摘要
作为高清晰度电视总体组在数字电视传输技术研究方面的组成部分,介绍一种由浙江大学、上海交通大学和西安电子科技大学共同提出并开发的高级数字电视广播系统(AdvancedDigitalTelevisionBroadcastingSystem,ADTB)的传输方案。该方案在功能和性能上超越现有的国外数字电视标准,能够在使用民用级调谐器的前提下,实现大容量广播数据的稳定的无线固定、便携和移动接收,支持单频网络和同频道转发,包含高效的数字有线广播传输模式,易于兼容国外标准。这是我国数字电视广播标准理想的侯选方案之一。
With the co-efforts from Zhejiang University,Shanghai Jiao Tong University and Xidian Universi-ty,a transmission scheme of the Advanced Digital Television Broadcasting System(ADTB)is presented in this paper.The simulated system functions and performance are superior to that of international DTV transmission standards.A stable fixed,portable and even mobile reception of large volume broadcasting data can be attained with a consumer grade tuner and various modulation modes.The scheme is also designed to support SFN and on-channel repeater functions,to incorporate efficient digital cable transmission modes,and to be easily compatible with some foreign standards.The presented scheme is one of the ideal candidates of DTV broadcasting standards being defined in our country.[
