Abstract

Consumer electronic devices, such as e.g. high-definition movie players for removable storage media such as optical discs, may provide possibilities for advanced interactivity for the user, implemented as software applications. A question arising generally with such software applications is what the life cycle of such an application is, and who may control it. The invention provides a method for executing software applications within a playback device for audio-video data, wherein data from a first removable storage medium are read for a software application to be executed within said playback device, and the data comprise an indication defining a termination condition for the application. Based on said termination code and depending on how the medium holding the application is ejected, the application is terminated or may survive.
