随着科学技术的发展需要,人们的生活质量也逐步提高,人们对电视的应用也提出了更高的要求,模拟电视也慢慢的淡出人们的视线,数字电视的发展也得到的广泛的应用,同样也给电视行业的发展带来可观的利益。目前的地面数字电视传输技术作为全新的技术,因其采用的是信号调制技术,故而能够更加可靠准确的接收信号,即使是在很偏远的地区也能够在微弱的信号中使收信系统得到准确的信息,减少了家电脉冲信号的干扰,还能够抗静态多径和动态多径的干扰,这也在很大程度上使得电视直播得到空前的发展。地面数字电视传输技术在电视直播领域中的发展应用还有很多未知的问题,这些问题的解决方式亟待探索,本文重点讲述目前国内个电视台使用较多的电视直播的传输系统,这在地面数字电视传输技术的应用上具有重大意义,以供参考。
With the development of science and technology, the quality of people’s life is also gradually improved. People also put forward higher requirements on the application of television. Analog television has gradually faded away from people’s attention. The development of digital television has also been widely used , Also brings considerable benefits to the development of the television industry. The current terrestrial digital TV transmission technology as a new technology, because of its use of signal modulation technology, it can be more reliable and accurate signal reception, even in very remote areas can make the weak signal in the receiving system to be accurate Of the information, reducing the interference of household appliances pulse signal, but also anti-static multipath and dynamic multipath interference, which is also largely to make television live an unprecedented development. There are still many unknown problems in the development and application of terrestrial digital television transmission technology in the field of television broadcast. The solutions to these problems are to be explored urgently. This article focuses on the transmission systems that use more television broadcasts by domestic television stations at present, The application of transmission technology is of great significance for reference.
