一种基于云计算和3G的数字化广播系统

针对传统广播覆盖有限，覆盖成本及维护成本高，容易受干扰，应急预警和信息发布能力差等问题，提出了一种基于云计算和3G的新型的数字化广播系统设计方案．该系统由播控平台、播控终端以及接收终端三部分构成，系统利用电信3G网络的基础设施，实现分组和定点广播，很好地解决了应急情况下的紧急广播问题．通过实验验证，系统具有资源集中、弹性供给、终端简化、快速部署的优点．

Digital Broadcast System Based on Cloud Computing and 3G

A new design of the digital broadcast system based on 3G means of transmission and a cloud computing is proposed to replace the traditional one, which has such disadvantages as the coverage restriction, the high covering and maintenance costs, frangibility to interference and poor capacity of emergency information dissemination. Consisting of three parts including the broadcast control platform, the control and the receiving terminal, the new system uses the 3G network infrastructure of Telecom to achieve grouping and fixed broadcasting, thus solving the urgent broadcasting issues in emergency. Experiments have shown that this system owns many advantages, such as resource pool, elastic supply, simplified terminal and rapid deployment.
