摘要： In recording video/audio information in a digital broadcasting, only when copy control information contained in the video/audio information includes a copy-once signal, a recording processing unit records the video/audio information on an optical disk by an optical disk drive. In editing the video/audio information recorded on the optical disk regardless of the copy control information, when the video/audio information read out from the optical disk has not been subjected to a processing by a CPRM signal and a period free from the processing is not longer than a predetermined time, an edition processing unit deletes a CM segment with the determination that the video/audio information corresponds to the CM segment.
摘要翻译：在数字广播中记录视频/音频信息时，仅当包含在视频/音频信息中的复制控制信息包括一次复制信号时，记录处理单元通过光盘驱动器将视频/音频信息记录在光盘上。在编辑记录在光盘上的视频/音频信息而不管复制控制信息的情况下，当从光盘读出的视频/音频信息未被CPRM信号进行处理并且没有处理的时间段是不超过预定时间，则编辑处理单元以确定视频/音频信息对应于CM片段的方式删除CM片段。

摘要： An output control (OPC) information is recorded on the magnetic tape 1 in conjunction with an MPEG stream. The OPC information is composed of two bits and is extracted from a reproduced signal by the output control circuit 9 and controls the digital interface (D. I/F) 7 and the switch circuit 11. In case a first bit of the OPC information is “0”, the output control circuit 9 makes the D. I/F 7 enabled and permits the output of a digital signal. In a case of “1”, the output control circuit 9 prohibits to output the digital signal. Further, when the second bit of the OPC information is “0”, the output control circuit 9 turns the switch circuit 11 off, preventing the output of an analog component signal. In case its “1”, the output control circuit 9 permits the output of the analog component signal.

摘要： Embodiments of the present invention include a control code read-out system in which a control code for access restriction corresponding to a playback control code of a recording medium is held in a playback apparatus, and the control code held in the playback apparatus is read-out when the recording medium is played back, and a comparison between the playback control code of the recording medium to be played back and the control code stored in the playback apparatus being made, and playback of the recording medium being performed only when there is coincidence between the two control codes. One embodiment of the system comprises a first portion for encrypting the control code of the playback apparatus and storing an encrypted control code in a control code storage portion, a second portion for read-out the encrypted control code from the control code storage portion, and decrypting, when playing back the recording medium.

摘要： Various techniques and associated embodiments are disclosed for providing defensive measures against “black boxes,” wherein the techniques utilize unconventional schemes for detecting the vertical blanking interval (VBI) of a video signal containing a copy protection signal. The unconventional schemes would be of particular interest to the black boxes, which must locate the VBI to generate a vertical rate signal in order to perform the task of illegally removing the copy protection signal. The unconventional schemes utilize the particular characteristics or peculiarities of the video signals in the VBI to detect the VBI and generate therefrom a reliable vertical or frame rate signal. The characteristics include various pulse spacings and/or pulse widths which may occur in specific lines in the VBI, and which may be detected to allow deriving the reliable vertical or frame rate signal. Alternatively, techniques for modifying the characteristic signals of the VBI also are disclosed to prevent the derivation of a correct or reliable vertical or frame rate signal utilizing the unconventional schemes of detection of previous mention. In a third alternative, the reliable vertical rate or frame signal is utilized to attenuate, defeat or otherwise modify an anti-copy protection signal or a normal video signal.

摘要： To store main information with associated additional information incorporated therein, data constituting the additional information is divided into a plurality of small-size data pieces of, e.g., one bit. Then, the respective values of particular ones of predetermined data units (e.g., bytes) constituting the main information are subjected to arithmetic operations in accordance with a predetermined algorithm containing the value of each of the data pieces as a parameter. In this way, the respective values of the particular data units in the main information are modulated in accordance with the values of the individual data pieces in the additional information; at that time, only some of the data unit values are altered with the others left unaltered. The thus-arithmetically-operated main information is stored into a storage. For reproduction of the additional information, the stored main information is read out, and the individual data pieces are reproduced from the particular data units by inversely executing the algorithm. For example, the main information includes MIDI key-on event data, program change data or control change data, waveform data, or image data, and the additional information includes letter data representative of the name of an author of a music piece in question, title of the music piece or title of an image and data representative of a data format employed.

摘要： A data IO device acquires stream data that includes CCI (copy control information) and outputs the stream data after finalizing a content of the CCI. Specifically, the data IO device sequentially acquires stream data including CCI, judges whether all stream data acquired within a predetermined time period includes the same CCI, and processes all stream data acquired during the predetermined time period in accordance with the same copy control information if judged in the affirmative.

摘要： Stationery, or other printable media, is encoded with a digital watermark. The watermark is not conspicuous to a human observer of the media, yet conveys plural bits of auxiliary information when optically scanned and digitally processed. The watermark can be formed by ink-jet printing, or otherwise. The encoded information can be used for various purposes, including authenticating the document as an original, linking to associated on-line resources, and distinguishing seemingly-identical versions of the same document (document serialization).

摘要： According to one embodiment of the invention, feeder logic is implemented as a software program stored in a machine readable medium and executed by a processor. The feeder logic is adapted to access indexing data associated with a pre-stored data unit. The pre-stored data unit including content in a scrambled format. The feeder logic is further adapted to generate a trigger data sequence and to insert the trigger data sequence into a data stream processed by a descrambler in response to detection that the content in the scrambled format cannot be descrambled by the descrambler using a currently valid descrambling key. The trigger data sequence is inserted prior to scrambled content of the pre-stored data unit to be processed.
