摘要:
An NFC device according to the present invention includes the following units. An antenna unit (101) receives radio waves from a reader/writer (20) by NFC. A first power source unit (102) generates power from the radio waves. A second power source unit (104) is a drive power source. A power-supply state holding unit (107) holds information indicating a power-supply state of the second power source unit (104). An NFC unit (606) performs NFC via the antenna unit (101) to transmit the information indicating the power-supply state of the second power source unit (104). A power source switch unit (103) switches the second power source unit (104) to the first power source unit (102) according to the power-supply state of the second power source unit (104), in order to supply power to activate at least the NFC unit (606) and the power-supply state holding unit (107). Here, the power source switch unit (103) switches the second power source unit (104) to the first power source unit (102), when the information indicates that the second power source unit (104) is powered OFF.

The communication device can easily serve as an extended user interface such as a remote controller of a target apparatus without causing any complicated operations to a user. The communication device includes the following units. An apparatus information obtainment unit (203) obtains apparatus information from an apparatus. A position information obtainment unit (206) obtains position information of the communication device (102). An operation information obtainment unit (212) obtains operation information based on the apparatus information. A storage unit (213) stores the position information as apparatus position information indicating as a position of the apparatus, in association with the operation information. A direction sensor unit (207) detects direction of the communication device (102). A directional space calculation unit (208) calculates a directional space of the communication device (102). A selection unit (209a) specifies the apparatus existing in the directional space based on the apparatus position information and selects the operation information associated with the specified apparatus. An operation information transmission unit (215) transmits, based on the selected operation information, a control signal to the specified apparatus so as to allow the communication device to operate the apparatus.
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.

A terminal apparatus (M101) includes a terminal unit (M201) and a near-field communication unit (M107). The terminal unit (M201) includes a main memory (M106) that stores operation history information of the terminal apparatus (M101) and a controller (M105). The near-field communication unit (M107) includes a communication control unit (M216) that performs near-field communication with the mobile apparatus (M102) and a near-field communication memory (M215). The controller (M105) stores, in the near-field communication memory (M215), at least a part of the operation history information stored in the main memory (M106) when a malfunction of the terminal unit (M201) is detected, and the communication control unit (M216) transmits the operation history information stored in the near-field communication memory (M215) by near-field communication to the mobile apparatus (M102), in accordance with a request from the mobile apparatus (M102).
摘要:
An optical disc capable of disabling reproduction of sub-information even when the sub-information as a content encryption key is directly recorded onto another optical disc. Sub-information is recorded onto the optical disc by slightly deforming the recording mark according to the pseudo random number time series having as an initial value the medium ID which is medium unique information read out. Thus, it is possible to record sub-information unique to the medium. Even if the sub-information is copied directly to another optical disc, the initial value of the pseudo random number series varies depending on the medium and sub-information which has been copied in an unauthorized way cannot be reproduced.
