伴随科学技术水平的不断提升,在有线数字电视网络中大量新技术、新工艺都得到了广泛应用和推广。在电视收视效果进一步提高的同时,也对有线数字电视网络设计与维护提出了更高的要求。要做好有线数字电视维护工作,必须在充分了解有线数字电视系统组成的前提下,全面分析其设计要点,才能做好调试及维护工作,提高有线数字电视发展水平。
With the continuous improvement of science and technology, a large number of new technologies and new processes have been widely used and popularized in cable digital television networks. In the television ratings to further improve at the same time, but also on the cable digital television network design and maintenance put forward higher requirements. To do a good job of cable digital TV maintenance, we must fully understand the composition of the cable digital TV system under the premise of a comprehensive analysis of the design points in order to do debugging and maintenance work to improve the level of development of cable digital television.
