The main idea is as follow: CAS scrambles service streams at head-end with pseudorandom sequence that control words produce. At the same time, Control words are transmitted to terminal for entitled terminal to descramble and entitled users to watch program.

数字电视条件接收总的思路是：在前端对节目流进行数字加扰，同时把加扰控制字加密后传到用户端，采用一定的策略使得只有授权用户才可以解密控制字，然后在控制字的作用下解扰器对授权用户的加密数据进行解扰，使其可以收看节目。

10Gigabit Ethernet (10 GBASE-R and 10 GBASE-W) uses 64B/66B coding and decoding, which is the code format transform without the high transition density and its redundancy is small at the cost of complicated synchronization and the storage. Thus scramble is added to the 64B/66B and descramble is otherwise added before the 64B/66B decode.

它的10 GBASE-R和10 GBASE-W标准中物理编码层采用了64B/66B编解码方案。64B/66B码只是一种码的格式转换，并没有显著增加码的0、1转换密度。64B/66B编解码方案包括64B/66B码格式转换、扰码/解扰以及数据速率转换。64B/66B码冗余度很小，其代价是同步所需时间和资源相对较多。
