摘要
随着国家地面电视的数字化改造进程加快,频谱的利用率获有效提升,为广电新技术、新业务、新生态提供了宝贵的频率资源。在此背景下,上海开展了下一代广播电视无线(下文简称"NGB-W")试验网络的建设,为广电无线三网融合提供一种创新解决方案。本文介绍了NGB-W系统架构以及相关试验的进展情况,同时也展望了广电无线领域的未来,从规划功能型平台的建设方向出发,提出广电+互联网、广电+物联网的业务模式,为广电的新生态提出发展建议。
Along with the acceleration of the national broadcast television digitalization process, the wireless spectrum utilization has bccn improved effectivcly. It will provide the precious frequency resources for the new technology, new busincss and new ecology in thc fields of radio and television. Under this background. Shanghai has been carried out the construction of the NGB-W trial network. This network provides an innovative solution for the triple-ptay in wireless. This paper describes the architecture of the NGB-W system and the progress of the trial network. Meanwhile it also looks forward to the future of the wireless. Starting from the direction of the function platform construction, it provides business patterns of broadcast ＋ internet and broadcast＋IoT. This paper provides the constructive suggestion about the new ecology.
