Abstract: A more efficient method of recording programs simultaneously is provided in one embodiment by translating certain bands of the RF spectrum and translating and or reordering the channel allocation into a (analog) spectrum of one or more lower intermediate frequency band(s). A recorder records the analog RF spectrum, which then is available for playback from the recorder. Programs contained in the played back RF spectrum are selectively extracted by means of a tuner and or demodulator for subsequent viewing, listening, or distribution. Alternatively, an RF signal is supplied to a recorder for recording or storage without translation. The recorder then plays back the RF signal to a tuner and or demodulator for display and or distribution.

Abstract: The "color stripe" process is well known in the video field for preventing copying of video by analog video tape recorders, and operates by altering the phase of a portion of the video signal color burst. Here, a weakened version of the color stripe process is installed in a video signal by a digital media player which plays or stores conventional digital media, such as an optical disc (e.g., DVD or CD) player, a hard disc drive, a digital tape drive, or solid state memory. Thereby in an analog video signal output by such a digital media player the color burst phase alterations are reduced or attenuated so there is no copy prevention effect on a conventional downstream (receiving) analog video tape recorder. However the weakened color stripe process is still sufficient to be detectable by a suitable detector located in a downstream compliant device such as a video recorder, so the detected presence of the installed color stripe serves as an encoded indication of copy control or other content control for the video signal by the compliant device.

Abstract: Method and apparatus for ensuring the security of configuration or programming data supplied to an electronic device, such as a video consumer electronic device. This is achieved by storing within an integrated circuit video processor in the device both logic and data for checking the security of input configuration and/or programming data for the video processor to detect and prevent tampering with same. Not only is it determined if the input data is correct versus unacceptable, also if it is determined unacceptable, the logic then determines if the input data is the result of an innocent error or tampering by a hacker and takes appropriate protective steps accordingly.

Abstract: Method and apparatus for content control of television signals which operate over multiple television standards and include flags, control bits, data copy, copy protection signals and/or video modification signals. Content control for high definition television signals is provided operative with television-type devices, such as television transmitters, signal translators, recorders, players and others. This approach to content control is intended to operate both with the legacy analog television standards and new higher definition television standards, including the various HDTV standards to convert and detect content control information for use across standards. Thus this provides a multiple standard definition television content control apparatus and method with cross -platform capabilities

Abstract: A high definition television video content management and/or copy protection method and apparatus are achieved by modifying portions of one or more channels of an HDTV (high definition television) signal. These modifications are generally in the blanking intervals but can extend into the overscanned portions. In one version, the signal modification defines tags or trigger bits for a content control system. This modification may follow the HDTV tri-level sync (synchronization) pulses for example, and it may occur in at least one of the HDTV video channels. In another version, portions of the tri-level sync pulse are modified to cause a reference sensing circuit such an AGC system (in a receiving device such as a video recorder) to produce an erroneous output. Optionally, a signal may be added or inserted following the modified tri-level sync pulses. In another version, tri-level pseudo sync pulses are added in blanking or overscanned intervals. These tri-level pseudo sync pulses may be asymmetrical and may be followed by a signal. Further, any of the above modifications or signals or sync signals may be modulated (e.g., amplitude, position, pulse­width). Also provided are defeat methods and apparatus to reduce effects or to modify results of the modification processes.

Abstract translation: 通过修改HDTV（高分辨率电视）信号的一个或多个频道的部分来实现高清晰度电视视频内容管理和/或复制保护方法和装置。 这些修改通常处于消隐间隔中，但是可以延伸到过扫描部分。 在一个版本中，信号修改定义内容控制系统的标签或触发位。 该修改例如可以遵循HDTV三电平同步（同步）脉冲，并且可能发生在至少一个HDTV视频通道中。 在另一版本中，三电平同步脉冲的部分被修改以使诸如AGC系统（在诸如录像机的接收装置中）的参考感测电路产生错误的输出。 可选地，可以在修改的三电平同步脉冲之后添加或插入信号。 在另一个版本中，三级伪同步脉冲在消隐或过扫描间隔中被添加。 这些三电平伪同步脉冲可以是不对称的，并且可以跟随一个信号。 此外，可以调制任何上述修改或信号或同步信号（例如，幅度，位置，脉冲宽度）。 还提供了减少效果或修改修改过程的结果的失败方法和装置。

Abstract: A copy protection system and method enabling storage of copy protection information separately from protected content is disclosed. One embodiment includes a mechanism for playing a recording medium, the recording medium having stored thereon a digital content file and a copy protection information file, the mechanism producing a digital content signal from the digital content file and a copy protection signal from the copy protection file; a digital to analog converter operatively connected to the mechanism for converting the digital content signal to an analog signal; a copy protection detector connected to the mechanism for detecting a copy protection trigger present in the digital content signal; and a signal modifier connected to the copy protection detector for modifying the analog signal to include the copy protection signal in response to detection of the copy protection trigger.

Abstract: Embodiments provide methods and apparatus for simultaneous presentation of multiple media user interfaces (UIs) based on user presentation settings. In some embodiments, a user may select presentation settings for a specific combination of at least two media UIs. The presentation settings may be stored and then retrieved and used when the specific combination of the at least two media UIs are later selected to be presented simultaneously. In some embodiments, presentation settings for a media UI comprise video and/or audio settings. Video settings may include position and size of a window presenting the media UI. Audio settings may include audio volume setting of the media UI. In some embodiments, each media UI in the combination of at least two media UIs may present a different type of media content (e.g., television content, Internet content, personal content, etc.).

Abstract: A system for identification of video content in a video signal is provided via a sound track audio signal. The audio signal is processed with filtering and non linear transformations to extract voice signals from the sound track channel. The extracted voice signals are coupled to a speech recognition system to provide in text form, the words of the video content, which is later compared with a reference library of words or dialog from known video programs or movies. Other attributes of the video signal or transport stream may be combined with closed caption data or closed caption text for identification purposes. Example attributes include DVS/SAP information, time code information, histograms, and or rendered video or pictures.

Abstract: A new copy protection signal includes 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 to allow for content control effectiveness on a compliant device. The new copy protection signal also 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, or one line after, a vertical sync signal in at least one television line.
