摘要
数字电视采用先进的信源（图像和声音）压缩编码技术以及先进的数字传输技术（调制／解调、纠错编码和信道自适应均衡等）。它具有很多新颖的特性，因而将有广泛的应用前景。新的数字电视体系正在诞生；它在继承现有模拟电视技术的基础上，将逐步取代现存的模拟电视体系。
Advanced source(video and audio)coding technologies and advanced digital transmission technologies(modulation/demodulation, error-correction coding and adaptive channel equalization)have been adopted in digital television,bringing to the latter many new eminent characteristics,as well as its promising prospects.A new digital television system is emerging, and it would gradually substitute the existing analogue television system, while inheritting the its technologies.
