摘要
综述了目前国内外常用的电视加密技术特点，提出了一种适合于卫星信道传输的实用模拟电视加密技术——双函数加密方法，并给出了实用设计框图。
In this paper the characteristics of TV scrambling techniques available both at home and abroad is overviewed and a practical analog TV scrambling technique i.e.,a dualfunction scrambling method is porposed for the transmission in satellite channels.Practical design block diagrams are also given.
