    • Content license storage is provided by holding, in a temporary license store on the content consumption device, a plurality of content licenses for a plurality of content streams, wherein each content license of the plurality of content licenses includes a removal date. The method further includes for each content license of the plurality of content licenses corresponding to a content stream of the plurality of content streams which is designated for archived playback, copying the content license into an embedded license store within the content stream to form an archived content stream. The method further includes removing one or more of the plurality of content licenses held at the temporary license store if the removal date included in the content license has been reached, while leaving each content license stored within an archived content stream even if the removal date has been reached.

    • Encrypted content streaming is provided by a method comprising holding an encrypted content stream that is cryptographically encrypted from a content stream with a content key, and holding an encrypted content key that is cryptographically encrypted from the content key with one or more intermediate encryption keys. The method further comprises serving the encrypted content stream to a plurality of content consumption devices, wherein the encrypted content stream is embedded with a leaf license comprising the encrypted content key, and wherein the encrypted content stream is cryptographically decryptable by a content consumption device having a scalable root license providing one or more intermediate root keys from which the content consumption device derives the one or more intermediate decryption keys paired to the one or more intermediate encryption keys.
    • 加密内容流是通过一种方法提供的,该方法包括:使用内容密钥保存从内容流加密的加密内容流,以及使用一个或多个中间加密密钥保存从内容密钥加密的加密内容密钥。 所述方法还包括将加密的内容流服务于多个内容消费设备,其中所述加密的内容流被嵌入有包括所述加密的内容密钥的叶子许可证,并且其中所述加密的内容流可由内容消费设备加密地解密,所述内容消费设备具有 提供一个或多个中间根密钥的可扩展根许可证,内容消费装置从该根密钥导出与一个或多个中间加密密钥配对的一个或多个中间解密密钥。

    • Encrypted content streaming is provided by a method comprising holding an encrypted content stream that is cryptographically encrypted from a content stream with a content key, and holding an encrypted content key that is cryptographically encrypted from the content key with one or more blackout encryption keys. Each blackout encryption key is paired to a blackout decryption key corresponding to a specific audience, and each blackout decryption key is obtainable by audiences other than the specific audience corresponding to the blackout decryption key. The method further comprises serving the encrypted content stream to the plurality of different audiences. The encrypted content stream is embedded with a leaf license comprising the encrypted content key, and the encrypted content key is cryptographically decryptable by audiences having the one or more blackout decryption keys paired to the one or more blackout encryption keys.
    • 加密内容流是通过一种方法来提供的,该方法包括:通过内容密钥保存从内容流加密的加密内容流,并且使用一个或多个中断加密密钥保存从内容密钥加密加密的加密内容密钥。 每个停电加密密钥与对应于特定观众的中断解密密钥配对,并且每个中断解密密钥可由除了中断解密密钥的特定受众以外的受众获得。 该方法还包括向多个不同的受众服务加密的内容流。 加密的内容流被嵌入具有加密的内容密钥的叶子许可证,并且加密的内容密钥由具有与一个或多个中断加密密钥配对的一个或多个中断解密密钥的受众进行密码解密。
