    • It is possible to realize the interactive function having a higher degree of freedom in a reproduction-dedicated optical disc having a large capacity. A virtual player model corresponding to the player function is built and it is described by Java. A BD Basic Player (210) detects a user input and a player state transition and generates an event. An object (211) having a listener interface registers in the BD Basic Player (210) an event listener corresponding to an event to be received, before generation of the event and deletes it when it has become unnecessary. When an event is generated, the BD Basic Player (210) transmits an event to an object (211) where the corresponding event listener is registered. The object (211) executes a method corresponding to the received event. It is possible to flexibly set the relationship between the event and the method and easily realize the complicated interactive function.
    • 在具有大容量的再生专用光盘中可以实现具有更高自由度的交互功能。 建立与玩家功能对应的虚拟玩家模型,并由Java描述。 BD基本播放器(210)检测用户输入和玩家状态转换并生成事件。 具有监听器接口的对象(211)在产生事件之前在BD基本播放器(210)中注册与要接收的事件相对应的事件监听器,并且当事件已变得不必要时将其删除。 当生成事件时,BD基本播放器(210)将事件发送到对应的事件监听器被注册的对象(211)。 对象(211)执行对应于接收到的事件的方法。 可以灵活设置事件与方法的关系,轻松实现复杂的交互功能。
