal with a conventional copy protection process and the digital output with a new copyright signature. The input digital signal may contain a scrambling of the digital video signal in addition to the copy protection signature. In addition, an authenticating signature may be added to the digital video signal and detected as part of the copy protection process. As part of the copy protection, a television receiver includes a copy protection and descrambling system.

摘要： A video-scrambling system induces a random wobble i.e., time shifting, in the location of active portion of the video frame, without affecting the horizontal sync signal and colorburst in each video line, thus providing both security and concealment. The security is enhanced by filling in the gap between the nominal beginning of active video and the actual beginning of active video with a synthesized video signal which replicates the adjacent active video using a digitally generated filling pattern. Also, a random noise overlay further conceals the location of the gap. Additional concealment is provided by wiggling in time the location of the horizontal sync signal using one or two frequencies and also by randomly altering the location of the vertical sync signal. The NTSC digital encoding in accordance with the invention is simplified by using only two channels, chrominance and luminance, and by a heterodyne circuit for chrominance stability. NTSC encoding is enhanced by providing detail normally lost, by use of the chroma channel. Additionally, a non-standard video signal may be provided with a portion of the colorburst on the front porch of the horizontal blanking, thus allowing use of a relatively simple decoder.
