It is an object to provide an efficient transfer of content data. In a case of transferring the content data from a data transfer device on a primary recording medium side to a data recording device to record the content data in a secondary recording medium, a data compression system and a bit rate that are conformable to the data recording device are compared with a data compression system and a bit rate of the content data to be sent, so that a required transfer processing is brought into realization according to a result of the comparison. For instance, when both the data compression systems are equal, and the bit rate of the content data is not more than the bit rate that is conformable to the data recording device, the content data is sent as it is in an encrypted compressed data state.

Data transfer system, data transfer device, data recording device and data transfer method

A data transfer apparatus referred to as a primary-recording-medium apparatus implements proper system operations by acquisition of information on a secondary recording medium mounted on a secondary-recording-medium apparatus to serve as a destination of a transfer (or a check-out) of a content. If a medium adopting its own unique management technique as is the case with a mini disc is used as the secondary recording medium serving as a destination of a check-out, the primary-recording-medium apparatus acquires information on the secondary recording medium from the secondary-recording-medium apparatus, which is typically a data-recording apparatus. The information includes an indicator as to whether or not the secondary recording medium has been mounted on the data-recording apparatus, the name of the secondary recording medium, the name of each content stored in the secondary recording medium, the number of contents stored in the secondary recording medium and attributes of each content stored in the secondary 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.

A SDMI-compliant portable medium and a non-SDMI-compliant portable medium can be selectively connected to a licensed compliant module. When transferring copyright-protected encrypted content data from the licensed compliant module, whether the destination of transfer is the SDMI-compliant portable medium or the non-SDMI-compliant medium is determined. When the destination is found to be the SDMI-compliant portable medium, the number of times the encrypted content data can be transferred is restricted. When the destination is found to be the non-SDMI-compliant portable medium, the return (or check-in) of the encrypted content data from the non-SDMI-compliant portable medium to the licensed compliant module is disabled.

Disclosed is a method for causing either encrypted first content data or unencrypted second content data, to be selectively recorded to a storage medium in a data recording apparatus. When the data recording apparatus is to return the encrypted first content data to the data transfer apparatus, the return is inhibited if the data are judged to have been edited. Upon return of the encrypted first content data, a content ID held by the data recording apparatus regarding the first content data is matched against a content ID held by the data transfer apparatus regarding the received data. Where the encrypted first content data are known to have been edited, the content ID matching process is omitted.

A data transfer apparatus for simplifying a module structure for controlling a connected data recording apparatus and improving the processing efficiency. A control code issued by a common application module having a main purpose of check-out/check-in is made a control code corresponding to a device connected by a conversion module and transmitted via a device driver. Moreover, for example, a control code issued by a local application module having a main purpose of controlling processing depending on a device connected shares the aforementioned device driver. For example, the local application module issues a control code in a state matched with a control code format converted by the conversion module. Alternatively, the local application module issues a local control code by indicating issuance of a local control code of a format different from the control code format converted by the conversion module.
