Distribution system, semiconductor memory card, receiving apparatus, computer-readable recording medium and receiving method

Abstract

A distribution server 103 distributes a content via a network, and a KIOSK terminal 105 receives the content via the network and records the content in an SD memory card 100. A customer device 111 receives a content via the SD memory card 100, checks out the content and records a copy on a recording medium. SD-Audio players 122 to 124 receive a copy of the content and play back the copy. Here, the KIOSK terminal 105 records a Usage Rule that certifies the right to control recording of content on the SD memory card 100. Move Control Information showing the number of times that moving of rights is permitted is set in the Usage Rule.

AI Technical Summary

Benefits of technology

Enables users to conveniently perform check-out and check-in of copyrighted materials on personal computers while maintaining copyright protection, preventing excessive copying and ensuring the copyright owner's profits are not unfairly reduced.

Problems solved by technology

Current distribution systems pose various obstacles to user convenience.

If copyrighted material is recorded onto a semiconductor memory card by a KIOSK terminal, however, a device other than the KIOSK terminal is not allowed to check-in the copyrighted material recorded onto the semiconductor memory card by the KIOSK terminal.

Were check-in to be performed by another device, the copyrighted material on which check-in had been performed could be checked out three or four more times. If check-in by another device and check-out by the same device were to be repeated, a large number of first generation copies would be made, and copyright protection made ineffective.
