Abstract: The method for recording data comprised in a real time data stream sequentially on multiple recording media reduces the buffer required to temporarily store data from the data stream by starting the change of recording medium when an interruption in the program to be recorded is detected. At least part of the data during the change of recording medium is of less interest to the user and the loss of this data is thus preferred over the loss of data belonging to the program that is to be recorded. By allowing selective loss of data the buffer size is reduced.

Each Java object includes at least three methods for setting the application in an inactive state, a paused state or an active state. The carrier is also loaded with a loader application that includes a main method. The loader application controls the respective lifecyles of all Java objects present on the carrier and controls the respective methods of the Java objects. The loader application only permits one Java object to run at a time. The lifecyle of the loader application is linked to the disc and the loader application is loaded in memory when the disc is inserted in the device and killed when the disc is removed. The device runs a Java virtual machine on top of which the loader application is configured to run.

Abstract: Instead of using events stored in the datastream itself, applications can retrieve event information from the playlist on a record carrier such as DVD and blu-disc. By retrieving the event information from the playlist changes in the event information do not require reprocessing of the data stream. In addition the application knows before the start of the playback of the data stream where the events are located and what functionality in terms of resources is required. A better scheduling of resources is thus possible.

Abstract: Portable devices for rendering multimedia data objects are widely known; mainly for reproducing audio, but also for reproducing video. These devices are powered by battery, which is known to have a limited amount of energy available. This carries the risk that no energy is available any more, while a multimedia data object that is rendered, is not rendered in full this leaves a user unsatisfied. Therefore, the amount of energy of the battery is checked and when a multimedia data object selected to be rendered can be rendered in full, it is rendered. When it cannot be rendered in full, it is not rendered. In an embodiment according to the invention, this check is made for a group of selected multimedia data objects.
