摘要： In one embodiment of the invention, a system and method for receiving and correcting content is provided. A receiver receives a plurality of transmission with embedded content key identifiers. Data packets for which the receiver has a corresponding authentication key are authenticated. Non-successful authentications, or data packets without a corresponding authentication key, are ignored by the receiver. The receiver checks if the content is encrypted. If so, the content may also be decrypted using content decryption keys stored within the receiver. Authentication keys and decryption keys may be updated via secure transmissions. The receiver status is monitored for incomplete and/or corrupted content receipt. The failed content may be retransmitted to the receiver over radio transmitters. Failed content may also be supplied to the receiver via the backchannel. Retransmission of the content may be performed according to a content delivery schedule.

摘要翻译： 在本发明的一个实施例中，提供了一种用于接收和校正内容的系统和方法。 接收机接收具有嵌入的内容密钥标识符的多个传输。 对接收机具有相应认证密钥的数据包进行认证。 不成功的认证或没有相应认证密钥的数据包被接收机忽略。 接收器检查内容是否被加密。 如果是这样，也可以使用存储在接收机内的内容解密密钥对内容进行解密。 验证密钥和解密密钥可以经由安全传输来更新。 对收件人状态进行监控，以了解不完整和/或损坏的内容收据。 失败的内容可以通过无线电发射机重传到接收机。 还可以通过反向通道向接收机提供失败的内容。 可以根据内容传送时间表来执行内容的重传。
