摘要： A method and apparatus of protecting digital content within a domain is provided. if a device registered with a domain withdraws from the domain, a domain key used in the domain before withdrawal of the device is updated to a domain key which cannot be used by the device; and the domain key not exposed to the device is transmitted to a plurality of devices currently registered with the domain so that only the currently registered devices have the most recent domain key. Therefore, devices not registered with the domain and devices which previously registered with the home domain but withdrawn from the home domain can be prevented from using digital content currently shared within the domain. In addition, registered devices that withdraw from the home domain may use digital content legitimately downloaded from the home domain before they withdrew from the domain.
摘要翻译：提供一种保护域内数字内容的方法和装置。如果注册域的设备从域中退出，则在提取设备之前在域中使用的域密钥被更新为设备不能使用的域密钥; 并且未暴露于设备的域密钥被发送到当前在域中注册的多个设备，使得只有当前注册的设备具有最新的域密钥。因此，可以防止未注册到域的设备和以前在本地域注册但从归属域撤回的设备使用当前在域内共享的数字内容。此外，退出本地域的注册设备可以在他们退出域之前使用从归属域合法下载的数字内容。

摘要： A method of packaging broadcast contents are provided. The method includes: extracting a copy control bit from input broadcast contents and determining whether the broadcast contents will be stored after being encrypted based on the extracted copy control bit; creating usage rule information which includes an encryption method of the broadcast contents if it is determined that the broadcast contents will be stored after being encrypted; extracting the copy control bit from each new broadcast content sequentially input and detecting broadcast contents which include copy control bits indicating that the broadcast contents will be stored without being encrypted; and encrypting the input broadcast contents through the broadcast contents before the detected broadcast contents using the encryption method and packaging and storing the encrypted broadcast contents and the usage rule information. Therefore, the unauthorized copying of broadcast contents transmitted through a digital broadcast receiver can be prevented.
摘要翻译：提供一种封装广播内容的方法。该方法包括：从输入广播内容中提取复制控制位，并根据所提取的复制控制位确定是否在加密之后存储广播内容; 创建使用规则信息，如果确定在加密之后将存储广播内容，则包括广播内容的加密方法; 从每个新的广播内容中提取复制控制位，顺序地输入和检测包括指示广播内容将不被加密的复制控制位的广播内容; 并且通过使用加密方法的检测到的广播内容之前的广播内容来加密输入的广播内容，并且包装和存储加密的广播内容和使用规则信息。因此，可以防止通过数字广播接收机发送的广播内容的未经授权的复制。
