摘要： Embedded proprietary data, which is configured by embedding decoding key data for decoding encoded contents into proprietary data that is a subject of ownership, is recorded on a recording medium. Since the decoding key data is embedded into the proprietary data, it is difficult to separate and take out the decoding key data from the proprietary data. When copying or the like including the proprietary data is performed, it becomes possible to legally pursue a copy or the like of the proprietary data.
摘要翻译： 嵌入式专有数据被记录在记录介质上，该专有数据通过将用于将编码内容解码的解码密钥数据嵌入到作为所有权主体的专有数据中来配置。 由于解码密钥数据被嵌入到专有数据中，因此难以从专有数据分离和取出解码密钥数据。 当执行包括专有数据的复制等时，可以合法追求专有数据的副本等。

摘要： An apparatus determines whether a combination of a certificate type of a content certificate recorded on a source recording medium and a medium type of the source recording medium is a proper combination. If the combination is a proper combination, the apparatus requests a license server, which is connected to the apparatus via a network, to give approval to record content on a target recording medium. If the apparatus is a legitimate DVD recorder, the license server sends to the content recording apparatus a content certificate including on the source recording medium as the certificate type. The apparatus records the content together with the received content certificate on the target recording medium.
