中文摘要: 针对数字电视监测系统中传输流TS的解扰问题,分析了TS流的加扰和解扰原理,提出了基于CIMAX接口芯片和大小CAM卡、同时实现两路独立TS流的解扰方案,解扰系统采用硬件和软件相结合的方式,并在数字电视监测系统中得到了成功应用.
Abstract:Digital TV system monitoring and descrambling of Transport Stream(TS) is introduced,and the principle of scrambled and descrambled TS stream is analyzed.Interface chip cards based on CIMAX and big/small CAM cards are proposed to achieve two independent TS stream.This descrambling system combines hardware and software to realize the completion of descrambling,and has been successfully used in digital television monitoring system.
