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。
As an integral part of HDTV’s overall research into DTV transmission technology, this paper introduces an advanced Digital Television Broadcasting System (ADTB) proposed and developed by Zhejiang University, Shanghai Jiao Tong University and Xi’an Electronic and Science University Program. This scheme surmounts existing foreign digital television standard in function and performance, can realize stable wireless fixed, portable and mobile receiving of large-capacity broadcast data under the premise of using civilian grade tuner, support single frequency network and co-channel Forwarding, including efficient digital cable broadcast transmission mode, easy to compatible with foreign standards. This is one of the ideal candidates for the digital television broadcasting standard in our country.
