基于个性化互动电视系统框架的单元间信息交互的实现

Implementation of Information Interaction among the Units Based on Personalized Interactive Television System

在现有HTML交互技术的技术上,实现了应用对用户数据的实时检测及根据用户数据的改变实时更新应用内容的功能。在UPnP AV框架基础上,利用UPnP设备UDN这一参数的唯一性与不变性提出了一种多UPnP设备存在情况下,UPnP设备之间实现双向数据推送的解决方案,并进行了实际测试。

The communication between assistance device and user device is based on UPnP AV architecture. The paper proposes a solution to realize the two-way data push between two UPnP devices when there are multiple devices existing via taking use of the uniqueness and stability of the deivce parameter UDN.
