嵌入式富媒体逻辑控制的标签化脚本

摘要

通过研究富媒体场景的交互性需求,提出了一种适合嵌入式设备的富媒体场景控制脚本.该脚本采用XML标记语言描述语法,通过定义标签以及属性来表示语义,并且利用场景COM树的遍历流程进行执行,解决了场景的逻辑控制、状态恢复和终端设备能力调用的问题.该脚本可以与场景共用很多相同的模块,具有执行效率高以及消耗资源少的特点.通过与其他脚本进行的测试比较,证实了该脚本具有良好的效果.%According to the interactive requirements of rich media scene, a script for control of rich media scene in embedded environment. In this script, XML markup language is adopted to describe grammar. The semantics is represented by defining elements and attributes. The script can be executed by traversing the scene DOM tree and it resolves logic controlling, state recovering, and terminal device capabilities calling of the scene. The script can share lots of same modules with the scene, such as parsing modules and executing modules. Therefore, the script has the characteristics of high execution efficiency and low consumption of resources compared with some other existing scripts.
