摘要
利用数字电视广播信道可以实现大容量的数据传送,与互联网相比具有占用资源少、服务质量(QoS)有保证等特点,在深圳清华大学研究院数字电视前端系统紫荆神网的基础上,设计实现了比现有数据广播协议更简便的低成本数据下载终端。测试结果表明,其可以实现5Mbit/s以上的数据下载速率,实现了可移动、定时自动下载的功能。
By using the features of digital television broadcasting channel, such as mass data transmission, less resource occupied than Internet, and QoS guarantee, this system is designed base on the Redbud DTV front-end system developed by Shenzhen institute of Tsinghua university. The designed system is a low-cost data downloader using more simple protocols than current data broadcast. The testing result reveals that it can download data over 5 Mbit/s with functions of mobile and timing automatically.
