随着国内数字电视频道的陆续开播,数字电视正以崭新的面貌进入千家万户,为人们带来了高品质的视听享受,也极大地丰富了人们的日常生活。但由于数字电视传输系统的建设主要面向城市,未能迅速触及农村及偏远地区,探究一种经济的、适合于快速建设的数字电视传输系统成为当务之急。
With the continuous launching of digital television channels in China, digital television is entering a new home with a brand new appearance, bringing high-quality audio-visual enjoyment to people and greatly enriching people’s daily life. However, due to the fact that the construction of digital television transmission system mainly faces the cities and fails to reach rural areas and remote areas rapidly, it is imperative to explore an economical digital television transmission system suitable for rapid construction.
