摘要： A digital work (102) and copyright management information (103) for the digital work are recorded on an information recording medium (101) by altering a shape, a position or a pattern (104,105) of recording mark edges of the digital work. Alternatively, a decryption key for the right management information is recorded on an information recording medium on which the copyright management information has been recorded encrypted, by altering the recording mark edges of the copyright management information. Alternatively, a check code for the copyright management information is recorded on the information recording medium by altering the recording mark edges. The check code is checked when the copyright management information is read, thus detecting illegal use of the copyright management information.

摘要： DVD-Video discs and playback apparatuses are assigned a region code indicating one of six regions into which the world is divided, for the purpose of protecting copyrights of content such as movies and music. However, playback apparatuses exist that illegally circumvent the function of checking the region code of the disc with the region code of the playback apparatus.The present invention provides a region restrictive viewing/listening system that enables regionally restricted viewing/listening, thereby preventing playback apparatuses which circumvent region code checking from playing back content correctly. A content recording apparatus encrypts content, based on an internally-stored region code, and records the encrypted content to a recording medium. A content playback apparatus decrypts the content, based on an internally-stored region code, and plays back the content.
摘要翻译：出于保护诸如电影和音乐的内容的版权的目的，向DVD视频盘和播放装置分配指示世界被划分成的六个区域之一的区域码。然而，现有的回放装置非法地规避了用回放装置的区域码检查盘的区域码的功能。本发明提供了一种区域限制视听系统，其能够区域限制视听，从而防止回放装置这避免了区域代码检查从正确地回放内容。内容记录装置基于内部存储的地区码对内容进行加密，并将加密的内容记录到记录介质。内容重放装置根据内部存储的区域码解密内容，并重放内容。

摘要： An input/output (IO) system reduces the processing load involved in judging whether a device is valid or revoked. The system is constituted from an input/output (IO) device and an information usage device. The IO device outputs an identifier (ID) list to the information usage device, the ID list including one or more identifiers (IDs), arranged according to a predetermined rule, that each correspond to a different valid or revoked device. The information usage device uses the received ID list to specify a target range that includes a target ID stored by the information usage device, and outputs range information indicating the specified target range to the IO device, which uses the received range information in judging whether the information usage device is valid or revoked.

摘要： An optical disc having a plurality of sectors, each of which includes a plurality of frames. Sub information bit value "0" or "1" is assigned to the plurality of frames constituting a sector, excluding the first and last frames. Edge positions are displaced so that leading/lagging errors appear in accordance with a certain rule when data fields of the frames to which sub information bit value "1" is assigned are read. Edge positions are displaced so that leading/lagging errors appear in accordance with a reversed rule of the certain rule when data fields of the frames to which sub information bit value "0" is assigned are read.
摘要翻译：一种具有多个扇区的光盘，每个扇区包括多个帧。副信息比特值“0”或“1”被分配给构成一个扇区的多个帧，不包括第一帧和最后一帧。当读取分配了子信息比特值“1”的帧的数据字段时，边缘位置被移位，从而根据一定规则出现前/后误差。当读取分配有子信息位值“0”的帧的数据字段时，边缘位置被移位，从而根据特定规则的反向规则出现前导/滞后误差。

摘要： A key distribution system distributes key data for using content to a second encryption device that has been legitimately outsourced processing by a first encryption device. The first encryption device acquires permission information indicating that the first encryption device has permission to use the content, generates certification information by making an irreversible alteration the to permission information, and transmits the permission information and the certification information to the second encryption device. The second encryption device receives the permission information and the certification information, sends them to a key distribution device, and acquires the key data from the key distribution device. The key distribution device receives the permission information and the certification information, judges whether or not the certification information was generated by the by the first encryption device, and if judging in the affirmative, transmits the key data to the second encryption device.
