结合秦皇岛市建设地面数字电视实际,重点介绍无线模拟电视逐步关闭、地面数字电视建设发展初期的技术投资策略。在地面电视模数共播阶段,从台站选址、设备兼容等基础设施建设到人员管理、技术更新培训等必须要考虑的几个问题展开讨论,力求做好模拟电视到数字电视的过渡。 Combined with the actual construction of terrestrial digital TV in Qinhuangdao City, the paper focuses on the technology investment strategy of the early stage of the development of terrestrial digital television with the gradual closure of wireless analogue television. In the stage of terrestrial television module co-broadcasting, several issues that must be considered, such as the site selection for site selection, equipment compatibility and other infrastructure construction, personnel management and technical training, should be discussed in order to make the transition from analog TV to digital television possible.
