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.Digital TV system monitoring and descrambling of Transport Stream（ TS ） is intro- duced, 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 descram- bling, and has been successfully used in digital television monitoring system.
