摘要
本文提出了一种用于固定格式图文电视系统的数据保护方法,并给出了具体实现流程。理论计算结果表明,采用本数据保护方法,在平均误码率P_e=10^(-3)的情况下,图文电视系统页正确率可达91.3％。
In this paper, a method for data protecting of the rigid timing framwork teletext system is presented, and the visualizing scheme for realizing it is given. The result of theoretic calculation shows that by the method, the page-correct rate can be 91.3 percent under the condition of average bit-error rate 10^(-3).
