REPRODUCTION DEVICE, REPRODUCTION METHOD, REPRODUCTION PROGRAM, AND RECORDING MEDIUM.

摘要

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.
