交互数字电视节目录制方案的研究

Recording Interactive TV: Problems and Proposals

以MHP为例提出了一种录制交互数字电视节目的方案,该方案将交互应用与音视频内容分离录制。交互应用是以DSM-CC对象轮播方式复用到传输流中的。将交互应用从传输流中抽取出来单独存储,为存储交互数字电视中出现的问题提供了解决的途径。

In this paper we propose a method of recording interactive TV, taking MHP as an example, which separates the interactivity from the A/V content. The interactivity is multiplexed in the broadcast in a DSM-CC object carousel. Taking the Interactivity out of the Transport Stream (TS) and storing it separately allows us to solve the problems related to recording interactive TV.
