摘要
现阶段,卫星技术在广播电视节目播出领域有广泛应用,并在传输技术层面占据主导地位,和传统电视节目传输形式相比,卫星技术在传输节目数量、过程稳定性及节目清晰度等诸多方面均占据优势。以卫星作为通信中继站传输电视节目时,多种主客观因素会干扰节目传输过程,可能会降低传输过程的安全性。鉴于此,本文以广播电视卫星传输为论点,探究影响传输安全性的主要因素,并有针对性地提出几点优化对策。
At this stage,satellite technology is widely used in the field of broadcasting and television programs,and it occupies a dominant position in the transmission technology,compared with traditional TV program transmission forms,satellite technology has advantages in many aspects such as the number of transmission programs,process sta⁃bility and program clarity.When a satellite is used as a communication relay station to transmit TV programs,a vari⁃ety of subjective and objective factors will interfere with the program transmission process and may reduce the securi⁃ty of the transmission process.In view of this,this paper took broadcast and television satellite transmission as the ar⁃gument,explored the main factors that affected transmission security,and proposed several optimization countermea⁃sures.
