摘要

A BD-ROM reproduction device simultaneously executes reproduction of a title including an AV Clip and executes an application. The BD-ROM reproduction device includes a BD-J module (35) executing an application, a Playback Control Engine (32) for reproducing the AV Clip belonging to one title, and a module manager (34) controlling branching between a plurality of titles. The title includes a data management table. The data management table indicates an application read-in priority for each title. The BD-J module (35) includes a Java virtual machine (38), a local memory (29), and an application manager (36) for loading the application on a local memory (29). The application manager (36) reads in the application into the local memory (29) according to the read-in priority of each application and the memory size of the local memory (29).
