摘要:
Copying, dubbing or reproducing copyrighted digital data can be inhibited or restricted to properly protect a copyright. AV data recorded on a pre-recorded tape is output from a reproducing unit of a first digital VCR with protective information indicating whether the copy of the AV data is inhibited or not. The protective information is input with the A/V data to a second digital VCR. Copy permission information of a blank tape loaded in the second digital VCR is discriminated and the second digital VCR records the AV data supplied from the first digital VCR based on the protective information and the copy permission information.

A data recording apparatus comprising a read section for reading image data and/or audio data recorded on a first recording medium, and a write section for recording the aforementioned read image data and/or audio data on a second recording medium. This data recording apparatus is further provided with an identification information determining section for determining whether identification information is recorded in the aforementioned recording medium or not, to ensure that, only when the aforementioned identification information determining section has determined that the identification information is recorded, the write section records the read image data/audio data on the second recording medium.

A data transfer system provided by the present invention is capable of executing proper management of content transfers with a high degree of efficiency. In a data transfer apparatus employing a primary recording medium, rights to transfer contents stored in a primary recording medium are managed, and transfer rights of contents already transferred to a secondary recording medium employed in a data-recording apparatus are managed by using a generated table for associating first content identifiers each generated by the data transfer apparatus for a content stored in the primary recording medium with a second content identifier received from the data-recording apparatus and generated by the data-recording apparatus for the content, which has already been transferred to the data-recording apparatus. Thus, even if the secondary recording medium cannot be used for recording a second content identifier (or a content ID), a content ID (a second content identifier) generated for a content can be used for identifying the content by associating the content ID (the second content identifier) with a content ID (a first content identifier) stored in the primary recording medium.

摘要:
An optical disk (100) stores operation identification information which causes a recording and reproduction apparatus (1) into which the optical disk (100) is inserted to recognize the optical disk (100) as a disk causing the recording and reproduction apparatus (1) to perform a commercial transaction over a network, and which serves as a trigger for causing the recording and reproduction apparatus (1) to perform the commercial transaction. Hence, by causing the recording and reproduction apparatus (1) to recognize the operation identification information before the contents is downloaded, it is possible to prevent important information such as personal information stored in the optical disk (100) from leaking over the network via the recording and reproduction apparatus (1). This as a result allows improvement in security against information leakage.

The information recording apparatus is at least provided with an identification means 12 for reading the utilization license information from the recording medium, and for identifying whether the recording medium is a recording medium for which the utilization of the music data is permitted, the music data obtaining means 13 for connecting to the server through the communication network, and for requiring the download of the music data to the server, an input output means 11 for selecting the musical composition or for reproducing the music data, and a data recording means 18 for recording the downloaded music data in the recording medium, and without complicated operation, the music data can simply be recorded in the recording medium.
摘要:
The present invention relates to a system and method for determining whether playing has been performed, determining the number of times that the playing has been performed, and charging fees based on the determination results (hereinafter "post-payment") after music has been provided from an on-line sound source server and has been played in users' players, such as MP3 players, so as not only to charge the users fees for multimedia files in a post-payment manner, not in a convention advance payment manner but also to overcome the problems of a conventional method of charging fees at the time when users access an on-line source server and download or play music (hereinafter "advance payment"). In particular, the present invention relates to a post-paid billing system and method wherein multimedia files are first provided to the user and fees are charged based on the number of times (including first playing that is related to the determination of whether playing has been performed) the users have played the provided multimedia files. According to the present invention, the users can play and enjoy the multimedia files at a lower price. Since the fees are clearly and correctly charged, the profit distribution between service providers and multimedia copyright holders can be easily made, whereby the copyright holders can earn the royalties. Since the multimedia files can be freely duplicated/distributed, the copyright infringement due to unauthorized duplication can be basically prevented, whereby the development of multimedia industry can be promoted.
