摘要
地面数字电视广播经历了从模拟到数字的转型,在全球范围内得到广泛应用,但其仍面临覆盖、普及、互动性、传输容量与效率以及经济与政策等多方面的挑战.5G的引入为地面数字电视广播带来了新机遇.通过高效传输、信号增强、交互性提升、智能化管理与运维、创新业务模式探索以及频谱共享与资源优化等策略,5G有望助力地面数字电视广播突破现有瓶颈,实现更高质量、更广泛覆盖和更丰富的用户体验.基于此,探讨地面数字电视广播的技术现状、挑战以及5G在其中的应用方案设计.
Abstract
Terrestrial digital television broadcasting has experienced the transformation from analog to digital and has been widely used worldwide,but it still faces many challenges such as coverage,popularization,interactivity,transmission capacity and efficiency,as well as economic and policy challenges.The introduction of 5G brings new opportunities for terrestrial digital television broadcasting.Through efficient transmission,signal enhancement,interactive enhancement,intelligent management and operation and maintenance,innovative business model exploration,spectrum sharing and resource optimization and other strategies,5G is expected to help terrestrial digital television broadcasting break through the existing bottleneck,achieve higher quality,wider coverage and richer user experience.Based on this,this paper discusses the technical status and challenges of terrestrial digital television broadcasting and the application scheme design of 5G in it.
