    摘要: The original content and the converted content obtained by converting the original content are encrypted by the same content key. A license containing data of use conditions such as the content key and a use period is recorded in an area of a storage medium limited for access. When the converted content is used with an external storage medium, a copy of an original license is created, a use period of the copy is changed to a use period of the converted content designated by a user, and the license is output as a converted content license to the external storage device. The use period of the original content is rewritten to prevent its overlapping with a use period defined by the converted license.

    摘要翻译: 通过转换原始内容获得的原始内容和转换内容通过相同的内容密钥进行加密。 包含诸如内容密钥和使用期限的使用条件的数据的许可证被记录在限制访问的存储介质的区域中。 当将转换的内容与外部存储介质一起使用时,创建原始许可证的副本,将复制品的使用期间改变为由用户指定的转换内容的使用期限,并且许可证被输出为转换的 外部存储设备的内容许可证。 重写原始内容的使用期限,以防止与转换的许可证定义的使用期限重叠。
