Abstract

We describe an implementation of an efficient player for MPEG-4 contents on a mobile device. The player uses 3 adaptation methods in order to support high efficiency when it plays MPEG-4 contents. The adaptation methods are composed of a physical adaptation, an event adaptation, and a resource adaptation. The first adaptation resolves the physical difference between the authoring environment and playback environment. The second adaptation resolves some events that cannot support on mobile devices. The last adaptation resolves the load for restricted resource on mobile device. In view of the results of the performance analysis on the player, we could find that the player showed an efficient playback of MPEG-4 contents on a mobile device. The applications for the player are as follows; mobile games, a car navigator, distance learning, etc.
