摘　　要：2006年8月地面数字电视传输国家标准的正式颁布至今已有半年,包括技术试验、产品研发等在内的各项地面数字电视推广工作都在积极进行当中。为了让广大从事地面数字电视广播的技术人员对地面数字电视传输国家标准有更加细致深入的了解,在去年介绍地面数字电视传输标准的基础上(见本刊2006年第9期《地面数字电视传输国家标准概述》一文),作者再次撰文对地面数字电视传输国家标准进行全面详细的解读。The China’s national DTTV standard will be implemented since August 1st this year. Its implementation is a very arduous,complex and pressing task. A lot of problems may be faced with in the process of its concrete implementation. The authors give a full and detailed interpretation of the standard in order that the technicians engaged in DTTB would have a more meticulous and deepgoing understanding of this standard. Since the standard is only a fundamental standard in the DTTB system,the leading group of DTTB in the SARFT has established 6 working groups (for technical policy,industrial policy,program policy,frequency planning,technical standards and technical tests) ,which are formulating more than 10 supporting standards such as standards for frequency planning,system implementation,performance test,equipment requirements and so on for DTTB system. With the progress of DTTB technical tests and frequency planning in different places and with the gradual launching of relevant supporting standards the detailed introduction to and interpretation of them will be published in our Journal.
