Abstract:
PROBLEM TO BE SOLVED: To provide a service matching each of the recording medium by using the unique identification information recorded on the recording medium which is not recordable by users. SOLUTION: Unique identification information is recorded on a disk 100 in advance. The identification information is registered together with the user's right to use in a server 20 at the time of purchase or the like of the disk 100. The identification information is read when reproducing the disk 100 by an information terminal 30 and transmitted to the server 20 through the Internet 31. The server 20 generates a key to control the reproduction of the disk 100 according to the right of use matching this identification information, and sends it to the terminal 30 together with the information of the user's right to use the disk. In the terminal 30, reproduction of the disk 100 is controlled depending on the key and the user's right information transmitted from the server 20. Thus, the right to use the disk 100 is managed on every disk 100 according to the identification information, and a variety of services can be offered to each of the disks 100. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To discriminate the authenticity of identification information based on identification information recorded in a medium. SOLUTION: Received identification information is collated referring to a registered identification information list, and when it is regarded as legal identification information, specific service (service contents) prepared on the management server side is provided to a user (an identification information transmitting person). Other than that, it is regarded as illegal identification information, and alarm processing such as an alarm message display is performed without providing service information to the user. Only those who purchased data recording media legally can thereby enjoy specific service or the like. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide an information exchange system, and a method thereof, capable of reducing risk of an illegal access by unspecified others to an information processing terminal of a user. SOLUTION: To information holding devices 10A and 10B, previously registered information processing terminals TA1-TAn and TB1-TBm only are permitted to log-on. Information uploaded from the information processing terminals during their log-on is held as exchangeable information. A list of held information is added to an information list in an information list holding device 11, and the user can specify downloadable information by execution of searching by an information searching device 12 to the information list. As thus specified information is requested to be downloaded by the information processing terminal during log-on, the information holding device accepting its request reads information held in itself or information held in other information holding device to be provided to the information processing terminal requesting that.

Abstract:
PROBLEM TO BE SOLVED: To simultaneously record a plurality of management information corresponding to the kinds of reproducing apparatus to a recording medium, to judge the kinds of the apparatus when the apparatus are reproduced and to manage copying and reproducing by using the management information meeting the apparatus to be reproduced. SOLUTION: The data on the content from a CD, CD-ROM, etc., are supplied to an input terminal 1 and the number-of-copying-times management information DRM-PCM and DRM-RCN are supplied to the input terminal 2. The headers made to include the number-of-copying-times management information DRM- PCM and DRM-RCN from the input terminal 2 are supplied to an adder 10 in a header forming circuit 3. The data of the contents including the supplied headers is subjected to error correction encoding in an encoder 4 and is subjected to, for example, EFM in a modulation circuit 5. The output of the modulation circuit 5 is supplied through an RF amplifier 6 to an optical pickup 7. The data of the contents is recorded to a disk 8 by the optical pickup 7.
Abstract:
PROBLEM TO BE SOLVED: To improve convenience by selectively or simultaneously performing the reproduction of contents and speech. SOLUTION: A portable telephone set 1 for performing the speech of a radio telephone is provided with an IC card 9 for storing audio data, a speaker 10 for reproducing the audio data stored in the IC card 9, an incoming detecting part 26 for detecting incoming, and a control means for controlling the speaker 10 when the incoming is detected by the incoming detecting part 26 while the audio data stored in the IC card 9 are reproduced by the speaker 10.
Abstract:
PROBLEM TO BE SOLVED: To prevent the overflow of a memory for storing utilization history information and to surely transfer the utilization history information. SOLUTION: An audition right data charger 204 for giving audition right data to a player monitors the remaining capacity or use of capacity of a use condition log data memory. When the remaining capacity becomes 10%, for example, a message calling the transfer of a reproducing log is displayed on a display part 303 of the charger 204. When a user connects the charger 204 to a telephone line corresponding to this display, it is sensed and the user transfers the reproducing log to a settlement center automatically or while watching the indication. The charge of audition right data is inhibited for the purpose of unnecessitating the storage of new reproducing log until the reproducing log is really transferred. Besides, a display part 303a is provided for displaying the remaining capacity or use of capacity of the use condition log data memory. Further, a warning lamp 303b is provided to be turned on and flickered when the remaining capacity or use of capacity reaches a predetermined value.
Abstract:
PROBLEM TO BE SOLVED: To prevent contents, which are to be charged at the time of decoding or reproducing, from being erroneously decoded, reproduced or acquired. SOLUTION: In order to display contents to be reproduced are charged, a display part 64 is made light (lighted up) as a whole. Besides, a charging lamp 65 to emit light is provided during the time when contents to be charged are reproduced. The charging condition can be surely known by the charging lamp 65. Further, it is reported that by generating buzzer sounds through an ear receiver 62 contents are to be charged. When a charging lock switch 66 is pressed, without deciding any one of charging and free, contents can be decoded or reproduced.
Abstract:
PROBLEM TO BE SOLVED: To provide a safe and practical content reproduction time limit management system eliminating risk such as leakage of personal information of a user to the outside. SOLUTION: Inherent identification information identifying the recording medium itself is recorded in the recording medium recording content information which is the object of reproduction time limit management. At least the identification information recorded in the recording medium in such way is read by the terminal device, and it is sent to the server device. In the server device, on the basis of reproducible time limit information indicating a reproducible time limit in regard to the content information recorded in the recording medium on the basis of at least the identification information, management is carried out in regard to the reproducible time limit of the content information recorded in the recording medium. By this, when carrying out reproduction time limit management of the content recorded in the recording medium, there is no need to set registration information such as personal information of the user in a server device side as is conventional.
