摘要： An optical disk is provided that disables reproduction of sub-information even if the sub-information as a contents encryption key is recorded entirely onto another optical disk. Sub-information is recorded on the optical disk by deforming a recording mark slightly in accordance with a pseudo random number sequence that is obtained using as an initial value medium ID that is read out medium inherent information. This allows sub-information inherent in a medium to be recorded, and even if the sub-information is duplicated entirely to another optical disk, the illegally duplicated sub-information cannot be reproduced because of a difference in initial value of a pseudo random number sequence between media.

摘要： An electronic device (e.g., a display device) (101) is connected with an external connection device (e.g., an image recording/playback device) (201), thereby to perform data communications. A controller (103) of the electronic device (101) decides, in case it receives operation information, whether or not an operation screen (GUI) for the electronic device (101) is displayed. When the operation screen is displayed, the controller (103) further decides whether or not a key (a reception key) corresponding to the received operation information is effective for the operation screen. The controller (103) performs, when the reception key is effective for the operation screen, a control responding to the reception key, and, when the reception key is not effective for the operation screen, sends the received operation information to the external connection device (201). With the operation screens of both the electronic device and the external connection device being simultaneously displayed, one remote control makes only one operative, while the operation screens of the two being prevented from simultaneously operating.

摘要： In a sector address area (5), address blocks (16, 17, 18, and 19) containing address numbers and ID numbers are alternately deviated inward and outward from the center of the track by nearly half track pitches. Therefore, the reading of addresses from a land-groove recording/reproducing type optical disk and the stability of tracking in the sector address area can be improved.

摘要： An MPEG2-PS format digital stream is composed of VOBUs and each VOBU except an RDI-Pack at the top is encrypted using a content key Kc. The content key Kc is an encryption key obtained by adding a title key Kt to CCI, and then converting a time varying coefficient using the sum. Accordingly, the resulting content key Kc differs for each VOBU. Since each content key Kc is all different for such a small unit of VOBU, copyright of the digital stream is firmly protected. CCI contained in RDI-Pack represents conditional Copy Freely status which allows the digital stream to be copied on condition that the digital stream is recorded only in encrypted form.

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.
