Design of Videotex Broadcasting System Based on Data Carousel

Considering the complexity of the object carousel protocol, this solution innovatively modifies the data carousel protocol so that the hierarchical ( directory) structure can be transmitted by use of name descriptor and parent group descriptor.

该方案考虑到对象轮播协议的复杂性，在DVB数据轮播协议的基础上，通过名字描述符和父组描述符重建文件系统。
