摘　　要：介绍了数字电视中间件增值业务平台结构,并对其数据轮播技术进行了改进,使交互应用能够以通用文件系统的方式广播传输。与基于对象轮播的MHP平台相比,该方案引入更小的带宽冗余,收发端实现更简单,执行效率更高。The structure of increased business supporting system for DTV middleware is introduced. And then, the improving data carousel scheme is described to enable using a generic file system mode to transmit the interactive content. Compared with the MHP scheme based on object carousel, the proposed solution has lower bandwidth redundancy, easier realization of transceiver and higher executive efficiency.

关 键 词：数据轮播 带宽冗余 中间件 交互应用
