摘　　要：针对非专用数字电视设备接收加密数字电视和产品差异化的需求,设计了目前市面上唯一在解调器端处理CAS的数字电视接收方案。对数字电视的系统架构、软硬件的设计和实现方法等进行了阐述。经实验室和商用测试表明,该方案完全符合规范要求,已被条件接收系统厂商和运营商采用,并投入市场应用。In order to receive encrypted digital TV with non-dedicated DTV receiver and make differential products, a DTV solution with the only de- modulator in the market which integrates CAS module is designed. This system structure, software and hardware design and implementation are described in ,this paper. The test results and commercial trail prove that this solution complaint with standard is adopted and launched by CAS providers and broad- casting operators in the market.
