用FPGA实现数字有线电视的加解扰

Encryption of Digital CATV With FPGA Devices

介绍了用 FPGA(现场可编程门阵列 )器件实现有线电视加解扰功能 ,分析了两种数字有线电视加解扰方式的基本原理和实现过程 。

An implementation of function encryption of digital CATV(Cable Television) with FPGA(Field Programmable Gate Array) is presented in this paper. The operation principles and developing processes of two kinds of digital CATV encryption modes are analyzed and compared.
