MHEG

基本解释

The behavior of individual MHEG objects is determined with the action class.
复合类的任务是把所有必须的前述类的对象组合成一个表现。
According to the object-oriented terminology, an action-object is a message which is sent to a MHEG object.
另外，若一个单独的对象被包含或引用，每个复合对象就作为一个包容体。
Before a detailed description of the MHEG objects is given, we will briefly examine the individual elements of a presentation using a small scenario.
在给出MHEG对象的细节描述之前，我们将用一个小场景简要说明一个表现的各个元素。
The functionality of a composite object must satisfy some assumptions for the synchronized output through the MHEG engine .
复合对象必须满足一些假设以便通过MHEG引擎做同步输出。
The introductory scenario has discussed that the MHEG standard distinguishes two kinds of user interactions: selection and modification.
作为例子的场景已经讨论了MHEG标准区分的两种用户交互方式：选择和修改。
