摘　　要：阐述高质量的信号服务是保证电视节目清晰、流畅播出的关键因素,但是会遇到地面数字电视前端信号受到干扰的问题,包括电磁波干扰、多路径干扰、天气产生影响、HFC光电混合网故障、SDH主干光纤环网系统故障。针对这些问题并结合实际情况,提出相应的解决办法。that high-quality signal service is a key factor in ensuring clear and smooth broadcasting of television programs. However, there may be interference issues with the front-end signals of terrestrial digital television, including electromagnetic wave interference, multipath interference, weather effects, HFC optoelectronic hybrid network failures, and SDH backbone fiber ring network system failures. It addresses these issues and proposes corresponding solutions based on the actual situation.
