数字电视是当前知识经济时代高科技产品的典型代表,它是数字信号处理和压缩技术、数字通信技术、计算机技术、大规模集成电路设计与制造技术、高清晰度显示技术等领域的多项数字化技术成果的结晶。在数字电视发展上,先进的西方国家凭借自己先进的技术优势,成功地突破和掌握了数字电视中的关键技术,逐渐形成了以知识产权表现出来的数字技术优势,占据了世界数字市场的巨大的份额,从而获得了巨大的高额利润。我国数字电视传输技术的发展,已成为当前业内比较关注的课题。笔者结合自身的工作实际,在本文中对数字电视传输技术进行了概述,探讨了我国当前数字电视传输技术的发展现状,展望了未来数字电视传输技术的发展趋势。 Digital television is a typical representative of high-tech products in the era of knowledge-based economy. It is one of the most advanced digital technologies in digital signal processing and compression, digital communication, computer technology, large scale integrated circuit design and manufacturing, and high definition display. The crystallization of technical achievements. In the development of digital TV, the advanced western countries have successfully broken through and mastered the key technologies in digital television by virtue of their advanced technological advantages and gradually formed the digital technology superiority represented by intellectual property, occupying a huge digital market in the world Of the share, so as to obtain a huge high profits. The development of digital television transmission technology in our country has become a topic of more concern in the current industry. In this paper, the author summarizes the digital television transmission technology, discusses the current development status of digital TV transmission technology in our country, and looks forward to the future development trend of digital television transmission technology.
