摘要： A system for producing an output scrambled digital data stream from an input scrambled digital data stream. The input scrambled digital data stream includes a plurality of control messages (ECMs), each ECM including coded information for generating a control word (CW) associated with the ECM and being encoded using an ECM key. The input scrambled digital data stream also includes a plurality of segments of scrambled digital data, each segment of scrambled digital data being associated with one of the plurality of ECMs and being scrambled using the CW associated with the ECM. A method for producing the output scrambled digital data stream includes replacing each of the plurality of ECMs with a corresponding transformed ECM (TECM) each corresponding TECM comprising coded information for generating the CW associated with the corresponding ECM and being encoded using a TECM key, thus producing the output scrambled digital data stream, wherein the ECM key is replaced with a new ECM key at an ECM key change time, and the TECM key is not replaced at the ECM key change time.
摘要翻译： 一种用于从输入加扰的数字数据流产生输出加扰的数字数据流的系统。 输入加密的数字数据流包括多个控制消息（ECM），每个ECM包括用于生成与ECM相关联并且使用ECM密钥进行编码的控制字（CW）的编码信息。 输入加扰的数字数据流还包括多个加扰的数字数据段，加扰的数字数据的每个段与多个ECM中的一个相关联，并且使用与ECM相关联的CW加扰。 一种用于产生输出加密数字数据流的方法，包括用对应的变换ECM（TECM）代替多个ECM中的每一个，每个相应的变换ECM（TECM）对应的TECM包括用于生成与相应ECM相关联的CW并使用TECM密钥编码的编码信息，因此 产生输出加密的数字数据流，其中在ECM密钥更改时间用ECM密钥替换ECM密钥，并且在ECM密钥更改时间不替换TECM密钥。
