20080205848 | Imaging apparatus and reproducing apparatus - An imaging unit takes an image and converts the image into a video signal. A display unit displays the image carried the by the video signal. An average luminance calculating unit calculates average luminance of the image per first predetermined period. A detecting unit calculates a ratio of maximum to minimum average luminance of the average luminance over a second predetermined period that is an integer multiple of the first predetermined period and determines whether the ratio is equal to or higher than a predetermined value. The detecting unit determines that the image taken by the imaging unit is an image of a movie projected onto a screen when it is determined that the ratio is equal to or higher than the predetermined value. A warning unit sends a warning signal to the display unit when the detecting unit determines that the image taken by the imaging unit is the image of the movie. The display unit then displays an warning message carried by the warning signal with the image. | 08-28-2008 |

20100021133 | METHOD FOR COPY PROTECTION FOR VIDEO SIGNAL WITH ADDED PULSES - Enhancements to a video anticopying process that causes an abnormally low amplitude video signal to be recorded on an illegal copy. In one version, positive going pulses are added to the video signal. The enhancements in one version introduce into the overscan portion of the television picture, just prior to the horizontal or vertical sync signals but in active video, a negative going waveform that appears to the television receiver or videotape recorder to be a sync signal, thereby causing an early horizontal or vertical retrace. One version provides (in the right overscan portion of the picture), a checker pattern of alternating gray and black areas which causes the TV set on which the illegal copy is played to horizontally retrace earlier than normal in selected lines with a consequential horizontal shift of the picture information on those lines. This substantially degrades picture viewability. In another version a gray pattern at the bottom overscan portion of the picture causes vertical picture instability. In another version selected horizontal sync signals are narrowed, causing irregular vertical retraces. Also provided is apparatus for removing or attenuating these enhancements from the video signal, to allow copying. | 01-28-2010 |

20100046915 | INFORMATION PROCESSING APPARATUS, DISK, INFORMATION PROCESSING METHOD, AND PROGRAM - An information processing apparatus includes a data processing unit that verifies data recorded on a disk and reproduces content recorded on the disk if a verification condition is satisfied. The data processing unit verifies the validity of an ID inserter that has recorded, on the disk, an ID corresponding to the disk. The data processing unit acquires an ID inserter certificate containing an apparatus ID of the ID inserter that has recorded the ID corresponding to the disk on the disk and an ID inserter blacklist having apparatus IDs of invoked ID inserters registered therein, determines whether the apparatus ID contained in the ID inserter certificate is registered in the ID inserter blacklist so as to verify the validity of the ID inserter that has recorded the ID corresponding to the disk, and stops reproduction of the content if it is determined that the ID inserter is not valid. | 02-25-2010 |
20100054698 | APPARATUS, METHOD, AND COMPUTER PROGRAM PRODUCT FOR RECORDING CONTENT - An apparatus determines whether a combination of a certificate type of a content certificate recorded on a source recording medium and a medium type of the source recording medium is a proper combination. If the combination is a proper combination, the apparatus requests a license server, which is connected to the apparatus via a network, to give approval to record content on a target recording medium. If the apparatus is a legitimate DVD recorder, the license server sends to the content recording apparatus a content certificate including on the source recording medium as the certificate type. The apparatus records the content together with the received content certificate on the target recording medium. | 03-04-2010 |
20100054699 | METHOD AND APPARATUS FOR DISPLAYING VIDEO SIGNAL DATA WITH PROTECTION AGAINST DIGITAL COPYING - New movies from content providers are often made available on the Internet before being launched in the cinemas. Pre-released movies like DVD Videos for journalists are the main reason for this situation because some journalists seem to make these movies available to the Internet users. However, this causes significant harm to the content providers. According to the invention, the pre-releases are still DVD Videos or other conventional video formats but the playback of such encoded video signal is not possible using only a conventional DVD player or DVD player software because the playback requires additional hardware. An additional box (CP splitter box) splits the original video signal into two different video signals to be projected using two different beamers (A, B) which both are required for generating the whole video content. The beamers have different locations each with a different angle to the silver screen, and each beamer generates only a part of the video. | 03-04-2010 |
20100054700 | Method and apparatus for providing in a media player a copy protection signal that negates a circumvention device and or provides improved playability - A media player provides a new copy protection signal which causes resistance to certain circumvention devices and includes improved playability. The new copy protection signal causes the certain circumvention devices to pass substantially the copy protection effects to a video recorder, or causes content control effectiveness on a compliant device. That is, the new copy protection signal from the media player causes the circumvention device to add or enhance copy protection effectiveness, which is contrary to the circumvention device's original intent of removing or reducing copy protection effectiveness. The new copy protection signal is provided by inserting or adding one or more pseudo sync pulses or one or more pseudo sync/AGC pulse pairs immediately after, one line after, or less than two and a half lines after, a vertical sync signal in at least one television line. Thus, the media player utilizes the new copy protection signal to thwart various intended functions of the circumvention device. | 03-04-2010 |
20100054701 | REAL-TIME SOFTWARE VIDEO/AUDIO TRANSMISSION AND DISPLAY WITH CONTENT PROTECTION AGAINST CAMCORDER PIRACY - The invention presents new methods of compression, transmission, and decompression of video signals providing increased speed and image quality and for protecting against camcorder piracy. Methods based on selecting an anchor frame, wavelet transformation with decimation and time stamping can provide one-pass encoding of signals in which the amount of bits of information needed to be transmitted can be substantially reduced, thereby increasing the speed of transmission of digital signals over networks. Decompressing signals, along with interpolation methods to re-create portions of images of lesser importance in visual perception, can provide coordinated video and audio presentations of high quality in real-time over all kinds of networks and frame interpolation resulting in a displayed frame rate significantly higher than 30 fps. The use of randomly selected anchor frames can render reconstructed transmitted images of poor quality for pirates who do not have access to identities of anchor frames. | 03-04-2010 |

20100111496 | METHOD AND APPARATUS FOR SYNTHESIZING OR MODIFYING A COPY PROTECTION SIGNAL USING A LOWERED SIGNAL LEVEL PORTION - A modified Colorstripe™ copy protection process utilizes a basic anti-copy protection (ACP) signal that causes attenuation of a video signal, wherein, in one embodiment, the process modifies (lowers) the level of a front porch portion and adds an incorrect color signal (color burst) in the region of the sync tip. When an illegal copy is made, a pre-blanked end of line portion causes a TV set to trigger the color burst sample pulse ahead of time and cause the incorrect color signal in the sync tip region to be sampled. Thus, since the sync tip region has incorrect color phase or frequency, the resulting illegal copy will have enhanced color distortions. In other embodiments, other portions of the horizontal blanking interval are lowered in level and incorrect color bursts are added to a portion or portions of the back porch and/or a portion of the front porch. The various embodiments of the process may include an adaptable process, as well as several alternative ACP signals for use in combination with the process. | 05-06-2010 |
