进入21世纪,全球步入了全面信息化的时代,以数字式语音通信为主要标志的现代移动通信技术和以网络及计算机为核心的现代信息技术分别达到了前所未有的新高度。广播电视领域作为现代信息与通讯服务中不可缺失的重要组成部分,以无线数字电视广播系统为代表的新兴技术,由于其在组网、覆盖运用上的特有优势,使得其在传统广电业务拓展、数据平台广播、公共信息发布等一系列现代信息与通信服务中发挥着越来越重要的作用。今年的8月30日,酝酿已久的数字电视地面传输的国家标准正式出台,标准的确定让数字电视产业紧绷了五年之久的神经终于略显松弛。随着标准的公布,大量优势资本的介入,广播式无线数字电视系统的庞大产业链由此撬动,市场将很快进入预热期。是什么原因使得数字电视地面传输的国家标准出台吸引了除广电系统外,社会各行业如此大的关注度?本文就将从技术层面和社会应用层面探究无线数字电视系统在现代信息与通信服务中的重要作用。
Enter the 21st century, the world has entered an era of comprehensive information, digital voice communications as the main symbol of modern mobile communications technology and network and computer as the core of modern information technology reached an unprecedented new heights. As an indispensable and indispensable part of modern information and communication service, radio and television is an emerging technology represented by wireless digital television broadcasting system. Due to its unique advantages in networking and coverage, it has expanded its business in traditional broadcasting and television. Data platform broadcasting, public information dissemination and a series of modern information and communication services play an increasingly important role. August 30 this year, the long-awaited launch of the national standard for digital terrestrial television transmission formally promulgated, the standard set to make the digital television industry tension for a long time finally slacken some nerves. With the announcement of the standard and the intervention of a large number of superior capital, the huge industrial chain of the broadcast wireless digital television system will be levered and the market will soon enter a warm-up period. What makes the national standard of digital terrestrial transmission promulgated has attracted the attention of all sectors of society except broadcasting and TV system? This article will explore the wireless digital television system in the modern information and communication service from the technical level and the social application level The important role.
