摘要:
The invention provides an information recording medium, a storage medium, an information reproduction apparatus and method, and an information recording and reproduction apparatus and method as well as a providing medium by which information recorded on an information recording medium can be utilized only by a predetermined apparatus which corresponds to the information recording medium. A ROM has data for identification of a DVD player/recorder stored therein. A recording and reproduction section records data stored in the ROM onto a DVD and reproduces data for identification of the DVD player/recorder recorded on the DVD. A CPU controls the recording and reproduction section in accordance with the data stored in the ROM and the data reproduced by the recording and reproduction section.

摘要:
An administrative system receives unique ID information of disk from an orderer for ordering manufacture of the disks and provides the unique ID information for a disk maker. The maker stores on the disk unique attribute information of the disk including identification information for the disk maker side. The administrative system obtains normal recording information generated if normal recording is carried out when recording on the disk the unique attribute information of the disk. Alternatively, the administrative system obtains abnormal recording information generated if abnormal recording is carried out. Disk administrative information, for example, number of pieces of the disks delivered from the factory, is generated from the obtained normal and abnormal recording information.

When the user designates the reproduction of searching audio data, the designated searching audio data and audio volume data are read from a searching data recording portion. The searching audio data is reproduced corresponding to the audio volume data. When the user designates the reproduction of main audio data, the selected audio data is read from a disc and reproduced. In addition, number-of-reproduction-times data, audio volume data, audio quality data, and time period data for the designated main audio data that are updated in the searching data storing portion. The searching audio data corresponding to the designated main audio data is read from the disc corresponding to the audio quality data and the time period data and recorded to the searching data storing portion.

摘要:
The present invention provides a content-on-demand system capable of managing users' system-utilization frequencies such as download counts and connection times as well as changing the quality of a content transmitted from a server to a user in dependence on the system-utilization frequency of the user. Thus, a high-quality content or a highly functional content is provided to a user with a high system-utilization frequency. By differentiating contents provided to users in accordance with the system-utilization frequencies of the users, network businesses can be activated.
