摘要
聚焦广播电视播出中多频道同步播出系统的时间校准技术,阐述其发展现状,并分析其面临的外部环境、系统内部及人为因素3方面的挑战。针对这些挑战,提出相应的解决方案:采用组合式抗干扰天线、软件定义网络(Software Defined Networking,SDN)技术等应对外部环境问题;利用微机电系统(Micro-Electro-Mechanical System,MEMS)时钟校准、统一设备描述语言(Universal Device Language,UDL)等解决系统内部难题;通过多层次培训与统一标准规范克服人为因素影响。该方案可有效提升多频道同步播出时间校准的准确性与稳定性。
This paper focuses on the time calibration technology of the multi-channel synchronous broadcasting system in radio and television broadcasting,expounds its current development status,and analyzes the challenges it faces in three aspects:the external environment,the internal system,and human factors.In response to these challenges,corresponding solutions are proposed:adopting combined anti-interference antennas,Software Defined Networking(SDN)technologies,etc.to deal with external environmental problems;The internal problems of the System are solved by using clock calibration of the Micro-Electro-Mechanical System(MEMS),Universal Device Language(UDL),etc.Overcome the influence of human factors through multi-level training and unified standard norms.This scheme can effectively improve the accuracy and stability of the time calibration for multi-channel synchronous broadcasting.
