摘要： The content distribution system according to the present invention is comprised of: a server device and a terminal device, the server device providing the terminal device with a license for using a content based on transaction processes, each including receiving of a request message, sending of a response message, and receiving of a commit message for finalizing completion of a transaction, and the terminal device controlling use of the content based on the license obtained from the server device, wherein the terminal device includes: a holding unit that holds a 1-bit transaction identification flag indicating whether a current transaction process is in progress or completed; and a sending unit that sends the transaction identification bit instead of an omitted commit message when sending a second or later request message, without sending a commit message in each transaction process except for a last transaction process in successive transaction processes, and the server device includes: a receiving unit that receives the transaction identification flag that is sent together with the second or later request message in the successive transaction processes; and a judgment unit that judges whether or not completion of one transaction should be finalized based on the received transaction identification flag.

摘要： In a right management server (100), a license data generation/updating unit (307) generates license data (900) including a use condition (503) for permitting a user to use a content based on a content use right (500) owned by the user. A subset use condition setting unit (308) sets a subset use condition (901) for temporarily invalidating the license data (900) in the license data (900). A communication unit (311) transmits the license data (900) in which the subset use condition (901) is set to the user terminal (110), and receives the license data (900) returned from the user terminal (110). Upon receipt of the invalidated license data (900), the license data generation/updating unit (307) cancels the invalidation of the license data (900) by updating the subset use condition (901).
摘要翻译：在权利管理服务器（100）中，许可数据生成/更新单元（307）生成许可数据（900），其包括使用条件（503），用于允许用户基于所拥有的内容使用权（500）使用内容由用户子集使用条件设置单元（308）设置用于临时使许可证数据（900）中的许可数据（900）无效的子集使用条件（901）。通信单元（311）将其中设置了子集使用条件（901）的许可数据（900）发送到用户终端（110），并且接收从用户终端（110）返回的许可证数据（900）。许可证数据生成/更新部（307）在接收到无效许可数据（900）后，通过更新子集使用条件（901）来取消许可证数据（900）的无效。

摘要： When a secure counter malfunction detection unit 212 deters a malfunction in a secure counter 211, a content playability judgment unit 206 performs a content playability judgment based on information managed by a malfunctioning-state playback processing management unit 214. The malfunctioning-state playback processing management unit 214 stores a malfunctioning-state playback condition composed of information such as a playback count and a playback time. The content playability judgment unit 206 judges that content is playable when the malfunctioning-state playback condition is met, and a content playback unit 210 splays the content.
