现就目前常用的几种主要的电视信号的加解扰技术,如非扰频加解扰技术、模拟基带加解扰技术、射频信号加解扰技术、模拟信号的数字处理加解扰技术以及数字信号加解扰技术等。在对模拟信号的数字处理加解扰技术以及数字信号加解扰技术一项加解扰技术进行性能上的分析与比较的基础上提出了射频行同步信号抑制的加解扰技术方案。
At present, several commonly used techniques for descrambling and descrambling television signals, such as unscrambler and descrambler technology, analog baseband descrambler technology, radio frequency signal descrambler technology, digital signal processing and descrambling techniques, and Digital signal descrambler technology. Based on the analysis and comparison of the performance of digital processing descramble and digital descramble and descramble of digital signal, this paper proposes the descramble and descramble scheme of radio frequency horizontal synchronization signal suppression.
